A 62-year-old white man with a long history of sun exposure was referred to the Duke Eye Center after his ophthalmologist detected a spot on his left eye during routine observation. At Duke, ophthalmologist Gargi Vora, MD, examined the patient and determined that the spot was suspicious for ocular surface squamous neoplasia (OSSN; Figure 1).
Question: What noninvasive approaches did Vora employ to confirm the diagnosis and treat the OSSN?
