Giant ocular surface squamous neoplasia evaluated by spectral domain-optical coherence tomography

Abstract

Giant ocular surface squamous neoplasia (OSSN) is difficult to manage due to extensive surface involvement and postsurgical complications. Preoperative evaluation by spectral domain-optical coherence tomography (SD-OCT) can aid in detecting the limits in the needed tissue excision, residual corneal bed, and epithelial transition in all quadrants of the limbus. We present a case of giant OSSN managed surgically with preoperative SD-OCT evaluation for excision with margin clearance and minimal complications. The postoperative period was uneventful with a clear cornea without limbal stem cell deficiency and recurrence.
