Abstract

SIGNIFICANCE: Ocular surface squamous neoplasias are superficial tumors of the cornea and conjunctiva that can be sight threatening if neglected. Therefore, accurate noninvasive diagnostic modalities are needed. PURPOSE: The purpose of this case series was to describe the hallmark features of ocular surface squamous neoplasia on high-resolution optical coherence tomography (HR-OCT) imaging and its use in the evaluation and management of superficial ocular tumors. CASE SERIES: Five eyes of four patients with ocular surface squamous neoplasia are described.Whereas two eyes displayed the classic clinical features of ocular surface squamous neoplasia, three of the five eyes hadmore subtle atypical features. However, all shared features onHR-OCT of epithelial thickening and hyperreflectivity with abrupt transitions between normal and abnormal tissue, classic features of ocular surface squamous neoplasia. All lesions ultimately underwent incisional or excisional biopsy and were confirmed to be ocular surface squamous neoplasia on histopathology. CONCLUSIONS: Ocular surface squamous neoplasia may present as a classic tumor but can also have subtle features ormasquerade. Accurate methods to diagnose andmanage patients with ocular surface squamous neoplasia are necessary.With recent advancements in technology, HR-OCT has been demonstrated to accurately identify ocular surface squamous neoplasia with the repeatable optical findings of (1) epithelial thickening, (2) epithelial hyperreflectivity, and (3) abrupt transition zone between normal and abnormal tissue. This case series demonstrates how HR-OCT can help provide an optical biopsy to guide appropriate diagnosis and management of this neoplastic lesion.
