Usually, a pterygium is a non-cancerous growth which develops slowly over years and years. You may not want surgery unless this growth is causing discomfort or irritation. In patients who have a large or growing pterygium, a gritty, itchy, or burning sensation may be associated with a pterygium
In more severe cases, a pterygium moves into the cornea. This can distort the shape of the surface of the eye and cause astigmatism and other serious vision issues.
Causes of pterygiums
There are many factors that can lead to the development of pterygiums, but common factors include exposure to sun and ultraviolet light. People who work outdoors often or who are welders have a higher risk of developing pterygiums. Some studies have discovered evidence of viruses causing pterygiums, and there may be genetic factors as well.
Prevention of pterygiums
To prevent pterygiums from developing or growing, you can do a few things with little change to your daily life. Try to limit your exposure to the sun, especially when the sun is especially high or bright. Wear sunglasses and a hat when you are spending time outside, to lower the amount of sun you’re exposed to.
When will I require surgery for pterygiums?
Pterygiums can be removed if they are growing, cause discomfort, or leading to inflammation in your eyes. Additionally, if they become especially unsightly or threaten to impair vision, a pterygium should probably be treated with surgery.
