Infants experience significantly less stress when retinal examination is done by digital fundus camera rather than by conventional indirect ophthalmoscopy, a study shows.

Patrick Watts, FRCOphth, and colleagues at the University Hospital of Wales prospectively compared cardiorespiratory indices of 86 preterm or underweight infants being screened for retinopathy of prematurity. Researchers used binocular indirect ophthalmoscopy to evaluate 34 infants and a fundus camera for 52 infants, according to the study.

Both groups experienced a significant increase in heart rate and blood pressure. However, infants examined by indirect ophthalmoscopy showed a significantly higher heart rate and respiratory rate than infants examined by a fundus camera (P < .05), the authors noted.

Fundus photography exams took significantly longer to complete (P < .001), they noted.

The study is published in the September issue of Ophthalmology.
