Although von Willebrand disease is the most common inherited bleeding disorder, there are only a few published reports of ocular complications. To our knowledge, this is the first case of peripheral retinal ischemia and retinal neovascularization in a patient with von Willebrand disease.
PURPOSE
This study aimed to demonstrate the value of multispecialty care when exploring a diagnosis for bilateral retinopathy.
CASE REPORT
A 55-year-old African American woman presented with peripheral retinal hemorrhages on routine examination. She was asymptomatic and did not have any personal or family history of bleeding disorders. Blood work was ordered, and she was referred to a retinal specialist who found peripheral telangiectasia, retinal ischemia, and leakage on fluorescein angiography, consistent with retinal neovascularization. Laser photocoagulation was performed while numerous specialists were consulted to determine the cause for her retinopathy. Laboratory testing confirmed low-grade type 1 von Willebrand disease. She was monitored without systemic treatment. She remained stable and asymptomatic, but her retinal neovascularization did not regress fully, so laser treatment was repeated.
CONCLUSIONS
This case described a new finding of peripheral retinal ischemia and retinal neovascularization in von Willebrand disease. It was discovered in an asymptomatic patient who did not have a history of bleeding but presented with bilateral retinal hemorrhages. Diagnosis was challenging because of the high degree of variation in this bleeding disorder, requiring extensive testing and careful consideration of the individual's clinical profile. Most people with von Willebrand disease do not know they have the disease because symptoms are mild or absent, so most cases are unreported. The von Willebrand factor is poorly recognized in ocular disease, but given its role in angiogenesis, it may be a valuable target to consider in future research.Permalink : https://bibliotheque.helb-prigogine.be/opac_css/index.php?lvl=notice_display&id= [article]Exemplaires
