Abnormalities of chromatic and luminance critical flicker frequency in multiple sclerosis.

abstract：PURPOSE:Retinal blood vessel diameter and arteriovenous ratio (AVR) are commonly used diagnostic parameters. Because vascular walls are typically not visible in funduscopy, clinical AVR estimation is based on the lumen rather than the entire vessel diameter. Here the authors used a transgenic mouse model to quantify AV...
