Cilio-retinal arterial circulation in central retinal vein occlusion.
The hypothesis that an occlusion of the central retinal artery is an essential prerequisite for haemorrhage formation after central retinal vein obstruction has been investigated by examining the fundus changes in patients with a cilio-retinal arterial circulation; the findings are at variance with the 'combined occlusion hypothesis'. Comparisons were made between the pathological features in t...
متن کاملRetinal Pathology after Central Retinal Vein Occlusion.
OCCLUSION of the central retinal vein causes incomplete haemorrhagic infarction of the inner layers of the retina. Haemorrhagic infarction describes a situation in which the venous backflow of an area of tissue is interrupted. As a result the flow of blood has to stop; ischaemia and resulting increase of vascular permeability lead to retinal oedema and extensive haemorrhages. The central retina...
متن کاملSulfur 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...
متن کاملBranch Retinal Vein Occlusion followed by Central Retinal Vein Occlusion
A 59-year-old woman with history of noninsulin dependent diabetes mellitus and systemic hypertension presented with decreased vision in her left eye since 2 months ago. Bestcorrected visual acuity (BCVA) was 20/20 and 20/400 in the right and left eyes respectively. Relative afferent pupillary defect was negative. Anterior segment examination was unremarkable except for mild posterior subcapsula...
متن کاملDorzolamide increases retinal oxygen tension after branch retinal vein occlusion.
PURPOSE To study the effect of dorzolamide on the preretinal oxygen tension (RPO(2)) in retinal areas affected by experimental branch retinal vein occlusion (BRVO) in pigs. METHODS Experimental BRVO was induced by diathermy close to the optic disc. RPO(2) was measured with an oxygen-sensitive electrode 0.5 mm above the BRVO-affected area, which was compared to the retinal areas not affected b...
