What is Cosopt?
Cosopt drops are a combination of Timolol Maleate and Dorzolamide Hydrochloride that are used to treat open-angle glaucoma and ocular hypertension. It reduces the amount of fluid produced in the eye which lowers the pressure.
High pressure inside the eye can lead to blindness. Ocular hypertension can occur when fluid does not pass through the eye as effortlessly as it enters it. Loss of sight can be gradual so early detection is important. Loss of sight may not be noticeable so regular eye exams are crucial.
