There are three primary forms of glaucoma: Primary Open-Angle Glaucoma (POAG), Normal-Tension Glaucoma, and Angle-Closure Glaucoma. POAG is the most common type and occurs when fluid in the eye does not drain properly, leading to increased pressure that damages the optic nerve—the nerve responsible for transmitting visual signals to the brain. Normal-Tension Glaucoma develops despite eye pressure being within the normal range, while Angle-Closure Glaucoma occurs suddenly due to blockage of fluid flow by the iris and is often accompanied by pain and redness. Symptoms of glaucoma may include vision loss, blurred or double vision, eye pain or pressure, and flashes of light. Although glaucoma-related damage is generally irreversible, treatment options such as prescription eye drops, oral medications or supplements, and, in some cases, surgery can help slow or stop disease progression. Discussing these options during annual exams or follow-up visits is essential. Regardless of severity or type, maintaining routine yearly eye appointments is crucial to preserving long-term eye health.
