Learn about the difference between Glaucoma and Cataract, the symptoms and stages of Glaucoma.
Like Cataract, Glaucoma is an eye condition that affects the elderly. However, unlike cataract, which causes blurred vision, Glaucoma is characterised by a gradual loss of vision except for the central vision.
During the early stages of Glaucoma, a patient may not experience any symptoms but in time will discover gradual loss of peripheral vision, while central vision remains clear. When Glaucoma progresses to advanced stage, peripheral vision becomes completely loss but central vision remains. However, in end stage Glaucoma, even the central vision (or at least part of it) can become lost.
Learn about the various tests used to diagnose Glaucoma including a test to measure amount of pressure within the eyeball, visual field examination and what happens when pressure within the eyeball becomes too high.
