This image depicted what is known as a fundoscopic view of the retina, or the back of the right eye. Note that the retinal vessels appeared to be emanating just right of center, from an area known as the optic disc. This is the point where the retinal arterioles and optic nerve entered the rear of the eyeball. The fundus displayed a pathologic phenomenon that had been caused by a condition known as polycythemia, or overabundance of red blood cells (RBCs). Note the tortuosity of the retinal vessels, their dark coloration, and accompanying luminal obstruction in the darkest vessels, due to the overabundance of RBCs.
