Purpose: To analyse the outcome of solid-state green laser in high-risk retinopathy of prematurity. Methods: Fifty-nine eyes of 30 infants with high-risk ROP were recruited in this prospective, interventional study.Laser photocoagulation was performed with 532 nm solid-state green laser. Results: Of the 30 infants, 18 were males (60%) and 12 were females (40%). The mean birth weight was 1102.83 ± 196.27 grams. The mean gestational age was 29.5 ± 1.47 weeks. The infants received mean 2710.24 ± 747.97 laser spots. Fifty (84.8%) eyes underwent laser in a single sitting and 9 eyes (15.2%) required 2 laser sittings. Mean time for regression of ROP was 5.8 ± 3.8 weeks. Total ROP regression was seen in 55 eyes (93.22%). Despite laser treatment, 4 (6.78%) eyes of three infants had unfavourable outcome. One infant developed intraprocedural bradycardia. Vitreous haemorrhage was seen in five eyes (8.4%). Conclusion: Solid-state 532 nm green laser is safe and effective treatment for high-risk ROP.
