Vitreous Bands Identified by Handheld Spectral-Domain Optical Coherence Tomography Among Premature Infants

Importance: Handheld spectral-domain optical coherence tomography (SD-OCT) can provide insights into the complex interactions occurring at the vitreoretinal interface in retinopathy of prematurity (ROP) to enhance our understanding of ROP pathology. Objective: To characterize vitreous bands in premature infants with use of handheld SD-OCT. Design, Setting, and Participants: Prospective cohort study conducted from July 7, 2015, to February 28, 2017, at 2 university-based neonatal intensive care units. Seventy-three premature infants who required routine ROP screening examination were recruited. Informed consent was obtained from all legal guardians. Trained graders who were masked to the clinical assessment analyzed each SD-OCT scan of the right eye for vitreoretinal findings. A third trained grader mediated disagreements. Main Outcomes and Measures: Associations between the presence of vitreous bands in premature infants with ROP diagnoses and the presence of other vitreoretinal SD-OCT findings were investigated. Results: Of the 73 infants recruited, 6 infants\u27 parents withdrew their children from the study, and 2 infants were too hemodynamically unstable for imaging, leaving a total of 65 participants. Of these, 32 (49%) were female, 36 (55%) were white, 10 (15%) were Hispanic, 3 (5%) were Native American, 4 (6%) were African American, 4 (7%) were Asian/Pacific Islander, and 8 (12%) were other. The mean (SD) gestational age was 28 (2.7) weeks, the mean (SD) birth weight was 997 g (286 g), and the mean (SD) postmenstrual age at imaging was 34 (3) weeks (mean [SD] total of 3 [2] imaging sessions). Comparing the 24 infants (37%) who had a right eye vitreous band at any time with the 41 (63%) who did not, no difference in mean birth weight, gestational age, postmenstrual age at imaging, sex, or race/ethnicity was identified. No associations with ROP stage (eg, in 6 [25%] infants with vitreous bands vs 4 [9.8%] in those without; P = .23), presence of plus disease (2 [8%] vs 2 [5%]; P = .84), or type 1 ROP (3 [12%] vs 3 [7%]; P = .66) were identified. Vitreous bands were associated with epiretinal membrane detected on SD-OCT (P = .001) with an odds ratio of 9.4 (95% CI, 2.8-31.3) in 15 [62%] infants with vitreous bands vs 6 [15%] in those without. Vitreous bands were also associated with cystoid macular edema (in 15 [62%] infants with vitreous bands vs 1 [27%] in those without; P = .005) with an odds ratio of 4.5 (95% CI, 1.5-13.3). Conclusions and Relevance: In this study, the development of vitreous bands was associated with both cystoid macular edema and epiretinal membrane. These findings suggest a tractional pathogenesis to these entities among premature infants. This study did not find a direct association between vitreous bands and severe ROP. Additional study is needed to determine whether vitreous bands represent subclinical hyaloidal organization leading to retinal detachment in advanced ROP

Exudative retinal detachment documented by handheld spectral domain optical coherence tomography after retinal laser photocoagulation for retinopathy of prematurity

BACKGROUND: Few cases of exudative retinal detachments have been reported in the literature after laser treatment for retinopathy of prematurity, and none of the cases include optical coherence tomography images. METHODS: Case report. RESULTS: A 469-g birth weight, 25-week gestational age baby girl at 35-week postmenstrual age received a retinal laser (1,724 spots in the right eye and 1,287 spots in the left eye) for bilateral Stage 3 Zone II plus disease retinopathy of prematurity. The patient developed a large macular exudative retinal detachment seen in the right eye at the first follow-up, 5 days after the laser. Serial handheld optical coherence tomography demonstrated resolution of retinal detachment and intraretinal fluid over the course of 4 weeks with only topical tobramycin/dexamethasone ophthalmic ointment 3 to 4 times daily for 2 weeks. The patient was left with a residual subretinal scar and outer retinal loss on optical coherence tomography, with a later appearance of a dragged macula on funduscopic examination noted at 52-week postmenstrual age. It is unclear whether systemic steroid therapy, intravitreal bevacizumab, or surgery would hasten resolution of exudative retinal detachment after the retinopathy of prematurity laser and avoid photoreceptor damage seen on optical coherence tomography in this case. CONCLUSION: This case suggests that post-retinopathy of prematurity laser exudative retinal detachments can resolve without aggressive intervention, but may cause permanent retinal sequelae

