Postmortem Monocular Indirect Ophthalmoscopy

Abstract

Postmortem monocular indirect ophthalmoscopy permits examination of the posterior fundus and peripheral retina even if there is less than perfect anterior segment media such as postmortem corneal clouding. Light directed through the decedent's pupil from a bright focal light source illuminates the fundus and reflected light from the retina is then projected out of the eye. An aspheric condensing lens positioned in front of the eye focuses the retinal image at the focal plane of the lens. The real inverted, laterally reversed image comprises a wide field of view permitting evaluation of the decedent's fundus for retinal hemorrhages and other lesions.
