RESUMO
Aberrant regeneration occurs in forms of oculomotor motor nerve palsy and frequently involves the pupil, but the incidence and functional impact of ciliary muscle involvement in pediatric patients is sparsely reported in the literature. A 4-year-old girl presented with inflammatory oculomotor motor nerve paresis affecting the inferior division. Initial treatment focused on her inability to accommodate through her physiologic +2.5 D hyperopia and the prevention and treatment of amblyopia. She subsequently developed aberrant regeneration of the pupil, with miosis on adduction. Following eye muscle surgery for residual exotropia and hypertropia, her dry refraction was noted to be more myopic in the affected eye on adduction, mirroring aberrant pupillary constriction. Recognition of pediatric aberrant regeneration of accommodation may influence surgical planning for oculomotor nerve palsy and/or management of amblyopia.

A healthy 32-year-old woman presented with binocular diplopia immediately after sustaining a penetrating injury to the left periocular adnexa with a hot metal skewer. Examination revealed an incomitant esotropia, with complete limitation of abduction of the left eye with downshoot in left gaze and normal afferent visual function. Computed tomography and magnetic resonance imaging demonstrated no fracture, but there was mild thickening of the medial rectus muscle and associated fat stranding. Lack of orbitomuscular tethering or hematoma led to the presumptive diagnosis of thermal cauterization injury causing left medial rectus restriction. Given the lack of literature on this mechanism of injury, the patient was monitored closely. She exhibited remarkable spontaneous improvement in motility over 6 months, with near orthophoria in primary gaze. However, bothersome residual esotropic diplopia in left gaze prompted a left medial rectus recession, with a good outcome. This case demonstrates that isolated extraocular muscle thermal injuries and consequential strabismus can recover spontaneously; longitudinal observation before surgical intervention may be appropriate in such cases.

PURPOSE: Convention is to perform open globe injury (OGI) repair within 24 h to minimize risk of endophthalmitis. However, there are limited data assessing how time to operative repair (OR) within 24 h impacts postoperative visual acuity (VA). METHODS: Manual retrospective chart review of 633 eyes at Massachusetts Eye and Ear (MEE) with a diagnosis of OGI between 2012 and 2022. Inclusion criteria were primary repair ≤ 24 h after injury and ≥1 month follow-up. Multivariate regression analysis was conducted with postoperative VA as primary outcome. RESULTS: Of the subjects, 489 (77.3%) were male and 496 (78.4%) were white. Demographics of OGI wounds included 320 (50.6%) rupture and 313 (49.4%) laceration; 126 (19.9%) with rAPD, 189 (29.9%) zone 3 injuries, 449 (71.2%) uveal prolapse, and 110 (17.4%) intraocular foreign body. Final postoperative LogMAR VAs consisted of 31% with a VA < 1.7, 9% with a VA of 1.9, 18% with a VA of 2.3, 27% with a VA of 2.7, and 11% with a VA of 3.0. Multivariate analysis showed no significant correlation between time to OR and postoperative VA (p = 0.800) [95%CI: -0.01,0.01]. Older age (p < 0.001) [95%CI: 0.00,0.01], worse presenting VA (p < 0.001) [95%CI: 0.17,0.32], rAPD (p < 0.001) [95%CI: 0.65,1.0], mechanism of rupture (p < 0.001) [95%CI: 0.19,0.54], higher zone of injury (p < 0.001) [95%CI: 0.25,0.45], and uveal prolapse (p = 0.003) [95%CI: 0.09,0.42] were significantly associated with worse final VA. CONCLUSIONS: Time to repair of OGIs within 24 h does not influence final VA. Optimization of surgical and patient factors may contribute more significantly to final VA than prioritizing more rapid time to OR.

Semiautomated computer software (ie, ROPtool) can trace and analyze optical coherence tomography (OCT)-generated retinal vessel maps for plus/pre-plus disease with high reliability and accuracy. This proof-of-concept study found that ROPtool can reliably rank OCT-generated vessel maps for tortuosity and combined tortuosity/dilation, which correlated well with human-expert rankings and clinical examination.

