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.Masked, multicenter, dose de-escalation study.One hundred twenty prematurely born infants with type 1 ROP.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.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.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.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.

SIGNIFICANCE Binocular treatment for unilateral amblyopia is an emerging treatment that requires evaluation through a randomized clinical trial. PURPOSE This study aimed to compare change in amblyopic-eye visual acuity (VA) in children aged 4 to 6 years treated with the dichoptic binocular iPad (Apple, Cupertino, CA) game, Dig Rush (not yet commercially available; Ubisoft, Montreal, Canada), plus continued spectacle correction versus continued spectacle correction alone. METHODS Children (mean age, 5.7 years) were randomly assigned to home treatment for 8 weeks with the iPad game (prescribed 1 h/d, 5 d/wk [n = 92], or continued spectacle correction alone [n = 90]) in a multicenter randomized clinical trial. Before enrollment, children wearing spectacles were required to have at least 16 weeks of wear or no improvement in amblyopic-eye VA (<0.1 logMAR) for at least 8 weeks. Outcome was change in amblyopic-eye VA from baseline to 4 weeks (primary) and 8 weeks (secondary) assessed by masked examiner. RESULTS A total of 182 children with anisometropic (63%), strabismic (16%; <5∆ near, simultaneous prism and cover test), or combined-mechanism (20%) amblyopia (20/40 to 20/200; mean, 20/63) were enrolled. After 4 weeks, mean amblyopic VA improved by 1.1 logMAR lines with binocular treatment and 0.6 logMAR lines with spectacles alone (adjusted difference, 0.5 lines; 95.1% confidence interval [CI], 0.1 to 0.9). After 8 weeks, results (binocular treatment: mean amblyopic-eye VA improvement, 1.3 vs. 1.0 logMAR lines with spectacles alone; adjusted difference, 0.3 lines; 98.4% CI, −0.2 to 0.8 lines) were inconclusive because the CI included both zero and the pre-defined difference in mean VA change of 0.75 logMAR lines. CONCLUSIONS In 4- to 6-year-old children with amblyopia, binocular Dig Rush treatment resulted in greater improvement in amblyopic-eye VA for 4 weeks but not 8 weeks. Future work is required to determine if modifications to the contrast increment algorithm or other aspects of the game or its implementation could enhance the treatment effect.

