Abstract: In condition of direct vision on fundus of eye, microperimeter can quantitatively detect the retinal light sensitivity of macular area, and record real time tracking of the eye, automatically analyze the location and stability of fixation. Microperimeter matches fundus image with micro cyclogram point-to-point, thus it achieves the combination of visual function and structure. The characteristics of microperimeter have good relations with subjective vision, so it can be a new method for the accurate vision evaluation and has application potential to assess the visual function in legal medicine. In this article, we summarize the principle, method and parameters of microperimeter. Also, the applications of microperimeter in vision assessment are focused in order to provide a reference for the assessment of visual function in the legal medicine.
