[A new indirect binocular spectacle ophthalmoscope]

A new indirect spectacle ophthalmoscope is described. Its main features are a fixed interpupillary distance (59, 62, 65, 68 mm.), a variable viewing beam stereoangle, a precentered halogen lighting beam with Maxwellian view and an iris diaphragm to limit the viewing area, which has never been a feature of a binocular ophthalmoscope before. These features, on a lightweight spectacle frame, make indirect binocular ophthalmoscopy an easy-to-master method even for examining patients with small pupils and hazy media.
