PROBLEM TO BE SOLVED: To provide an ophthalmologic examination apparatus capable of examining both of a subjective visual field examination and an ERG (Electric Retinogram) examination by a single examination device, having an excellent contrast ratio, and providing a sufficient amount of irradiation light.SOLUTION: Besides red, green, and blue (RGB) light sources, the ophthalmologic examination apparatus includes a while light source, employs the RGB light sources for a subjective visual field examination and the white light for an objective visual field examination, and further reflects the respective color light beams emitted from the respective light sources by using a DLP (Digital Light Processing) projector 70 to apply stimulus light to a prescribed position on the fundus oculi retina. This configuration can apply the stimulus light to the fundus oculi retina by reflection without reducing an amount of light emitted from the light sources and apply the stimulus light with excellent contrast ratio.SELECTED DRAWING: Figure 1 |
