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...

BACKGROUND/AIMS A moderately elevated plasma concentration of the sulphur amino acid homocysteine is an independent risk factor for atherosclerotic vascular disease. Many of the risk factors associated with coronary, cerebral, and peripheral atherosclerotic vascular disease are common to retinal vascular occlusive disease but it is unclear whether elevated plasma concentrations of homocysteine ...

Fifty-six patients with retinal vein occlusion--35 with central and 21 with branch vein occlusion--were investigated for comparison with an age and sex matched control group. Mean levels of beta-thromboglobulin and platelet factor 4 were significantly higher (p less than 0.001) in both the group with central and the group with branch retinal vein occlusion than in the control group. A significa...

Purpose: To document the development of central retinal vein occlusion secondary to orbital emphysema following nose blowing. Methods: A 55-year-old male developed central retinal vein occlusion secondary to orbital emphysema following nose blowing in the absence of trauma. Results: With conservative management his central retinal vein occlusion resolved over nine weeks period. Conclusion: The ...

The diagnosis and treatment of central retinal vein occlusion was reported in a young patient. Central retinal vein occlusion was probably related to secondary to reactive thrombocytosis after splenectomy. The patient was treated with steroids for papilledema and administered coumadin and aspirin. The symptoms resolved, and the findings returned to normal within three weeks. Current paper empha...

INTRODUCTION Central retinal vein occlusion is one of the major causes of severe vision impairment and blindness in adults. CASE PRESENTATION We present a case of unilateral ischemic central retinal vein occlusion in a 54-year-old woman with history of uncontrolled hypertension and open angle glaucoma. Laboratory tests including complete hypercoagulability and thrombotic workup were completed...

PURPOSE Impending central retinal vein occlusion is associated with mild or no loss of vision; however, its progress and vision prognosis have not been clearly defined until now. Therefore, we studied the progress and prognoses in patients with impending central retinal vein occlusion. METHODS For this study, we selected ten subjects who had been diagnosed with impending central retinal vein ...

BACKGROUND There are some cases that reported central retinal vein occlusion accompanied by ciliary artery occlusion, however, combined branch retinal artery and vein occlusion is a rare condition that has been infrequently reported. We describe in this report one case of retinal vein occlusion and branch retinal artery occlusion occurring simultaneously. CASE PRESENTATION A 50 year-old woman...
