BACKGROUND To determine the correlation between the optic nerve head (ONH) circulation determined by laser speckle flowgraphy and the best-corrected visual acuity or retinal sensitivity before and after intravitreal bevacizumab or ranibizumab for central retinal vein occlusion. METHODS Thirty-one eyes of 31 patients were treated with intravitreal bevacizumab or ranibizumab for macular edema d...

The proposed study will measure and characterize early retinal vessel changes in persons with diabetes and persons at high risk of diabetes (impaired fasting glucose [IFG], impaired glucose tolerance [IGT], and the metabolic syndrome) in the Australian Diabetes, Obesity and Lifestyle Study (AusDiab), a population-based study of risk factors and complications of diabetes. Specifi c Aims of the s...

in this paper, a novel matched filter based on a new kernel function with cauchy distribution is introduced to improve the accuracy ofthe automatic retinal vessel detection compared with other available matched filter‑based methods, most notably, the methods builton gaussian distribution function. several experiments are conducted to pick the best values of the parameters for the new designedfi...

purpose : central retinal vein occlusion (crvo) is the most common vascular event in the eye after diabetic retinopathy. this study was conducted to evaluate the effect of intravitreal triamcinolone (ivt) on acute crvo. materials & methods : in a randomized sham-controlled clinical trial, 27 eyes with recent onset (less than 2 months) crvo were randomly assigned to two groups. the treatment gro...

BACKGROUND We report a case of bilateral central retinal artery occlusion and the evaluation of retinal vasculature and capillaries by using optical coherence tomography angiography. CASE PRESENTATION A 75-year-old white man presented with central retinal artery occlusion in one eye and underwent a carotid angioplasty. Upon discontinuing anticoagulant, he had a subsequent central retinal arte...
