title: Estimating intraocular pressure using a glass rod.
abstract: Four masked examiners studied the usefulness of the glass-rod for estimating intraocular pressure (IOP) in a living, anesthetized rabbit eye manometrically set to 135 different random values. With training, the average error in IOP estimation improved from 7.42 +/- 5.56 mmHg to 5.13 +/- 4.48 mmHg. Gentle palpation of the corneal apex with a glass-rod provides tactile and visual clues that may assist in estimating the IOP.
