Structural Sequelae and Refractive Outcome After Successful Laser Treatment for Threshold Retinopathy of Prematurity

PURPOSE: To study the structural sequelae and refractive outcome in eyes with a favorable structural outcome following laser treatment for threshold retinopathy of prematurity (ROP). METHODS: Premature infants with threshold ROP had laser treatment with a minimum follow-up of 1 year. Complete ocular examination and refraction was done. Analysis and correlation of structural sequelae and refractive outcome was done. RESULTS: One hundred eighty-four eyes of 93 preterm infants were followed up. Structural changes such as vascular tortuosity, narrowing of arcades, temporal crescent, disc drag, and macular heterotopia were seen. Mean refractive error observed was -4.71 D spherical equivalent. Myopia was seen in 80.43% of eyes. CONCLUSIONS: The study revealed various structural sequelae and their correlation with refractive outcome.
