What is a pterygium?
A pterygium is a lesion that begins on the conjunctiva of the eye, appearing as a small, fleshy growth. When it extends over the cornea, it is referred to as a true pterygium.
The lesion grows across the surface in a triangular shape, advancing onto the cornea and causing decreased vision. A true pterygium firmly adheres to the surrounding ocular structures.
Who is most commonly affected?
People who spend long hours working under the sun without ultraviolet (UV) protection are at greater risk of developing pterygium.
What are the symptoms of pterygium?
The most common symptoms include burning sensation, itching, and dryness of the eye. In advanced cases, the pterygium may grow toward the center of the cornea, blocking the passage of light and causing a significant decrease in vision.
How can pterygium be treated?
Early stages: Symptoms such as mild burning or dryness can be managed with lubricating eye drops and vasoconstrictors.
Advanced stages or cosmetic concerns: Surgery may be required to remove the pterygium and replace it with healthy conjunctival tissue.
