What causes “Pterygium”?
Pterygium is an eye disease that may occur after pinguecula. It usually appears as a white, yellow, or pink, triangular-shaped plaque that forms on the conjunctiva extending into the cornea. Although pterygium rarely causes any problems and may not require treatment, if the pterygium grows large or thickens and blocks the cornea, surgery may be required to remove it, as it can affect the patient’s vision.
Causes of pterygium
Although the exact cause of pterygium is still unknown, there are several risk factors that may be involved, especially those who are exposed to the sun’s ultraviolet radiation for a long time, those who have dry eyes, and those who are irritated by wind, dust, smoke, pollution or sand, such as those who work outdoors, farmers, fishermen and those who live near the equator. ยูฟ่าเบท Pterygium usually occurs in males between the ages of 20 and 40, and those who have fair skin or light-colored eyes may also be at risk of developing pterygium.
Who gets pterygium (surfer’s eye disease)?
Surfers do get pterygia (the plural of pterygium) more often. But anyone can get one if they spend a lot of time outdoors without eye protection. It’s more common in older adults, who’ve had more exposure to the elements over time, and also in those who live near the equator, where sunlight is more intense.
How serious is a pterygium?
A pterygium isn’t an invasive growth. It’s not cancerous, and it won’t spread to other nearby tissues. But it can continue to grow across the surface of your eye. If it reaches your cornea (the clear part that covers the colored part), it can damage your vision. In this case, you might need surgery to remove it.
