(same eye as in Figure 2 ). View through the slit lamp microscope if a 3.5 mm circular aperture is projected onto the central fundus through lenses with the power +90, +60, +40, +55D (see Figure 4). The higher the power of the examination lens, the less the magnification of the image visible in the slit lamp biomicroscope (also compare to Figure 2, bottom right, for the size of the illuminated fundus area).
