Development of Spherical Equivalent Refraction in Prematurely Born Children During the First 10 Years of Life

Objective

To evaluate the development of refraction, expressed as spherical equivalents, in prematurely born children during the first 10 years of life.

Methods

Retinoscopy in cycloplegia was performed at 6 months, 2.5 years, and 10 years of age in 198 prematurely born children from a previous population-based study on the incidence of retinopathy of prematurity. Spherical equivalents were calculated. Myopia was defined as a...
