Using the Full Resources of the Direct Ophthalmoscope

Modern direct ophthalmoscopes offer a broad selection of filters, apertures and focal powers. Their use, with the increase in available illumination, permits the informed examine to make a more definitive examination of the ocular fundus and intervening media. When a first examination of a patient is made and recorded in detail, it affords a base line from which early pathological or other change has increased probability of being detected. A form for organization of such an examination using the instrument's full resources concludes the discussion.
