RESUMO
PURPOSE: Evaluation for systemic diagnosis is an important part of pediatric cataract management. While there are reports on associated systemic and ocular associations in children with infantile cataracts, reports specifying associations in large cohorts of children undergoing cataract surgery are lacking. METHODS: Retrospective chart review of consecutive patients undergoing cataract surgery at a pediatric tertiary referral center during 30-year period was performed. Associated systemic and ocular associations were recorded. The etiologies were analyzed depending on laterality, age, and gender. RESULTS: Seven-hundred twenty-seven patients (1135 eyes) were included for analysis: 408 (56%) with bilateral and 319 (44%) with unilateral cataract. An identifiable cause for cataract was identified in 66% (270/408) bilateral and 55% (176/319) unilateral cataract patients. Hereditary cataract accounted for 22% of bilateral cataracts. An underlying syndrome or genetic diagnosis was found in 24% bilateral (97/408, 86 genetic/syndromic, 11 metabolic) but only in 2% of unilateral cases (5/319). Cataracts were the result of treatment for cancer, or other systemic conditions requiring steroids, in 60/408 bilateral (15%) and 15/319 (5%) unilateral cataract patients. In contrast, unilateral cataracts had higher ocular associations (49%, 156/319) than bilateral cataracts (6%, 23/408) primarily ocular trauma (20%, 64/319) and persistent fetal vasculature (20%, 62/319). CONCLUSION: Clinicians should be aware of potential systemic and ocular associations among children with visually significant cataracts. Those with no family history of juvenile cataract should be evaluated for systemic associations, and referral to genetics may be warranted in select cases.

PURPOSE: To compare baseline biometry measurements in eyes with pediatric cataract versus age-matched controls METHODS: This is a cross-sectional study conducted at a tertiary care hospital that included two arms-prospective arm to collect data from normal eyes and retrospective arm for eyes with pediatric cataract. In the prospective arm, biometry measurements were obtained in healthy children aged 0 to 10 years. Children under the age of four had measurements under anesthesia for an unrelated procedure, while older children had in-office measurements using optical biometry. For comparison, biometric data was collected in children with pediatric cataract through record review. One eye of each patient was randomly selected. Axial length (AL) and keratometry (K) were compared by age and laterality. The medians were compared using Wilcoxon rank-sum tests and variances using Levene's test. RESULTS: There were 100 eyes in each arm, 10 eyes in each age bin of 1-year interval. There was more variability in baseline biometry in eyes with pediatric cataract and a trend for longer AL and steeper K in cataract eyes than aged-matched controls. The difference in AL means was significant in age group 2-4 years, and variances were significant across all age groups (p=0.018). Unilateral cataracts (n=49) showed a trend toward greater variability in biometry than bilateral cataracts, but this did not reach statistical significance. CONCLUSION: Baseline biometry measures are more variable in eyes with pediatric cataract compared to age-matched controls with a trend toward longer AL and steeper K.

PURPOSE: To review the scientific literature that evaluates the effectiveness of adjustable sutures in the management of strabismus for adult and pediatric patients. METHODS: Literature searches were performed in the PubMed database through April 2021 with no date limitations and were restricted to publications in English. The searches identified 551 relevant citations, of which 55 were reviewed in full text. Of these, 17 articles met the inclusion criteria and were assigned a level of evidence rating by the panel methodologist. The search included all randomized controlled studies regardless of study size and cohort studies of 100 or more patients comparing the adjustable versus nonadjustable suture technique, with a focus on motor alignment outcomes or reoperation rates. RESULTS: The literature search yielded no level I studies. Of the 17 articles that met the inclusion criteria, 11 were rated level II and 6 were rated level III. Among the 12 studies that focused on motor alignment outcomes, 4 small randomized clinical trials (RCTs) did not find a statistically significant difference between groups, although they were powered to detect only very large differences. Seven of 8 nonrandomized studies found a statistically significant difference in motor alignment success in favor of the adjustable suture technique, both overall and in certain subgroups of patients. Successful motor alignment was seen in both exotropia (in 3 studies that were not limited to children) and esotropia (in 1 study of adults and 2 of children). The majority of included studies that reported on reoperation rates found the rates to be lower in patients who underwent strabismus surgery with adjustable sutures, but this finding was not uniformly demonstrated. CONCLUSIONS: Although there are no level I studies evaluating the effectiveness of adjustable sutures for strabismus surgery, the majority of nonrandomized studies that met the inclusion criteria for this assessment reported an advantage of the adjustable suture technique over the nonadjustable technique with respect to motor alignment outcomes. This finding was not uniformly demonstrated among all studies reviewed and warrants further investigation in the development and analysis of adjustable suture techniques.

