[Photographic methods for observation of the eye-fundus of rhesus monkeys (author's transl)].

The method for observing the eye-fundus of rhesus monkeys was devised by the use of Kowa RC-2 Hand-held Fundus Camera. 1. For monochrome photography, Fuji Neopan F (ASA 32) and Fuji Neopan SS (ASA 100) films were used. The best result was obtained under the following conditions : the Strong Power Pack "50W" X 6 for Neopan F and "50W" X 3 for Neopan SS. 2. For color photography, Fuji Color (ASA 100 : Negative, Positive) and Sakura Color (ASA 100 : Negative) films were used. The best result were obtained under the following conditions : the Strong Power Pack "50W" X 2 for Fuji Color (ASA 100 : Negative), "50W" X 3 for Fuji Color (ASA 100 : Positive) and "50W" X 3 for Sakura Color. 3. Four fluorescein angiography, 0.3ml/kg of 10% sodium fluorescein was injected into the vein, and then photographs were taken under the condition of "100W" X 6. For monochrome photography (Kodak Tri-X ASA 400 : Negative), a combination of Kodak Wratten Filter 47 (excitor) X K. W. 15 (barrier) brought about the best photographic result. FOR COLOR PHOTOGRAPHY (Kodak Ektachrome High Speed ASA 160 : Positive), the filters (K. W. 32 X K. W. 56, K. W. 47 A X K. W. 12 . 15, K. W. 47 X K. W. 12 . 15 and Fuji Filter BPB 45 X BPB 55) were used and the films were developed by a double sensitivity method to obtain the best photograph.
