Glaucoma is not a singular eye disease, instead it is a term for several eye conditions that can damage your optic nerve. This optic nerve supplies visual information to your brain from your eyes. Over time, the increased pressure can wear away the optic nerve tissue, which may lead to vision loss or even blindness. If caught early, you may be able to prevent additional vision loss.
Glaucoma usually occurs when pressure in your eye increases. This can happen when eye fluid is not circulating normally in the front part of the eye. This damage leads to the field of vision having ever larger gaps, which mostly remain unnoticed at first.
