PURPOSE: To describe the clinical features, histopathology and treatment of ocular surface squamous neoplasia (OSSN) with intraocular tumour extension.
METHODS: Retrospective study of 23 patients.
RESULTS: The mean age at presentation of OSSN with intraocular tumour extension was 48 years. Mass (52%) and pain with redness (30%) were the most common presenting complaints. The mean duration of symptoms was 9 months. History of human immunodeficiency virus (HIV) infection was present in eight (35%) patients and one (4%) had xeroderma pigmentosum. History of prior tumour excision was noted in 16 (70%) patients. The mean basal diameter was 17 mm and the mean tumour thickness was 4 mm. Fifteen (65%) tumours had a nodulo-ulcerative tumour pattern at the time of detection of intraocular extension of OSSN. Anterior chamber cells and flare was noted in five (24%) cases and two (9%) patients had secondary glaucoma. Ultrasound biomicroscopy (UBM) (n = 11) revealed blunting of anterior chamber in three (27%) cases and uveal thickening in seven (67%) cases. Over the course of follow-up, extended enucleation (n = 6; 26%) or orbital exenteration (n = 17; 74%) was required for tumour control. At a mean follow-up period of 18 months, locoregional lymph node metastasis was seen in two (9%) patients, and one patient died with systemic metastasis. On histopathology, ciliary body was involved in all (100%) cases.
CONCLUSION: Multiple tumour recurrences with history of prior tumour excision and nodulo-ulcerative tumour pattern are commonly associated with intraocular tumour extension of OSSN. UBM is a useful tool to detect intraocular extension of OSSN.
