Alyscia F. Monaco Unit 9 Assignment 2 05/15/2015 The Aging Special Senses Glaucoma is a condition that causes damage to the eye's optic nerve and gets worse over time. It's often associated with a buildup of pressure inside the eye. Glaucoma tends to be inherited and may not show up until later in life. The increased pressure, called intraocular pressure, can damage the optic nerve, which transmits images to the brain. If damage to the optic nerve from high eye pressure continues, glaucoma will cause permanent loss of vision. Without treatment, glaucoma can cause total permanent blindness within a few years. Because most people with glaucoma have no early symptoms or pain from this increased pressure, it is important to see the eye doctor regularly so that glaucoma can be diagnosed and treated before long-term visual loss occurs. Retinal detachment is a very serious eye condition that happens when the retina separates from the tissue around it. Since the retina can't work properly under these conditions, you could permanently lose vision if the detached retina isn't repaired promptly. The possible risks for retinal detachment include being severely nearsighted, having had an eye injury or cataract surgery, family history of retinal detachment. Symptoms of retinal detachment include flashes of light, seeing "floaters" (small flecks or threads), darkening of your peripheral (side) vision. There are many ways to reattach a retina which include laser (thermal) or freezing (cryopexy), Pneumatic retinopexy, Scleral buckle, and Vitrectomy. Depending on the complexity of the retinal detachment, various combinations of vitrectomy, buckle, laser and gas bubble may be used to repair the retina. Ataxia describes a lack of muscle control during voluntary movements, such as walking or picking up objects. A sign of an underlying condition, ataxia can affect movement, speech,
