What You Should Know About Eye Drops
About Eye Drops
Eye drops, used in the treatment of glaucoma work by reducing the intraocular pressure (eye pressure) within the eyes. Increased intraocular pressure is a major risk factor for optic nerve damage. There are several classes of drops, which have different mechanisms of action. Prostaglandins, such as latanoprost, travoprost and bimatoprost reduce intraocular pressure by increasing drainage outflow from the eye. Other drop classes reduce the formation of fluid within the eye – such as beta blockers (eg timolol), alpha agonists (eg brimonidine, apraclonidine) and carbonic anhydrase inhibitors (eg dorzolamide, brinzolamide).
Eye drops are the most common form of treatment for glaucoma. Since glaucoma often has no symptoms, people may be tempted to stop taking, or may forget to take their medication/eye drops. Approximately one half of patients don’t take their glaucoma medication as prescribed, increasing the amount of visual loss caused by glaucoma. It is important that you follow your treatment plan and appointments, as recommended by your doctor. This is because glaucoma is a life-long, often progressive condition, and appropriate treatment can prevent vision loss.
