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
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: 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 investigated the frequency of sensory monofixation in patients with adult-onset divergence insufficiency esotropia and whether preoperative sensory monofixation was associated with surgical failure. Twenty-five patients with esotropia greater at distance than near who underwent bilateral medial rectus recessions were included. Near stereoacuity was measured preoperatively and 8 weeks postoperatively using the Randot Preschool test. Patients with best-corrected visual acuity worse than 0.3 logMAR in either eye or preoperative diplopia "rarely" or "never" in straight-ahead gaze at distance were excluded to minimize the inclusion of decompensated childhood strabismus. Sensory monofixation was defined as stereoacuity of 200 arcsec or worse and bifixation as 40 or 60 arcsec. Surgical failure was defined as esodeviation of >4Δ or exodeviation of >10Δ at distance or near, assessed 8 weeks (range, 6-17 weeks) postoperatively. We calculated the frequency of monofixation and surgical failure rates among patients with preoperative monofixation and those with preoperative bifixation. Preoperatively, sensory monofixation was common in divergence insufficiency-type esotropia (16 of 25 [64%]; 95% CI, 45%-83%). None of those with preoperative sensory monofixation had surgical failure, which does not support an association of surgical failure with preoperative monofixation.

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.

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.

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: To determine proportions of children with strabismus with below-normal Pediatric Eye Questionnaire (PedEyeQ) scores. METHODS: Ninety-eight children with strabismus (70 aged 5-11 years; 28 aged 12-17 years) were evaluated. Children completed the Child 5-11 or 12-17 PedEyeQ (Functional Vision, Bothered by Eyes/vision, Social, and Frustration/worry domains). Parents completed the Proxy (same domains plus Eye Care) and Parent PedEyeQ (Impact on Parent and Family, Worry about Child's Eye Condition, Worry about Child's Self-perception and Interactions, and Worry about Functional Vision domains). Previously published normal (5th percentile) thresholds were applied to calculate proportions with below-normal scores for each domain. RESULTS: For the Child PedEyeQ more than 20% of 5- to 11-year-olds scored below normal, on all but the Social domain, whereas more than 50% of 12- to 17-year-olds scored below normal on all domains. On the Proxy PedEyeQ, more than 50% scored below normal on all domains when parents reported on 5- to 11-year-olds and 12- to 17-year-olds. For the Parent PedEyeQ, more than 50% of the parents of both 5- to 11-year-olds and 12- to 17-year-olds scored below normal on all domains. CONCLUSIONS: The majority of children with strabismus have below-normal PedEyeQ scores, particularly children aged 12-17 years.

A test of suppression was developed to provide a standardized approach to detecting and grading density of suppression in children with intermittent exotropia when manifestly exotropic. This new Office Suppression Test is a three-step procedure to grade suppression on a 4-point scale (from 0 for "negligible suppression" to 3 for "dense suppression"). The test was performed in 57 children 3-13 years of age with intermittent exotropia (distance angle of 16Δ-35Δ, with spontaneous tropia) during enrollment in a randomized trial. Of the 57 children, 51 could complete testing: 28 (55%) had dense suppression, 12 (24%) had moderate suppression, 5 (10%) had mild suppression, and 6 (12%) had negligible suppression. In a subgroup of 20 untreated children, suppression was evaluated again at 8 weeks. There was moderate agreement between suppression scores at baseline and at 8 weeks (weighted κ = 0.65 [95% CI, 0.45-0.84]).

