Cosopt eye drops are useful in managing heightened pressure in the eye or ocular hypertension and open-angle glaucoma. The damage to the optic nerve due to rise in intraocular pressure persists; glaucoma can lead to permanent loss of vision. If appropriate treatment of glaucoma is not done, then it can cause complete permanent loss of sight within a few years. There are two types of glaucoma- Open-angle glaucoma and Angle-closure glaucoma.