Prevalence of Comprehensive Eye Examination in Preschool Children With Eye Conditions

IntroductionThe purpose of this study is to assess the prevalence of comprehensive eye examinations in multiethnic preschool children, including children with visually significant eye conditions, and identify factors associated with comprehensive eye examinations.MethodsA sample of 9,197 African American, Hispanic, Asian American, and non-Hispanic White children aged 6-72 months was recruited for the Multi-Ethnic Pediatric Eye Disease Study from 2003 to 2011. Logistic regression performed in 2022 identified independent factors associated with parent-reported history of comprehensive eye examinations. The proportion of children with previous comprehensive eye examinations and the proportion with undetected amblyopia or strabismus were measured.ResultsThe prevalence of comprehensive eye examinations was 6.3% overall and 38.3%, 24.8%, 19.1%, 15.1%, and 9.8% among children with strabismus, amblyopia, significant anisometropia, hyperopia, and astigmatism, respectively. Children without prior comprehensive eye examinations were more likely to have undetected amblyopia or strabismus than those with comprehensive eye examination history (ps<0.001). The prevalence of comprehensive eye examinations was higher among older children. Prevalence varied by race/ethnicity, with 8.1%, 7.9%, 6.3%, and 4.9% of non-Hispanic White, Asian American, African American, and Hispanic children having had prior comprehensive eye examinations, respectively; however, the differences did not remain after adjusting for other associated factors. Older age, a primary caregiver with a college/university degree or higher, having vision insurance, gestational age <33 weeks, neurodevelopmental disorder diagnosis, strabismus, and ocular disease history were all statistically significantly associated with a relatively higher prevalence of comprehensive eye examinations in multivariable analyses.ConclusionsComprehensive eye examinations were uncommon among preschool children, including those with treatable vision disorders. Interventions, such as parent education and vision insurance, are needed to imaprove comprehensive eye examination access and utilization for at-risk preschool children

Dome-shaped macula in premature infants visualized by handheld spectral-domain optical coherence tomography

PURPOSE: To describe dome-shaped macula and associated clinical findings in premature infants. METHODS: This prospective, observational cohort study included a consecutive sample of premature infants screened for retinopathy of prematurity (ROP) with 9-month follow-up. Handheld spectral domain optical coherence tomography (SD-OCT) was performed at the time of ROP screening. Images were assessed for dome-shaped macula, cystoid macular edema, epiretinal membrane, vitreous bands, and punctate hyperreflective vitreous opacities. Dome height measurements were performed in a subset of images. Teller visual acuity and cycloplegic refraction were performed at an adjusted age of 8-10 months. RESULTS: Of 37 infants (74 eyes; 49% male; mean gestational age 27.8 ± 3.2 weeks; mean birth weight 949 ± 284 g), 24/37 (65%) demonstrated dome-shaped macula in at least one eye (13 both eyes, 5 right eye only, and 6 left eye only). Of the 74 eyes, 26 (35%) could be reliably measured, with a mean dome height of 139.0 ± 72.3 μm (range, 54-369 μm). Presence of dome-shaped macula was associated with a diagnosis of ROP (P = 0.02; OR, 3.03; 95% CI, 1.18-7.82) and pre-plus or plus disease (P = 0.02; OR, 4.20; 95% CI, 1.05-16.78). Infants with dome-shaped macula had lower birth weight compared with those without (877 vs 1081 g; P = 0.04). No associations with other demographics, OCT findings, and 9-month refractive outcomes were found. CONCLUSIONS: Dome-shaped macula was frequently identified by handheld SD-OCT in premature infants, especially those with lower birth weight and severe ROP. The long-term clinical significance of this finding is unknown
