Eye: the door to undiagnosed chronic myeloid leukaemia.

Chronic myeloid leukaemia (CML) is a myeloproliferative neoplasm that can present in varied ways from incidental finding on haemogram to symptomatic presentation such as splenomegaly. We report an interesting case of a 22-year-old man who presented with loss of vision in right eye for 1 month. There were no pre-existing ocular or systemic diseases. On detailed ocular examination, a diagnosis of right eye rubeosis iridis, hyphaema, cataract and vitreous haemorrhage with left eye suspected leukaemic retinopathy was made. Routine haemogram revealed high leucocytosis. Systemic evaluation with investigations confirmed the diagnosis of CML and the patient was started on appropriate therapy.
