Abstract

Purpose: This study aims to report the association of optic nerve hypoplasia (ONH), peripheral retinal nonperfusion, and secondary complications in pediatric patients.

Design: Retrospective case series.

Methods: The study was conducted between January 2015 and January 2022 at the Bascom Palmer Eye Institute. Inclusion criteria were clinical diagnosis of optic disc hypoplasia, age <18 years, and a fluorescein angiography (FA) of acceptable quality.

Results: Seven patients (11 eyes) met inclusion criteria. Average age at presentation was 3.5 years (range 1 month-8 years) and the mean follow-up time was 34.28 months (range 2-87 months). Four patients (57.14%) showed bilateral optic disc hypoplasia. All eyes exhibited peripheral retina nonperfusion on FA, in which mild severity was found in 7 eyes (63.63%), moderate in 2 eyes (18.18%), severe in 1 eye (9.09%) and extreme in 1 eye (9.09%). Eight eyes (72.72%) showed evidence of 360 degrees of retinal nonperfusion. Two patients (18.18%) were diagnosed with concurrent retinal detachment that were deemed inoperable at the time of diagnosis. All cases were observed without intervention. None of the patients were observed to have complications during follow-up.

Conclusion: Among pediatric patients with ONH, there appears to be a high rate of concurrent retinal nonperfusion. In these cases, FA is a helpful tool to detect peripheral nonperfusion. Retinal findings are subtle in some cases and may not be detectable in children with suboptimal imaging performed without examination under anesthesia.
