Why Are My Eyes Red?
3. Glaucoma
Glaucoma is a group of conditions that causes damage to the optic nerve that results in loss of vision. It can be generally categorized into open angle, closed angle, and normal tension glaucoma. Symptoms may vary depending on the type of glaucoma. For example, in open angle glaucoma, there is no pain and it first affects peripheral vision followed by a decrease in central vision. Left untreated, it results in blindness. In closed angle glaucoma, there can be severe eye pain, nausea, redness in the affected eye, and blurry vision.
This subtype of glaucoma also results in permanent vision loss. Early treatment delays or stops the disease progression. Treatment options include medication, laser, or surgery to decrease pressure in the eye. Closed angle glaucoma is considered a medical emergency.
