A cataract affects the lens of the eye by clouding it thus affecting the vision.
The lens of the eye is made mostly of water and protein. The protein keeps the lens clear so that light can pass through it. The protein could clump and cloud the lens. As the cataract grows, the lens gets cloudier.
The most common cataracts develop with aging. Sometimes a secondary cataract may develop
- As a result of a surgery for other eye problems.
- Due to other health issues, such as diabetes
- Due to a trauma or eye injury.
- Congenital cataract
- Radiation cataract – due to exposure to some types of radiation
- Steroid induced cataract: chronic use steroid medications for auto-immune conditions
Cataracts are detected and diagnosed by your ophthalmologist who will plan with you an appropriate treatment
Your ophthalmologist will perform the following exams to detect possible cataracts:
- Eye chart test that measures your distance vision
- Dilated eye exam with a slit lamp microscope that allows your ophthalmologist to thoroughly examine cornea, iris, lens, retina and optic nerve for problems
Cataract symptoms:
- Cloudy vision
- Colors look faded
- Glare from lights, sun or headlights
- Trouble with night vision
- Multiple images in the eye
- Frequent change of glasses or contact lens prescription
- If you have any of these symptoms, schedule a check up with your ophthalmologist
