Abstract

By using a five-laser scanning laser ophthalmoscope with a choice of apertures in the retinal plane, we measured the reflectances of several retinal and choroidal features, relative to other features from the same image or to a model eye. Light scattering and absorption in the layers of the retina change the contrast of features as a function of wavelength. The mode of imaging also changes the appearance of these features, but this effect is not the same for all wavelengths. All wavelengths (488–830 nm) give a crisp image of the surface features of a normal retina with a 200 fim aperture confocal to the retinal plane. For other apertures, the appearance of features, such as the optic disk rim or the choroidal blood vessels, changes with wavelength.
