Long-term outcomes of prostaglandin analog versus timolol maleate in ocular hypertensive or primary open-angle glaucoma patients in Europe.

Purpose: To determine the direct costs of therapy over 5 years of a European monotherapy cohort begun on a prostaglandin (PTG) versus timolol in patients with primary open-angle glaucoma or ocular hypertension.

Methods: A retrospective, multicenter, active-controlled, observational study. Data were abstracted for European patients treated as initial monotherapy in 1996 or afterward, with 5 years of available records.
