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 ˜15° to provide additional illumination for the magnifying loupes. The optics involved was discussed.
