Anterior Segment OCT in Ocular Surface Lesions
AAO 2019 Video Program
Ocular Pathology/Oncology
Because not all ocular surface tumors have classical features at presentation, establishing an accurate diagnosis without histopathology is challenging. Anterior segment OCT (AS-OCT) is a useful tool for the diagnosis of ocular surface tumors, including detection of subclinical disease. It is also useful for disease monitoring during the follow-up period. The unique AS-OCT features of various ocular surface tumors help in distinguishing benign from malignant tumors. In this video, we discuss the general principles of AS-OCT and describe the AS-OCT features of common ocular surface tumors via case illustrations. Various tumor descriptions will include ocular surface squamous neoplasia, pseudoepitheliomatous hyperplasia, conjunctival nevus, primary acquired melanosis and other ocular surface tumors.
