Thirteen patients with optic neuritis who recovered normal visual acuity and kinetic perimetry all showed impairment of foveal critical flicker frequency, a psychophysical test of visual temporal resolution. Because the magnocellular visual system demonstrates higher temporal resolution than the parvocellular system, this finding implicates involvement of axonal projections of magnocellular retinal ganglion cells in recovered optic neuritis.
13名视盘炎患者视力恢复正常且动态视野检查正常，但均表现出中心凹临界闪烁频率受损，这是一种视觉时间分辨率的心理物理学测试。由于大细胞视觉系统比小细胞系统表现出更高的时间分辨率，这一发现提示在视盘炎恢复过程中，大细胞视网膜神经节细胞的轴突投射受到了影响。
