Glaucoma is the second leading cause of blindness in the world, and belongs to a group of eye diseases that damage your optic nerve, inside your eyes, potentially causing preventable blindness. It is estimated that half of more than 4 million Americans with glaucoma do not even realize they have it.
When fluid inside the eye does not drain properly, it can lead to excess pressure intraocular pressure and increase risk of getting glaucoma. Other sources of increase intraocular pressures include aqueous miss direction and or over production of aqueous fluids without adequate drainage. The elevated pressure can damage nerves and the blood vessels in the eye negatively affect vision.
Treatment of open-angle glaucoma requires lowering the eye's pressure by increasing the drainage and or production of aqueous humor. Medications both topical drops and oral pills can accomplish both of these goals. With open-angle glaucoma, there may be no obvious symptoms of this eye disease at all until the condition is very advanced and when there is significant vision loss.
