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,...

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...

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...

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 ...

Ophthalmic involvement in giant cell arteritis can manifest in a number of ways. Central retinal artery occlusion is one of the common causes of visual loss in giant cell arteritis. On the contrary, branch retinal vein occlusion is rarely associated with the latter. We report an 89-year-old lady with acute left central retinal artery occlusion on a background of progressive decline in vision ov...

purpose: to determine the effect of intravitreal triamcinolone (ivt) injection on visual acuity in patients with ischemic central retinal occlusion (crvo). methods: this randomized clinical trial was performed on patients with ischemic crvo referred to the retina clinic at feiz hospital in 2007-2008. inclusion criteria were: duration of crvo less than one month, normal iop, no sign of diabetic ...

Asymptomatic chronic retinal vein occlusion that occurs in chronic simple glaucoma is described. The condition is characterized by marked elevation of retinal vein pressure with collateral vessels and vein loops at the optic disc in cases of central vein occlusion, or retinal veno-venous anastomoses along a horizontal line temporal and nasal to the disc in hemisphere vein occlusion. No patient ...
