￼ Glaucoma damage may be caused by raised eye pressure or a weakness in your optic nerve. Or you may have an eye pressure within normal limits but the damage occurs because there is a weakness in your optic nerve. In most cases, high pressure and weakness in the optic nerve are both involved to a varying extent. (Eye pressure is not connected to your blood pressure.)
Different Types of Glaucoma
There are four main types of glaucoma:
▪ Primary open angle glaucoma (POAG) also known as chronic glaucoma. ▪ Acute angle closure glaucoma. ▪ Secondary glaucoma. ▪ Developmental glaucoma. More than three million Americans are living with glaucoma, 2.7 million of whom-aged 40 and older-are affected by its most common form, open-angle glaucoma.
Glaucoma is a leading cause of irreversible blindness in the United States and the world.
