Pterygia is the noncancerous growth of conjunctiva in the eye. This tissue is removed through
Pterygium surgery. The conjunctiva is the covering tissue of sclera and inside the eyelids, which is normally clear. Mild cases of a pterygium have little or no symptoms. However, in Severe cases, the overgrown conjunctiva tissue can spread to the cornea and occupy the pupil which impairs vision and causes astigmatism. This overgrowth makes the eye feel dry and irritated with a foreign body in it. On another hand, it has cosmetic effects as well. Common symptoms of pterygium are:
•Redness of the eye
•Sensing burning and itching
•Discomfort when using contact lenses
In rare cases, corneal scarring which should be treated before causing vision loss.
Some cases of a pterygium produce little to no symptoms. Severe overgrowth of conjunctiva tissue can cover the cornea and interfere with your vision.
If the pterygium is large enough, seeing can be difficult. It also can make the patient feel that their eye is irritated, dry, or has something in it. It also can cause cosmetic concerns. In some people, the pterygium grows to cover the entire front of the eye and makes it hard to see.
When the pterygium causes discomfort to the patient or enlarges its size to the extent that it approaches or occupies the area of the pupil, causing astigmatism or impairing vision, surgery is necessary.
So, if you have the following symptoms, surgery is inevitable:
•Symptomatic conjunctiva overgrowth
•Red and inflamed, and large, thick lesions
•Persistent sensation of a foreign body in the eye
•Blurry vision caused by problematic lesions of pterygium
There are two types of tissue graft that are used to replace the removed area in pterygium surgery:
1.Conjunctival autograft (CAG): conjunctival tissue will be removed from another part of the eye to cover the bare spot of removed pterygium.
2.Amniotic membrane transplant (AMT): amnion tissue from a baby’s placenta after childbirth is obtained from the tissue bank to cover the bare spot.