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.

PURPOSE: This study aims to report long-term outcomes of secondary intraocular lens (IOL) implantation after early cataract surgery in children. METHODS: This is a retrospective case series that included children undergoing secondary IOL implantation. The patients had either in-the-bag (ITB) or sulcus implantation; alternative methods of IOL fixation were excluded. Single-piece acrylic IOL was used for ITB and 3-piece acrylic or PMMA IOL for sulcus implantation. The visual acuity outcomes and rate of complications at the last follow-up visit were evaluated. RESULTS: One hundred six eyes (70 patients) were analyzed. The mean follow-up was 5.5 ± 3.8 years. Sixty-two eyes (58.5%) had ITB; 44 eyes (41.5%) had sulcus IOL. All but 3 eyes (97.2%) showed stable or improvement in visual acuity. Early inflammation > grade 2 + was noted with sulcus IOL (84% vs 34%, p = 0.01); late inflammation requiring vitrectomy occurred in one eye with sulcus IOL. Mild decentration was seen in 2 eyes with sulcus IOL; one additional subluxed sulcus IOL was exchanged. Sixteen out of 106 eyes (16%) had glaucoma. Eyes that developed glaucoma had early primary surgery (mean, 0.2 years, p < 0.001, significant); there was no difference in glaucoma rates based on implantation site. CONCLUSION: Early postoperative inflammation is higher in eyes with sulcus implantation, but good visual acuity outcomes are noted after secondary IOL implantation in children. Glaucoma is the main complication that requires close monitoring and is associated with early age at primary surgery.

PURPOSE: To evaluate outcomes of bilateral cataract surgery in children aged 7 to 24 months and compare rates of adverse events (AEs) with other Toddler Aphakia and Pseudophakia Study (TAPS) registry outcomes. DESIGN: Retrospective clinical study at 10 Infant Aphakia Treatment Study (IATS) sites. Statistical analyses comparing this cohort with previously reported TAPS registry cohorts. PARTICIPANTS: Children enrolled in the TAPS registry between 2004 and 2010. METHODS: Children underwent bilateral cataract surgery with or without intraocular lens (IOL) placement at age 7 to 24 months with 5 years of postsurgical follow-up. MAIN OUTCOME MEASURES: Visual acuity (VA), occurrence of strabismus, AEs, and reoperations. RESULTS: A total of 40 children (76 eyes) who underwent bilateral cataract surgery with primary posterior capsulectomy were identified with a median age at cataract surgery of 11 months (7-23); 68% received a primary IOL. Recurrent visual axis opacification (VAO) occurred in 7.5% and was associated only with the use of an IOL (odds ratio, 6.10; P = 0.005). Glaucoma suspect (GS) was diagnosed in 2.5%, but no child developed glaucoma. In this bilateral cohort, AEs (8/40, 20%), including glaucoma or GS and VAO, and reoperations occurred in a similar proportion to that of the published unilateral TAPS cohort. When analyzed with children aged 1 to 7 months at bilateral surgery, the incidence of AEs and glaucoma or GS correlated strongly with age at surgery (P = 0.011/0.004) and glaucoma correlated with microcornea (P = 0.040) but not with IOL insertion (P = 0.15). CONCLUSIONS: Follow-up to age 5 years after bilateral cataract surgery in children aged 7 to 24 months reveals a low rate of VAO and very rare glaucoma or GS diagnosis compared with infants with cataracts operated at < 7 months of age despite primary IOL implantation in most children in the group aged 7 to 24 months. The use of an IOL increases the risk of VAO irrespective of age at surgery.

