Primary open-angle glaucoma is the most common form of glaucoma in the United States. Typically, open-angle glaucoma has no symptoms in its early stages, and vision remains normal.
Angle-closure glaucoma – Some people are born with the iris too close to the drainage angle. These eyes, which are often small and farsighted, can develop closure of the drainage angle. Since the fluid cannot exit the eye, pressure inside the eye builds rapidly and causes an acute closed-angle attack. Chronic Angle closure occurs when the drainage angle is intermittently closed resulting in progressive damage to the optic nerve.
Secondary Glaucomas – Pseudoexfoliation and Pigment Dispersion glaucomas occur when material or pigment block the drainage channel of the eye causing the intraocular pressure to increase.
Your ophthalmologist, Eye M.D., will weigh your factors before deciding whether you need treatment. You may simply need to be monitored closely. This means your risk of developing glaucoma is higher than normal. Make sure to have regular examinations – including a baseline eye disease screening at age 40 – to detect the early signs of damage to the optic nerve.
