WASHINGTON — Wavefront analysis was found to be as effective as cycloplegic retinoscopy for measuring refractive errors in children, according to a poster presentation here at the American Association for Pediatric Ophthalmology and Strabismus meeting.
David B. Granet, MD, FACS, and colleagues at the Abraham Ratner Children’s Eye Center in San Diego presented the results of a study comparing wavefront autorefraction to cycloplegic retinoscopy, the gold standard method of measuring refraction in children.
Twenty-three eyes of 12 pediatric patients, aged 6 to 13 years, were measured with a wavefront device and with cycloplegic retinoscopy. Outcomes were analyzed with a one-sample T-test analysis.
A difference of ± 0.25 D and ± 0.50 D was initially found between the two methods of measurement. After compensating for differences, researchers found similar outcomes between wavefront refraction and cycloplegia.
The authors said wavefront technology has the potential to measure refraction reliably in children. Future study may even find wavefront to offer advantages of accuracy over traditional methods of refraction, the authors said.
