If you’re blessed with the gift of perfect or near-perfect eyesight, it can be quite jarring when you first experience a significant period of blurred vision. You’re not sure whether it’s a temporary occurrence or a sign that you might be losing your eyesight. Blurred vision refers to a lack … Read More
Glaucoma is an eye condition caused by damage to the optic nerve. It occurs when the fluid (called aqueous humor) that normally flows into and out of the area in the front of the eye fails to drain correctly. As fluid builds up, it increases pressure inside the eye. Over time, that pressure can damage the optic nerve that sends visual signals from the retina to the brain, and could potentially lead to blindness. An estimated 3 million people in the United States have glaucoma, but only about half of them are aware they have the condition.
One reason why so many Americans have not been diagnosed is that glaucoma symptoms usually don?t appear until the disease has already progressed and sight is threatened. It?s important to get familiar with glaucoma symptoms, and alert your doctor right away if you have them.
Two types of glaucoma exist. Open-angle glaucoma is the most common form. It occurs when the meshwork through which the aqueous humor normally drains out of the eye doesn?t work as well as it should. Closed-angle (or angle-closure) glaucoma is caused by a defect in the drainage system that can lead to a blockage. If the drainage angle is completely blocked, eye pressure will build at a very quick rate?fast enough to lead to blindness within one or two days if it isn?t treated.
Open-angle glaucoma symptoms usually don?t start in the early stages of the disease. As the optic nerve becomes more damaged, you might notice blank spots in your field of vision. Closed-angle glaucoma symptoms come on quickly, and can include severe eye pain, blurry vision, headache, nausea, vomiting, or halos around lights. Closed-angle glaucoma is a medical emergency. If you have these symptoms, go to a hospital or call your local emergency number right away. Doctors can save your sight with quick treatment, which usually involves creating a tiny hole to let the fluid drain and relieve pressure.
Glaucoma is an eye disease where excess pressure irreparably damages the eye, causing blindness. Because glaucoma symptoms don’t manifest until the disease is very advanced, the disease is a sneaky vision thief. Yet fewer than 10 percent of Americans surveyed know that glaucoma has no warning signs, according to the … Read More
Astigmatism, for a relatively common eye condition, is not an especially well-understood term. Simply put, it’s a condition that results when your cornea is irregularly shaped. Because of this condition, light can’t focus on the retina in the back of the eye, making it harder for you to focus on … Read More
Advancing age tends to make almost every part of the body a bit weaker and slower. Unfortunately your eyes are no exception. Aging can affect the shape of the eye and/or the functionality of its components. Refractive errors occur when the anatomy, or shape, of the eye prevents light from … Read More
