RESUMO
OBJECTIVE: To report the change in refractive error over 5 years following primary intraocular lens (IOL) placement by age at surgery, and to identify factors associated with the change in refractive error after 5 years. DESIGN: Prospective observational study at 61 pediatric eye care practices. PARTICIPANTS: 186 eyes of 152 children undergoing primary IOL implantation before 13 years of age for non-traumatic cataract. INTERVENTIONS: Cataract surgery with primary IOL placement MAIN OUTCOME MEASURES: Five-year change in refractive error (spherical equivalent) by age at surgery (<1 year; 1 to <2.5 years; 2.5 to <4 years; 4 to <7 years; 7 to <13 years). Five-year myopic shift in children 4 to <13 years with immediate postoperative myopia vs emmetropia or hyperopia. RESULTS: Mean spherical equivalent myopic shift (95% confidence interval [CI]) was -5.99 D (-7.64 to -4.34) when surgery was performed at 0 to <1 year of age (n=13), -3.53 D (-4.57 to -2.48) at 1 to <2.5 years (n=28), -1.91 D (-2.55 to -1.26) at 2.5 to <4 years (n=36), -2.04 D (-2.60 to -1.49) at 4 to <7 years (n=60), and -0.83 D (-1.27 to -0.40) at 7 to <13 years (n=49) (P<.01 for each comparison with the oldest group). Variability of myopic shift also decreased with increasing age (P<.01). In eyes of children 4 to <13 years (small sample size precluded analysis of children <4 years), there was significantly less mean change [95% CI] in refractive error over 5 years in eyes with myopia immediately after surgery (-0.69, 95% CI -1.48 to +0.10) than eyes with emmetropia/hyperopia immediately after surgery (-1.70, 95% CI -2.10 to -1.31) (difference = -1.01 D, 95% CI -1.89 to -0.14 D, P=.03). CONCLUSIONS: In this large, prospective cohort study of children younger than 13 years of age undergoing cataract surgery with primary IOL placement, there was greater and more variable myopic shift in children undergoing surgery at a younger age. Our finding of less myopic shift over 5 years in eyes with unintended immediate postoperative myopia deserves further study to more accurately guide IOL power selection.
RESUMO
PURPOSE: To report the cumulative incidence of complications and to describe refractive error and visual acuity (VA) outcomes in children undergoing secondary intraocular lens (IOL) implantation after previous surgery for nontraumatic cataract. DESIGN: Pediatric cataract registry. PARTICIPANTS: Eighty children (108 eyes: 60 bilateral, 48 unilateral) undergoing lensectomy at younger than 13 years of age. METHODS: Annual data collection from medical record review through 5 years after lensectomy. MAIN OUTCOME MEASURES: Cumulative incidence of newly emergent complications after secondary IOL implantation; refractive error and VA by 5 years after lensectomy. RESULTS: Median follow-up after secondary IOL implantation was 2.7 years (interquartile range [IQR], 0.8-3.3 years; range, 0.6-5.0 years) for bilateral and 2.1 years (range, 0.5-6.4 years) for unilateral cases. A common complication after secondary IOL implantation was a glaucoma-related adverse event (GRAE; glaucoma or glaucoma suspect); the cumulative incidence was 17% (95% confidence interval [CI], 3%-29%) in bilateral cases and 12% (95% CI, 0%-23%) in unilateral cases. The cumulative incidence of surgery for visual axis opacification was 2% (95% CI, 0%-7%) for bilateral cases and 4% (95% CI, 0%-10%) for unilateral cases. The median prediction error within 90 days of implantation was 0.88 diopter (D; IQR, -0.50 to +3.00 D) less hyperopic than intended among 21 eyes for bilateral cases and 1.50 D (IQR, -0.25 to +2.38 D) less among 19 unilateral cases. The median spherical equivalent refractive error at 5 years (at a median of 5.1 years of age) in eyes receiving a secondary IOL was +0.50 D (IQR, -2.38 to +2.94 D) for 48 bilateral cases and +0.06 D (IQR, -2.25 to +0.75 D) for 22 unilateral cases. Median monocular VA at 5 years was 20/63 (IQR, 20/50-20/100) for bilateral cases (n = 42) and 20/400 (IQR, 20/160-20/800) for unilateral cases (n = 33). CONCLUSIONS: Eyes with secondary IOL implantation have a risk of developing new GRAEs. Five years after lensectomy (approximately 2.5 years after secondary IOL implantation), the average refractive error was less hyperopic than desired given the anticipated further myopic shift before refraction stabilizes.

RESUMO
We evaluated whether doses of bilateral medial rectus recessions greater than Parks's tables yielded superior outcomes for adult-onset divergence insufficiency. Forty-two patients underwent bilateral medial rectus recessions. Dose was analyzed as the average total per muscle (surgery + suture adjustment if performed) and compared with the standard dose tables (based on preoperative distance esodeviation), as difference between dose performed and dose indicated by Parks's tables. Each participant was classified as having received either Parks's dose (within 0.5 mm) or a dose greater than Parks's dose. Success was defined as "rarely" or "never" diplopia in distance straight-ahead gaze and reading. For patients classified as success, the mean difference between actual surgical dose performed and Parks's dose was calculated. Success was 91% (29/32) in those receiving greater than Parks's dose versus 67% (6/9) with Parks's dose (difference = 24%; 95% CI, -5% to 60%). The mean surgical dose was 1.0 mm greater than Parks's tables for the 35 successes (at 10 weeks) versus 0.7 mm greater for the 6 failures (difference = 0.4 mm; 95% CI, -0.2 to 0.9). For medial rectus recessions in adult-onset divergence insufficiency-type esotropia, a surgical dose 1 mm greater than Parks's tables, for each muscle, is a reasonable strategy.

