Summary
Antithrombin III (AT III) deficiency can cause severe blood clots. Researchers found AT III deficiency in two patients with retinal vessel occlusion, suggesting it may be a cause and warrants testing.
Area of Science:
- Ophthalmology
- Hematology
- Vascular Medicine
Background:
- Antithrombin III (AT III) is a crucial inhibitor of blood coagulation.
- AT III deficiency is a known risk factor for thrombosis and embolism.
Observation:
- Two otherwise healthy patients presented with retinal vessel occlusion.
- One patient experienced recurrent retinal vein thrombosis; the other had cilioretinal occlusion.
Findings:
- AT III deficiency was identified in both patients with retinal vessel occlusion.
- This suggests a potential causal link between AT III deficiency and retinal vascular events.
Implications:
- Determining AT III levels is recommended for patients with unexplained retinal vessel occlusion.
- Identifying AT III deficiency has significant therapeutic and prophylactic implications for preventing further thrombotic events.
