Lumigan is the brand name of a medication called bimatoprost ophthalmic solution. It is primarily used to treat certain types of glaucoma and ocular hypertension, both of which are conditions that can lead to increased pressure within the eye. This increased pressure can damage the optic nerve and result in vision loss if left untreated. Lumigan belongs to a class of medications known as prostaglandin analogs. It works by increasing the outflow of fluid from the eye, thereby reducing intraocular pressure. Lowering intraocular pressure is a key goal in managing glaucoma and ocular hypertension, as it helps to prevent further damage to the optic nerve and maintain vision. Lumigan is typically administered as eye drops, and the frequency of use is determined by a healthcare professional. It's important to use Lumigan as prescribed and to follow all instructions provided by your doctor to achieve the best results and minimize potential side effects.