Importance:Cataract is an important cause of visual impairment in children. Outcomes reported from a large clinical disease-specific registry can provide real-world estimates of visual outcomes and rates of adverse events in clinical practice.Objective:To describe visual acuity and refractive error outcomes, as well as rates of amblyopia, glaucoma, and additional eye surgery, during the first year after lensectomy in children.Design, Setting, and Participants:A prospective observational study was conducted from June 18, 2012, to July 8, 2015, at 61 pediatric eye care practices among 880 children younger than 13 years at the time of lensectomy in at least 1 eye with follow-up within 15 months after surgery. Statistical analysis was performed from December 12, 2016, to December 14, 2018.Exposures:Lensectomy with or without implantation of an intraocular lens.Main Outcomes and Measures:Visual acuity as well as rates of amblyopia, glaucoma, suspected glaucoma, and other intraocular surgery.Results:Among the 880 children (432 girls and 448 boys; mean [SD] age at annual follow-up, 4.9 [3.8] years) in the study, lens surgery was bilateral in 362 (41.1%; 95% CI, 37.9%-44.4%) children and unilateral in 518 (58.9%; 95% CI, 55.6%-62.1%). An intraocular lens was implanted in 654 of 1132 eyes (60.2%; 95% CI, 57.0%-63.4% [proportions reported for eye-level outcomes account for the potential correlation induced by enrolling both eyes of some individuals; for participants who received bilateral surgery, these numbers will differ from the quotient of the number of cases divided by the total sample size]). Amblyopia was identified in 449 children (51.0%; 95% CI, 47.7%-54.3%). In children age 3 years or older, mean visual acuity was 0.30 logMAR (about 20/40) in 153 bilateral pseudophakic eyes, 0.49 logMAR (about 20/63) in 141 unilateral pseudophakic eyes, 0.47 logMAR (about 20/63) in 21 bilateral aphakic eyes, and 0.61 logMAR (about 20/80) in 17 unilateral aphakic eyes. Mean visual acuity improved with older age at surgery in eyes with bilateral pseudophakia by 0.2 logMAR line (99% CI, 0.02-0.4; P = .005) and by 0.3 logMAR line (99% CI, 0.04-0.60; P = .004) in eyes with unilateral pseudophakia. A new diagnosis of glaucoma or suspected glaucoma was made in 67 of 1064 eyes that did not have glaucoma prior to lensectomy (5.9%; 95% CI, 4.6%-7.7%); 36 of 273 eyes with bilateral aphakia (13.2%; 95% CI, 9.0%-19.0%), 5 of 308 eyes with bilateral pseudophakia (1.5%; 95% CI, 0.6%-4.2%), 14 of 178 eyes with unilateral aphakia (7.9%; 95% CI, 4.7%-12.8%), and 12 of 305 eyes with unilateral pseudophakia (3.9%; 95% CI, 2.2%-6.8%). Additional intraocular surgery, most commonly vitrectomy or membranectomy to clear the visual axis, was performed in 189 of 1132 eyes (17.0%; 95% CI, 14.8%-19.6%).Conclusions and Relevance:Amblyopia was frequently observed during the first year after lensectomy in this cohort of children younger than 13 years. For children age 2 years or older at surgery visual acuity was typically less than normal for age and was worse with unilateral cataract. Management of visual axis obscuration was the most common complication requiring surgical intervention during the first year after surgery.

PURPOSE:To compare visual acuity (VA) and binocularity outcomes in moderately hyperopic children with normal VA and binocularity assigned to glasses versus observation. DESIGN:Prospective randomized clinical trial (RCT). METHODS:One hundred nineteen 3- to 5-year-old children with hyperopia between +3.00D and +6.00D spherical equivalent were randomly assigned to glasses versus observation (with glasses prescribed if deteriorated for subnormal distance VA or near stereoacuity, or manifest strabismus). Follow-up occurred every 6 months. At 3 years, the treatment strategy was classified as "failed" if any of the following were met, both with and without correction: subnormal distance VA or stereoacuity; manifest strabismus; or strabismus surgery during follow-up. RESULTS:Of 84 (71%) children who completed the primary outcome examination, failure occurred in five (12%; 95% confidence interval [CI]: 4%-26%) of 41 assigned to glasses and four (9%; 95% CI: 3%-22%) of 43 assigned to observation (difference = 3%; 95% CI: -12%-18%; P = .72). Deterioration prior to 3 years (requiring glasses per protocol) occurred in 29% (95% CI: 19%-43%) assigned to glasses and 27% (95% CI: 17%-42%) assigned to observation. CONCLUSIONS:In an RCT comparing glasses to observation for moderately hyperopic 3- to 5-year-old children with normal VA and binocularity, failure for VA or binocularity was not common. With insufficient enrollment and retention, our study was unable to determine whether immediate glasses prescription reduces failure rate, but low failure rates suggest that immediate glasses prescription for these children may not be needed to prevent failure for VA and/or binocularity.

