Simpler screening method effective for detecting significant ametropia

LONDON — A noncycloplegic screening process can be effective in detecting a large proportion of infants with significant ametropia, particularly those with significant hyperopia, according to a study.

Shirley Anker and colleagues here at University College London screened 5,142 children born over a 2-year period to be screened for accommodative errors. Mean age at time of screening was 8 months, and each child received noncycloplegic videorefraction and an orthoptic exam. Of those children, 514 had a focusing error or orthoptic problem; 439 attended follow-up. A refractive or orthoptic condition was confirmed in 59% of these infants. Of the normal control patients, 96.8% were confirmed normal.

The study is published in the February issue of Investigative Ophthalmology & Visual Science.
