Pterygium Surgical Treatment
Pterygium surgery is a procedure performed to remove noncancerous conjunctiva growths (pterygia) from the eye. The conjunctiva is the clear tissue covering the white part of the eye and the inside of the eyelids. Some cases of a pterygium produce little to no symptoms. Severe overgrowth of conjunctiva tissue can cover the cornea and interfere with your vision.
Symptoms:
For some, pterygium causes no symptoms other than appearance. However, an enlarged pterygium may cause redness and inflammation. Should a pterygium grow into the cornea, the clear, outer layer of the eye, it can distort the shape of the cornea causing a condition called astigmatism or lead to corneal scarring.
Symptoms of pterygium may include: Burning / Gritty feeling / Itching / Sensation of a foreign body in the eye / Blurred vision.
Causes:
The exact cause of pterygium is unknown; however, it is associated with excessive exposure to wind, sunlight and sand. This condition is found in much greater numbers among people who live close to the equator, but it can develop in anyone who lives in a sunny climate. Pterygium is most common in young adults ages 20 to 40 and appears to be more common in men than women.
Treatment Options :
If symptoms are mild, pterygium usually doesn’t require treatment. If pterygium worsens and causes redness or irritation, it can be treated with some form of eye drops. These could be lubricating or steroid eye drops.
If the lesion causes discomfort or interferes with vision, it can be surgically removed in an outpatient procedure. In the past, doctors were reluctant to recommend surgery due to patient discomfort and high recurrence rates. But recent techniques offer patients a very comfortable procedure with low rates of recurrence. Consider whether surgery is right for you, based on the size of the pterygium and the presence of chronic redness or irritation. Surgery might also be an option if the pterygium prevents you from wearing contact lenses or is causing astigmatism.
