Understanding open-angle glaucoma
Open-angle glaucoma is an eye disease in which pressure inside the eye can gradually damage the optic nerve, the nerve that carries images from the eye to the brain. It is the most common form of glaucoma in the United States; according to the National Eye Institute, "9 in 10 people with glaucoma have the open-angle type." The National Eye Institute explains that experts aren't sure what causes open-angle glaucoma, but pressure may build up when fluid in the eye can't drain fast enough. Early on there are usually no symptoms; MedlinePlus notes that "most people have no symptoms" and that vision loss typically begins slowly with side (peripheral) vision. A comprehensive dilated eye exam, including tonometry to measure eye pressure and a visual field test, is used to detect it. Treatment can slow or stop progression but cannot restore lost sight or cure the disease. As the National Eye Institute states, "there's no cure for glaucoma, but early treatment can often stop the damage and protect your vision." This is general information, not medical advice; treatment decisions should be made with a qualified eye care professional.
First-line treatment
The shared goal of all first-line treatment is to lower intraocular pressure (IOP). Per the American Academy of Ophthalmology (AAO) Primary Open-Angle Glaucoma Preferred Practice Pattern, "clinical trials have shown that lowering IOP reduces the risk of developing POAG and slows the progression of POAG," and "a reasonable initial treatment goal in a patient with POAG is to reduce IOP 20% to 30% below baseline," adjusted by disease course and severity. The AAO notes that "effective laser surgical, medical, and incisional surgical approaches exist for lowering IOP." In practice, the National Eye Institute states that "prescription eye drops are the most common treatment," while the AAO reports that selective laser trabeculoplasty can be considered "an effective and safe alternative to medications as a first-line treatment for primary open-angle glaucoma." A clinician individualizes the choice.
