Refractive error, axial length, and relative peripheral refractive error before and after the onset of myopia.

PURPOSE To evaluate refractive error, axial length, and relative peripheral refractive error before, during the year of, and after the onset of myopia in children who became myopic compared with emmetropes. METHODS Subjects were 605 children 6 to 14 years of age who became myopic (at least -0.75 D in each meridian) and 374 emmetropic (between -0.25 D and +1.00 D in each meridian at all visits...

Relative peripheral refractive error and the risk of onset and progression of myopia in children.

PURPOSE To investigate whether relative peripheral hyperopia is a risk factor for either the onset of myopia in children or the rate of myopic progression. METHODS The risk of myopia onset was assessed in 2043 nonmyopic third-grade children (mean age ± SD = 8.8 ± 0.52 years) participating in the Collaborative Longitudinal Evaluation of Ethnicity and Refractive Error (CLEERE) Study between 199...

Parental myopia, near work, school achievement, and children's refractive error.

PURPOSE To quantify the degree of association between juvenile myopia and parental myopia, near work, and school achievement. METHODS Refractive error, parental refractive status, current level of near activities (assumed working distance-weighted hours per week spent studying, reading for pleasure, watching television, playing video games or working on the computer), hours per week spent pla...

Refractive error and axial length in a primate model of strabismus and congenital nystagmus.

PURPOSE To evaluate the development of refractive error and axial length in a primate model of sensory strabismus and nystagmus. METHODS Four macaque monkeys had alternating tarsorraphy beginning within 24 hours of birth. One eye was closed for 25 days, and when it opened, the second eye immediately was closed for the next 25 days. Cycloplegic refractions and axial lengths were determined pro...

Influence of refractive error and axial length on retinal vessel geometric characteristics.

PURPOSE To evaluate the influence of refractive error and axial length (AL) on retinal vascular network geometry measurements in an adult Asian population. METHODS This was a population-based, cross-sectional study on 2882 persons with diabetes in the Singapore Malay Eye Study. Spherical equivalent refraction was assessed using an autokeratorefractometer and subjective refraction. AL retinal ...