PURPOSE:To compare efficacy and safety of EX-PRESS mini glaucoma shunt (Alcon) and trabeculectomy with mitomycin-C (MMC) in the management of pediatric glaucoma.METHODS:The authors retrospectively reviewed patients from a single pediatric ophthalmology practice with either congenital or juvenile glaucoma who underwent surgical treatment with either trabeculectomy or EX-PRESS shunt insertion with MMC. Postoperative intraocular pressure at 6, 18, and 36 months, medication requirements, visual acuities, postoperative interventions, complications, and noncompliance with medications or follow-up was reviewed.RESULTS:A total of 42 cases of glaucoma with either trabeculectomy or EX-PRESS shunt were identified for review (n trabeculectomy=25, n EX-PRESS=17). At 6 months, 62.5% of trabeculectomies and 94.1% of EX-PRESS shunts met criteria for success (P=0.0281). At 18 months, 38.1% of trabeculectomies and 81.3% of EX-PRESS shunts met criteria for success (P=0.0178). At 36 months, trabeculectomies had a success rate of 33.3% versus 66.7% for EX-PRESS shunts (P=0.321). The average decrease in medications postoperatively was 0.375 and 1.63 for trabeculectomy and EX-PRESS shunt, respectively (P=0.06). Preoperative visual acuities compared with postoperative best-corrected visual acuities before additional surgery demonstrated a slight average worsening of 0.11 logMAR in trabeculectomy patients and an average improvement of 0.56 logMAR in EX-PRESS shunt patients (P=0.0037).CONCLUSIONS:In this review, patients with pediatric glaucoma managed with EX-PRESS shunt with MMC compared with trabeculectomy with MMC appear to have better intraocular pressure control, better visual acuities, and fewer complications and reoperations.

Purpose: To compare long-term outcomes after bilateral lateral rectus recession (BLRc) or unilateral lateral rectus recession combined with medial rectus resection in the same eye (R&R) for primary treatment of childhood intermittent exotropia (IXT). Design: Multicenter, randomized clinical trial. Participants: One hundred ninety-seven children 3 to younger than 11 years of age with basictype IXT, a largest deviation by prism and alternate cover test at any distance of 15 to 40 prism diopters (PD), and near stereoacuity of at least 400 seconds of arc. Methods: Random assignment to BLRc or R&R and masked examinations conducted every 6 months after surgery for 3 years. Main Outcome Measures: Proportion of participants meeting suboptimal surgical outcome by 3 years, defined as: (1) exotropia of 10 PD or more at distance or near using simultaneous prism and cover test (SPCT); or (2) constant esotropia of 6 PD or more at distance or near using SPCT; (3) loss of 2 octaves or more of stereoacuity from baseline, at any masked examination; or (4) reoperation without meeting any of these criteria. Results: Cumulative probability of suboptimal surgical outcome by 3 years was 46% (43/101) in the BLRc group versus 37% (33/96) in the R&R group (treatment group difference of BLRc minus R&R, 9%; 95% confidence interval [CI], 6% to 23%). Reoperation by 3 years occurred in 9 participants (10%) in the BLRc group (8 of 9 met suboptimal surgical outcome criteria) and in 4 participants (5%) in the R&R group (3 of 4 met suboptimal surgical outcome criteria; treatment group difference of BLRc minus R&R, 5%; 95% CI, 2% to 13%). Among participants completing the 3year visit, 29% (25 of 86) in the BLRc group and 17% (13 of 77) in the R&R group underwent reoperation or met suboptimal surgical outcome criteria at 3 years (treatment group difference of BLRc minus R&R, 12%; 95% CI, 1% to 25%). Conclusions: We did not find a statistically significant difference in suboptimal surgical outcome by 3 years between children with IXT treated with BLRc compared with those treated with R&R. Based on these findings, we are unable to recommend one surgical approach over the other for childhood IXT. (C) 2018 by the American Academy of Ophthalmology

