AIM: To explore the visual evoked potential in infantile orbital cellulitis' clinical applications by monitoring the visual evoked potential changes in infantile orbital cellulitis before, during and after treatment.

METHODS: Twenty-three cases of CT diagnosed single orbital cellulitis were examined by the visual evoked potentials. The affected eyes as observation group, and healthy eyes as control group. Comparative observation of visual evoked potential changes in amplitude and incubation period before, during and after the treatment.

RESULTS: Compared with the control group, the observation group's visual evoked potential changes included reduced amplitude, extended incubation period. With the treatment progress, the observation group had gradual increase in amplitude, gradual reduction in incubation period.

CONCLUSION: In infantile orbital cellulitis, the use of visual evoked potentials is a simple, feasible and effective method to monitoring the visual function during the treatment.
