title: A modified combined indirect ophthalmoscope and illuminated magnifying loupes.
abstract: A modified combined indirect ophthalmoscope and magnifying loupes with illumination was made by mounting a pair of Zeiss loupes below the SOLA indirect ophthalmoscope eye-piece. A beam-splitter, which was made of a piece of ordinary microscopic glass slide, splits a secondary light beam off from the original light source of the indirect ophthalmoscope at an angle of approximately 15 degrees to provide additional illumination for the magnifying loupes. The optics involved was discussed.
