ABSTRACT
Aim:
The aim was to study the structural sequelae and refractive outcome after laser treatment for Type 1 prethreshold retinopathy of prematurity (ROP) in Asian Indian eyes. Materials andMethods:
A retrospective chart review of infants with Type 1 prethreshold ROP (defined according to the Early Treatment for Retinopathy of Prematurity study) undergoing laser treatment at a tertiary center between January 2004 and December 2008 was done. The 1-year outcome of infants was analyzed.Results:
Sixty-nine eyes of 36 infants were included. The mean birth weight was 1121.69 ± 254.81 g and the gestational age was 28.99 ± 2.03 weeks. Sixty-five eyes (94.2%) had zone 2 and 4 (5.8%) had zone 1 disease. Forty-four (63.77%) eyes had stage 2 ROP with plus disease and 25 (36.23%) eyes had prethreshold (fewer than five contiguous or eight cumulative clock hours) stage 3 ROP with plus disease. None of the eyes developed retinal structural sequelae. On cycloplegic retinoscopy, 59.4% eyes had nonsignificant hyperopia [spherical equivalent (SE) ≤ 4 D], 14.5% eyes had no refractive error (SE 0 D), 24.7% eyes had low myopia (SE < 5 D), and 1.4% eyes had high myopia (SE > 5.0 D). Eyes developing myopia were associated with a greater number of clock hours of ROP, greater number of laser spots used, and a longer time to disease regression. Two infants (5.6%) had esotropia and one (2.8%) had exotropia.Conclusion:
Asian Indian infants treated for Type 1 prethreshold ROP did not develop retinal structural sequelae. Myopia was seen in nearly one-fourth of the eyes.The risk factors for myopia were a greater number of clock hours of ROP, greater number of laser spots, and a longer time to regression of ROP.
