Visual acuity was completely lost, and pupil's direct response to light was absent; It is called Gunn's phenomenon that the vision is seriously impaired, the pupil's direct response to light is weakened, the pupil of the diseased eye is continuously illuminated, it begins to shrink, and then automatically expands, or in the natural light, it covers the healthy eye, the pupil of the diseased eye is enlarged, the pupil of the healthy eye is covered, and the pupil of the healthy eye remains unchanged.
