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 ...
Abbreviations: AD, maximum amplitude in the dark period; AL, minimum amplitude in the light period during FO measurement; BRVO, branch retinal vein occlusion; CRAO, central retinal arterial occlusion; CRVO, central retinal vein occlusion; dfFO, average difference in μV between AD and AL during the FO measurement; df/mFO, percentage ratio of the dfFO to the average amplitude of AD + AL (m); EOG,...
We aim to describe a case of central retinal vein occlusion associated with this is a case report of a 45-year-old patient who was admitted for management of thrombotic thrombocytopenic purpura (TTP). He developed left central retinal vein occlusion three months later. The retinal vein occlusion resolved gradually as his TTP started to respond to medical treatment but significant macular edema ...
Doppler ultrasound was used to detect possible flow changes in the carotid arteries of patients with central retinal artery and vein occlusion. Twenty-three patients with central retinal artery occlusion (mean age 56, SD 11, years) were examined 4 to 48 months after the development of the occlusion and compared with age and sex matched control subjects with no history of any disease known to be...
introduction : branchretinal vein occlusion (brvo), in which one of the branches of the main vein are blocked, andcentral retinal vein occlusion (crvo) in which the main vein of the eye is blocked often occur in elderly people and are the second to diabetes in producing disease of the vessels of the retina. the main causes of vein occlusions in middle and young aged population is not well...
Whole-blood and plasma viscosity with haematological and biochemical investigations were measured in 44 patients with retinal vein occlusion. The patients were subdivided on the basis of fluorescein angiographic findings into: 1. Those with large areas of capillary non-perfusion. 2. Those with small areas of capillary non-perfusion. 3. Those with an intact capillary pattern. Capillary non-perfu...
Ninety-nine patients with retinal vein occlusion (40 with central, 59 with branch vein occlusion) were investigated for the prevalence of associated diseases for comparison with an age-matched control group. There was a significantly increased prevalence of hyperlipidaemia (p less than 0.001) and hypercholesterolaemia (p less than 0.001) in the group with branch retinal vein occlusion and of hy...
Retinal vein occlusions may decrease visual acuity. There is no known therapy to treat ocular thrombosis. The authors used fondaparinux, an ultra-low-molecular-weight heparin, to treat 13 consecutive cases of recent-onset retinal vein occlusions. Two patients with renal insufficiency were not included. Eight central retinal vein occlusions and 5 branch retinal vein occlusions in 13 patients wer...
