Open-Angle Glaucoma

"Open-angle" means that the angle where the iris meets the cornea is as wide and open as it should be. Open-angle glaucoma is also called primary or chronic glaucoma. It is the most common type of glaucoma, affecting about three million Americans. -Is caused by the slow clogging of the drainage canals, resulting in increased eye pressure. -Has a wide and open angle between the iris and cornea. -Develops slowly and is a lifelong condition. -Has symptoms and damage that are not noticed.

What are normal aging changes in the sensory system?

-Crystalline lens hardens. -Loss of accommodation. -Macular degeneration. -Presbycusis -Calcification of the ossicles. -Tinnitus

Macular Degeneration

-Macular degeneration causes loss in the center of the field of vision. In dry macular degeneration, the center of the retina deteriorates. With wet macular degeneration, leaky blood vessels grow under the retina. -Blurred vision is a key symptom. -A special combination of vitamins and minerals (AREDS formula) may reduce disease progression. Surgery may also be an option.