Importance: Increased myopic shift was found to be associated with 1 year of overminus spectacle treatment for children with intermittent exotropia (IXT). Persistence of myopic shift after discontinuing overminus spectacles is unknown. Objective: To compare refractive error change over 3 years in children with IXT originally treated with overminus vs nonoverminus spectacles. Design, Setting, and Participants: This study was an 18-month extension of the Trial of Overminus Spectacle Therapy for Intermittent Exotropia cohort, which previously randomized children aged 3 to 10 years with IXT and baseline spherical equivalent refractive error (SER) between -6.00 diopters (D) and 1.00 D to overminus spectacles (-2.50 D for 12 months, -1.25 D for 3 months, and nonoverminus for 3 months) or nonoverminus spectacles. Children were recruited from 56 sites from July 2010 to February 2022. Data were analyzed from February 2022 to January 2024. Interventions: After trial completion at 18 months, participants were followed up at 24 and 36 months. Treatment was at investigator discretion from 18 to 36 months. Main Outcomes and Measures: Change in SER (cycloplegic retinoscopy) from baseline to 36 months. Results: Of 386 children in the Trial of Overminus Spectacle Therapy for Intermittent Exotropia, 223 (57.8%) consented to 18 months of additional follow-up, including 124 of 196 (63.3%) in the overminus treatment group and 99 of 190 (52.1%) in the nonoverminus treatment group. Of 205 children who completed 36-month follow-up, 116 (56.6%) were female, and the mean (SD) age at randomization was 6.2 (2.1) years. Mean (SD) SER change from baseline to 36 months was greater in the overminus group (-0.74 [1.00] D) compared with the nonoverminus group (-0.44 [0.85] D; adjusted difference, -0.36 D; 95% CI, -0.59 to -0.12; P = .003), with 30 of 112 (26.8%) in the overminus group having more than 1 D of myopic shift compared with 14 of 91 (15%) in the nonoverminus group (risk ratio, 1.8; 95% CI, 1.0-3.0). From 12 to 36 months, mean (SD) myopic shift was -0.34 (0.67) D and -0.36 (0.66) D in the overminus and nonoverminus groups, respectively (adjusted difference, -0.001 D; 95% CI, -0.18 to 0.18; P = .99). Conclusions and Relevance: The greater myopic shift observed after 1 year of -2.50-D overminus lens treatment remained at 3 years. Both groups had similar myopic shift during the 2-year period after treatment weaning and cessation. The risk of myopic shift should be discussed with parents when considering overminus lens treatment. Trial Registration: ClinicalTrials.gov Identifier: NCT02807350.

PURPOSE: To report 8-year outcomes from a randomized controlled trial (RCT) comparing bilateral lateral rectus muscle recession (BLRc) with unilateral recession-resection (R&R) for childhood intermittent exotropia (IXT). DESIGN: Eight-year follow-up of RCT cohort. PARTICIPANTS: Of 197 randomized participants, 123 agreed to continue follow-up after the 3-year outcome visit (baseline age, 3-< 11 years; basic-type IXT, 15-40 prism diopters [Δ] by prism and alternate cover test [PACT]; baseline stereoacuity, ≤ 400 arcsec; no prior surgery). METHODS: After the RCT primary outcome at 3 years, annual follow-up from 4 through 8 years with treatment at investigator discretion. MAIN OUTCOME MEASURES: Suboptimal surgical outcome by 8 years after randomization, defined as any of the following at any visit: exotropia of 10 Δ or more by simultaneous prism cover test (SPCT) at distance or near, constant esotropia (ET) of 6 Δ or more by SPCT at distance or near, loss of near stereoacuity by 0.6 log arcsec or more from baseline, or reoperation. Secondary outcomes included (1) reoperation by 8 years and (2) complete or near-complete resolution at 8 years, defined as exodeviation of less than 10 Δ by SPCT and PACT at distance and near and 10 Δ or more reduction from baseline by PACT at distance and near, ET of less than 6 Δ at distance and near, no decrease in stereoacuity by 0.6 log arcsec or more from baseline, and no reoperation or nonsurgical treatment for IXT. RESULTS: The Kaplan-Meier cumulative probability of suboptimal surgical outcome through 8 years was 68% (55 events among 101 at risk) for BLRc and 53% (42 events among 96 at risk) for R&R (difference, 15%; 95% confidence interval [CI], -2% to 32%; P = 0.08). Complete or near-complete resolution at 8 years occurred in 15% (7/46) for BLRc and 37% (16/43) for R&R (difference, -22%; 95% CI, -44% to -0.1%; P = 0.049). The cumulative probability of reoperation was 30% for BLRc and 11% for R&R (difference, 19%; 95% CI, 2%-36%; P = 0.049). CONCLUSIONS: Despite no significant difference for the primary outcome, the 95% CI did not exclude a moderate benefit of R&R, which together with secondary outcomes suggests that unilateral R&R followed by usual care may yield better long-term outcomes than BLRc followed by usual care for basic-type childhood IXT using these surgical doses.