Wolfram syndrome was initially reported as an autosomal recessive (AR), progressive neurodegenerative disorder that leads to diabetes insipidus, childhood onset diabetes mellitus (DM), optic atrophy, and deafness (D) also known as DIDMOAD. However, heterozygous dominant pathogenic variants in Wolfram syndrome type 1 (WFS1) may lead to distinct, allelic conditions, described as isolated sensorineural hearing loss (SNHL), syndromic SNHL, congenital cataracts, or early onset DM. We report a family with a novel dominant, likely pathogenic variant in WFS1 (NM_006005.3) c.2605_2616del12 (p.Ser869_His872del), resulting in cataracts, SNHL, and DM in a female and her mother. A maternal aunt had cataracts, DM, and SNHL but was not tested for the familial WFS1 mutation. Both the mother and maternal aunt had early menopause by age 43 years and infertility which may be a coincidental finding that has not been associated with autosomal dominant AD WFS1-related disorder to the best of our knowledge. Screening at risk individuals in families with the AR Wolfram syndrome, for DM, SNHL, and for cataracts is indicated.

PURPOSE: To review the published literature assessing the efficacy of binocular therapy for the treatment of amblyopia compared with standard treatments. METHODS: Literature searches with no date restrictions and limited to the English language were conducted in January 2018 and updated in April 2019 in the PubMed database and the Cochrane Library database with no restrictions. The search yielded 286 citations, and the full text of 50 articles was reviewed. Twenty articles met the inclusion criteria for this assessment and were assigned a level of evidence rating by the panel methodologist. Six studies were rated level I, 1 study was rated level II, and 13 studies were rated level III because of the impact on the development and popularization of this technology. RESULTS: Two of the level I and II studies reviewed described a significant improvement in visual acuity in the binocular group versus standard patching standard treatment (the total number of patients in these 2 studies was 147). However, the 5 studies that failed to show a visual improvement from binocular therapy compared with standard treatments were larger and more rigorously designed (the total number of patients in these 5 studies was 813). Level I and II studies also failed to show a significant improvement over baseline in sensory status, including depth of suppression and stereopsis of those treated with binocular therapy. Several smaller level III case series (total number of patients in these 13 studies was 163) revealed more promising results than the binocular treatments studied in the level I and II studies, especially using treatments that are more engaging and are associated with better compliance. CONCLUSIONS: There is no level I evidence to support the use of binocular treatment as a substitute for current therapies for amblyopia (including patching and optical treatment). Furthermore, 2 large randomized controlled trials showed inferior performance compared with standard patching treatment. On the basis of this review of the published literature, binocular therapy cannot be recommended as a replacement for standard amblyopia therapy. However, more research is needed to determine the potential benefits of proposed binocular treatments in the future.

PURPOSE: The purpose of this assessment is to evaluate the accuracy of autorefraction compared with cycloplegic retinoscopy in children. METHODS: Literature searches were last conducted in October 2019 in the PubMed and the Cochrane Library databases for studies published in English. The combined searches yielded 118 citations, of which 53 were reviewed in full text. Of these, 31 articles were deemed appropriate for inclusion in this assessment and subsequently assigned a level of evidence rating by the panel methodologists. Four articles were rated level I, 11 were rated level II, and 16 were rated level III articles. The 16 level III articles were excluded from this review. RESULTS: Thirteen of the 15 studies comparing cycloplegic autorefraction with cycloplegic retinoscopy found a mean difference in spherical equivalent or sphere of less than 0.5 diopters (D); most were less than 0.25 D. Even lower mean differences were found when evaluating the cylindrical component of cycloplegic autorefraction versus cycloplegic retinoscopy. Despite low mean variability, there was significant individual measurement variability; the 95% limits of agreement were wide and included clinically relevant differences. Comparisons of noncycloplegic with cycloplegic autorefractions found that noncyloplegic refraction tends to over minus by 1 to 2 D. CONCLUSIONS: Cycloplegic autorefraction is appropriate to use in pediatric population-based studies. Cycloplegic retinoscopy can be valuable in individual clinical cases to confirm the accuracy of cycloplegic autorefraction, particularly when corrected visual acuity is worse than expected or the autorefraction results are not consistent with expected findings.

