Glaucoma is a serious eye condition that develops when damage occurs to the optic nerve, often due to increased pressure inside the eye, and it can progress silently without early warning signs. In the initial stages, most people do not notice any symptoms, which makes routine eye exams essential for early detection. As the disease advances, gradual loss of peripheral vision may occur, sometimes described as tunnel vision. Blurred vision, difficulty seeing in low light, and frequent changes in eyeglass prescriptions can also appear. Understanding
What are the symptoms and causes of glaucoma is important because untreated damage is permanent and can eventually lead to blindness. The most common cause is poor drainage of fluid inside the eye, leading to elevated intraocular pressure. Other contributing factors include aging, family history, diabetes, high blood pressure, eye injuries, and long-term steroid use. In acute angle-closure glaucoma, symptoms may appear suddenly and include severe eye pain, headaches, nausea, halos around lights, and rapid vision loss. Because symptoms can vary depending on the type of glaucoma, many cases remain undiagnosed until significant damage has occurred. Early diagnosis allows doctors to slow progression through eye drops, laser treatment, or surgery. Managing overall health and attending regular eye checkups greatly reduces the risk of vision loss. Prompt treatment is key to preserving eyesight and maintaining long-term eye health.
