Abstract
A visual field/visual acuity examination system includes a retinal projection head-mounted display; and a terminal device. The terminal device outputs examination image data to the retinal projection head-mounted display; displays an image on a display; and generates an examination image based on the examination image data and display the examination image on the display. The retinal projection head-mounted display inputs the examination image data from the terminal device; generates an image light beam based on the input examination image data and control emission of the image light beam from a light source; causes a scanning minor to scan the image light beam to generate an examination image light beam; and projects the examination image light beam as the examination image on a retina of an eyeball of a test subject after converging the examination image light beam in a vicinity of a pupil of the eyeball.
