A pterygium, from the Greek word for "wing," is an abnormal growth of tissue that extends from the conjunctiva (a membrane that covers the white of the eye) onto the cornea. Pterygia may be small, or grow large enough to interfere with vision and cause irritation. These growths are commonly located on the inner corner of the eye.
Symptoms
Appearance of a raised pink, white, or red lesion on the eye
Redness and irritation of the eye
Foreign body sensation
Decreased or blurry vision
The symptoms described above may not necessarily mean that you have a pterygium. However, if you experience one or more of these symptoms, contact your ophthalmologist for a complete exam.
