Glaucoma is a group of eye diseases causing optic nerve damage. The optic nerve carries images from the retina, which is the specialized light sensing tissue, to the brain so we can see. In glaucoma, eye pressure plays a role in damaging the delicate nerve fibers of the optic nerve. When a significant number of nerve fibers are damaged, blind spots develop in the field of vision. Once nerve damage and visual loss occur, it is permanent. Most people don’t notice these blind areas until much of the optic nerve damage has already occurred. If the entire nerve is destroyed, blindness results. Glaucoma is a leading cause of blindness in the world, especially in older people. Early detection and treatment by your ophthalmologist are the keys to preventing optic nerve damage and vision loss from glaucoma..- Kellogg Eye Center

HOUSTON (FOX 26) –
Glaucoma is one of the leading causes of blindness. The problem is, it can damage your vision so gradually, you may not notice any loss of vision.
Early detection and new advances help to diagnose it. It’s a good idea to get an exam every year to check for it. If your doctor believes you have vision loss, you should consider being seen twice a year. “We test the pressure of the eye. Lower interocular pressure protects the nerve fibers, or the wire, that connects the eyes to the brain.
There is not one single cause for glaucoma. We could say high interocular pressure or high pressure in the eye causes glaucoma. The question is: what causes the pressure to be high in the first place? What I find personally is that lymphatic drainage may be blocked in the upper torso when you have glaucoma. There are other theories from chronic inflammation at the drainage system, that drains the water out of the eye, to other types of glaucoma that are related to anatomy. There are many types of glaucoma, but 90% of all glaucomas are related to pressure.
Dr. Arroyo says this is what raises your risks of glaucoma:

• African-American, Irish, Russian, Japanese, Hispanic, Inuit, or Scandinavian descent
• Over age 40
• Family history of glaucoma                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                               Read & Watch the video: http://www.myfoxhouston.com/story/29116194/detecting-glaucoma-early                                                                                                                                                                    Source: My Fox Houston