Importance: Uncorrected refractive error is the most common cause of vision impairment in children. Most children 12 years or older can achieve visual acuity (VA) of 20/25 or better by self-refraction using adjustable-focus spectacles, but data on younger children are lacking. Objective: To assess refractive accuracy, corrected VA, and factors associated with not achieving VA of 20/25 or better among children aged 5 to 11 years performing self-refraction with Adspecs adjustable-focus spectacles (Adaptive Eyecare), compared with noncycloplegic autorefraction and cycloplegic refraction. Design, Setting, and Participants: This was a cross-sectional noninferiority trial conducted from September 2, 2015, to December 14, 2017. The study setting was an academic pediatric eye clinic. Children aged 5 to 11 years with uncorrected VA of 20/40 or worse in 1 or both eyes and without systemic or ocular conditions preventing best-corrected VA of 20/25 or better were enrolled. Children who had best-corrected VA worse than 20/25 were excluded. Study data were analyzed from September 2017 to June 2023. Exposures: Children were taught to self-refract with adjustable-focus spectacles. Main Outcomes and Measures: Spherical equivalent refractive error (using self-refraction, noncycloplegic autorefraction, and cycloplegic refraction) and VA (uncorrected and using self-refraction, noncycloplegic autorefraction, and cycloplegic refraction) for study eyes were evaluated. Potential predictors of failure to achieve VA of 20/25 or better with self-refraction were assessed using logistic regression. Results: A total of 127 consecutive children were enrolled. After exclusions, 112 children (median [IQR] age, 9.0 [8.0-10.3] years; 52 boys [46.4%]) were included in the study. Mean (SD) spherical equivalent refractive power was -2.00 (1.52) diopters (D) for self-refraction, -2.32 (1.43) D for noncycloplegic autorefraction, and -1.67 (1.49) D for cycloplegic refraction. Mean (SD) difference in refractive power between self-refraction and noncycloplegic autorefraction was 0.32 (1.11) D (97.5% 1-sided CI, 0.11 to ∞ D; P < .001) and between self-refraction and cycloplegic refraction was -0.33 (1.15) D (97.5% 1-sided CI, -0.54 to ∞ D; P = .77). The proportion of children with corrected VA of 20/25 or better was 79.5% (89 of 112) with self-refraction, 85.7% (96 of 112) with noncycloplegic autorefraction, and 79.5% (89 of 112) with cycloplegic refraction (self-refraction vs noncycloplegic autorefraction: McNemar P value = .27; self-refraction vs cycloplegic refraction: McNemar P value > .99). Those failing to achieve best-corrected VA of 20/25 or better with self-refraction had higher astigmatism (odds ratio [OR], 10.6; 95% CI, 3.1-36.4; P < .001) and younger age (OR, 1.5; 95% CI, 1.1-2.2; P = .02). Conclusions and Relevance: Self-refraction among children aged 5 to 11 years may result in more myopic power than cycloplegic refraction but not necessarily to a clinically relevant degree. Although the proportion of children achieving VA of 20/25 or better with self-refraction using adjustable-focus spectacles did not differ from cycloplegic refraction, it was less likely among younger children and those with higher astigmatism.

PURPOSE: This proof-of-concept study evaluates the ability to assess eyelid measurements and the reproducibility of eyelid measurements using a simple measurement tool paired with digital cell phone photography in children. METHODS: Seventy consecutive patients and their siblings, 2-19 years of age, were prospectively enrolled. Participants underwent clinical examination and cell phone photography with a simple measurement tool. An ophthalmologist and nonophthalmologist assessed photographs for interpalpebral fissure distance (IPFD), margin reflex distance-1 (MRD1), and levator function (LF). Clinical examinations and photographs were repeated on the same day in a random sample (n = 20). The agreement of grading photographs compared to clinical examination was assessed using Bland-Altman plots. Intra-grader repeatability of the clinical examination, repeatability of photographic technique, and interobserver reproducibility of photographic assessment was evaluated with intraclass correlation coefficients (ICC). RESULTS: Of photographs acquired, both graders considered quality good/fair in 100% to assess IPFD and MRD1, and 70% to assess LF. The mean difference (limits of agreement) in mm between clinical examination and photographic assessment was 1.1 (-1.5 to 3.8) for IPFD, 0.7 (-1.8 to 3.1) for MRD1, and 1.1 (-3.5 to 5.7) for LF. Intraobserver repeatability on clinical examination was excellent for IPFD (ICC = 0.81), MRD1 (ICC = 0.88), and LF (ICC = 0.94). Repeatability of photographic technique was fair for IPFD (ICC = 0.44) and good for MRD1 (ICC = 0.74) and LF (ICC = 0.77). Interobserver photographic assessment repeatability was excellent for IPFD (ICC = 0.94), MRD1 (ICC = 0.96), and LF (ICC = 0.92). CONCLUSIONS: Photographic assessment of eyelid measurements in children is possible, highly reproducible between graders, and enables documentation for future comparison.

