Abstract
Purpose: To compare the outcomes of conventional laser photocoagulation versus additional posterior barrage laser in advanced stage 3 retinopathy of prematurity (ROP). Methods: A total of 20 infants with bilateral symmetric zone 2 stage 3 advancing ROP were treated with conventional laser treatment followed by randomization of one eye to receive additional posterior retinal laser treatment. Disc–fovea and inter-arcade distance was measured. The patients were followed up prospectively for 3 months. Structural and functional outcomes and safety profile were analyzed. Results: 18/20 (90%) eyes in the study group and 19/20 (95%) eyes in the control group achieved regression of disease. Faster and complete regression was observed at 4 weeks after posterior laser compared to the control group (P = 0.024). Disc–fovea and inter-arcade distance was comparable in both groups. Conclusion: Additional posterior barrage laser is a safe technique that led to faster and more complete regression in eyes with advancing ROP. Final regression profile was comparable in both treatment modalities.
