青光眼: Understanding Glaucoma and Why Early Detection Matters

青光眼, known in English as glaucoma, is a serious eye condition that can slowly damage vision without obvious early symptoms. It affects the optic nerve, which is responsible for sending visual signals from the eye to the brain. When left untreated, glaucoma can lead to permanent vision loss and even blindness. Many people are unaware they have this condition until significant damage has already occurred, which makes awareness and regular eye care extremely important.

Glaucoma is often linked to increased pressure inside the eye, known as intraocular pressure. However, some people develop glaucoma even with normal eye pressure. Age, family history, long-term steroid use, diabetes, and certain medical conditions can increase the risk. Because the condition progresses silently, people may continue normal daily activities while their peripheral vision slowly deteriorates.

There are different types of glaucoma, including open-angle glaucoma, angle-closure glaucoma, and congenital glaucoma. Open-angle glaucoma is the most common and develops gradually, while angle-closure glaucoma can occur suddenly and requires immediate medical attention. Symptoms such as eye pain, blurred vision, halos around lights, or sudden vision loss should never be ignored.

Although glaucoma cannot be cured, it can be effectively managed with early diagnosis and proper treatment. Medications青光眼, laser therapy, or surgery can help control eye pressure and slow disease progression. Regular eye examinations remain the most reliable way to protect long-term vision and maintain eye health.
