What is Pterygium?
Pterygium surgery involves removing the abnormal tissue from the cornea and sclera of the eye. Modern methods are more successful than conventional methods. Those most likely to be affected are smokers, persons exposed to UV light, dust, dirt, wind, dryness, and smoke during outdoor activities, such as sports. Improvement of risk factors can reduce recurrence rates.
What is a pterygium?
There are two primary types of pterygia (pronounced te-ri-gi-ums): a triangular shaped lump of tissue that originates from the conjunctiva (the thin membrane covering the white of the eye) and grows onto the cornea (clear central section of the eye). Pterygiums can occur in both eyes, usually on the nasal side of the eye.
- Pinguecula – A pinguecula is a white, yellow, or fleshy spot with vessels on the conjunctiva that has not yet grown over the cornea. There is no treatment. Additionally, we recommend wearing sunglasses and taking antioxidant eye vitamins. To make sure it doesn’t grow, we recommend taking vitamins.
- Pterygiums – Pterygiums are white or fleshy patches with blood vessels that grow over the cornea. Flat or raised, they can be painful. At this point, they must be surgically removed.
- Pterygium – When the pterygium is large, it can also affect the quality of vision, as it changes the shape of the cornea and can grow to cover the pupil. After it is removed, a residual scar can sometimes be seen. The best result is achieved with early surgery.
What causes a Pterygium?
It is unknown what causes Pterygia, but exposure to ultraviolet radiation and hot, dry environments is strongly associated with them. People who spend a lot of time outdoors, like farmers and surfers, are more likely to develop Pterygiums in the northern parts of Australia.
Can the Pterygium grow back?
Despite surgical removal, Pterygium can return. It is common for a recurrent Pterygium to grow more rapidly than an initial Pterygium. While our professionals will use the best treatment to prevent the recurrence of the Pterygium, it is impossible to predict the risk of this happening in any particular case. A regrowth may occur in one out of ten patients.
How can a Pterygium be prevented?
Protecting your eyes from UV light is the best way to prevent the development of Pterygiums. UV radiation can also cause cataracts and other eye conditions, as well as the development of skin cancer. During the hours of 10am and 2pm, you should reduce your sun exposure. In addition, wraparound sunglasses and a hat can also help.