BACKGROUND: The clinical management of intermittent exotropia (X(T)) has been discussed extensively in the literature, yet there remains a lack of clarity regarding indications for intervention, the most effective form of treatment, and whether there is an optimal time in the evolution of the disease at which any given treatment should be carried out. OBJECTIVES: The objective of this review was to analyze the effects of various surgical and non-surgical treatments in randomized controlled trials (RCTs) of participants with intermittent exotropia, and to report intervention criteria and determine whether the treatment effect varies by age and subtype of X(T). SEARCH METHODS: We searched the Cochrane Central Register of Controlled Trials (CENTRAL; 2021, Issue 1), which contains the Cochrane Eyes and Vision Trials Register; Ovid MEDLINE; Ovid Embase; Latin American and Caribbean Health Science Information database (LILACS); the ISRCTN registry; ClinicalTrials.gov, and the WHO ICTRP. The date of the search was 20 January 2021. We performed manual searches of the British Orthoptic Journal up to 2002, and the proceedings of the European Strabismological Association (ESA), International Strabismological Association (ISA), and American Association for Pediatric Ophthalmology and Strabismus meeting (AAPOS) up to 2001. SELECTION CRITERIA: We included RCTs of any surgical or non-surgical treatment for intermittent exotropia. DATA COLLECTION AND ANALYSIS: We followed standard Cochrane methodology. MAIN RESULTS: We included six RCTs, four of which took place in the United States, and the remaining two in Asia (Turkey, India). A total of 890 participants with basic or distance X(T) were included, most of whom were children aged 12 months to 10 years. Three of these six studies were from the 2013 version of this review. Overall, the included studies had a high risk of performance bias as masking of participants and personnel administering treatment was not possible. Two RCTs compared bilateral lateral rectus recession versus unilateral lateral rectus recession with medial rectus resection, but only one RCT (n = 197) reported on the primary outcomes of this review. Bilateral lateral rectus recession likely results in little difference in motor alignment at near (MD 1.00, 95% CI -2.69 to 4.69) and distance (MD 2.00, 95% CI -1.22 to 5.22) fixation as measured in pupillary distance using PACT (moderate-certainty evidence). Bilateral lateral rectus recession may result in little to no difference in stereoacuity at near fixation (risk ratio (RR) 0.77, 95% CI 0.35 to 1.71), adverse events (RR 7.36, 95% CI 0.39 to 140.65), or quality of life measures (low-certainty evidence). We conducted a meta-analysis of two RCTs comparing patching (n = 249) with active observation (n = 252), but were unable to conduct further meta-analyses due to the clinical and methodological heterogeneity in the remaining trials. We found evidence that patching was clinically more effective than active observation in improving motor alignment at near (mean difference (MD) -2.23, 95% confidence interval (CI) -4.02 to -0.44) and distance (MD -2.00, 95% CI -3.40 to -0.61) fixation as measured by prism and alternate cover test (PACT) at six months (high-certainty evidence). The evidence suggests that patching results in little to no difference in stereoacuity at near fixation (MD 0.00, 95% CI -0.07 to 0.07) (low-certainty evidence). Stereoacuity at distance, motor fusion test, and quality of life measures were not reported. Adverse events were also not reported, but study authors explained that they were not anticipated due to the non-surgical nature of patching. One RCT (n = 38) compared prism adaptation test with eye muscle surgery versus eye muscle surgery alone. No review outcomes were reported. One RCT (n = 60) compared lateral rectus recession and medial rectus plication versus lateral rectus recession and medial rectus resection. Lateral rectus recession and medial rectus plication may not improve motor alignment at distance (MD 0.66, 95% CI -1.06 to 2.38) (low-certainty evidence). The evidence for the effect of lateral rectus recession and medial rectus plication on motor fusion test performance is very uncertain (RR 0.92, 95% CI 0.48 to 1.74) (very low-certainty evidence). AUTHORS' CONCLUSIONS: Patching confers a clinical benefit in children aged 12 months to 10 years of age with basic- or distance-type X(T) compared with active observation. There is insufficient evidence to determine whether interventions such as bilateral lateral rectus recession versus unilateral lateral rectus recession with medial rectus resection; lateral rectus recession and medial rectus plication versus lateral rectus recession and medial rectus resection; and prism adaptation test prior to eye muscle surgery versus eye muscle surgery alone may confer any benefit.

Twenty adolescents (12-17 years old) with diplopic strabismus and 20 with nondiplopic strabismus (matched to diplopic subjects for direction and magnitude of ocular deviation) completed the Pediatric Eye Questionnaire (PedEyeQ). Children completed the Child PedEyeQ, and one parent for each child completed the Proxy PedEyeQ and Parent PedEyeQ. PedEyeQ Rasch domain scores were calculated and converted to a scale of 0 (worst) to 100 (best). Distributions of domain scores were compared between diplopic and nondiplopic cohorts using Wilcoxon tests. Diplopic adolescents had significantly lower Child PedEyeQ scores on Functional Vision (72 vs 90; P = 0.008), Bothered by Eyes/Vision (65 vs 90; P = 0.009), and Frustration/Worry (53 vs 75; P < 0.001) domains. There was no difference on the Child Social domain (85 vs 90; P = 0.22). Proxy and Parent PedEyeQ scores were similar between diplopic and nondiplopic cohorts (P > 0.06 for each comparison). These findings highlight the importance of addressing diplopia when managing childhood strabismus.

