ABSTRACT
Objectives: To compare the efficacy and tolerance of a new latanoprost formulation
vs. those of travoprost in patients with primary open-angle glaucoma or ocular hypertension.
Materials and methods: A prospective, randomized and double blind study was carried out. Patients with primary openangle glaucoma or ocular hypertension were enrolled. As an efficacy primary parameter, the intraocular pressure was
evaluated. Conjunctival hyperemia and tearing were evaluated as a safety and tolerance parameters, respectively. The patients were included randomly in two therapy groups, one receiving latanoprost and the other one travoprost. Intraocular pressure daytime curves were performed.
Results: 30 patients were included: 21 females, 9 males (average age of 59.3 ±8 years old). Both medicaments diminished the intraocular pressure in a similar way without statistically significant differences found (p›0.05), even in the pressure daytime curve. The travoprost group showed a higher percentage of patients with conjunctival hyperemia, burning sensation and tearing with a statistically significant difference in favor of latanoprost (p‹0.05) regarding both parameters.
Conclusions: The new formula of latanoprost 0.005% shows a hypotensive efficacy comparable to travoprost and with a safety and tolerance profile significantly higher than travoprost.
