Normal response to pilocarpine and phenylephrine

R Mapstone. Br J Ophthalmol. 1977 Aug.

Abstract

Fifty-eight eyes from 58 patients in which there was no evidence of glaucoma were provoked with pilocarpine and phenylephrine drops. The result was a significant reduction in intraocular pressure and a significant increase in outflow facility. The 58 eyes were randomised and 19 submitted to a 'dummy' provocative test. There was no significant change in either pressure or outflow facility. The effect of the pilocarpine/phenylephrine provocative test in normal eyes is to produce a response that is the opposite of a positive provocative test in eyes at risk of developing closed-angle glaucoma.
