Glaucoma is a condition that damages your eye’s optic nerve which transmits images to your brain. It’s the result of high fluid pressure, called intraocular pressure, inside your eye. This happens when the liquid in the front part of the eye doesn't circulate the way it should. If the damage continues, glaucoma can lead to permanent vision loss. Without treatment, glaucoma can cause total permanent blindness within a few years.
The treatment recommended by specialized ophthalmologists much depends on the type of glaucoma (open-angle and narrow angle glaucoma), but the options are eye drops – to reduce the pressure in the eyes, laser treatment – to open up the blocked drainage tubes or reduce the production of fluid in the eyes and surgery – to improve the drainage of fluid.
