Eye Diseases, Part 3

Cataracts

A cataract is a clouding of the eye’s normally clear lens, which leads to a progressive blurring or dimming of vision. It is the world’s leading cause of treatable blindness and among the most common conditions related to aging – by age 65, you have a 50 percent chance of developing a cataract, and, by age 75, it jumps to 70 percent.

A cataract starts out small and initially has little or no effect on vision. As the cataract progresses, it becomes harder to read and perform other normal tasks. In the early stages, your doctor may recommend stronger eyeglasses and adjusting your lighting to reduce glare. When cataracts disrupt your daily life, your doctor may recommend cataract surgery, which is one of the most frequent and successful procedures done in the U.S.

Iritis/ Anterior Uveitis

Iritis is an inflammation of the iris and the adjacent tissue known as the ciliary body. It can be related to trauma, underlying inflammatory or autoimmune disease, or can be idiopathic. Symptoms include a red painful eye and sensitivity to light. It is treated with anti-inflammatory and dilating eye drops. When not treated, it can lead to more extensive and even permanent damage.
