Abstract

BACKGROUND: There is increasing emphasis on the importance of intraocular pressure peaks and fluctuations as risk factors for glaucoma progression. It is well recognized that the water drinking test raises intraocular pressure and there is reasonable evidence that caffeine can also raise intraocular pressure. The aim of this study is to directly compare the effect of a caffeine test to that of the water drinking test on intraocular pressure, in patients with glaucoma. DESIGN: Prospective, observer-masked, cross-over study. PARTICIPANTS: Fourteen eyes of 14 patients with primary open-angle glaucoma. METHODS: Patients were initially randomized to either caffeine test or water drinking test. In..
