This paper describes a fundus reflection densitometer and its application to measurement of the foveal cone pigment regeneration of healthy subjects. A 500W xenon lamp provides bleaching, measuring and reference light beams. A PC9801 personal computer is used for control shutters of three beams, on-line calculation and display of cone pigment regeneration. When the bleaching light is on, the fundus can be viewed. The measuring field is fixed at 3.5deg. Using it, we have measured the two-way density and regeneration time of 5 healthy subjects (3 male and 2 female), with clear optical media and good visual acuity, ranging in age from 27 to 28 years. The two-way densities and regeneration times of 5 subjects show mean values of 0.426±0.038 SD and 152.5±21.1 SD s, respectively.
