Computerised perimetry with moving and steady fixation in children.

The computer assisted moving eye campimeter (CAMEC) maintains the patient's interest and fixation by using a moving fixation target which must be tracked by the patient using a joystick for the test to proceed. In this study, 32 children were examined with the blind spot test programs of both CAMEC and the Dicon Auto-Perimeter. Among those who completed both tests the blind spot was detected in 18 eyes (75%) by the Dicon Auto-Perimeter and in 24 eyes (100%) by CAMEC. The mean CAMEC score (61.0%) was significantly higher than the mean Dicon Auto-Perimeter score (26.6%). CAMEC allowed better detection and quantification of scotomas in patients more than 4 years of age.
