A pterygium is a fleshy triangular area of tissue, usually on the inner corner of the eye, that can also grow onto the cornea. Sometimes, it extends toward the center of the cornea so that it interferes with vision. As the pterygium develops, it may warp the cornea, causing astigmatism.
Symptoms of a Pterygium:
- Visible tissue growing over the eye
- Irritation of the eye
- Redness localized in the corner
- Possible blurred vision

Diagnosing a Pterygium:

Treatment of a Pterygium:
Eye drops or ointment can be used to reduce the irritation caused by a pterygium. If the pterygium grows toward the central cornea, it often needs to be removed surgically. Outpatient surgery is very successful. Dr. Mark Sczepanski has great success with some new surgical techniques and medication that greatly reduce the risk of recurrence of the growth.
