Glaucoma

This progressive disease damages the optic nerve, which carries visual information from your eye to your brain, usually because of increased pressure inside the eye. From the outside, there are no visible signs, and your eyes look completely normal, which is why it’s often called the “silent thief of sight.” The harm happens internally and gradually, affecting peripheral sight first before moving to central vision if left untreated. Early detection through regular comprehensive exams is crucial, because by the time you notice changes, significant irreversible loss has already occurred.

Glaucoma develops when fluid in the front part of your eye doesn’t drain properly, leading to increased intraocular pressure that damages the optic nerve over time. In primary open-angle glaucoma, the drainage system becomes less efficient gradually, while angle-closure glaucoma occurs when the iris blocks the drainage angle partially or completely. Risk factors include age over 60, family history, certain medical conditions like diabetes and high blood pressure, previous eye injuries, and prolonged use of corticosteroid medications. Some people develop glaucoma even with normal eye pressure, indicating other factors, like poor blood flow to the optic nerve, may contribute to the disease.

Yes, glaucoma has a strong hereditary component, and having a family history significantly increases your risk of developing the disease. If you have a parent or sibling with glaucoma, your risk is four to nine times higher than someone without a family history. The genetic link is particularly strong for primary open-angle glaucoma, the most common form of the disease. This is why we strongly recommend regular comprehensive eye exams if glaucoma runs in your family, ideally starting in your 30s or 40s rather than waiting until you’re older or notice symptoms.

Glaucoma cannot be cured, but it can be successfully managed and controlled to prevent further vision loss when detected early and treated consistently. The goal of all glaucoma treatments, whether eyedrops, laser procedures, or surgical implants, is to lower eye pressure and protect the optic nerve from additional damage. Any vision loss that has already occurred before treatment cannot be restored, which is why early detection is so critical. With proper management through regular monitoring every four to six months and appropriate treatment, most people with glaucoma maintain functional vision throughout their lives.

While you cannot completely prevent glaucoma, especially if you have genetic risk factors, you can take steps to catch it early and reduce your risk of progression. Get comprehensive eye exams regularly, every one to two years if you’re over 40, annually if you have risk factors, and every four to six months if you’ve been diagnosed. Maintain a healthy lifestyle with regular exercise, which can help lower eye pressure naturally, and protect your eyes from injuries by wearing appropriate safety eyewear. Control underlying health conditions like diabetes and high blood pressure, avoid smoking, and limit caffeine intake, as these factors can affect your eye pressure and overall eye health.
