Ocular problems in patients who have acute myeloid leukaemia (AML) are commonly observed. Orbital and ocular lesions carry a poor prognosis in patients with acute myeloid leukemia. Direct invasion of the retina and choroid with the neoplastic cells is common, but the involvement of the optic nerve, uveal tract are relatively rare. Ocular symptoms include blurred vision and diplopia due to the involvement of optic nerves. This paper reports a 68 year old patient with AML. 5 azasitidin was initiated for treatment. By the second cycle, he complained of vision loss for right eye. These findings occured for left eye after three days. Optic nerve involvement was found with orbital magnetic resonance imaging with contrast. We report these patient because of rarity. http://pubs.sciepub.com/ajmcr/3/4/7/ajmcr-3-4-7.pdf acute myeloid leukemia diplopia optic nerve infiltration vision loss
