Medical experts estimate that over 3 million Americans have glaucoma, but only half are aware they suffer from the dangerous disease. A lack of awareness and widespread misconceptions about glaucoma contribute to unnecessary loss of vision.
Glaucoma is a group of eye diseases that can cause blindness suddenly and without warning or symptoms. Many patients don’t notice any symptoms until the disease is advanced.
Glaucoma is caused by a buildup of pressure in the eye. The front of the eye serves as an elaborate drainage system for fluid that is produced within the eye and that exerts pressure on the eye. Patients with glaucoma have an inefficient drainage system, which causes elevated intraocular pressure.
That excess fluid can slowly damage the optic nerve, a bundle of more than 1 million nerve fibers in the back of the eye responsible for carrying images to the brain. Optic nerve damage causes peripheral vision to slowly reduce, often without other symptoms, until only a narrowed tunnel of vision remains. Glaucoma may also displace blood vessels that run through the optic nerve. Because the optic nerve is not capable of regeneration, the damage that occurs is irreversible and vision loss is permanent. The damage can lead to blindness.
A less common type of glaucoma, angle closure glaucoma, causes acute symptoms, including headaches, nausea, severe eye pain, redness of the eye, blurred vision, and halos around bright lights. If you experience these symptoms, go to your doctor, a clinic, or the nearest hospital immediately. Without treatment to improve the fluid flow, a person can become blind in a day or two.
To diagnose glaucoma, your doctor will take a medical history, visual acuity test, measurement of intraocular pressure with a tonometer, and a dilated eye examination. If the eye pressure is above normal or if the optic nerve looks damaged, the doctor may perform a visual field test and a pachymetry that measures the thickness of the cornea.
Gonioscopy, a simple test performed in the ophthalmologist’s office, determines if the angle is narrow and abnormal. Treatment of angle-closure glaucoma involves laser surgery to remove a small portion of the outer edge of the iris. This relieves the blocked drainage channels. Usually, surgery is successful and effective.
Other types of glaucoma may be treated with prescription eyedrops, oral medications, laser treatment, or surgery. Your doctor will discuss the best treatment plan for your specific case.
It is important to have regular eye exams to check for silent and serious conditions like glaucoma.