PURPOSE: To report 5-year outcomes after surgery for cataract associated with persistent fetal vasculature (PFV). DESIGN: Clinical cohort study using pediatric cataract registry data collected annually from medical records. METHODS: This study included 64 children <13 years of age who were undergoing surgery for unilateral, nontraumatic cataract associated with PFV. Proportions with age-normal visual acuity (VA) and VA better than 20/200 at 5 years' follow-up were estimated. Cumulative incidences of complications and additional surgeries by 5 years were calculated. Outcomes were compared between eyes with unilateral PFV and eyes with unilateral non-PFV cataract from our registry. RESULTS: Forty-eight of 64 eyes were aphakic postoperatively (median age at surgery 2 months [range 1-13 months]) and 16 were pseudophakic (29 months [range 2-92 months]). Overall, 4 of 42 eyes (10% [95% confidence interval {CI} 3%-23%]) achieved age-normal VA. VA better than 20/200 was achieved in 17 (59% [95% CI 39%-76%]) unilateral aphakic PFV eyes and 44 (43% [95% CI 32%-54%]) unilateral non-PFV aphakic eyes (age-adjusted odds ratio = 1.90 [95% CI 0.81-4.50]; P = .14). The most common complication in aphakic PFV eyes was glaucoma-related adverse events (cumulative incidence 24% [95% CI 9%-37%]). There was no significant difference in glaucoma-related adverse events between PFV and non-PFV eyes in aphakic participants ≤1 year of age at lensectomy (age-adjusted hazard ratio = 1.20 [95% CI 0.54-2.64], P = .66). CONCLUSIONS: A wide range of visual outcomes for PFV cataract were observed with a 10% probability of achieving age-normal VA. There was an ongoing risk for the development of glaucoma-related adverse events in PFV eyes.

Importance: Controlling myopia progression is of interest worldwide. Low-dose atropine eye drops have slowed progression in children in East Asia. Objective: To compare atropine, 0.01%, eye drops with placebo for slowing myopia progression in US children. Design, Setting, and Participants: This was a randomized placebo-controlled, double-masked, clinical trial conducted from June 2018 to September 2022. Children aged 5 to 12 years were recruited from 12 community- and institution-based practices in the US. Participating children had low to moderate bilateral myopia (-1.00 diopters [D] to -6.00 D spherical equivalent refractive error [SER]). Intervention: Eligible children were randomly assigned 2:1 to 1 eye drop of atropine, 0.01%, nightly or 1 drop of placebo. Treatment was for 24 months followed by 6 months of observation. Main Outcome and Measures: Automated cycloplegic refraction was performed by masked examiners. The primary outcome was change in SER (mean of both eyes) from baseline to 24 months (receiving treatment); other outcomes included change in SER from baseline to 30 months (not receiving treatment) and change in axial length at both time points. Differences were calculated as atropine minus placebo. Results: A total of 187 children (mean [SD] age, 10.1 [1.8] years; age range, 5.1-12.9 years; 101 female [54%]; 34 Black [18%], 20 East Asian [11%], 30 Hispanic or Latino [16%], 11 multiracial [6%], 6 West/South Asian [3%], 86 White [46%]) were included in the study. A total of 125 children (67%) received atropine, 0.01%, and 62 children (33%) received placebo. Follow-up was completed at 24 months by 119 of 125 children (95%) in the atropine group and 58 of 62 children (94%) in the placebo group. At 30 months, follow-up was completed by 118 of 125 children (94%) in the atropine group and 57 of 62 children (92%) in the placebo group. At the 24-month primary outcome visit, the adjusted mean (95% CI) change in SER from baseline was -0.82 (-0.96 to -0.68) D and -0.80 (-0.98 to -0.62) D in the atropine and placebo groups, respectively (adjusted difference = -0.02 D; 95% CI, -0.19 to +0.15 D; P = .83). At 30 months (6 months not receiving treatment), the adjusted difference in mean SER change from baseline was -0.04 D (95% CI, -0.25 to +0.17 D). Adjusted mean (95% CI) changes in axial length from baseline to 24 months were 0.44 (0.39-0.50) mm and 0.45 (0.37-0.52) mm in the atropine and placebo groups, respectively (adjusted difference = -0.002 mm; 95% CI, -0.106 to 0.102 mm). Adjusted difference in mean axial elongation from baseline to 30 months was +0.009 mm (95% CI, -0.115 to 0.134 mm). Conclusions and Relevance: In this randomized clinical trial of school-aged children in the US with low to moderate myopia, atropine, 0.01%, eye drops administered nightly when compared with placebo did not slow myopia progression or axial elongation. These results do not support use of atropine, 0.01%, eye drops to slow myopia progression or axial elongation in US children. Trial Registration: ClinicalTrials.gov Identifier: NCT03334253.

