A<unk> typically does not require surgery unless it grows to such an extent that it causes visual problems. Some of the symptoms such as irritation can be addressed with artificial tears. Surgery may also be considered for unmanageable symptoms. Surgery<unk> removal surgery A Cochrane review found conjunctival autograft surgery was less likely to have reoccurrence of the<unk> at 6 months compared to amniotic membrane transplant. More research is needed to determine which type of surgery resulted in better vision or quality of life. The additional use of mitomycin C is of unclear effect. Radiotherapy has also been used in an attempt to reduce the risk of recurrence. Auto-grafting Conjunctival auto-grafting is a surgical technique that is an effective and safe procedure for<unk> removal. When the<unk> is removed, the tissue that covers the sclera known as the Tenons layer is also removed. Auto-grafting covers the bare sclera with conjunctival tissue that is surgically removed from an area of healthy conjunctiva. That "self-tissue" is then transplanted to the bare sclera and is fixated using sutures or tissue adhesive. Amniotic membrane transplantation Amniotic membrane transplantation is an effective and safe procedure for<unk> removal. Amniotic membrane transplantation offers practical alternative to conjunctival auto graft transplantation for extensive<unk> removal. Amniotic membrane transplantation is tissue that is acquired from the innermost layer of the human placenta and has been used to replace and heal damaged mucosal surfaces including successful reconstruction of the ocular surface. It has been used as a surgical material since the 1940s, and has been shown to have a strong anti-adhesive effect. Using an amniotic graft facilitates epithelialization, and has anti-inflammatory as well as surface rejuvenation properties. Amniotic membrane transplantation can also be fixated to the sclera using sutures, or glue adhesive. Amniotic membrane by itself does not provide an acceptable recurrence rate.
