Summary
Glaucoma is an eye disease that damages the optic nerve, which is crucial for vision. It often occurs due to high pressure in the eye. Over time, this pressure can lead to vision loss or blindness if untreated. Glaucoma progresses slowly and can be managed with treatment, but it can significantly affect quality of life by impairing vision.
Glaucoma is caused by increased pressure in the eye, which damages the optic nerve. This pressure often builds up when the eye's fluid doesn't drain properly. Risk factors include age, family history, certain ethnicities, and medical conditions like diabetes. While the exact cause isn't fully understood, genetics and eye structure play significant roles.
Glaucoma often has no early symptoms, but as it progresses, it can cause vision loss, particularly peripheral vision. Some types, like angle-closure glaucoma, can cause sudden symptoms like eye pain, nausea, and blurred vision. The disease progresses slowly, making regular eye exams crucial for early detection.
Glaucoma is diagnosed through a comprehensive eye exam. Tests like tonometry, which measures eye pressure, and visual field tests, which assess peripheral vision, are used. Imaging tests like optical coherence tomography, which provides detailed images of the optic nerve, help confirm the diagnosis. Regular eye exams are essential for early detection.
Glaucoma can't be entirely prevented, but regular eye exams can detect it early. Early detection allows for timely treatment, which can prevent vision loss. Managing risk factors like high blood pressure and diabetes can also help. Protective eyewear can prevent eye injuries that might lead to glaucoma. These measures are effective in reducing the risk of developing severe glaucoma.
People with glaucoma can care for themselves by taking prescribed medications regularly and attending follow-up appointments. Lifestyle changes like a healthy diet, regular exercise, and avoiding smoking and excessive alcohol can support eye health. These actions help maintain overall health and may improve blood flow to the eyes. Managing stress and protecting eyes from injury are also important.
