Research output: Contribution to journalConference articlepeer-review


A study was carried out to compare the cyclophegic effect of tropicamide 1% and cyclopentolate 1% in 29 healthy, nonstrabismic infants 4 to 7 months of age (mean age 5.71 months). Each study subject was examined at 2 separate visits an average of 2 weeks apart. The examiner completed a case history, iris color grading, confrontation tests, non-cycloplegic near retinoscopy in a dark room, and then instilled a drop of topical anesthetic in each eye followed by two drops of cycloplegic agent separated by 5 minutes. Retinoscopy was performed after 20 minutes. The bottles were masked and the drop administered at the first visit was randomly assigned. Results suggest that the cycloplegic effect of tropicamide is comparable to cyclopentolate in healthy, nonstrabismic infants.