PURPOSE: To evaluate outcomes of bilateral cataract surgery in infants 1 to 7 months of age performed by Infant Aphakia Treatment Study (IATS) investigators during IATS recruitment and to compare them with IATS unilateral outcomes. DESIGN: Retrospective case series review at 10 IATS sites. PARTICIPANTS: The Toddler Aphakia and Pseudophakia Study (TAPS) is a registry of children treated by surgeons who participated in the IATS. METHODS: Children underwent bilateral cataract surgery with or without intraocular lens (IOL) placement during IATS enrollment years 2004 through 2010. MAIN OUTCOME MEASURES: Visual acuity (VA), strabismus, adverse events (AEs), and reoperations. RESULTS: One hundred seventy-eight eyes (96 children) were identified with a median age of 2.5 months (range, 1-7 months) at the time of cataract surgery. Forty-two eyes (24%) received primary IOL implantation. Median VA of the better-seeing eye at final study visit closest to 5 years of age with optotype VA testing was 0.35 logarithm of the minimum angle of resolution (logMAR; optotype equivalent, 20/45; range, 0.00-1.18 logMAR) in both aphakic and pseudophakic children. Corrected VA was excellent (<20/40) in 29% of better-seeing eyes, 15% of worse-seeing eyes. One percent showed poor acuity (≥20/200) in the better-seeing eye, 12% in the worse-seeing eye. Younger age at surgery and smaller (<9.5 mm) corneal diameter at surgery conferred an increased risk for glaucoma or glaucoma suspect designation (younger age: odds ratio [OR], 1.44; P = 0.037; and smaller cornea: OR, 3.95; P = 0.045). Adverse events also were associated with these 2 variables on multivariate analysis (younger age: OR, 1.36; P = 0.023; and smaller cornea: OR, 4.78; P = 0.057). Visual axis opacification was more common in pseudophakic (32%) than aphakic (8%) eyes (P = 0.009). Unplanned intraocular reoperation occurred in 28% of first enrolled eyes (including glaucoma surgery in 10%). CONCLUSIONS: Visual acuity after bilateral cataract surgery in infants younger than 7 months is good, despite frequent systemic and ocular comorbidities. Although aphakia management did not affect VA outcome or AE incidence, IOL placement increased the risk of visual axis opacification. Adverse events and glaucoma correlated with a younger age at surgery and glaucoma correlated with the presence of microcornea.

PURPOSE: To review the published evidence to evaluate the ability of orthokeratology (Ortho-K) treatment to reduce myopic progression in children and adolescents compared with the use of spectacles or daytime contact lenses for standard refractive correction. METHODS: Literature searches of the PubMed database, the Cochrane Library, and the databases of clinical trials were last conducted on August 21, 2018, with no date restrictions but limited to articles published in English. These searches yielded 162 citations, of which 13 were deemed clinically relevant for full-text review and inclusion in this assessment. The panel methodologist then assigned a level of evidence rating to the selected studies. RESULTS: The 13 articles selected for inclusion include 3 prospective, randomized clinical trials; 7 nonrandomized, prospective comparative studies; and 3 retrospective case series. One study provided level I evidence, 11 studies provided level II evidence, and 1 study provided level III evidence. Most studies were performed in populations of Asian ethnicity. Change in axial length was the primary outcome for 10 of 13 studies and change in refraction was the primary outcome for 3 of 13 studies. In these studies, Ortho-K typically reduced axial elongation by approximately 50% over a 2-year study period. This corresponds to average axial length change values of approximately 0.3 mm for Ortho-K patients compared with 0.6 mm for control patients, which corresponds to a typical difference in refraction of approximately 0.5 diopters (D). Younger age groups and individuals with larger than average pupil size may have a greater effect with Ortho-K. Rebound can occur after discontinuation or change to alternative refractive treatment. CONCLUSIONS: Orthokeratology may be effective in slowing myopic progression for children and adolescents, with a potentially greater effect when initiated at an early age (6-8 years). Safety remains a concern because of the risk of potentially blinding microbial keratitis from contact lens wear.

