PURPOSE: To study the ocular hypotensive effect of pilocarpine in latanoprost-treated eyes. METHODS: The authors measured the IOP in both eyes of 25 patients, before and after the instillation of pilocarpine 2% in one eye and placebo in the other. This was a prospective, double blind, placebo-controlled study. RESULTS: The authors found that the mean change in IOP in the study eyes was +0.4 on average (range, -3 to +5 mmHg) compared with the control, placebo-treated eyes (p = 0.5). CONCLUSIONS: The acute administration of pilocarpine in latanoprost-treated eyes seems to have a paradoxical effect on IOP, since the IOP may increase or decrease. LA: Spanish
