This shows a portion of a horse's retina where there is loss of pigment and, therefore, choroidal vessels are easily seen. The bright yellowish tapetum is seen dorsally and the optic nerve can be seen on the right hand side of the slide. Due to the way the picture was taken the disc is somewhat obscured and there are also darker areas on this slide as well. However, the points of interest are the choroidal vessels and areas where you see only parts of choroidal vessels. You do not want to confuse these choroidal vessels with hemorrhage. Note again the vessels' similarity in width and also their linear arrangement.
