Importance Amblyopia is the leading cause of monocular decreased best-corrected vision in children. Early detection and intervention are key for optimal treatment outcomes; however, limited access to pediatric eye specialists may hinder timely care and affect visual outcomes. Given the shortage of specialty-trained eye care professionals in the US, there is need to support comprehensive eye care professionals who are willing to examine and treat children with amblyopia. Objective A panel from the Pediatric Eye Disease Investigator Group synthesized relevant literature and incorporated consensus opinion where direct evidence was lacking to create the Amblyopia Navigator Decision-Support Instrument, a free, web-based amblyopia decision support tool for eye care professionals. Evidence Review The decisions related to optimal diagnostic measures, pass/refer criteria, and management recommendations were informed by 147 publications. In areas where direct evidence was lacking, guidance was supplemented with clinical trial protocols or existing professional guidelines. When data were conflicting or unavailable, recommendations were established through committee consensus. A single reviewer independently performed standardized (though not systematic) literature reviews to avoid missing pertinent recent publications. Findings Presented are the process used, supporting evidence, and recommendations for testing methods, refractive correction, amblyopia treatment options, treatment adjustments, and monitoring schedules. Conclusions and Relevance Because amblyopia is common and typically responds well to treatment, decision support tools that optimize its management could increase access to pediatric eye care by facilitating earlier detection, enabling broader participation of primary eye care professionals, and ultimately improving visual outcomes. Through this work and the development of the forthcoming free, web-based application version, Amblyopia Navigator Decision-Support Instrument, the Pediatric Eye Disease Investigator Group has created decision support tools designed to assist optometrists and ophthalmologists in the care of children aged 3 to 17 years with amblyopia.

ABSTRACT Purpose To validate a custom smartphone application for at‐home visual acuity (VA) measurement in children. Methods A total of 452 children aged 3–17.5 years participated. Certified examiners measured in‐office test–retest VA (logMAR) using gold‐standard Amblyopia Treatment Study HOTV (3‐to‐6‐year‐olds, younger cohort) or electronic Early Treatment of Diabetic Retinopathy Study (7‐to‐17.5‐year‐olds, older cohort) protocols at 3–4.5 m and app‐based VA at 1.5 m. Caregivers measured at‐home app‐based VA at 1.5 m. Results Comparing at‐home app‐based with gold‐standard VA, in eyes 20/40 or better, 95% (143/151) and 93% (91/98) of the younger and older cohorts were within 2 lines, respectively (mean differences: younger = −0.03, older = −0.04; 95% limits‐of‐agreement half‐width (LOA): younger = ±0.26, older = ±0.22). In eyes 20/50 or worse, 66% (42/64) and 75% (76/101) of the younger and older cohorts were within 2 lines, respectively (mean differences: younger = 0.11, older = 0.13, LOA: younger = ±0.50, older = ±0.51). Comparing in‐office app‐based VA with gold‐standard VA, in eyes 20/40 or better, 98% (160/164) and 94% (99/105) of the younger and older cohorts were within 2 lines, respectively (mean differences: younger = −0.03, older = −0.03; LOA: younger = ±0.22; older = ±0.24). In eyes 20/50 or worse, 85% (60/71) and 91% (101/111) of the younger and older cohorts were within 2 lines, respectively (mean differences: younger = 0.04; older = 0.04; LOA: younger = ±0.39; older = ±0.24). For gold‐standard test–retest, in eyes 20/40 or better, 99% (163/164) and 99% (104/105) of the younger and older cohorts had retest within 2 lines, respectively (mean differences: younger = 0.00; older = 0.01; LOA: younger = ±0.17; older = ±0.11). For 20/50 or worse, 92% (66/72) and 100% (111/111) in the younger and older cohorts were within 2 lines, respectively (mean differences: younger = 0.01; older = 0.02; LOA: younger = ±0.35; older = ±0.15). Conclusions Our app demonstrated good concordance with the gold standard at home and in the office for eyes with VA of 20/40 or better. However, concordance decreased considerably for eyes with VA 20/50 or worse, particularly at home.

Importance The long-term outcomes of surgery for pediatric traumatic cataract are not well described; understanding these outcomes would inform parental expectations. Objective To report visual acuity (VA) outcomes and cumulative incidence of ocular complications by 5 years following lensectomy for pediatric traumatic cataract. Design, Setting, and Participants This prospective cohort study was conducted across 32 sites in the US and Canada among 75 children undergoing lensectomy from birth to less than 13 years of age for unilateral traumatic cataract. Of 75 children, 60 had primary intraocular lens (IOL) placement; 15 were left aphakic. Data were collected from August 2012 to February 2020. Data analysis was performed from October 2022 to May 2025. Exposure Lensectomy. Main Outcomes and Measures The primary outcomes were best-corrected VA 5 years after lensectomy; period prevalence of strabismus and glaucoma (including cases diagnosed before lensectomy); surgery for visual axis opacification (VAO); and cumulative incidence of ocular complications by 5 years. Annual data collection was from medical record reviews through 5 years following lensectomy. Results Among 75 participants, 28 (37%) were female, and median (range) age at lensectomy was 7.4 years (0.1-13 years). Median (IQR) best-corrected VA at 5 years (available for 37 participants [49%]) was 20/63 (20/35-20/159) in pseudophakic eyes (n = 29; mean [SD] age at surgery, 7.2 [3.0] years) and 20/258 (20/56-<20/800) in aphakic eyes (n = 8; mean [SD] age at surgery, 5.5 [4.3] years). Age-normal VA was achieved by 6 pseudophakic eyes (21%; 95% CI, 10%-38%) and 1 aphakic eye (13%; 95% CI, 2%-47%). The 5-year period prevalence of glaucoma was 9% in pseudophakic eyes (95% CI, 1%-16%) and 9% in aphakic eyes (95% CI, 0%-24%). The 5-year cumulative incidence of surgery for VAO was 47% in pseudophakic eyes (95% CI, 31%-60%) and 13% in aphakic eyes (95% CI, 0%-28%). The risk was greater in eyes that did not undergo an anterior vitrectomy (84%; 95% CI, 55%-94%) vs eyes that did (15%; 95% CI, 2%-26%) (age-adjusted hazard ratio, 11.4; 95% CI, 4.6-33.1; P < .001). Conclusions and Relevance In this cohort study, while only half of the study participants had a 5-year follow-up visit, achieving age-normal VA was uncommon among the cohort in whom a best-corrected VA was determined. The prevalence of glaucoma at 5 years was low among those with 5-year follow-up, while nearly half of the pseudophakic eyes needed surgery for VAO supporting the need to monitor these children.

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.

ImportanceGlaucoma can develop following cataract removal in children.ObjectiveTo 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 ParticipantsThis 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.ExposuresUsual clinical care after lensectomy.Main Outcomes and MeasuresThe main outcomes were cumulative incidence of glaucoma-related adverse events and baseline factors associated with risk of these adverse events.ResultsThe 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 RelevanceIn 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.
