[Value of standardization of clinic visual electrophysiology in objective visual function evaluation].

Visual electrophysiological examination, which features the advantage of being objective, noninvasive and quantitative, is an important method for visual function assessment. The problem yet to be resolved in clinical and medical authentication, is the standardization of application, particularly in terms of test procedure and results interpretation. Visual electrophysiology examination includes many tests. Each kind of test has its own clinical significance. There are many factors that may affect results. Therefore, the standardization in the examination procedure can ensure the accuracy and repeatability of the result. The interpretation of the report, which relies upon both clinical operation guidance and clinical experiences, also needs to be standardized. Focus should be put on the issues above in an effort to realize the reasonable application of visual electrophysiology in clinic diagnosis and medical authentication, and to avoid the misjudgment or misdiagnosis. .
