Abstrakt:	To describe a case of cocaine-induced midline destructive lesions (CIMDL) associated with ocular autoimmune disease.Methods: Observational case report. A 45-year-old man with history of chronic osteolytic sinusitis due to cocaine abuse presented with sudden vision loss in right eye. Ophthalmic examination revealed fixed right mydriasis with extraocular movements limitation and optic disc swelling. Computed tomography showed an orbital infiltrating mass. The diagnosis of orbital-apex syndrome secondary to CIMDL was established. Steroids and antibiotics therapy were started without vision improvement. At 6-months follow-up, a corneal ulcer with characteristics of peripheral ulcerative keratitis (PUK) was evidenced, coinciding with an upper respiratory bacterial infection. CIMDL and PUK share common pathogenic pathways, with implication of autoimmune factors and exposure to infective antigens. We hypothesized that chronic cocaine use, along with persistent bacterial infection, could have triggered an inflammatory reaction, which contributed to CIMDL development and the appearance of PUK.
