High resolution anterior segment optical coherence tomography of ocular surface lesions: a review and handbook

Abstract

ABSTRACT Introduction: High-resolution anterior segment optical coherence tomography (HR-OCT) has revolutionized the way by which clinicians can diagnose and differentiate ocular surface lesions. Careful interpretation of HR-OCT images can provide morphological information about the lesion of interest and help guide the diagnosis. Areas covered: This paper reviews the steps to interpreting HR-OCT images of ocular surface lesions and summarizes their characteristic findings. Expert opinion: Among the multiple modalities available to image the ocular surface and anterior segment, HR-OCT has emerged as an instrumental tool to obtain ‘optical biopsies’ of various ocular surface lesions. A step-by-step approach to acquiring and interpreting HR-OCT images can allow for accurate in-office characterization and diagnosis of both benign and malignant ocular surface lesions.
