To investigate how a child patient in an inverted dorsal position looks at the face of his dentist in a sitting position in the treatment room, the child's eye movements were determined, using a photograph of the dentist's face as a test image. The based an results of eye movements were analyzed based on gazing time, gazing frequency, time up to primary seeing, glance-scanned scope, angle of saccadic eye movements, contour line-passed frequency, glance directivity, primary gazing site and figure-background relationships. Then, the subjects were divided into a group of 74 children aged below 6 years and a group of 100 children aged above 6 years and a comparative examination of the results of eye movements between both groups led to the following conclusions:
1. Age differences in eye movements were noted in glance-scanned scope, angle of saccadic eye movements and contour line-passed frequency.
2. The children aged below and above 6 years proved to have glance scanning confined to narrow and broad scopes, respectively.
3. The children aged below and above 6 years proved to show small and large angles of saccadic eye movements respectively.
4. The children aged below and above 6 years had concentrated their vision inside the dentist's face and shifted between the face and the background beyond the contour, respectively.
5. Compared with the children aged above 6 years, the children aged below 6 years tended to recognize the entire characteristics of dentist's face.
