[Ischemic occlusion of the central retinal vein and protein C deficiency]

|January 1, 1990
Insights
Reduced protein C activity was observed in a patient with central retinal vein thrombosis and neovascular glaucoma. This suggests protein C may contribute to ocular vaso-occlusive diseases.
Area of Science:
- Ophthalmology
- Hematology
- Vascular Biology
Background:
- Central retinal vein thrombosis (CRVT) and neovascular glaucoma are severe ocular conditions.
- Understanding the underlying causes of vaso-occlusive events in the eye is crucial for effective management.
Observation:
- A 52-year-old female patient presented with ischemic central retinal vein thrombosis and neovascular glaucoma in her left eye.
- Laboratory tests revealed significantly reduced protein C activity (32%).
Findings:
- Protein C, a key inhibitor of hemostasis, was found to be deficient in this patient.
- This finding supports the potential role of protein C deficiency in the pathogenesis of ocular vaso-occlusive diseases.
Implications:
- Measuring protein C levels may be beneficial for patients with a history of thromboembolic events or suspected coagulation disorders.
- Further research into the link between protein C and ocular vascular diseases is warranted.
Abstract:
We present a case of a 52-year-old woman suffering from an ischemic central retinal vein thrombosis with neovascular glaucoma of her left eye. Protein C activity was found to be reduced (32%). This supports the hypothesis that protein C may play a role in the pathogenesis of ocular vaso-occlusive disease, as protein C is an important inhibitor of hemostasis. Thus, we suggest to measure protein C in patients with preceding thromboembolic diseases or assumed disorders of coagulation.
