Surgically induced necrotizing scleritis after pterygium excision and conjunctival autograft
Abstract
To report a case of surgically induced necrotizing scleritis (SINS) after pterygium excision and conjunctival autograft. A 55-year-old man presented 2 weeks after excision of primary pterygium with conjunctival autograft in the right eye with severe pain in that eye. He had undergone cataract surgery in that eye 8 months before. The graft was pale and white. The underlying sclera was white and avascular. There was marked inflammation adjacent to the site of surgery and graft. A scraping from the graft surface revealed no organisms in smears, and culture revealed no growth. The conjunctival graft was removed. Amniotic membrane transplantation was performed. After surgery, the amniotic membrane was avascular and pale. Systemic steroid therapy was initiated. Three days after initiation of systemic steroid therapy, the graft became vascularized. Over the next 10 days, the eye quietened, conjunctival and scleral inflammation lessened, and the graft was well accepted. Surgically induced necrotizing scleritis is a rare complication of pterygium excision with conjunctival autograft. A pale graft with underlying avascular sclera and surrounding inflammation should arouse suspicion of this complication.

Allogenic & Autologous Therapies
Allogenic therapies are generated in large batches from unrelated donor tissues such as bone marrow. In contrast, autologous therapies are manufactures as a single lot from the patient being treated. Here is the latest research on allogenic and autologous therapies.