SIGNIFICANCE: This pilot randomized trial, the first to evaluate a specific base-in relieving prism treatment strategy for childhood intermittent exotropia, did not support proceeding to a full-scale clinical trial. Defining and measuring prism adaptation in children with intermittent exotropia are challenging and need further study. PURPOSE: This study aimed to determine whether to proceed to a full-scale trial of relieving base-in prism spectacles versus refractive correction alone for children with intermittent exotropia. METHODS: Children 3 years old to those younger than 13 years with distance intermittent exotropia control score of ≥2 points on the Intermittent Exotropia Office Control Scale (Strabismus 2006;14:147-150; 0 [phoria] to 5 [constant]), ≥1 episode of spontaneous exotropia, and 16 to 35∆ by prism-and-alternate-cover test, who did not fully prism adapt on a 30-minute in-office prism-adaptation test were randomized to base-in relieving prism (40% of the larger of distance and near exodeviations) or nonprism spectacles for 8 weeks. A priori criteria to conduct a full-scale trial were defined for the adjusted treatment group difference in mean distance control: "proceed" (≥0.75 points favoring prism), "uncertain" (>0 to <0.75 points favoring prism), or "do not proceed" (≥0 points favoring nonprism). RESULTS: Fifty-seven children (mean age, 6.6 ± 2.2 years; mean baseline distance control, 3.5 points) received prism (n = 28) or nonprism (n = 29) spectacles. At 8 weeks, mean control values were 3.6 and 3.3 points in prism (n = 25) and nonprism (n = 25) groups, respectively, with an adjusted difference of 0.3 points (95% confidence interval, -0.5 to 1.1 points) favoring nonprism (meeting our a priori "do not proceed" criterion). CONCLUSIONS: Base-in prism spectacles, equal to 40% of the larger of the exodeviations at distance or near, worn for 8 weeks by 3- to 12-year-old children with intermittent exotropia did not yield better distance control than refractive correction alone, with the confidence interval indicating that a favorable effect of 0.75 points or larger is unlikely. There was insufficient evidence to warrant a full-scale randomized trial.

Importance: Lensectomy with primary intraocular lens (IOL) implantation is often used in the management of nontraumatic pediatric cataract, but long-term data evaluating the association of age and IOL location with the incidence of complications are limited. Objective: To describe the incidence of complications and additional eye surgeries through 5 years following pediatric lensectomy with primary IOL implantation and association with age at surgery and IOL location. Design, Setting, and Participants: This prospective cohort study used Pediatric Eye Disease Investigator Group cataract registry data from 61 institution- and community-based practices over 3 years (June 2012 to July 2015). Participants were children younger than 13 years without baseline glaucoma who had primary IOL implantation (345 bilateral and 264 unilateral) for nontraumatic cataract. Data analysis was performed between September 2021 and January 2023. Exposures: Lensectomy with primary IOL implantation. Main Outcome and Measures: Five-year cumulative incidence of complications by age at surgery (<2 years, 2 to <4 years, 4 to <7 years, and 7 to <13 years) and by IOL location (sulcus vs capsular bag) were estimated using Cox proportional hazards models. Results: The cohort included 609 eyes from 491 children (mean [SD] age, 5.6 [3.3] years; 261 [53%] male and 230 [47%] female). Following cataract extraction with primary IOL implantation, a frequent complication was surgery for visual axis opacification (VAO) (cumulative incidence, 32%; 95% CI, 27%-36%). Cumulative incidence was lower with anterior vitrectomy at the time of IOL placement (12%; 95% CI, 8%-16%) vs without (58%; 95% CI, 50%-65%), and the risk of undergoing surgery for VAO was associated with not performing anterior vitrectomy (hazard ratio [HR], 6.19; 95% CI, 3.70-10.34; P < .001). After adjusting for anterior vitrectomy at lens surgery, there were no differences in incidence of surgery for VAO by age at surgery (<2 years, HR, 1.35 [95% CI, 0.63-2.87], 2 to <4 years, HR, 0.86 [95% CI, 0.44-1.68], 4 to <7 years, HR, 1.06 [95% CI, 0.72-1.56]; P = .74) or by capsular bag vs sulcus IOL fixation (HR, 1.22; 95% CI, 0.36-4.17; P = .75). Cumulative incidence of glaucoma plus glaucoma suspect by 5 years was 7% (95% CI, 4%-9%), which did not differ by age after controlling for IOL location and laterality. Conclusions and Relevance: In this cohort study, a frequent complication following pediatric lensectomy with primary IOL was surgery for VAO, which was associated with primary anterior vitrectomy not being performed but was not associated with age at surgery or IOL location. The risk of glaucoma development across all ages at surgery suggests a need for long-term monitoring.

We evaluated the effect of part-time patching versus observation on distance exodeviation control in post hoc analyses of 3- to <11-year-olds with intermittent exotropia who were assigned to either patching 3 hours/day or observation in a previously reported randomized clinical trial. The present analysis was limited to a subgroup of 306 participants who at distance fixation spontaneously manifested either a constant or intermittent exotropia or had prolonged recovery after monocular occlusion (a distance control score of 2 or worse using the 0-5 Office Control Score scale) at baseline. We assessed change in control at distance and near fixation, from baseline to 3 months and baseline to 6 months (1 month after discontinuing patching). We found greater improvement in the distance control score with patching than with observation at 3 months (mean difference, 0.4 points; 95% CI, 0.1-0.7) and 6 months (mean difference, 0.3 points; 95% CI, 0.02-0.6). These analyses suggest that part-time patching may improve distance control in children with intermittent exotropia and a control score ≥ 2; however, because this conclusion is based on post hoc subgroup analyses, further studies are needed.

