An Overview Of Pterygium
Pterygium is a condition that causes a benign growth to develop on the protective layer of mucous membrane situated on top of the white part of your eye. In severe cases, the growth can also cover the cornea, which causes loss of vision. It's not always possible to identify the cause of pterygium, but factors that increase your risk of developing this condition include exposure to environmental irritants and allergens, damage from UV rays and being regularly exposed to windy conditions, which can dry your eyes out.
