| Abstract: | 2 normal subjects were taken pictures for their optic nerve head by using the monochromatic photography system we devel-oped. A densitometer was used in selecting the optimal fiIters. A comparison was made in contrast and image quality of opitc nervehead between negative films of monochromatic light and red-free light, and picture of monochromatic light and colour postive pic-ture of white light by using the method of psyco-physics. The results showed that optic disc and optic cup have an optimal contrastand best resolution under illumination of 628nm and 530nm. The optic nerve head image under monochromatic light is better thanthat under red free-light and white light. |
