Abstract
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” × 6 for Neopan F and “50 W” × 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” × 2 for Fuji Color (ASA 100 Negative), “50W” × 3 for Fuji Color (ASA 100: Positive) and “50W” × 3 for Sakura Color. 3. For f luorescein angiography, 0.3ml/kg of 10 % sodium fluorescein was injected into the vein, and then photographs were taken under the condition of “100W” × 6. For monochrome photography (Kodak Tri-X ASA 400: Negative), a combination of Kodak Wratten Filter 47 (excitor) × 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 × K. W. 56, K. W. 47 A × K. W. 12. 15, K. W. 47 × K. W. 12.15 and Fuji Filter BPB 45 × BPB 55) were used and the films were developed by a double sensitivity method to obtain the best photograph.
