cardiovascular system
abnormal retina vasculature morphology ( J:212472 )
• P5 retinas show a 18.0% reduction in the area covered by the vascular plexus relative to wild-type retinas
abnormal retina blood vessel morphology ( J:212472 )
• P5 retinas show a 16.9% reduction in total vessel length relative to wild-type retinas
• however, vessel length density (ratio of total vessel length to vascular area) and fractal dimension (a measure of tortuosity) remain normal
