Purpose: To report a rare case of massive ethmoidal adenocarcinoma with orbital invasion but minimal ophthalmic symptoms on presentation.
Methods: Case report of a 69-year-old, otherwise healthy, retired carpenter who was referred for treatment of bilateral senile cataract.
Results: A relative afferent pupillary defect and sectorial disc atrophy on ophthalmic examination led to further investigation and identification of an extensive ethmoidal neoplasm with orbital invasion.
