In vivo measurement of the lineal density of red blood cells in human retinal capillaries using high-speed adaptive optics ophthalmoscopy

We present an automated method for measuring the lineal density of red blood cells (RBCs) in human retinal capillaries using adaptive optics near-confocal ophthalmoscopy (AONCO). The spatiotemporal traces of RBCs flowing in retinal capillaries were extracted from AONCO images, enhanced using the Gab...
