Abstract

PURPOSE
To compare long-term refractive outcomes associated with intravitreal anti-vascular endothelial growth factor (VEGF) versus laser photocoagulation treatment for retinopathy of prematurity (ROP).
METHODS
A total of 52 eyes from 27 ROP patients treated at two tertiary referral-based hospitals from August 2006 to December 2013 were reviewed. The primary outcome was refractive error measured at the age of 4 years, accounting for within-patient inter-eye correlation. Secondary outcomes included the recurrence rate and treatment complications.
RESULTS
The mean age at refraction was 4.7 ± 0.3 years in the laser group (n = 30) and 4.4 ± 0.3 years in the anti-VEGF group (n = 22). No significant differences were noted in gestational age, birthweight, post-menstrual age at treatment, or ROP stage/zone distribution between groups. Mean spherical equivalent was also not significantly different (−1.0 diopters in the laser group and −0.3 diopters in the injection group, p = 0.603). Clustered regression analysis revealed that only gestational age was significantly correlated with mean spherical equivalent (p < 0.001; 95% confidence interval, −0.007 to −0.002). Recurrence was noted in four eyes (13.3%) in the laser group, but this difference was not significant (p = 0.128). There were no major systemic complications reported in either group.
CONCLUSIONS
Treatment type, whether laser or anti-VEGF injection, does not appear to influence long-term refractive outcomes in ROP. Concern regarding refractive outcomes should not be the most important factor when selecting ROP treatment modality.
