Description: A 27-year-old male patient, medically free, presented with unilateral left optic disc swelling. BCVA=1.0(OU), color vision, and contrast sensitivity were normal (OU) with no RAPD in the left eye. SS-OCT: showed left optic disc elevation with hyporeflective mass lesion (Fig-1 B). Enface OCT: showed left peripapillary hyperreflective ovoid mass lesions(Fig-2 D, Fig-3 F), FAF: showed left superonasal hyperautofluorescent drusenoid lesions. Orbital MRI with contrast was requested to exclude any optic nerve compressive lesions like (tumors: like mengioma or inflammatory lesions like granuloma (sarcoidosis). the result of orbital MRI was normal.
