Oxygen saturation in branch retinal vein occlusion

Dorzolamide 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...

Branch retinal vein occlusion.

Retinal vein occlusions (RVO) are the second commonest sight threatening vascular disorder. Branch retinal vein occlusion (BRVO) and central retinal vein occlusion (CRVO) are the two basic types of vein occlusion. Branch retinal vein occlusion is three times more common than central retinal vein occlusion and- second only to diabetic retinopathy as the most common retinal vascular cause of visu...

Branch 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...

Evaluation of Optical Coherence Tomography Angiography Findings in Patients with Branch Retinal Vein Occlusion

Purpose: To analyze the correlation of optical coherence tomography angiography (OCTA) findings with visual acuity (VA) in patients with branch retinal vein occlusion (BRVO). Methods: This cross-sectional study was performed on 20 eyes of 20 patients with unilateral BRVO involving the macula referred to the ophthalmology clinic of Rassoul Akram Hospital. OCTA imaging was conducted for all patie...