Importance: Glaucoma can develop following cataract removal in children. Objective: To assess the cumulative incidence of glaucoma-related adverse events (defined as glaucoma or glaucoma suspect) and factors associated with risk of these adverse events in the first 5 years after lensectomy prior to 13 years of age. Design, Setting, and Participants: This cohort study used longitudinal registry data collected at enrollment and annually for 5 years from 45 institutional and 16 community sites. Participants were children aged 12 years or younger with at least 1 office visit after lensectomy from June 2012 to July 2015. Data were analyzed from February through December 2022. Exposures: Usual clinical care after lensectomy. Main Outcomes and Measures: The main outcomes were cumulative incidence of glaucoma-related adverse events and baseline factors associated with risk of these adverse events. Results: The study included 810 children (1049 eyes); 443 eyes of 321 children (55% female; mean [SD] age, 0.89 [1.97] years) were aphakic after lensectomy, and 606 eyes of 489 children (53% male; mean [SD] age, 5.65 [3.32] years) were pseudophakic. The 5-year cumulative incidence of glaucoma-related adverse events was 29% (95% CI, 25%-34%) in 443 eyes with aphakia and 7% (95% CI, 5%-9%) in 606 eyes with pseudophakia; 7% (95% CI, 5%-10%) of aphakic eyes and 3% (95% CI, 2%-5%) of pseudophakic eyes were diagnosed as glaucoma suspect. Among aphakic eyes, a higher risk for glaucoma-related adverse events was associated with 4 of 8 factors, including age less than 3 months (vs ≥3 months: adjusted hazard ratio [aHR], 2.88; 99% CI, 1.57-5.23), abnormal anterior segment (vs normal: aHR, 2.88; 99% CI, 1.56-5.30), intraoperative complications at time of lensectomy (vs none; aHR, 2.25; 99% CI, 1.04-4.87), and bilaterality (vs unilaterality: aHR, 1.88; 99% CI, 1.02-3.48). Neither of the 2 factors evaluated for pseudophakic eyes, laterality and anterior vitrectomy, were associated with risk of glaucoma-related adverse events. Conclusions and Relevance: In this cohort study, glaucoma-related adverse events were common after cataract surgery in children; age less than 3 months at surgery was associated with elevated risk of the adverse events in aphakic eyes. Children with pseudophakia, who were older at surgery, less frequently developed a glaucoma-related adverse event within 5 years of lensectomy. The findings suggest that ongoing monitoring for the development of glaucoma is needed after lensectomy at any age.

PURPOSE: To report 2-year ocular and developmental outcomes for infants receiving low doses of intravitreal bevacizumab for type 1 retinopathy of prematurity (ROP). METHODS: A total of 120 premature infants (mean birthweight, 687 g; mean gestational age, 24.8 weeks) with type 1 ROP were enrolled in a multicenter, phase 1 dose de-escalation study. One eye per infant received 0.25 mg, 0.125 mg, 0.063 mg, 0.031 mg, 0.016 mg, 0.008 mg, 0.004 mg, or 0.002 mg of intravitreal bevacizumab; fellow eyes when treated received one dosage level higher. At 2 years, 70 of 120 children (58%) underwent ocular examinations; 51 (43%) were assessed using the Bayley Scale of Infant and Toddler Development. RESULTS: Correlation coefficients for the association of total dosage of bevacizumab with Bayley subscales were -0.20 for cognitive (95% CI, -0.45 to 0.08), -0.15 for motor (95% CI, -0.41 to 0.14), and -0.19 for language (95% CI, -0.44 to 0.10). Fourteen children (21%) had myopia greater than -5.00 D in one or both eyes, 7 (10%) had optic nerve atrophy and/or cupping, 20 (29%) had strabismus, 8 (11%) had manifest nystagmus, and 9 (13%) had amblyopia. CONCLUSIONS: In this study cohort, there was no statistically significant correlation between dosage of bevacizumab and Bayley scores at 2 years. However, the sample size was small and the retention rate relatively low, limiting our conclusions. Rates of high myopia and ocular abnormalities do not differ from those reported after larger bevacizumab doses.

