Abstract
PURPOSE: To evaluate structural features and visual outcomes in eyes with a prior history of laser treatment for retinopathy of prematurity (ROP). METHODS: Laser-treated eyes for type 1 ROP, preterm monitored eyes, and full-term control eyes were included. LogMAR conversion of Snellen best-corrected visual acuity and spherical equivalent based on cycloplegic refraction were measured in children 5-15 years of age. Anterior segment optical coherence tomography (OCT) was used to study structural features, including anterior chamber angle (ACA) in a subset of eyes. RESULTS: A total of 50 eyes of 50 patients were included (19 full-term eyes, 19 laser-treated type 1 ROP eyes, 12 preterm monitored eyes). Of these, 44 eyes had visual outcomes data, and 15 eyes had anterior segment data. There was no significant difference in sex or age at final examination between the three groups. There was no significant difference in gestational age between the laser-treated and preterm monitored groups. Compared with the full-term control group and the preterm monitored group, the laser-treated ROP group had narrower ACA and more myopic refractive error. There was a significant correlation between ACA and spherical equivalent. CONCLUSIONS: Laser treatment may affect angle configuration in ROP eyes. Anterior segment OCT is an easy and useful modality that could aid in screening for visually impairing conditions such as myopia and glaucoma in children with ROP.
