Pterygium is a non-cancerous growth of tissue that extends from the conjunctiva (the clear tissue covering the white part of the eye) onto the cornea (the clear front surface of the eye). It often appears as a raised, triangular-shaped growth.
Pterygium surgery is typically recommended when the growth causes significant symptoms such as redness, irritation, blurred vision, or if it starts to encroach on the visual axis, obstructing vision.
Pterygium surgery involves removing the abnormal tissue growth from the surface of the eye and then grafting a healthy piece of conjunctival tissue onto the area to prevent regrowth. The procedure is usually performed on an outpatient basis under local anesthesia.
