PURPOSE: The purpose is to study the anatomical outcome of eyes in aggressive retinopathy of prematurity (AROP), treated with laser photocoagulation alone and to evaluate factors affecting outcomes.
METHODS: Records of consecutive babies diagnosed with AROP, undergoing laser photocoagulation treatment in rural tertiary care centers from October 2016 to January 2021 were reviewed retrospectively. Anatomical outcome at 6 months follow-up was grouped as good in eyes with complete regression and poor in those who developed retinal detachment (stage IV a, IV b, and V). Both groups were compared with respect to the period of gestation, birth weight (BW), age at screening, age at treatment, zone of disease, presence of retinal fibrovascular proliferation (FVP), tunica vasculosa lentis, preretinal bleed, need for supplement laser, and associated systemic risk factors.
RESULTS: Of the total of 2468 babies screened, 124 (5.02%) were diagnosed with severe retinopathy of prematurity (ROP), of which 54 (43.5%) lasered AROP babies were analyzed. Mean BW and gestation period of the AROP cohort were 1.43 kg and 31.1 weeks, respectively. Eighty-six eyes (79.6%) had good outcomes with laser photocoagulation alone. Posterior location of disease, presence of FVP, neonatal sepsis, shock, and late screening for ROP were found to be factors associated with poor outcomes.
CONCLUSION: Adequate and timely treatment with laser photocoagulation in AROP can achieve good treatment outcomes in a significant proportion of babies. Although a combined approach using laser, anti-vascular endothelial growth factor and early vitrectomy is better, laser remains a viable treatment option in AROP, especially with limited resources and high risk of loss to follow-up.
