Sequential occlusion of the branch retinal artery and branch retinal vein in a patient with hypertension: an interventional case report

Abstract

Norio Okamoto, Chota Matsumoto, Yoshikazu Shimomura Department of Ophthalmology, Kinki University Faculty of Medicine, Osakasayama City, Osaka, Japan 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 presented with acute visual loss in her right eye. Fundus photography showed retinal ischemia and tortuous, dilated retinal veins in the right eye. With early phase fluorescein angiography, retinal arteries revealed areas absent of branches. Late phase fluorescein angiography demonstrated that areas absent of branches were still present.Conclusion: It is a rare case of branch retinal artery and vein occlusion. Keywords: branch retinal artery occlusion, branch retinal vein occlusion, retinal vessel