SIGNIFICANCE: When exploring relationships among clinical measures and patient-reported outcome measures in adults with convergence insufficiency, worse symptoms (Convergence Insufficiency Symptom Survey [CISS] score) seemed to be correlated with worse reading function domain score (Adult Strabismus-20 quality-of-life questionnaire). After treatment, improved symptoms were associated with improved reading function quality of life. PURPOSE: This study aimed to explore relationships between clinical measures and patient-reported outcome measures in adults undergoing treatment for symptomatic convergence insufficiency. METHODS: In a prospective multicenter observational study, we evaluated adults with symptomatic convergence insufficiency (i.e., clinical measures of near exodeviation, receded near point of convergence, reduced near positive fusional vergence; CISS score ≥21). Fifty-seven participants treated with vision therapy/exercises (n = 35) or base-in prism (n = 22) were analyzed. Spearman correlation coefficients ( R ) were used to assess associations among the three clinical measures and patient-reported outcome measures (CISS, Diplopia Questionnaire, four Adult Strabismus-20 quality-of-life domains) before treatment (baseline) and after 10 weeks and 1 year. Associations were interpreted to be present when the lower limit of the 95% confidence interval (CI) was moderate to strong ( R ≥ 0.4). RESULTS: Among multiple exploratory analyses, the only moderate to strong baseline correlation was between worse CISS and worse Adult Strabismus-20 reading function scores ( R = 0.62; 95% CI, 0.43 to 0.76). Regarding change in measures with treatment, the only moderate to strong correlations were between improved CISS and improved Adult Strabismus-20 reading function scores for prism at 10 weeks ( R = 0.78; 95% CI, 0.52 to 0.91) and 1 year ( R = 0.85; 95% CI, 0.65 to 0.94) and for vision therapy/exercises at 1 year ( R = 0.78; 95% CI, 0.57 to 0.89). CONCLUSIONS: In exploratory analyses, we found positive correlations between CISS symptom scores and reading function quality-of-life scores. The absence of correlations between symptoms and individual clinical measures is consistent with clinical experience that, in convergence insufficiency, symptoms and clinical findings can be discordant.

PURPOSE: Low-dose and very low-dose intravitreal bevacizumab (IVB) have been reported to be successful in short-term treatment of type 1 retinopathy of prematurity (ROP), down to an initial dose of 0.004 mg. We now report 12-month outcomes for these infants. DESIGN: Masked, multicenter, dose de-escalation study. PARTICIPANTS: One hundred twenty prematurely born infants with type 1 ROP. METHODS: A cohort of 120 infants with type 1 ROP in at least 1 eye from 2 sequential dose de-escalation studies of low-dose IVB (0.25 mg, 0.125 mg, 0.063 mg, and 0.031 mg) or very low-dose IVB (0.016 mg, 0.008 mg, 0.004 mg, and 0.002 mg) to the study eye; the fellow eye (if also type 1) received 1 dose level higher of IVB. After primary success or failure at 4 weeks, clinical management was at investigator discretion, including all additional treatment. MAIN OUTCOME MEASURES: Reactivation of severe ROP by 6 months corrected age, additional treatments, retinal and other ocular structural outcomes, and refractive error at 12 months corrected age. RESULTS: Sixty-two of 113 study eyes (55%) and 55 of 98 fellow eyes (56%) received additional treatment. Of the study eyes, 31 (27%) received additional ROP treatment, and 31 (27%) received prophylactic laser therapy for persistent avascular retina. No trend toward a higher risk of additional ROP treatment related to initial IVB doses was found. However, time to reactivation among study eyes was shorter in eyes that received very low-dose IVB (mean, 76.4 days) than in those that received low-dose IVB (mean, 85.7 days). At 12 months, poor retinal outcomes and anterior segment abnormalities both were uncommon (3% and 5%, respectively), optic atrophy was noted in 10%, median refraction was mildly myopic (-0.31 diopter), and strabismus was present in 29% of infants. CONCLUSIONS: Retinal structural outcomes were very good after low- and very low-dose IVB as initial treatment for type 1 ROP, although many eyes received additional treatment. The rate of reactivation of severe ROP was not associated with dose; however, a post hoc data-driven analysis suggested that reactivation was sooner with very low doses.

Importance: Intravitreal bevacizumab effectively treats severe retinopathy of prematurity (ROP), but it enters the bloodstream and may reduce serum vascular endothelial growth factor (VEGF), potentially causing detrimental effects on developing organs in the premature infant. Objective: To evaluate the association of intravitreal bevacizumab with plasma bevacizumab and VEGF concentrations at 2 and 4 weeks after predefined, de-escalating doses of intravitreal bevacizumab were administered to infants with severe ROP. Design, Setting, and Participants: This phase 1 dose de-escalation case series study was conducted at 10 US hospitals of ophthalmology institutions from May 21, 2015, to May 7, 2019. Blood samples were collected 2 and 4 weeks after intravitreal bevacizumab injection. Participants included 83 premature infants with type 1 ROP in 1 or both eyes and no previous ROP treatment. Data were analyzed from April 2017 to August 2021. Interventions: Study eyes received a single bevacizumab injection of 0.250 mg, 0.125 mg, 0.063 mg, 0.031 mg, 0.016 mg, 0.008 mg, 0.004 mg, or 0.002 mg. When the fellow eye required treatment, one dose higher was administered. Total dose administered at baseline was defined as the sum of doses given to each eye within 3 days of initial study-eye injection. Main Outcomes and Measures: Plasma bevacizumab concentration at 2 and 4 weeks after injection and the percentage change in plasma VEGF concentrations from pretreatment levels. Results: A total of 83 infants (mean [SD] age, 25 [2] weeks; 48 boys [58%]) were included in this study. Higher doses of bevacizumab administered at baseline were associated with higher plasma bevacizumab concentrations at 2 weeks (ρ, 0.53; 95% CI, 0.31-0.70) and 4 weeks (ρ, 0.44; 95% CI, 0.18-0.64). Plasma VEGF concentrations decreased by 50% or more from pretreatment levels in 40 of 66 infants (61%) at 2 weeks and 31 of 61 infants (51%) at 4 weeks, but no association was observed between the total dose of bevacizumab administered at baseline and percentage change in plasma VEGF concentrations 2 weeks (ρ, -0.04; 95% CI, -0.28 to 0.20) or 4 weeks (ρ, -0.17; 95% CI, -0.41 to 0.08) after injection. Conclusions and Relevance: Results of this phase 1 dose de-escalation case series study revealed that bevacizumab doses as low as 0.002 mg were associated with reduced plasma VEGF levels for most infants at 2 and 4 weeks after intravitreal administration; however, no association was observed between total bevacizumab dose administered and reductions in plasma VEGF levels from preinjection to 2 weeks or 4 weeks. Additional studies are needed to evaluate the long-term effects of low-dose bevacizumab on neurodevelopment and retinal structure.

