Combined with leukemia is a risk factor for aggravating diabetic retinopathy. A combination of diabetic retinopathy and leukemia can be expected to have a rapid progression and patients often visit the department of ophthalmology first. In addition to the typical manifestations of diabetic retinopathy such as retinal venous tortuous dilation, microaneurysm, retinal hemorrhage and exudation, patients may also be associated with leukemic retinopathy. Areas of extensive capillary non-perfusion and neovascularization may appear in the early stage of mild microangiopathy. Moreover, severe complications such as vitreous hemorrhage, neovascular membranes and traction retinal detachment appear earlier, which may be a prognostic indicator for poor vision. The causes of leukemia aggravating diabetic retinopathy include retinal ischemia due to hyperviscosity, anemia and thrombocytopenia, direct infiltration of tumor cells, chemotherapy and radiotherapy, high level of vascular endothelial growth factor. In clinic, rapidly progressing diabetic retinopathy should alert the ophthalmologist to the underlying hematological disorder. Patients with both diabetes and leukemia need to be screened much earlier and followed up at shorter intervals. Early detection and aggressive management may help preserve visual acuity in such cases.
