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 AVR in vivo based on total vessel dimensions (wall and lumen). METHODS: Confocal scanning laser ophthalmoscopy (cSLO) and indocyanine green angiography of the retinal vasculatur...Expand abstract