SIGNIFICANCE: A rigorously designed and calibrated symptom questionnaire for childhood intermittent exotropia would be useful for clinical care and for research. PURPOSE: The aim of this study was to Rasch-calibrate and evaluate the previously developed Child Intermittent Exotropia Symptom Questionnaire using data gathered as part of a randomized clinical trial. METHODS: The questionnaire was administered to 386 children aged 3 to 10 years with intermittent exotropia who were enrolled in a randomized clinical trial comparing overminus with nonoverminus spectacles. Participants were followed at 6 and 12 months while on treatment and at 18 months off treatment. Factor analysis determined dimensionality, and Rasch analysis evaluated questionnaire performance. Logit values were converted to 0 (best) to 100 (worst). We evaluated differences in questionnaire scores between treatment groups and time points, and correlations with control scores. RESULTS: The Child Intermittent Exotropia Symptom Questionnaire was unidimensional. Rasch analysis indicated that there was no notable local dependence and no significant differential item functioning for sex or age. There was suboptimal targeting (mean logit, -1.62), and person separation was somewhat poor (0.95). There were no significant differences in the Child Intermittent Exotropia Symptom score between overminus spectacles and nonoverminus spectacles at 6, 12, and 18 months. Combining data from both treatment groups, there was significant improvement from baseline at all follow-up visits (e.g., mean change from baseline to 12 months, -6.6 points; 95% confidence interval, -8.6 to -4.6). Child Intermittent Exotropia Symptom scores were not correlated with distance or near control scores at 12 months. CONCLUSIONS: The seven-item Rasch-scored Child Intermittent Exotropia Symptom Questionnaire is limited by suboptimal performance. Future study is needed to determine whether it may be useful for clinical practice and for research.

PURPOSE: Pediatric optic neuritis (ON) is a rare disease that has not been well characterized. The Pediatric ON Prospective Outcomes Study (PON1) was the first prospective study to our knowledge aiming to evaluate visual acuity (VA) outcomes, including VA, recurrence risk, and final diagnosis 2 years after enrollment. DESIGN: Nonrandomized observational study at 23 pediatric ophthalmology or neuro-ophthalmology clinics in the United States and Canada. PARTICIPANTS: A total of 28 (64%) of 44 children initially enrolled in PON1 (age 3-<16 years) who completed their 2-year study visit. METHODS: Participants were treated at the investigator's discretion. MAIN OUTCOMES MEASURES: Age-normal monocular high-contrast VA (HCVA). Secondary outcomes included low-contrast VA (LCVA), neuroimaging findings, and final diagnoses. RESULTS: A total of 28 participants completed the 2-year outcome with a median enrollment age of 10.3 years (range, 5-15); 46% were female, and 68% had unilateral ON at presentation. Final 2-year diagnoses included isolated ON (n = 11, 39%), myelin oligodendrocyte glycoprotein-associated demyelination (n = 8, 29%), multiple sclerosis (MS) (n = 4,14%), neuromyelitis optica spectrum disease (NMOSD) (n = 3, 11%), and acute disseminated encephalomyelitis (n = 2, 7%). Two participants (7%; 95% confidence interval [CI], 1-24) had subsequent recurrent ON (plus 1 participant who did not complete the 2-year visit); all had MS. Two other participants (7%) had a new episode in their unaffected eye. Mean presenting HCVA was 0.81 logarithm of the minimum angle of resolution (logMAR) (â¼20/125), improving to 0.14 logMAR (â¼20/25-2) at 6 months, 0.12 logMAR (â¼20/25-2) at 1 year, and 0.11 logMAR (20/25-1) at 2 years (95% CI, -0.08 to 0.3 [20/20+1-20/40-1]). Twenty-four participants (79%) had age-normal VA at 2 years (95% CI, 60-90); 21 participants (66%) had 20/20 vision or better. The 6 participants without age-normal VA had 2-year diagnoses of NMOSD (n = 2 participants, 3 eyes), MS (n = 2 participants, 2 eyes), and isolated ON (n = 2 participants, 3 eyes). Mean presenting LCVA was 1.45 logMAR (â¼20/500-2), improving to 0.78 logMAR (â¼20/125+2) at 6 months, 0.69 logMAR (â¼20/100+1) at 1 year, and 0.68 logMAR (â¼20/100+2) at 2 years (95% CI, 0.48-0.88 [20/50+1-20/150-1]). CONCLUSIONS: Despite poor VA at presentation, most children had marked improvement in VA by 6 months that was maintained over 2 years. Associated neurologic autoimmune diagnoses were common. Additional episodes of ON occurred in 5 (18%) of the participants (3 relapses and 2 new episodes).

