[Computer evaluation of infrared photos of the optic fundus. II. Clinical aspects (author's transl)]. Computergesteuerte Auswertung von Infrarotbildern des Augenhintergrundes. II. Klinische Aspekte. The absorption of retina and uvea pigment is very high in infrared light of 700-1000 nm, whereas hemoglobin absorbs light of lower frequencies much better. Density-Slicing is performed by a computer receiving information from an infrared film. Pigments of nevi and melanomas are demonstratable by this method and tumor growth is possible to see as well.