PURPOSE: To quantitatively compare retinal vascular characteristics over time in eyes eventually treated versus not treated for retinopathy of prematurity (ROP), using ROPtool analysis of narrow-field retinal images. METHODS: This longitudinal study used prospectively collected narrow-field retinal images of infants screened for ROP, prior to treatment, if needed. Images were analyzed using a methodology that combines quadrant-level measures from several images of the same eye. For the longitudinal analysis, one examination per postmenstrual age (PMA) was included per eye. We compared the following ROPtool indices and their change per week between eyes eventually treated versus not treated for ROP: tortuosity index (TI), dilation index (DI), sum of adjusted indices (SAI), and tortuosity-weighted plus (TWP). Analysis was performed on three levels: eye (mean value/eye), quadrant (highest quadrant value/eye), and blood vessel (highest blood vessel value/eye). RESULTS: Of 832 examinations (99 infants), 745 images (89.5%) had 3-4 quadrants analyzable by ROPtool. On the eye level, ROPtool indices differed between eyes eventually treated versus not treated at PMA of 33-35 and 37 weeks for TI, SAI, and TWP, and at PMA of 33-34 and 37 weeks for DI (P ≤ 0.0014), and change per week differed between eyes eventually treated versus not treated only for SAI at PMA of 32 weeks (P < 0.001). CONCLUSIONS: Quantitative analysis of retinal vascular characteristics using ROPtool can help predict eventual need for treatment for ROP as early as 32 weeks PMA. ROPtool index values were more useful than change in these indices to predict eyes that would eventually need treatment for ROP.

BACKGROUND: The presence of plus disease is important in determining when to treat retinopathy of prematurity (ROP), but the diagnosis of plus disease is subjective. Semiautomated computer programs (eg, ROPtool) can objectively measure retinal vascular characteristics in retinal images, but are limited by image quality. The purpose of this study was to evaluate whether ROPtool can accurately identify pre-plus and plus disease in narrow-field images of varying qualities using a new methodology that combines quadrant-level data from multiple images of a single retina. METHODS: This was a cross-sectional study of previously collected narrow-field retinal images of infants screened for ROP. Using one imaging session per infant, we evaluated the ability of ROPtool to analyze images using our new methodology and the accuracy of ROPtool indices (tortuosity index [TI], maximum tortuosity [Tmax], dilation index [DI], maximum dilation [Dmax], sum of adjusted indices [SAI], and tortuosity-weighted plus [TWP]) to identify pre-plus and plus disease in images compared to clinical examination findings. RESULTS: Of 198 eyes (from 99 infants) imaged, 769/792 quadrants (98%) were analyzable. Overall, 98% of eyes had 3-4 analyzable quadrants. For plus disease, area under the curves (AUCs) of receiver operating characteristic curves were: TWP (0.98) > TI (0.97) = Tmax (0.97) > SAI (0.96) > DI (0.88) > Dmax (0.84). For pre-plus or plus disease, AUCs were: TWP (0.95) > TI (0.94) = Tmax (0.94) = SAI (0.94) > DI (0.86) > Dmax (0.83). CONCLUSIONS: Using a novel methodology combining quadrant-level data, ROPtool can analyze narrow-field images of varying quality to identify pre-plus and plus disease with high accuracy.
