Pterygium is a common eye disorder which is commonly known as "angel's wing". It is quite common in the climate zone of Turkey. Usually forming on the side of the conjunctiva closest to the nose and extending to the corneal tissue that covers the eye's colored part, it is a wedge-shaped, pink, non-cancerous lesion which gradually grows. Also termed as "surfer's eye", pterygium more often occurs in people who spend long hours outdoors, are exposed to too much sunlight and dry air current and work especially long hours or do sports under the sun without protection, that is without wearing sunglasses or a hat. Its symptoms include burning, itching, discomfort, the sensation that there is a foreign body in the eye and blurred vision.