PURPOSE: To determine whether smartphone photographs of children's eyelids are reliable for diagnosing the presence of chalazia. METHODS: In this prospective cross-sectional study, 60 participants, 7 months to 16.5 years of age, at four sites were enrolled; all participants had a chalazion measuring at least 2 mm on at least one eyelid based on an in-person clinical examination by a pediatric eye care professional. Smartphone photographs taken by the parent during the office visit were uploaded to the study website. A masked reader assessed each photograph for the presence or absence of chalazia; results were compared with the gold standard clinical examination results. Sensitivity and specificity for the presence of chalazion by eyelid were calculated. RESULTS: Photographs were available for 240 eyelids; 85 had at least one chalazion and 155 were without a chalazion based on clinical examination. The masked reader correctly classified 68 of 85 eyelids with at least one chalazion and 151 of 155 eyelids without chalazia for a sensitivity of 80% (95% CI, 72%-86%) and a specificity of 97% (95% CI, 94%-99%). Sensitivity improved to 89% for chalazia 5 mm or larger and 94% when superficially located within the eyelid. CONCLUSIONS: Parental smartphone photographs appear to be useful in assessing chalazia in children as an alternative to in-office follow-up examinations. These photographs may be a valuable outcome measure in future clinical trials of chalazia treatment, especially when assessing larger lesions.

IMPORTANCE: Cataract is an important cause of visual impairment in children. Data from a large pediatric cataract surgery registry can provide real-world estimates of visual outcomes and the 5-year cumulative incidence of adverse events. OBJECTIVE: To assess visual acuity (VA), incidence of complications and additional eye operations, and refractive error outcomes 5 years after pediatric lensectomy among children younger than 13 years. DESIGN, SETTING, AND PARTICIPANTS: This prospective cohort study used data from the Pediatric Eye Disease Investigator Group clinical research registry. From June 2012 to July 2015, 61 eye care practices in the US, Canada, and the UK enrolled children from birth to less than 13 years of age who had undergone lensectomy for any reason during the preceding 45 days. Data were collected from medical record reviews annually thereafter for 5 years until September 28, 2020. EXPOSURES: Lensectomy with or without implantation of an intraocular lens (IOL). MAIN OUTCOMES AND MEASURES: Best-corrected VA and refractive error were measured from 4 to 6 years after the initial lensectomy. Cox proportional hazards regression was used to assess the 5-year incidence of glaucoma or glaucoma suspect and additional eye operations. Factors were evaluated separately for unilateral and bilateral aphakia and pseudophakia. RESULTS: A total of 994 children (1268 eyes) undergoing bilateral or unilateral lensectomy were included (504 [51%] male; median age, 3.6 years; range, 2 weeks to 12.9 years). Five years after the initial lensectomy, the median VA among 701 eyes with available VA data (55%) was 20/63 (range, 20/40 to 20/100) in 182 of 316 bilateral aphakic eyes (58%), 20/32 (range, 20/25 to 20/50) in 209 of 386 bilateral pseudophakic eyes (54%), 20/200 (range, 20/50 to 20/618) in 124 of 202 unilateral aphakic eyes (61%), and 20/65 (range, 20/32 to 20/230) in 186 of 364 unilateral pseudophakic eyes (51%). The 5-year cumulative incidence of glaucoma or glaucoma suspect was 46% (95% CI, 28%-59%) in participants with bilateral aphakia, 7% (95% CI, 1%-12%) in those with bilateral pseudophakia, 25% (95% CI, 15%-34%) in those with unilateral aphakia, and 17% (95% CI, 5%-28%) in those with unilateral pseudophakia. The most common additional eye surgery was clearing the visual axis, with a 5-year cumulative incidence of 13% (95% CI, 8%-17%) in participants with bilateral aphakia, 33% (95% CI, 26%-39%) in those with bilateral pseudophakia, 11% (95% CI, 6%-15%) in those with unilateral aphakia, and 34% (95% CI, 28%-39%) in those with unilateral pseudophakia. The median 5-year change in spherical equivalent refractive error was -8.38 D (IQR, -11.38 D to -2.75 D) among 89 bilateral aphakic eyes, -1.63 D (IQR, -3.13 D to -0.25 D) among 130 bilateral pseudophakic eyes, -10.75 D (IQR, -20.50 D to -4.50 D) among 43 unilateral aphakic eyes, and -1.94 D (IQR, -3.25 D to -0.69 D) among 112 unilateral pseudophakic eyes. CONCLUSIONS AND RELEVANCE: In this cohort study, development of glaucoma or glaucoma suspect was common in children 5 years after lensectomy. Myopic shift was modest during the 5 years after placement of an intraocular lens, which should be factored into implant power selection. These results support frequent monitoring after pediatric cataract surgery to detect glaucoma, visual axis obscuration causing reduced vision, and refractive error.
