What is cataract in children?
A dark area around the lens, located behind eye iris is what is known as a cataract. Approximately one in every 200 is estimated to develop cataract at an early age. A genetic disorder can contribute to the formation of these cataracts, although testing should be done to determine the root cause accurately. Click this link to find out more »
A standard lens will be clear to allow passage of light for clear image focusing on the retina. A cataract formation causes scattering of the light rays when they are passing the cloudy lens; thus, the image formed is distorted and blurred.

- Steroid use
- Childhood ailments, such as rheumatoid arthritis
- Complications from eye disorders, such as glaucoma
Bilateral cataracts are those cataracts that develop in both eyes while unilateral cataract develops in one eye. The causes of the bilateral cataracts are not known though genetic disorders should be tested to determine if it is a hereditary disorder. Unilateral cataracts are usually as a result of multiple causes, not a particular disease. Trauma can also play a significant role in the development of unilateral cataracts.
