Activated protein C resistance in central retinal vein occlusion

Diagnosis of activated protein C resistance in retinal vein occlusion.

EDITOR,—I read with interest the article published in the BJO by Hunt. 1 In this paper the author reports that the prevalence of APC resistance is more common than any other known thrombophilic state and was present in over one third of patients younger than 45 years with central retinal vein occlusion (CRVO). Therefore, many would argue that a full thrombophilia screening should be performed i...

Activated protein C and retinal vein occlusion.

Activated protein C resistance, factor V Leiden, and central retinal vein occlusion in young adults.

OBJECTIVE To confirm the relationship between resistance to activated protein C (APC), factor V Leiden, and central retinal vein occlusion in young adults as reported in a recent study of patients younger than 50 years. PATIENTS AND METHODS Patients younger than 50 years with central retinal vein occlusion were identified from the medical records of the Wills Eye Hospital Retina and Retina Va...

Activated protein C resistance in patients with central retinal vein occlusion.

AIM/BACKGROUND A new defect in the anticoagulant system has recently been discovered--activated protein C resistance. The frequency of this disorder has been shown to be increased in young patients (< 50 years of age) with central retinal vein occlusion. This study was carried out to determine if there was any overrepresentation of activated protein C resistance in patients > 50 years of age wi...

Sulfur Mustard Exposure and Non-Ischemic Central Retinal Vein Occlusion

A 41-year-old man was referred with a complaint of visual loss in his left eye and his best corrected visual acuity was 20/80. Slit lamp examination showed arborizing conjunctival vessels and dry eye. Fundus examination and fluorescein angiography revealed a non-ischemic central retinal vein occlusion. Cardiovascular, rheumatologic, and hematologic work up showed no abnormal findings. An ascert...
