Types of Glaucoma

Glaucoma is a group of eye disorders that cause damage to the optic nerve, which is responsible for carrying visual information from the eye to the brain. It is often caused by an increase in the intraocular pressure of the eye, which can be caused by a number of different factors. There are several types of glaucoma, including open-angle, angle-closure, normal-tension, congenital and secondary glaucoma. Each type has its own unique characteristics, but all can result in irreversible vision loss if left untreated. Glaucoma is the second leading cause of blindness in the world and is most common in those over the age of 60. It is important to be aware of the signs and symptoms of glaucoma, and to seek treatment as early as possible to prevent vision loss.
