Hypertensive retinopathy is retinal vascular damage caused by hypertension. Symptoms usually do not develop until late in the disease and include blurred vision or visual field defects.Treatment is directed at controlling blood pressure and treating the retina when vision loss occurs.	Diabetic retinopathy is a diabetic condition that affects the eyes. It's caused by damage to the blood vessels of the light-sensitive tissue at the back of the eye (the retina). Af first, diabetic retinopathy may cause no symptoms or only mild vision problems. Eventually, it can cause blindness. The condition can develop in anyone who has type 1 or type 2 diabetes. The longer you have diabetes and the less controlled your blood sugar is, the more likely you are to develop this eye condition.	Glaucoma is a group of eye conditions that damage the optic nerve, which is vital for good vision. The damage is often caused by an abnormally high pressure in your eye. Glaucoma is one of the leading causes of blindness. The effects of glaucoma come with no warning signs until the condition is at an advanced stage. Because vision loss due to glaucoma can't be recovered, it's important to have regular eye exams that diagnose it in its early stages.
Macular Degeneration is the leading cause of vision loss, affecting more than 10 million Americans -- more than cataracts and glaucoma combined. It is considered an incurable eye disease. Macular Degeneration is caused by the deterioration of the central portion of the retina. The biggest risk factor for Macular Degeneration is age (55 and older being most at risk), but other factors include UV rays, genetics, race, and smoking.	A pterygium, also known as "surfer's eye," is an elevated, wedged-shaped bump on the eyeball that starts on the white of the eye and can invade the cornea. Being in bright sunlight for long hours--especially when you are on water, which reflects the sun's harmful UV rays--increases your risk. Pterygia are non-cancerous growths, but they can permanently disfigure the eye, causing discomfort and blurry vision.	A cataract is a clouding of the lens in your eye that affects your vision. Cataracts are very common in older people. By age 80, more than half of all Americans either have a cataract or have had cataract surgery. Cataracts usually develop slowly. Common symptoms are blurry vision, colors that seem faded, glare (seeing halos around light), not being able to see at night, double vision, & frequent prescription changes. Wearing sunglasses and a hat to block UV sunlight may help to delay cataracts.
