Hypotension is the most frequent complication of haemodialysis. We report a case of acute visual impairment after one session of haemodialysis in a context of an acute optic neuropathy. The immunological and serological studies were negative. The records of hypotension greater than usual after the dialysis session that coincided with the visual complaints strongly suggest the dialysis-induced hypotension is the underlying mechanism of this non-arteritic anterior ischemic optic neuropathy.
