Pilocarpine eye drops are used to help lower high eye pressure in cases of glaucoma and narrow-angle glaucoma. They work by increasing the outflow of fluid from the eye, reducing internal accumulation and relieving pressure on the optic nerve. The drops help improve vision and prevent visual deterioration caused by high pressure. They also help constrict the pupil when needed for certain medical purposes. Pilocarpine drops are placed inside the affected eye after washing your hands thoroughly. You must follow your doctor's instructions carefully and not exceed the prescribed dose to ensure eye safety and achieve maximum benefit.
