Case report: retinopathy in a patient with cold hemagglutinin disease.
OBJECTIVE
We describe abnormalities of retinal vasculature and blood flow in a patient with cold hemagglutinin disease.


METHODS
Case report and literature review using the PubMed database.


RESULTS
A man with cold hemagglutinin disease and no visual symptoms was referred to the Eye Department with retinal abnormalities found during a routine optometrist examination. He was found to have scattered retinal hemorrhages, abnormal retinal vasculature resembling neovascularization (but that did not show leakage on fundus fluorescein angiography), and aggregated material flowing visibly in the retinal vessels.


CONCLUSIONS
No specific descriptions of retinopathy related to cold hemagglutinin disease have been previously published. We suggest that the abnormalities are secondary to areas of retinal ischemia, resulting in the development of a form of collateral circulation.
