The post-capillary venule complex, small venules, large venules. Left eye point A represents the beginning of a ‘small venule’ segment, which ends at point B when two small venules converge. Point B is also the beginning of a large venule, which ends at the optic disc. The scale bar shows 1/3 disc diameter (~500 μm) from the convergence of capillaries on to the post-capillary venule, and approximates the length of the post-capillary venule complex. The post-capillary venule complex begins at the junction of two capillaries and extends a distance of 1/3 disc diameter downstream towards the small venules. Other visible features in this figure include disc leak, and intravascular filling defects (e.g. small venule at point A)
