Figure 1: (a) Microscope illumination versus (b) Intracameral illumination. A red reflex is produced by reflection of bright coaxial light from the macula back to the observer (the ocular of an operating microscope) (a). Illumination, while, a side light of intracameral illumination is shining into not macula but peripheral retina. Therefore, the light reflection from the macula back to the observer is decreased (b)
