Why pilocarpine is contraindicated in narrow-angle glaucoma?
Pilocarpine is also contraindicated in uveitis and secondary glaucoma because its miotic effect may predispose to posterior synechiae and pupillary occlusion. A frequently observed side effect after prolonged use is conjunctival hypersensitivity which warrants dilution of the pilocarpine or discontinuance of this drug.

Why is pilocarpine used for angle closure glaucoma?
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.
