Glaucoma Symptoms You Should Never Ignore What is Glaucoma? Glaucoma is a progressive eye condition that causes vision loss by damaging the optic nerve. The optic nerve acts like a vital cable, carrying visual signals from your eye to your brain so you can see. This damage is most often caused by high fluid pressure inside the eye. Normally, a natural fluid flows through the eye and drains out. If this drainage pathway becomes slowed or blocked, the fluid builds up and creates pressure. Over time, this pressure damages the sensitive fibers of the optic nerve. There are two main types of this condition: Open-angle glaucoma: The most common form, which develops very slowly over time. Angle-closure glaucoma: A less common form that happens when the eye’s drainage area narrows or becomes blocked. When dealing with glaucoma, early detection is everything. Damage to the optic nerve is permanent and cannot be reversed. However, eye doctors can do a great deal to protect your remaining sight and prevent further vision loss. Catching the disease as early as possible is the best way to preserve your independence and lifestyle. Symptoms of Glaucoma Open-Angle Glaucoma: The "Silent Thief of Sight" Open-angle glaucoma develops quietly over many years. In its early stages, it causes no pain and has no noticeable warning signs. Because your brain and your healthy eye automatically adjust to tiny blind spots, you will not notice a change in your vision until significant damage has already occurred. As the condition progresses, a patient may notice: Loss of peripheral (side) vision: This condition typically begins at the outer edges of your sight, creating a subtle "tunnel vision" effect. Because this change happens so gradually, it is rarely noticed without a doctor’s exam. Blurred vision: In the later stages of the disease, straight-ahead vision will also begin to blur. Patient Note: Because early open-angle glaucoma has zero symptoms, routine eye exams are the only way to catch it. Your doctor will use specialized tests, like a visual field test and high-tech imaging of the optic nerve, to detect changes long before you notice them. Angle-Closure Glaucoma: Acute and Chronic Acute angle-closure glaucoma occurs when the iris (the colored part of the eye) physically blocks the drainage angle, causing a rapid, dangerous spike in eye pressure. 1. Acute Angle-Closure Glaucoma This condition is a severe, sudden medical emergency. A delay of just a few hours can determine whether you preserve or permanently lose your sight. Seek immediate emergency medical care if you experience: Severe, sudden pain in the eye or forehead Seeing halos or rainbow-colored rings around lights Sudden blurry vision or rapid vision loss Extreme redness in the eye Nausea and vomiting accompanying the eye pain A severe headache If you notice these symptoms, do not wait. Please call your ophthalmologist immediately or go directly to the nearest hospital emergency room. 2. Chronic Angle-Closure Glaucoma In the chronic form, the drainage angle narrows gradually over time. Like open-angle glaucoma, it can develop without obvious early warnings. However, some patients may experience mild, occasional symptoms, including: Mild, frequent headaches or aches around the brow Brief episodes of blurred vision or seeing halos (often in dark rooms or in the evening) Mild eye redness or discomfort Who is at Risk for Glaucoma? While anyone can develop glaucoma, your risk increases significantly if you: Are over the age of 40 (with the risk rising sharply after age 60). Have a family history of glaucoma (having a parent or sibling with the condition increases your risk). Are of African, Hispanic, or Asian descent. Have medical conditions such as diabetes, high blood pressure, or poor blood circulation. Are highly nearsighted or highly farsighted. Have a history of eye injuries or long-term use of corticosteroid medications (such as steroid eye drops or pills). Have naturally elevated eye pressure. Protecting Your Sight If you fall into any of these high-risk categories, or if it has been more than a year since your last visit, please schedule a comprehensive eye exam. A standard vision screening for reading glasses cannot detect glaucoma. Your eye care professional must check your eye pressure and directly examine your optic nerve. Taking this step today is the most effective way to protect your vision for the future. How Is Glaucoma Diagnosed? A normal eye exam is not enough to tell if someone has glaucoma. A full glaucoma evaluation includes a number of specialized tests that help an ophthalmologist look at the optic nerve, check your eye pressure, and see if your visual field has changed. Some tests that are often used to diagnose glaucoma are: Tonometry (Eye Pressure Test): Intraocular pressure (IOP), which is another name for tonometry, is the pressure inside your eyes. High eye pressure is a major risk factor for glaucoma. On the other hand, some people get glaucoma even though their eye pressure is normally maintained. Optical Coherence Tomography (OCT): OCT is a painless imaging test that shows the optic nerve and the retinal nerve fiber layer in exceptional detail. It helps doctors find changes in the structure or thinning that could be signs of glaucoma. Visual Field Test: A visual field test checks your central and peripheral vision. It helps find places where you can't see as well because of damage to the optic nerve. Dilated Eye Examination: Eye drops are used to make the pupils bigger so the doctor can look at the optic nerve and other parts of the eye that are inside. Gonioscopy: Doctors can look at the drainage angle inside the eye with this test. It helps figure out what kind of glaucoma someone has by showing whether the angle is open, narrow, or closed. These tests help a glaucoma specialist get a baseline, track how the disease is getting worse, and figure out the best way to treat it. Can Glaucoma Be Treated? Damage to the optic nerve caused by glaucoma can't be fixed, but the right treatment can slow or stop further damage and help you keep the vision you already have. What kind of treatment is used depends on the type of glaucoma, how bad it is, the patient's eye pressure, and how fast the disease is spreading. Prescription Eye Drops: As a first step in treating glaucoma, prescription eye drops are often used. Either they lower the amount of fluid that is made inside the eye or they make it easier for that fluid to drain. Some people may need to take these medicines every day to keep their blood pressure in a certain range. It is very important to stick to the schedule, even if you don't feel any symptoms. Laser Treatment for Glaucoma: If you have a certain type of glaucoma, laser procedures may help the eye drain fluid better or stop it from making fluid.