Patient-reported outcome measures such as the Pediatric Eye Questionnaire (PedEyeQ) are increasingly recognized as important in healthcare assessment. Defining normal PedEyeQ thresholds would allow classification of individual children as having reduced versus normal domain scores. We prospectively enrolled visually normal children (aged 0-17 years; n = 310) to calculate normal PedEyeQ domain thresholds. In addition, 48 children with bilateral visual impairment (VI; best-eye acuity worse than 20/70 or 20/70 or better with limited visual fields) were enrolled for validation. The Child PedEyeQ (four domains) was completed by 5- to 17-year-olds. Parents completed Proxy (five domains) and Parent PedEyeQ (four domains). Each domain was Rasch scored (converted to 0-100); normal thresholds were defined as the 5th percentile of scores in visually normal controls. For Child 5-11 PedEyeQ, 39%-78% of VI children had reduced domain scores, and 88%-100% for 12- to 17-year-olds. For Proxy PedEyeQ, proportions ranged from 55% to 100% and for Parent PedEyeQ ≥83% had reduced scores. High prevalence of reduced PedEyeQ domain scores in the VI cohort, validates the use of normal thresholds. Nevertheless, variability in child self-reporting creates challenges for identifying individual 5- to 11-year-olds with reduced scores.

PURPOSE: To investigate health-related quality of life (HRQOL) after strabismus surgery in children with intermittent exotropia (IXT) and relationships between HRQOL and surgical success. METHODS: A total of 197 children with IXT aged 3-11 years (and 1 parent of each child) were enrolled in a previously reported randomized clinical trial comparing two surgical procedures. The Intermittent Exotropia Questionnaire (IXTQ) was administered before surgery (baseline), and again at 6 and 36 months following surgery. The child version of the IXTQ was only completed by children 5-11 years of age (n = 123). Outcomes were classified as "resolved" (exodeviation of <10Δ, no decreased stereoacuity, and no other nonsurgical treatment for IXT or reoperation), "suboptimal" (exotropia ≥10Δ by simultaneous prism and cover test or constant esotropia ≥6Δ or loss of ≥2 octaves of stereoacuity), or "intermediate." Mean changes in Rasch-calibrated IXTQ domain scores (Child, Proxy, Parent-psychosocial, Parent-function, and Parent-surgery; converted to a 0-100 scale) were compared. RESULTS: Overall, mean IXTQ domain scores improved for all domains from baseline to 36 months after surgery, ranging from 10.7 points (Child IXTQ; P < 0.0001) to 34.5 points (Parent-surgery IXTQ; P < 0.0001). At 36 months after surgery, 62 (39%) children had resolved IXT, whereas 38 (24%) had suboptimal outcome. Greater improvement was found in all mean domain scores with resolved IXT (range, 19.8-46.0 points) compared with suboptimal outcome (all comparisons P < 0.05). CONCLUSIONS: Successful surgery for childhood IXT results in measurable improvement in a child's quality of life, in parental assessment of the child's quality of life, and in quality of life for the parent.

PURPOSE: To determine whether health-related quality of life (HRQOL) scores improved or worsened over 3 years of observation in childhood intermittent exotropia without treatment. METHODS: A total of 111 children aged 3-11 years with intermittent exotropia were assigned to observation in a previously reported randomized trial comparing patching with observation. The intermittent exotropia questionnaire (IXTQ) was administered at baseline, 6 months, and 36 months. Rasch-calibrated IXTQ domain scores (Child, Proxy, Parent-psychosocial, Parent-function, and Parent-surgery) were compared between time points. The Child IXTQ was administered only to children ≥5 years of age (n = 78). RESULTS: Overall, Child IXTQ and Proxy IXTQ scores showed no significant change over 36 months (mean improvement from baseline to 36 months of 3.2 points [95% CI, -1.9 to 8.2] and -2.4 points [95% CI: -7.9 to 3.1], resp.). By contrast, Parent-psychosocial, Parent-function, and Parent-surgery domain scores all improved over 36 months (mean improvements of 12.8 points [95% CI, 5.9-19.6] and 14.2 points [95% CI, 8.0-20.3] and 18.5 points [95% CI, 9.7-27.3], resp.). CONCLUSIONS: HRQOL of children with intermittent exotropia remains stable with observation over 3 years (by both child and proxy report), whereas parental HRQOL improves.

