Cataract- Types and Causes

Cataract- Types and Causes

Cataract is the disorder in the eye in which clouding of the lens leads to the decrease in vision. Cataract, often develop slowly and can affect one or both eyes.

Cataract is the most common cause of vision loss of people over age 40 and its symptoms may include faded colors, blurry vision, halos around light, trouble seeing at night and trouble with bright vision. Poor vision in cataract is due to aging but sometimes it may also occur due to trauma or radiation exposure. Risk factors of Cataract include diabetes, smoking tobacco, prolonged exposure to sunlight and consumption of alcohol.

Our eye lens is mostly made of water and protein but as we age, some of our protein may clump together and start to cloud a small area of the lens and this is the formation of cataract and over time, it may grow larger and make it harder to see.

Cataract can be differentiated in between the following types-  

–    A subcapsular cataract is a disorder which occurs at the back of the lens. People who are diabetic and the one who takes a heavy dose of steroid are on the greater risk of developing a subcapsular cataract.

–    A nuclear cataract is a disorder which is formed deep in the central nucleus of the lens, especially associated with aging.

–    A cortical cataract is a cataract that occurs in the lens cortex, forming a cloudy vision surrounding the central nucleus.