PURPOSE: To review the published literature assessing the efficacy of ß-blockers for the treatment of periocular hemangioma in infants. METHODS: Literature searches were conducted in May 2018 in PubMed with no date restrictions and limited to studies published in English and in the Cochrane Library database without any restrictions. The combined searches yielded 437 citations. Of these,16 articles were deemed appropriate for inclusion in this assessment and assigned a level of evidence rating by the panel methodologist. RESULTS: None of the 16 studies included in this assessment were rated level I, 3 were rated level II, and 13 were rated level III. The most common treatment regimen was 2 mg/kg daily oral propranolol, but intralesional and topical ß-blockers were also used. Treatment effect was most often measured in terms of reduction in the size of the lesions, which occurred in the majority of patients. ß-Blockers were consistently shown to reduce astigmatism, but this reduction was shown to be statistically significant in only 2 series. The effect of ß-blockers on amblyopia was not adequately documented. ß-Blockers were generally well tolerated and had mild side effects (fatigue, gastrointestinal upset/diarrhea, restlessness/sleep disturbances, minor wheezing, and cold extremities). Complications severe enough to require cessation of treatment occurred in only 2 patients out of a total of 229 who received ß-blockers. CONCLUSIONS: There is limited evidence to support the safety and efficacy of both topical and systemic ß-blockers to promote regression of periocular hemangiomas. Additional research may confirm the best dosage and route of administration to maximize efficacy in reducing induced astigmatism and amblyopia associated with periocular hemangiomas while minimizing side effects.

PURPOSE: To compare the visual outcomes and adverse events associated with optical correction using an intraocular lens (IOL), contact lenses, or spectacles after cataract surgery in children 2 years of age or younger. METHODS: Literature searches were conducted in PubMed, the Cochrane Library, and the databases of clinical trials in February 2019, without date or language restrictions. The search resulted in 194 potentially relevant citations, and 34 were selected for full-text review. Fourteen studies were determined to be relevant to the assessment criteria and were selected for inclusion in this assessment. The panel methodologist then assigned a level of evidence rating to these studies. RESULTS: Intraocular lenses were associated with visual outcomes similar to outcomes for contact lenses or spectacles for children who had both bilateral and unilateral cataracts. Intraocular lenses were also associated with an increased risk of visual axis opacities. All treatments were associated with a similar incidence of glaucoma. Although ocular growth was similar for all treatments, infants younger than 6 months who underwent IOL implantation had large myopic shifts that often resulted in high myopia or severe anisometropia later in childhood. Corneal endothelial cell counts were lower in eyes that underwent IOL implantation. The incidence of strabismus was similar with all treatments. CONCLUSIONS: Intraocular lens implantation is not recommended for children 6 months of age or younger because there is a higher incidence of visual axis opacities with this treatment compared with aphakia. The best available evidence suggests that IOL implantation can be done safely with acceptable side effects in children older than 6 months of age. However, the unpredictability of ocular growth means that these children will often have large refractive errors later in childhood that may necessitate an IOL exchange or wearing spectacles or contact lenses with a large refractive correction. In addition, the training and experience of the surgeon as well as ocular and systemic comorbidities should be taken into consideration when deciding whether IOL implantation would be appropriate.

