You may not notice these blind spots until most of your optic nerve fibers have died. In people with open-angle glaucoma, the fluid passes too slowly through the spongy tissue in the opening where the iris and cornea meet. Globally, it is the second leading cause of blindness after cataracts. But each type of glaucoma is different — and for some of them, experts are still learning about the causes. In this article, we will cover the causes, symptoms, and treatment of glaucoma. Congenital Glaucoma.

Open-Angle (Chronic) Glaucoma. The good news is that if a child with congenital glaucoma gets surgery soon after they are diagnosed, they have a high chance of developing good vision. This increase in pressure then damages the nerve that connects the eye to the brain (optic nerve). Open-angle glaucoma tends to run in families. Glaucoma occurs due to optic nerve damage. In fact after cataracts, glaucoma is the second most cause of blindness throughout the world.Glaucoma refers to a group of eye disease with characteristic pattern of optic nerve damage mainly due to raised pressure within the eyeball (increased intraocular pressure). The cause of normal-tension glaucoma is not fully known, but it may be related to reduced blood flow to the optic nerve due to conditions that may impair circulation. This amount is different for each person. The fluid passes through this spongy tissue as it drains out of the eye. People who already have narrow drainage angles are at higher risk of angle-closure glaucoma. It is like an electric cable made up of many small wires. Inspecting the drainage angle (gonioscopy) Angle-closure glaucoma can be chronic or acute. That leads to … Apart from structural defects, there are also a couple of syndromes … Thomas Brunner, president and CEO of the Glaucoma Research Foundation, says this research is significant. Glaucoma is relatively common, especially in older adults and can cause damage to the optic nerve if left untreated. If it does get injured then this can result in glaucoma.
