Pterygium is a degenerative fibrovascular growth which originates from the conjunctiva (the membrane on the white part of the eye) and encroaches the cornea (the transparent tissue at the front of the eye). In the early stages, it can cause astigmatism. As it grows further, it can even cause blindness if not treated timely.
Surgery is the only option to get rid of pterygium. It is known for recurrence if the surgical technique is not good. Conjunctival autograft transplantation is a good surgical option to prevent its recurrence.
Various surgical techniques exist for the management of pterygium. Conjunctival autografting has generally been demonstrated to be superior to amniotic membrane transplantation, especially when dealing with recurrent pterygium. It is also more economical, only requiring a short additional surgical time when combined with fibrin glue application.
