OBJECTIVE: To assess the change of cone motion perception in primary open-angle glaucoma (POAG). METHODS: The equi-luminance random dots moving test was used to determine the change of motion perception of blue, green, and red cones in 51 eyes with POAG. To isolate the three kinds of cones, the blue, green, and red visual targets were displayed on a yellow, purple, and blue-green back ground, respectively. RESULTS: The direction discrimination thresholds of motion perception from blue, green, and red cones were all damaged in POAG compared to that of the normal group, and among these, the blue cone was the most obviously changes. CONCLUSIONS: These findings indicate that cone motion perception, especially the blue cone, may reveal preclinical visual nerve damage in POAG. LA: Chinese
