Pterygium requires eye surgery when a patient experiences continual discomfort and impaired vision, or the size and appearance of the lesion dictates its removal, according to WebMD. Doctors usually perform surgery to remove lesions on an outpatient basis. Mild pterygium symptoms typically do not require treatment.
Pterygium is a pink, fleshy, noncancerous growth on the sclera of the eye, explains WebMD. Generally, the growth is not a serious health concern. In some cases however, a lesion can grow to cover the eye's pupil and impair vision. If the growth become inflamed, ointments or eyedrops can help to lubricate the area temporarily. Vasoconstrictor or steroid eyedrops can also provide short-term relief.