PURPOSE: To evaluate eye-related quality of life (ER-QOL) and functional vision across a wide range of pediatric eye conditions, using the Pediatric Eye Questionnaires (PedEyeQ). METHODS: A total of 1,037 children with an eye condition and 254 visually normal controls, across 0-4, 5-11, and 12-17 years age groups, completed the following questionnaires: Child PedEyeQ (Functional Vision, Bothered by Eyes/Vision, Social, Frustration/Worry domains), Proxy PedEyeQ (same domains plus Eye Care), and Parent PedEyeQ (Impact on Parent and Family, Worry about Child's Eye Condition, Worry about Child's Self-perception and Interactions, and Worry about Functional Vision domains). The primary eye condition was classified as amblyopia (n = 171), cataract (n = 99), cerebral visual impairment (CVI; n = 50), cornea (n = 20), eyelid (n = 35), glaucoma (n = 24), nystagmus (n = 57), orbital (n = 19), pupil/iris (n = 7), refractive error (n = 119), retina (n = 82), strabismus (n = 332), and uveitis (n = 22). RESULTS: PedEyeQ domain scores (scaled 0-100) were significantly worse across eye conditions, compared with controls. Child PedEyeQ greatest differences were on the Bothered by Eyes/Vision domain (nystagmus 5-11 years, -26 points [95% CI, -39 to -12]; nystagmus 12-17 years, -45 [95% CI, -61 to -28]). Proxy PedEyeQ differences were greatest on Functional Vision (CVI 0-4 years, -45 [95% CI, -56 to -34]; CVI 5-11 years, -58 [95% CI, -72 to -43]; nystagmus 12-17 years, -50 [95% CI, -69 to -31]). Parent PedEyeQ differences were greatest on Worry about Child's Functional Vision (CVI 0-4 years, -64; 95% CI -77 to -50). CONCLUSIONS: The PedEyeQ detects reduced ER-QOL and functional vision across pediatric eye conditions, and across age groups, indicating its utility for clinical practice and clinical trials.

PURPOSE: To compare the double-Maddox rod test with other methods of measuring cyclodeviation DESIGN: Retrospective cohort study. METHODS: We retrospectively identified 153 adults in a clinical practice with cyclodeviation assessed using double-Maddox rods, of whom 105 were also assessed using fusible synoptophore targets, 73 using nonfusible synoptophore targets, 118 using single-Maddox rod, and 43 using fundus photography. Relationships between double-Maddox rod and other tests were evaluated by calculating mean differences with 95% confidence intervals (CI), intraclass correlation coefficients (ICC), and Bland-Altman plots with linear regression. RESULTS: Synoptophore cross-in-circle targets and the largest (of right or left) single-Maddox rod values were similar to double-Maddox values (mean differences: -1.2° and 0.1°, respectively; ICC: 0.79 and 0.82, respectively). Synoptophore house targets measured less excyclodeviation (mean difference: -2.7°; ICC: 0.71). Mean summed single-Maddox rod values were somewhat similar to double-Maddox values (mean difference: 1.5°; ICC: 0.85), but differences increased with greater cyclodeviation (r2 = 0.2678; P < .001). Fundus photographs showed large, uncorrelated differences compared with double-Maddox rod test, when summing right and left eyes and when using the largest of right or left (mean differences: 12.2° and 6.2°; ICC: -0.02 and 0.21, respectively), and differences increased with greater cyclodeviation (r2 = 0.4094; P < .001 and r2 = .1143; P= .03, respectively). CONCLUSIONS: There was good agreement between double-Maddox and the largest single- Maddox test values and synoptophore cross-in-circle targets but poorer agreement with other tests. Further study is needed to understand which measurements best reflect true cyclodeviation and relationships with symptoms.

