Polarized light photographs have been taken of a monkey retina at discrete wavelengths from 400 to 830 nm. These photographs show a cross-like figure overlying the macular area. Because of the position and shape of this cross it is probably due to the same structure in the eye that produces the Haidinger's brushes phenomenon. This polarization figure is attributed to effects arising from the dichroism of Henle's layer. © 1978.
