Abstract

Purpose: To assess quantitatively the biometric optic components and its relationship with refractive status in preterm school children with diode laser-treated threshold retinopathy of prematurity (ROP). Methods: A prospective, cross-sectional study in which ultrasound biometric measurement of optic components and cycloplegic refraction were performed on 24 consecutive preterm children with diode laser-treated threshold ROP at the age of 9 years. The study results were compared with 1021 age-matched full-term control children from a national survey. Results: The eyes with laser-treated ROP showed statistically significantly thicker lens (3.94 versus 3.39 mm), steeper vertical corneal curvature (7.47 versus 7.67 mm) and shallower anterior chamber depth (ACD) (2.91 versus 3.58 mm) than age-matched full-term controls, but no difference in axial length (23.32 versus 23.24 mm). The laser-treated eyes had a mean spherical equivalent (SE) of -4.49 D compared with mean SE of -0.44 D in controls. Of 46 eyes studied, 93% of eyes were myopic and 28.3% with high myopia (
