Purpose: The purpose was to study the incidence, risk factors, and anatomical outcomes after laser treatment in retinopathy of prematurity (ROP). Methods: A retrospective observational study was carried out. Infants admitted to Neonatal Intensive Care Unit of 12 referral hospitals between April 2016 and September 2017 were screened according to the latest Indian guidelines based on the International Classification of Retinopathy of Prematurity. Results: The incidence of ROP in 1648 eyes screened was 25.36% (418 eyes), out of which high-risk prethreshold ROP (type 1) was observed in 9.95% (164 eyes). Decreased hemoglobin (P < 0.001), oxygen requirement (P = 0.008), and number of blood transfusions (P = 0.037) were significant with type 1 than type 2 (low-risk prethreshold) ROP. Stages 1, 2, and 3 were observed in 82 (32.28%), 154 (60.62%), and 18 (7.08%) eyes, respectively. Aggressive posterior ROP (APROP) was observed in 20.73% eyes with type 1 ROP. Ten eyes showing APROP were treated at an early gestational age of 29 weeks. All infants with type 1 ROP were treated with laser photocoagulation only. Conclusion: One-fourth of the infants showed ROP and one-tenth needed laser photocoagulation, the outcome of which was excellent. Risk factors predisposing to ROP were anemia, high oxygen supplementation, increased number of blood transfusions, and septicemia. ROP screening in infants ≥1700 g birth weight associated with various systemic risk factors may be beneficial in the Indian population.
