<P>PROBLEM TO BE SOLVED: To provide a retinal function measuring apparatus capable of stably measuring the retinal function of an eye to be examined. <P>SOLUTION: The retinal function measuring apparatus comprises an objective optical system arranged in front of the eye to be examined E, an observation light optical system 10 for illuminating the retinal region of the eye to be examined via the objective optical system, a light receiving optical system 20 for acquiring, a retinal image by receiving reflected light from the retinal region illuminated by the observation light optical system 10 via the objective optical system, and a retina stimulating optical system 30 for stimulating the retina by irradiating the retinal region of the eye to be examined with visible stimulating light. The retinal function measuring apparatus acquires information about change of the retinal function through operation processing of the retinal images before and after irradiation with the visible stimulating light by the retinal stimulating optical system 30. The objective optical system has an objective concave mirror 1 which illuminates the predetermined region of the retina of the eye to be examined with reflecting illumination light from the observation light optical system 10 and by converging the light in the vicinity of the pupil of the eye to be examined. <P>COPYRIGHT: (C)2007,JPO&INPIT |