PURPOSE: To evaluate outcomes of unilateral cataract surgery in children 7 to 24 months of age. DESIGN: Retrospective case series at 10 Infant Aphakia Treatment Study (IATS) sites. PARTICIPANTS: The Toddler Aphakia and Pseudophakia Study is a registry of children treated by surgeons who participated in the IATS. METHODS: Children underwent unilateral cataract surgery with or without intraocular lens (IOL) placement during the IATS enrollment years of 2004 and 2010. MAIN OUTCOME MEASURES: Intraoperative complications, adverse events (AEs), visual acuity, and strabismus. RESULTS: Fifty-six children were included with a mean postoperative follow-up of 47.6 months. Median age at cataract surgery was 13.9 months (range, 7.2-22.9). Ninety-two percent received a primary IOL. Intraoperative complications occurred in 4 patients (7%). At 5 years of age, visual acuity of treated eyes was very good (≥20/40) in 11% and poor (≤20/200) in 44%. Adverse events were identified in 24%, with a 4% incidence of glaucoma suspect. An additional unplanned intraocular surgery occurred in 14% of children. Neither AEs nor intraocular reoperations were more common for children with surgery at 7 to 12 months of age than for those who underwent surgery at 13 to 24 months of age (AE rate, 21% vs. 25% [P = 0.60]; reoperation rate, 13% vs. 16% [P = 1.00]). CONCLUSIONS: Although most children underwent IOL implantation concurrent with unilateral cataract removal, the incidence of complications, reoperations, and glaucoma was low when surgery was performed between 7 and 24 months of age and compared favorably with same-site IATS data for infants undergoing surgery before 7 months of age. Our study showed that IOL implantation is relatively safe in children older than 6 months and younger than 2 years.

OBJECTIVE: To evaluate to what extent indicators of placenta insufficiency are associated with low concentrations of insulin-like growth factor 1 (IGF-1) and IGF-1-binding protein-1 (IGFBP-1) in neonatal blood, and to what extent the concentrations of these growth factors are associated with concentrations of proteins with inflammatory, neurotrophic, or angiogenic properties. STUDY DESIGN: Using multiplex immunoassays, we measured the concentrations of IGF-1 and IGFBP-1, as well as 25 other proteins in blood spots collected weekly from ≥ 880 infants born before the 28th week of gestation, and sought correlates of concentrations in the top and bottom quartiles for gestational age and day the specimen was collected. RESULTS: Medically indicated delivery and severe fetal growth restriction (sFGR) were associated with low concentrations of IGF-1 on the first postnatal day and with high concentrations of IGFBP-1 on almost all days. Elevated concentrations of IGF-1 and IGFBP-1 were accompanied by elevated concentrations of many other proteins with inflammatory, neurotrophic, or angiogenic properties. CONCLUSION: Disorders associated with impaired placenta implantation and sFGR appear to account for a relative paucity of IGF-1 on the first postnatal day. Elevated concentrations of IGF-1 and especially IGFBP-1 were associated with same-day elevated concentrations of inflammatory, neurotrophic, and angiogenic proteins.

PURPOSE: To review the published literature to assess the visual outcomes and adverse events associated with the 2 most commonly used contact lenses for treating aphakia in children: silicone elastomer (SE) and rigid gas permeable (RGP). METHODS: Literature searches were last conducted in January 2018 in the PubMed, Cochrane Library, and ClinicalTrials.gov databases with no date or language restrictions. These combined searches yielded 167 citations, 27 of which were reviewed in full text. Of these, 10 articles were deemed appropriate for inclusion in this assessment and subsequently assigned a level of evidence rating by the panel methodologist. RESULTS: The literature search identified 4 level II studies and 6 level III studies. There were insufficient data to compare visual outcomes for eyes treated using SE lenses versus RGP lenses. Silicone elastomer lenses have the advantage that they can be worn on an extended-wear basis, but they were associated with more adverse events than RGP lenses. These adverse events included microbial keratitis, corneal infiltrates, corneal edema, corneal scars, lenses adhering to the cornea, superficial punctate keratopathy, lid swelling, and conjunctival hyperemia. The lens replacement rate was approximately 50% higher for RGP lenses in the only study that directly compared SE and RGP lenses. CONCLUSIONS: Limited evidence was found in the literature on this topic. Silicone elastomer and RGP contact lenses were found to be effective for treating aphakia in children. Silicone elastomer lenses are easier to fit and may be worn on an extended-wear basis. Rigid gas permeable lenses must be removed every night and require a more customized fit, but they are associated with fewer adverse events. The choice of which lens a practitioner prescribes should be based on the particular needs of each patient.

