Conclusions-The finding that pilocarpine increases angular width in patients with narrow angles indicates that this agent is useful for treating patients with narrow angles and angle closure glaucoma. The prediction of the pilocarpine induced change in the angle may assist ophthalmologists in treating such patients. (Br J Ophthalmol 1999;83:553-558) Pilocarpine, one of the most commonly used and the most extensively studied antiglaucoma agents, reduces intraocular pressure by increasing aqueous outflow.
