Chronic myeloid leukemia diagnosed from the course of diabetic retinopathy.

We report a case of chronic myeloid leukemia (CML), which was diagnosed during the management of proliferative retinopathy (PR) in a patient with type I diabetes mellitus due to the fulminant nature of the PR. This case highlights the importance of vigilance on the part of the ophthalmologist in the diagnosis of co-existing systemic disorders, notably hematological malignancy, which aggravates the posterior segment vasculopathy of the eye and the management of which is crucial for the patient. We also describe a short literature review on the clinical features, mechanism of the posterior segment vasculopathy of the eye, and management of PR co-existing in a patient with CML.
