Statistics show that glaucoma is the second leading cause of blindness worldwide, so the earlier it’s diagnosed, the better. Once diagnosed, appropriate treatment can minimize, or even prevent, optic nerve damage and reduce vision loss due to glaucoma. Glaucoma can impair your vision so slowly that loss of vision may not even be noticed until the disease is at an advanced stage. Primary open-angle glaucoma is the most common type of glaucoma, and often has no noticeable signs or symptoms. With this in mind, it’s very important to get your eyes examined regularly with our optometrist in Arlington. Our dedicated staff, are well-educated to evaluate, diagnose, and treat glaucoma.
Caused by various eye issues that result in gradual vision loss, glaucoma is caused by damage to your optic nerve. Even though high pressure on the eye is a cause of glaucoma, it can also occur in the presence of normal eye pressure. The two main types of glaucoma in adults are primary open-angle glaucoma and closed-angle glaucoma. Open-angle glaucoma is the more common of the two forms and happens when the pressure inside your eye rises because of fluid back-up. In time, pressure builds up, the optic nerve gets damaged, and the result is permanent vision loss. Closed-angle glaucoma is more rare and happens when the drainage canals of your eye get blocked, causing a fast rise in pressure inside your eye. Our optometrist in Arlington recommends that those at high risk for glaucoma should have a dilated pupil eye exam at least every two years. Our specialists use several tests to detect glaucoma and these tests are much more thorough and reliable than what is known as a glaucoma screening.
Our optometrist in Arlington wants our patients to know there is a difference between a glaucoma diagnostic screening and a comprehensive eye exam at Heritage Eye Care. For the most part, glaucoma screenings have been somewhat ineffective in detecting the disease. Unintentionally, they may also stop people from having a proper eye exam that will show full and specific results. The intention of a glaucoma screening is to identify those with glaucoma who may not be under the care of an optometrist, though we know through research, screening processes do not meet published quality standards. A general screening may very well detect glaucoma, but they are simply not inclusive enough to show other eye conditions that could be serious. If other eye conditions are present, such as refractive error, cataracts, and diabetic retinopathy, they need to be diagnosed and treated by an optometrist as soon as possible.
