Cortical spreading depolarization is a metabolically costly phenomenon that affects the brain in both health and disease. Following severe stroke, subarachnoid hemorrhage, or traumatic brain injury, cortical spreading depolarization exacerbates tissue damage and enlarges infarct volumes. It is not known, however, whether spreading depolarization also occurs in the retina in vivo. We report now ...

Retinal vein occlusion (RVO) and diabetic retinal disease is the most widespread type of retinal disorders. The precisely extracted Retinal blood vessel provides a vital factor in the early diagnosis of retinopathy. In this paper a programmed method is proposed to enhance the performance evaluation of feature extraction technique to obtain the affected ocular fundus images in the retinal blood ...

   Introduction: Retinal vein occlusion  is a common vascular disorder disrupting vision. Two basic types of RVO are branch retinal vein occlusion and central retinal vein occlusion (CRVO).  Retinal vein occlusion is a multifactor process including systemic illness and local retinal factors.RVO may be associated with atherosclerotic risk factors. We analyzed the role of 2 dimensional transthor...

retinal vein occlusion (rvo) is a common retinal vascular occlusive disorder and is associated with a variety of systemic risk factors. the aim of this study was to investigate whether the underlying diseases were evaluated and managed appropriately by ophthalmologists. we performed a study of 1344 patients with retinal vein occlusion (rvo). patients were evaluated with a questionnaire includin...

Neovascularization after retinal branch vein occlusion (RBVO) has long been recognized (Foster Moore, 1924; Jensen, 1936) and it has been noted more recently in a number of publications. Krill, Archer, and Newell (I97I) found that three out of 14 patients had new vessel formation after RBVO; Michels and Gass (1974) found seven cases of retinal new vessels in 28 eyes and disc new vessels in two ...

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 ...
