The photopic negative response (PhNR) has recently been shown to be severely affected in central retinal artery occlusion (CRAO), despite relative preservation of the cone b-wave compared to that in the healthy unaffected fellow eye. The aim of this study was to test how the PhNR of the flash electroretinogram (ERG) is affected in human retinal vein(More)
PURPOSE To test how the PhNR of the flash ERG is affected in human nonproliferative diabetic retinopathy (NPDR). METHODS The PhNR was elicited with red stimuli (5 cd s/m(2) with 4-min duration) and blue background (10 cd/m(2)). Standard Ganzfeld flash ERGs were recorded according to the ISCEV standard for the clinical electroretinogram (2004). A total of(More)
To investigate the retinal development in healthy preterm infants through standard ganzfeld electroretinograms (ERG) and compare the difference of ERG between the healthy preterm and term infants. Forty-nine 49 healthy infants were recruited to this study, including 20 preterm and 29 term infants. All the infants were grouped as follows: term 40 W group(More)
PURPOSE To study the characteristics of photopic flash electroretinogram (ERG) in normal adult SD rats. METHODS Sixty normal adult SD rats aged 9 to 12 weeks were enrolled in this study. Photopic flash ERG were recorded from these 60 SD rats. The results were statistically analyzed with SPSS software. RESULTS Stable a, b and PhNR wave could be recorded(More)
The paper researches on the inflation level forecasting for China and the United States in one kind of univariate and three kinds of bivariate cases, using Vector Autoregressive and Bayesian Vector Autoregressive Models, based on the rolling-sample forecasts and the mean absolute percentage error standard. Empirical tests show that, both China and the(More)
PURPOSE To investigate and compare the latency and amplitude of the electroretinogram (ERG) photopic negative response (PhNR) between young and old Lewis rats. METHODS Thirteen Lewis rats were divided into two groups according to ages, young group (3-month old n=5) and old group (24 month old n=8). The ERGs of the left eyes were measured and the latency(More)
PURPOSE The purpose was to report a case of unilateral retinitis pigmentosa with amblyopia in the other eye. METHODS Eight years ago, a 36-year-old woman complained of peripheral visual field loss in her left eye when she covered her right eye. Complete ophthalmological examinations including fundus photography and fluorescein angiography, full-field(More)
