Spanish Translation. BRVO causes a sudden, painless loss of vision. In rare cases of an undetected vein occlusion, visual floaters from a vitreous hemorrhage blood vessels leaking into the vitreous gel of the eye can be the main symptom; this is caused by development of abnormal new blood vessels neovascularization in the retina.
Consider testing for clotting defects associated with arterial disease, including the antiphospholipid antibody syndrome and hyperhomocysteinemia. Even if a clotting abnormality is discovered, it may or may not be related to the ocular condition. Furthermore, treatment in the acute phase, especially with anticoagulation, may do more harm than good.
To investigate associated systemic diseases, other conditions, visual outcome, ocular complications and treatment in Swedish patients younger than 50 years with central retinal vein occlusion CRVO and reviewing the literature. Twenty-two patients with CRVO, younger than 50 years, were examined with full-field electroretinography ERG within 3 months after a thrombotic event, or were periodically examined and were observed for at least 6 months. In 18 of these patients, the initial retinal ischemia was studied using the cone b-wave implicit time in the 30 Hz flicker ERG.
This study aims to explore the prevalence, pattern and risk factors of retinal vein occlusion RVO in an elderly population of Nepal. Detailed history, visual acuity, anterior segment and posterior segment examinations were done. Blood pressure, non-fasting blood sugar, body mass index and abdominal girth were measured. Overall population prevalence for RVO was 2.

The primary outcome was the number of systemic abnormalities associated with these patients. Secondary outcomes included types of retinal vein occlusion and sites of occlusion. Atherosclerotic diseases were the most common systemic abnormalities associated with retinal vein occlusion and accounted for
Branch retinal vein occlusion is recognized by the following codes by the International Classification of Diseases ICD nomenclature:. ICD-9 Codes. ICD Codes.
Hyperhomocysteinemia is a well-known modifiable risk factor for thromboembolism. Retinal vascular occlusion in patients having hyperhomocysteinemia is a known entity, particularly in young patients. However, multiple extra macular branch retinal vein occlusion BRVO is a rare condition, which can be a presentation of this disease. We present a patient who had multiple extra macular BRVO; on complete systemic workup, he was found to have raised homocysteine levels.
