Abstract

To assess the long-term refractive and biometric outcomes of diode laser-treated eyes in threshold retinopathy of prematurity (ROP). Cycloplegic autorefraction and biometry were performed, at a mean follow-up of 11 years, on 16 laser-treated eyes with threshold ROP and 9 comparison eyes with subthreshold untreated ROP. The laser treated eyes had a mean spherical equivalent of - 2.33 D with a mean astigmatic error of 1.38D. The comparison eyes had a mean spherical equivalent of +1.07 D with a mean astigmatic error of 0.42D. This trend toward increaded myopia in treated eyes did not achieve statistical significance. The myopia in the laser group appeared to be slowly progressive in nature when compared with earlier refractive data for these patients. The laser treated eyes had reduced anterior chamber depth (ACD) compared with the subthreshold eyes.
