Topics: Conditions and Diseases : Glaucoma

Glaucoma is a group of conditions that cause damage to the optic nerve and lead to a gradual loss of vision and, if not treated, blindness. Some types of glaucoma happen when the fluid in the eye doesn't drain quickly enough or when a blockage stops the fluid from draining and pressure builds up in the eye. In some cases, the fluid drains properly, but there is still too much pressure on the optic nerve.
