What may a doctor discover in the pupil before cataract develops?

A doctor may discover a condition called posterior subcapsular cataract (PSCC) in the pupil before cataract develops. PSCC is a type of cataract that forms on the back surface of the lens capsule, which is the outer layer of the lens. It is often seen in people who have diabetes, are taking certain medications (such as steroids), or have had eye surgery.

PSCC can cause a number of symptoms, including:

- Blurred vision

- Glare

- Difficulty seeing in bright light

- Double vision

- Halos around lights

If you are experiencing any of these symptoms, it is important to see an eye doctor for an evaluation. Early diagnosis and treatment of PSCC can help to preserve vision.

In addition to PSCC, a doctor may also discover other eye conditions that can lead to cataracts, such as:

- Fuchs' dystrophy: This is a condition in which the endothelial cells on the back surface of the cornea (the clear outer layer of the eye) begin to deteriorate. Fuchs' dystrophy can eventually lead to corneal scarring and cataracts.

- Pseudoexfoliation syndrome: This is a condition in which a flaky material builds up on the lens and other structures in the eye. Pseudoexfoliation syndrome can increase the risk of cataracts, glaucoma, and other eye problems.

- Uveitis: This is a condition in which the uvea, the middle layer of the eye, becomes inflamed. Uveitis can lead to cataracts, glaucoma, and other eye problems.
