title: The effect of repeated measurements and the use of topical anesthetic on rebound tonometry values in children.
abstract: Measurement of intraocular pressure (IOP) in children is important in the management of pediatric glaucoma. Availability of the Icare rebound tonometer has greatly facilitated our ability to obtain awake IOP in infants and children, but little has been reported on either the effect of repeated sequential IOP measurements with Icare or the effect of topical anesthetic on subsequent Icare tonometry. This prospective study of 20 eyes of 10 cooperative children (12 normal eyes, 8 with suspected or known glaucoma) found that neither 8 sequential Icare measurements nor application of topical anesthetic produced a statistically or clinically signficant change in measured IOP by rebound tonometry.
