PURPOSE To investigate the medical backgrounds of patients and the treatment periods from the onset of branch retinal artery occlusion to obtaining improved final visual acuity. METHODS This was a retrospective case series study. A total of 68 consecutive patients (69 eyes) with branch retinal artery occlusion who visited Tokyo Medical University Hospital from 2007 to 2012 were included in th...
Q. What conditions comprise ocular thrombosis? CJG Ocular thrombosis includes central and branch retinal vein occlusion (CRVO), central retinal artery occlusion (CRAO), amaurosis fugax (AF), and non-arteritic ischemic optic neuropathy (NAION), all of which are closely related to coagulation abnormalities. In the United States, branch and central retinal rein occlusions are the second most comm...
Human retina consists of repeating pattern of arteries and veins. This repeating pattern is known as Fractals. Fractal Dimension is the quantity which is to be determined for analyzing disorder in retina using fractal analysis. There are two disorders of retina which leads to complete vision loss. They are Occlusion and Diabetic Retinopathy. Occlusion is due to arteries crossing over vein leadi...

Retinal artery embolization after carotid artery stenting: report of a case and review of literature
Background: Retinal artery occlusion is an uncommon but serious complication during carotid artery stenting (CAS) for carotid artery stenosis, which induces the visual defect in patients. Case presentation: A 74-yearold man was admitted to our hospital because of intermittent dizziness and limb weakness in the past one month. Cerebral angiography revealed 86% stenosis on the start of the right ...
Iatrogenic retinal vein to choroidal vein anastomoses were created using laser photocoagulation in six of seven dog eyes in which a partial branch retinal vein occlusion had previously been created photochemically. A similar attempt to create an anastomosis was made in six control eyes in which no branch vein occlusion was present. In the eyes in which a branch retinal vein had been created, a ...
