Abstract

In a prospective double-blind randomised trial the interaction of timolol and adrenaline was studied in 20 patients with open-angle glaucoma and exfoliative glaucoma. After pretreatment for at least 2 weeks with timolol eyedrops adrenaline was added in a double-blind manner, and the intraocular pressure was recorded during 4 days. The study showed a significantly additive hypotensive effect of adrenaline, which was more pronounced in patients with exfoliative glaucoma.
