Vessel changes in the optic fundi of patients with cerebral malaria. Vessels that are normally red in color become orange or yellow because they contain parasitized red cells. The parasite consumes some of the hemoglobin in solution, so those red cells become less red. In the image on the left, all three features of malarial retinopathy are present (white-centered hemorrhages, vessel changes, and whitening in areas of the retina).
