Central retinal vein prethrombosis as an initial manifestation of protein S deficiency
Keywords:
Retinal vein, Protein S deficiency, Vascular diseases, Case reportsAbstract
CONTEXT: Retinal vein thrombosis is most common in old people, and is often associated with systemic vascular disease. One of its rare systemic causes is protein S deficiency. CASE REPORT: A case of a 21-year-old woman with retinal vein prethrombosis associated only with protein S deficiency is described. She presented with acutely reduced visual acuity and a central scotoma in her left eye. Warfarin therapy was initiated, and complete improvement in ophthalmoscopic findings was subsequently observed. This case illustrates that protein S deficiency is a factor that should be considered in cases of retinal vein occlusion, particularly in young patients.
