Why not just remove the excess conjunctiva? Why use an amnion graft?
CCh is not caused by excessive or redundant conjunctiva. Instead it is caused by poor adhesion between the Tenon’s capsule and the sclera. Simple excision may not prevent fat prolapse and may aggravate a pinguecula, if present. Covering the bare sclera with cryopreserved amniotic membrane reinforces such adhesion without stirring up unnecessary inflammation or scarring based on the important biologic actions preserved in cryopreserved amnion grafts. These include anti-inflammation, anti-scarring, anti-angiogenesis and the promotion of healing while reducing patient pain.
