In December, the team of Professor Liu Longqian from the Department of Ophthalmology published a research paper entitled "Delayed correction for extrapolation in amblyopia" in Investigative Ophthalmology & Visual Science (IOVS), a top journal in the field of ophthalmology, revealing the abnormality of visual perception of movement in the amblyopic visual system.
The neural mechanism of amblyopia visual impairment provides new ideas

Amblyopia is an abnormal developmental disorder of the visual nervous system, and its visual system information processing is delayed

The results of the study found that the flash capture effect (FGE) value of amblyopic patients was significantly increased, and it was also found that even the contralateral eye with normal vision showed damage (Figure 2), revealing that the amblyopic visual system cannot accurately perceive motion visual information , There is an abnormality in visual perception of sports, and it is proposed that the mechanism of this visual impairment may be the delay of visual information processing in the amblyopic brain (Figure 3)
