I would appreciate your opinion on the cause of a pterygium in the eyes. Some say it is glare, others sand or other foreign matter in the eyes. How is this condition caused, and how do you prevent it?

  • Pterygia are wedge- or wing-shaped growths of benign fibrous tissue with blood vessels (fibrovascular), typically located on the surface of the sclera. In extreme cases, pterygia may grow onto the eye's cornea and interfere with vision.Because a pterygium resembles tissue or film growing over the eye, a person who has one may become concerned about personal appearance.As with pingueculae, prolonged exposure to ultraviolet light from the sun may play a role in the formation of pterygia.Many people with pterygia do not experience symptoms or require treatment. Some pterygia may become red and swollen on occasion, and some may become large or thick. This may cause concern about appearance or create a feeling of having a foreign body in the eye.Large and advanced pterygia can actually cause a distortion of the surface of the cornea and cause astigmatism.Sometimes people are confused about pterygia and pinguecula.