OBJECTIVES: Surveys are an important tool to assess the impact of research on physicians' approach to patient care. This survey was conducted to assess current practice patterns in the management of infantile cataracts in light of the findings of the Infant Aphakia Treatment Study. METHODS: Pediatric ophthalmologists were emailed a link to the survey using newsletters from American Association of Pediatric Ophthalmology and Strabismus, World Society of Pediatric Ophthalmology and Strabismus, and the Pediatric Listserv. The 17-question survey was anonymous and active during July to August 2016. RESULTS: One hundred twenty-five respondents (North America, 65%; Asia, 12%; Europe, 9%; and other, 14%) reported operating on pediatric cataracts. Most practice in a university setting (55%). There was a strong consensus that unilateral cataract surgery should be performed between ages 4 to 6 weeks and aphakic contact lenses should be used to optically correct their eyes, particularly in children ≤6 months of age. For bilateral cataracts, there was a trend for surgeons to perform cataract surgery at an older age than unilateral cataract surgery. Surgeons who performed less than 5 versus greater than 20 pediatric cataract surgeries/year were more likely to use aphakic contact lenses in children undergoing cataract surgery more than 6 months of age (62% vs. 35%, P=0.04). Most respondents (73%) indicated that the Infant Aphakia Treatment Study had changed how they manage unilateral congenital cataracts. CONCLUSION: Most pediatric cataract surgeons perform congenital cataract surgery between ages 4 to 6 weeks and use aphakic contact lenses for initial optical correction in infants less than 6 months. Surgeons have equal preference for intraocular lenses and contact lenses in infants more than 6 months of age.

PURPOSE: To review the available evidence on the ocular safety and efficacy of anti-vascular endothelial growth factor (VEGF) agents for the treatment of retinopathy of prematurity (ROP) compared with laser photocoagulation therapy. METHODS: A literature search of the PubMed and Cochrane Library databases was conducted last on September 6, 2016, with no date restrictions and limited to articles published in English. This search yielded 311 citations, of which 37 were deemed clinically relevant for full-text review. Thirteen of these were selected for inclusion in this assessment. The panel methodologist assigned ratings to the selected articles according to the level of evidence. RESULTS: Of the 13 citations, 6 articles on 5 randomized clinical trials provided level II evidence supporting the use of anti-VEGF agents, either as monotherapy or in combination with laser therapy. The primary outcome for these articles included recurrence of ROP and the need for retreatment (3 articles), retinal structure (2 articles), and refractive outcome (1 article). Seven articles were comparative case series that provided level III evidence. The primary outcomes included the effects of anti-VEGF treatment on development of peripheral retinal vessels (1 article), refractive outcomes (1 article), or both structural and refractive or visual outcomes (5 articles). CONCLUSIONS: Current level II and III evidence indicates that intravitreal anti-VEGF therapy is as effective as laser photocoagulation for achieving regression of acute ROP. Although there are distinct ocular advantages to anti-VEGF pharmacotherapy for some cases (such as eyes with zone I disease or aggressive posterior ROP), the disadvantages are that the ROP recurrence rate is higher, and vigilant and extended follow-up is needed because retinal vascularization is usually incomplete. After intravitreal injection, bevacizumab can be detected in serum within 1 day, and serum VEGF levels are suppressed for at least 8 to 12 weeks. The effects of lowering systemic VEGF levels on the developing organ systems of premature infants are unknown, and there are limited long-term data on potential systemic and neurodevelopmental effects after anti-VEGF use for ROP treatment. Anti-VEGF agents should be used judiciously and with awareness of the known and unknown or potential side effects.
