Description: 27-year-old male, medically free, presented with left unilateral optic disc swelling. BCVA=1.0(OU), color vision, and contrast sensitivity were normal (OU)with no RAPD in the left eye. Swept Source OCT: showed elevated left optic disc with hyporeflective mass (Fig-1 B). Enface OCT: Showed left peripapillary multiple ovoid mass lesions(drusen) (Fig-2 d, Fig3 F). FAF: of the left eye showed superonasal hyper autofluorescent drusenoid lesions)(Fig3 E). Orbital MRI with contrast was requested to exclude any compressive lesions like tumors(menigioma)or inflammatory lesions like granuloma(sarcoid granuloma). orbital MRI result was normal.
