What is Pterygium (skin growth)?

Pterygium (pronounced ter-ridge-ee-umm) is a condition caused by sun damage where an excessive growth of tissue forms on the white part of the eye. It is usually seen when there is a history of sun exposure. Pterygium can be found on both eyes, usually on the part closest to the nose. It isn’t dangerous but should be checked properly in a full eye exam to ensure it isn’t something more sinister. It’s important to prevent further growth by wearing sunglasses and lenses with UV protection when you are outdoors.

Causes of Pterygium (skin growth)

It is not known the exact cause of pterygium; however, one reason is that excessive exposure to ultraviolet (UV) light can lead to these growths. This happens more often in individuals who reside in warm climates and spend a lot of time outside in sunny or windy conditions. Individuals whose eyes are subjected to specific factors on a consistent basis have a greater risk of developing this condition. These factors include:

  • pollen
  • sand
  • smoke
  • wind

Symptoms of Pterygium (skin growth)

A pterygium does not always trigger symptoms. If a pterygium does trigger a symptom, it is usually mild. Common place symptoms consist of redness, blurred vision, and eye irritation. You may also experience a burning sensation or itchiness. If a pterygium spreads large enough to cover up your cornea, it can affect your eyesight. Dense or bigger pterygium can also trigger you to feel like you have an external object in your eye. If you usually wear contact lenses you may not be able to do so given the discomfort from the pterygium.

How to treat Pterygium (skin growth)
