Vogt–Koyanagi–Harada disease in a patient of chronic myeloid leukemia

This case report describes the concurrent development of Vogt–Koyanagi–Harada (VKH) disease in a 39 year old male patient of chronic myeloid leukemia (CML). The patient being reported was a known case of CML in remission with history of painless sudden loss of vision in both eyes. Cases of leukemia can present with visual loss due to multiple ocular manifestations of leukemia itself or side effects of modern drugs used for its treatment. Clinical examination and multimodal imaging of our patient were suggestive of concurrent development of VKH. The patient was started on oral steroids, to which he showed a good response. Thus, the cases of CML may rarely develop concurrent ocular disorders not related to leukemia. These associated ocular disorders need to be distinguished from the ocular manifestations of leukemia itself. Our case highlights the concurrent development of VKH as the etiology of visual loss in a case of CML.
