Myopia associated with retinopathy of prematurity.

A complete analysis of the components of refractive error was performed on ten eyes of five patients with myopia and retinopathy of prematurity (ROP). In comparison to an age-matched control group, these eyes exhibited both lenticular and axial myopia. Only the high crystalline lens powers, which ranged from 22.20 to 44.13 diopters (D) (mean value, 31.27 D), were found to be statistically significant. In two patients, only one eye had high myopia. The lens power in these eyes was approximately 11 D more powerful than the lens of the fellow eye. Further investigation into the ocular changes induced by prematurity and abnormal oxygen metabolism is needed to determine the reason for the high degree of lenticular myopia.
