Abstract

Surgical excision is the gold standard for the management of ocular surface squamous neoplasia (OSSN).Excision with clinically clear margins using the no touch technique and the use of double freeze thaw cryotherapy to the conjunctival edge, involved limbal zone and bare scleral bed, ensures complete removal of these lesions thus reducing the chances of recurrence. Proper orientation of the tissue on Whatman filter paper with unrolling of the margins helps the pathologist to appropriately report about the entire lesion with a critical comment on the margins and base of the tissue. Comment on the margins and base of the lesion if involved can help plan further management if required in these cases thus reducing recurrence rate. This video demonstrates these salient points to keep in mind for protocol-based excision of OSSN, handling the tissue sample and appropriate reporting by a pathologist to guide further management.
