Glaucoma is a group of eye conditions that can cause damage to the optic nerve, resulting in vision loss or blindness if left untreated. It is often characterized by increased intraocular pressure (pressure inside the eye), but it can also occur with normal or low intraocular pressure.
The optic nerve is responsible for transmitting visual information from the eye to the brain. In glaucoma, the increased pressure or other factors lead to damage and gradual loss of nerve fibers, resulting in impaired vision.
Glaucoma typically progresses slowly and silently, and in the early stages, there are often no noticeable symptoms or pain. This makes regular eye examinations crucial for early detection.
- There are different types of glaucoma, including primary open-angle glaucoma, angle-closure glaucoma, and normal-tension glaucoma. Each type has its own characteristics and risk factors.
While there is no cure for glaucoma, early detection and treatment can help slow down or prevent further vision loss. Treatment options may include eye drops to reduce intraocular pressure, laser therapy to improve fluid drainage, or surgery in some cases. The goal of treatment is to manage the intraocular pressure and preserve the remaining vision.
Since glaucoma can progress gradually without noticeable symptoms, regular eye exams are vital for early detection, proper management, and preservation of vision.
