Abstract
Evaluation of Sutureless Glueless Conjunctival Autograft in Pterygium Surgery
Highlights
A pterygium is a wing-shaped corneal incursion of an aberrant conjunctival wound healing response, characterized by the centripetal growth of an altered squamous epithelium with goblet cell hyperplasia and an underlying stroma of activated proliferating fibroblasts, neovascularization, inflammatory cells, and extracellular matrix
Limbal-conjunctival autograft is currently the most popular surgical procedure as it has been suggested that including the limbal stem cells act as a barrier to the conjunctival cells migrating onto the corneal surface.[2]
All cases had been operated with conjunctival autografts taken from superior bulbar conjunctiva
Summary
A pterygium is a wing-shaped corneal incursion of an aberrant conjunctival wound healing response, characterized by the centripetal growth of an altered squamous epithelium with goblet cell hyperplasia and an underlying stroma of activated proliferating fibroblasts, neovascularization, inflammatory cells, and extracellular matrix. Limbal-conjunctival autograft is currently the most popular surgical procedure as it has been suggested that including the limbal stem cells act as a barrier to the conjunctival cells migrating onto the corneal surface.[2]. The newest approach is autoblood graft fixation, a technique known as suture- and glue-free autologous graft. The operative time is prolonged and there are exaggerated postoperative symptoms of eye irritation, tearing, redness, foreign body sensation.[3]. The use of glue can take care of these problems, but the cost, availability and associated potential risks are constant problems.[4]
