Pterygium is a pink, fleshy growth of tissue on the white of the eye, usually forming on the side of the eye closest to the nose. Pterygium is a relatively common eye condition and most often affects those who spend a lot of time outdoors, especially on beaches or swimming. Pterygiums are caused by prolonged exposure to sunlight or UV rays, dry eyes, and regular outdoor eye irritants such as dust or sand. While this growth tends to appear on only one eye, in some cases it may develop on both.
In addition to its physical appearance, the presence of a pterygium can cause blurred vision, itchiness, a burning sensation, and the perpetual feeling that something is stuck in your eye.
If the pterygium is relatively small or only causing mild discomfort, a prescription of medication and eye drops may be sufficient. If the growth has been left untreated for a long period of time or has grown to a size whichis causing difficulty seeing, the pterygium can be removed surgically by what is known as a pterygium removal procedure.
Please note, that unless examined by an eye care professional, pterygiums can sometimes be mistaken as a pinguecula.