PURPOSE: We evaluated relationships between visual acuity (VA) and eye-related quality of life and functional vision in children, across a spectrum of pediatric eye conditions, using the Pediatric Eye Questionnaire (PedEyeQ). DESIGN: Cross-sectional study. METHODS: Three hundred ninety-seven children (5-11 years of age) with an eye condition and 104 visually normal control subjects completed the Child PedEyeQ (functional vision, bothered by eyes/vision, social, and frustration/worry domains). One parent for each child completed the Proxy PedEyeQ (same domains as child plus eye care) and parent PedEyeQ (impact on parent and family, worry about child's eye condition, worry about child's self-perception and interactions, and worry about functional vision domains). Each domain was Rasch-scored and Spearman rank correlations were calculated to evaluate relationships between better-seeing-eye and worse-seeing-eye VA and PedEyeQ domain score. RESULTS: There was a significant relationship between poorer better-seeing-eye VA and lower (worse) PedEyeQ score on 2 of 4 child domains (e.g., functional vision, r = -0.1474; P = .005), on 2 of 5 proxy PedEyeQ domains (e.g., functional vision, r = -0.2183; P < .001), and on 2 of 4 parent PedEyeQ domains (e.g., impact on parent and family, r = -0.1607; P = .001). Worse-seeing-eye VA was associated with lower PedEyeQ scores across all child, proxy and parent domains (P < .01 for each) with the exception of the child social domain (P = .15). CONCLUSIONS: Both better-seeing-eye and worse-seeing-eye VA were associated with functional vision and eye-related quality of life in children, assessed using the PedEyeQ, although other factors may also influence relationships. These data further validate using the PedEyeQ across pediatric eye conditions.

Importance: Patients with epiretinal membrane (ERM) sometimes close 1 eye for improved vision, but associations have not been rigorously studied. Objective: To evaluate associations with monocular eye closure in patients with ERM, and to report binocular interference (closing 1 eye to improve visual quality). Design, Setting, and Participants: Retrospective medical record review of an adult strabismus clinic at a tertiary referral center. Patients with ERM referred from retina clinicians between June 2010 and October 2019 who completed the Adult Strabismus (AS)-20 questionnaire, including the question: "I cover or close one eye to see things better." Two groups were identified: (1) patients reporting eye closure sometimes or more, and (2) patients reporting no eye closure (as control patients). Main Outcomes and Measures: Frequencies of (1) central-peripheral rivalry (CPR)-type diplopia (dragged fovea diplopia); (2) binocular interference (monocular eye closure but no diplopia or strabismus); and (3) other, associated with monocular eye closure. Visual acuity, metamorphopsia, aniseikonia, and AS-20 quality of life domain scores (self-perception, interactions, reading function, and general function) compared between binocular interference, CPR-type diplopia, and control patients. Results: A total of 124 patients with ERM (58 of 124 were women [47%]; mean [SD] age, 70 [9] years) reported monocular eye closure. Associations were binocular interference in 36 (29%; 95% CI, 21%-38%), CPR-type diplopia in 34 (27%; 95% CI, 20%-36%), and other (primarily strabismus) in 54 (44%). Compared with control patients with ERM (n = 11), patients with ERM and binocular interference had worse quality of life on AS-20 reading function (95 vs 62; mean difference, 22 points; 95% CI, 7-27 points; P = .007) and general function (89 vs 68; mean difference, 23 points; 95% CI, 13-34 points; P = .01) domains. Compared with CPR-type diplopia, patients with binocular interference had poorer worst-eye visual acuity (median 0.50 vs 0.30 logMAR [20/63 vs 20/40]; mean difference, 0.13 logMAR; 95% CI, 0.00-0.25 logMAR [20/20 to 20/35]; P = .03), and a larger interocular difference (0.46 vs 0.19 logMAR [20/58 vs 20/30]; mean difference, 0.15 logMAR; 95% CI, 0.03-0.28 logMAR [20/21 to 20/38]; P = .004). Conclusions and Relevance: Study findings suggest that binocular interference, manifesting as monocular eye closure (without diplopia or strabismus), is a distinct entity affecting quality of life in patients with epiretinal membrane.
