Pterygium Excision with Conjunctival Autograft
John Hofbauer, MD, and Nicole Fram, MD, present a case of pterygium excision in a 38-year old Hispanic male using conjunctival autograft, fibrin glue, mitomycin 0.03% and anchoring sutures. This video demonstrates the importance of careful dissection to the “root” of the pterygium rather than simply excising the pterygium flush to the plica. Subconjunctival dissection under the plica and generous tenonectomy are necessary to prevent recurrence. Four anchoring interrupted 10-0 nylon sutures are used to prevent slippage or gap of the conjunctival autograft that may occur with fibrin glue alone. Pearl: Place conjunctival autograft 1mm posterior to the limbus to avoid corneal opacity post-operatively.