OBJECTIVE:To determine how often nasolacrimal duct obstruction (NLDO) resolves with 6 months of nonsurgical management in infants aged 6 to less than 10 months.METHODS:As part of a randomized trial evaluating the cost-effectiveness of immediate office probing vs observation with deferred probing for unresolved cases, 107 infants aged 6 to less than 10 months who had NLDO and no history of nasolacrimal duct surgery were prescribed 6 months of nasolacrimal duct massage and topical antibiotics as needed. Resolution of the NLDO was assessed 6 months after study entry and was defined as the absence of all clinical signs of NLDO (epiphora, increased tear lake, or mucous discharge) and not having undergone NLDO surgery. Exploratory analyses assessed whether baseline characteristics, including age, sex, laterality, and prior treatment, were associated with the probability of NLDO resolving without surgery.RESULTS:At the 6-month examination, which was completed for 117 of the 133 eyes (88%), the NLDO had resolved without surgery in 77 eyes (66% [95% CI, 56%-74%]). None of the baseline characteristics we evaluated were found to be associated with resolution.CONCLUSIONS:In infants 6 to less than 10 months of age, more than half of eyes with NLDO will resolve within 6 months with nonsurgical management. Knowledge of the rate of NLDO resolution in infancy without surgery will help clinicians and parents effectively discuss treatment options.

Purpose. After corneal injury, persistent epithelial defects (PED's) may occur due to the chronic failure of the regenerating epithelium to adhere to the underlying stroma. The aim of this study was to examine the potential of epsilon-aminocaproic acid (EACA) as a topical treatment for PED's. EACA inhibits the activation of plasmin, which metabolizes fibronectin. Fibronectin, a glycoprotein, anchors corneal epithelium to the basement membrane and the underlying stroma. Methods. In anesthetized rabbits, PED's were induced with sodium hydroxide (1 N). Seven days later, during the late healing phase, treatment began with administration of EACA (30%) to the right eye and administration of vehicle alone to the left eye three times daily. A control group received neither EACA nor vehicle. Rabbits were treated for 19 days. PED's were visualized by fluorescein staining. Their size was mapped using digital planimetry. Results. After 11 days of treatment with EACA, treated PED's were 50% smaller than in corneas treated with vehicle alone. Following treatment for 15 days, corneas treated with EACA had significantly greater re-epithelialization than vehicle-treated or control corneas. Frozen sections stained immunofluorescently for fibronectin appeared to qualitatively contain more adherent fibronectin in treated corneas. Transmission and scanning electron microscopy indicated that the epithelium was more polymorphic, thinner and vacuolated in untreated controls compared to EACA treated eyes. Light microscopy demonstrated more continuous adherent epithelium after EACA treatment. Conclusions. Topically administered EACA decreases both the severity and incidence of persistent epithelial defects produced by alkali burns to the cornea. EACA appears to promote adherence of the regenerating epithelium to the underlying stroma. Thus, topically administered EACA may be an effective treatment for this chronic condition.

Wagner: As you can see in the photographs, an 8-month-old infant presented with a right face turn, which has been present clearly ever since the mother can remember. There is no significant medical history and on examination you find a right face turn and a large exotropia in primary gaze. The eyes are aligned in gaze to the left, but on attempted gaze to the right there is absent adduction and increased abduction of the left eye, as shown in the photographs. There is no limitation of vertical eye movements, the retinal examination is normal, and the cycloplegic retinoscopy is +2.5 diopters in each eye. What is going on here and what would be your plan to treat this infant?

Purpose: To discuss major issues in the management of pediatric cataracts. Objectives and Synopsis: Pediatric cataract surgery continues to evolve. However, major issues persist: best method of optical correction, management of posterior capsule opacification (PCO), and aphakic glaucoma. Issues regarding myopic shift and unilateral cataract management will be presented with a balanced approach. Difficult patient cases with solutions developed by the panel will be presented.

