This article describes how transillumination is used to enhance photographs of retinal hemorrhages.
Abstract
Light stand photography with direct illumination of the retina is a common method of demonstrating retinal hemorrhages. The lack of contrast between dark hemorrhages and surrounding dark retina, and the difficulty of photographing into the concavity of an eye, limit this technique. Transillumination of a bivalved globe with a bright external light source such as a colonoscope or microscope light yields high-contrast superior photographs. This technique is useful to document retinal hemorrhages, and provides quality photographs for courtroom demonstrations. Figures, references
