Latanoprost 0.005% versus bimatoprost 0.03% in primary open-angle glaucoma patients

This study indicates that the 24-hour diurnal IOP is statistically lower in POAG with bimatoprost, compared with latanoprost, among patients who tolerated bimatoprost. However, the IOP difference between groups was small and may not be clinically meaningful. In contrast, conjunctival hyperemia seems statistically greater with bimatoprost. The exact clinical importance of conjunctival hyperemia, if any, needs to be clarified further.