Purpose: Current adjunctive therapies to glaucoma surgery have unreliable effects, are toxic, and have numerous late complications associated with their use. This study examined whether topical cyclosporin (CsA) prolongs bleb survival after glaucoma filtration surgery.Methods: Anesthetized white New Zealand rabbits underwent glaucoma filtration surgery with a drainage tube. Cyclosporin (2%), applied intraoperatively or as topical treatment following glaucoma filtration surgery, was compared with intraoperative mitomycin C (MMC) and an untreated control group.Results: The bleb remained elevated for 15.1 +/- 3.2 days in the untreated control group, 12.2 +/- 2.1 days after intraoperative cyclosporin, and 27.5 +/- 1.7 days after intraoperative mitomycin C (P < 0.001). When topical treatment with cyclosporin followed intraoperative mitomycin C, bleb survival significantly decreased to 19.2 +/- 4.6 days (P = 0.003). Intraocular pressure (IOP) remained significantly reduced in the mitomycin C-treated group longer than in either the control or cyclosporine-treated groups.Conclusions: In comparison with mitomycin C, neither intraoperative nor postoperative treatment with cyclosporin was associated with a decrease in intraocular pressure or prolonged bleb survival. Contrary to the initial hypothesis, topical treatment with cyclosporin actually mitigated the beneficial effects of mitomycin C on bleb survival. Clinical implications of these findings for patients with functioning blebs deserve further study.

OBJECTIVE To evaluate the effectiveness of treatment of amblyopia in children aged 7 to 17 years. METHODS At 49 clinical sites, 507 patients with amblyopic eye visual acuity ranging from 20/40 to 20/400 were provided with optimal optical correction and then randomized to a treatment group (2-6 hours per day of prescribed patching combined with near visual activities for all patients plus atropine sulfate for children aged 7 to 12 years) or an optical correction group (optical correction alone). Patients whose amblyopic eye acuity improved 10 or more letters (> or =2 lines) by 24 weeks were considered responders. RESULTS In the 7- to 12-year-olds (n = 404), 53% of the treatment group were responders compared with 25% of the optical correction group (P<.001). In the 13- to 17-year-olds (n = 103), the responder rates were 25% and 23%, respectively, overall (adjusted P = .22) but 47% and 20%, respectively, among patients not previously treated with patching and/or atropine for amblyopia (adjusted P = .03). Most patients, including responders, were left with a residual visual acuity deficit. CONCLUSIONS Amblyopia improves with optical correction alone in about one fourth of patients aged 7 to 17 years, although most patients who are initially treated with optical correction alone will require additional treatment for amblyopia. For patients aged 7 to 12 years, prescribing 2 to 6 hours per day of patching with near visual activities and atropine can improve visual acuity even if the amblyopia has been previously treated. For patients 13 to 17 years, prescribing patching 2 to 6 hours per day with near visual activities may improve visual acuity when amblyopia has not been previously treated but appears to be of little benefit if amblyopia was previously treated with patching. We do not yet know whether visual acuity improvement will be sustained once treatment is discontinued; therefore, conclusions regarding the long-term benefit of treatment and the development of treatment recommendations for amblyopia in children 7 years and older await the results of a follow-up study we are conducting on the patients who responded to treatment.

BACKGROUND AND OBJECTIVE Almost all patients develop iritis following argon laser peripheral iridoplasty. Numerous adverse effects, particularly elevated intraocular pressure (IOP) and reduced microbial resistance, complicate therapy with topical corticosteroids. An immunomodulator, such as cyclosporin A (CsA), avoids these undesirable effects, yet may suppress ocular inflammation. MATERIALS AND METHODS Argon laser peripheral iridoplasty was performed on anesthetized rabbits with pigmented iris epithelium. Rabbits were randomly assigned to the untreated control, CsA (2%), or dexamethasone (0.1%) groups. Postoperative inflammation was documented by digital photography, IOP, and protein in aqueous humor. RESULTS Iris injection, aqueous flare, and fibrin decreased most rapidly in the control group, as did protein in aqueous humor. Decreases in IOP of 49% to 58% were similar in all three groups. There were no differences in conjunctival congestion between the CONCLUSION Neither treatment with antiinflammatory drugs that inhibit phagocytosis (e.g., topical steroids) nor treatment with anti-inflammatory drugs that suppress T-lymphocytes (e.g., topical sA) significantly attenuated inflammation following iridoplasty.
