The study intended to evaluate the combined examination of transient flash visual evoked potential (T-FVEP) and steady-state flash visual evoked potential (SS-FVEP) in diagnosis of optic neuropathy and macular disease. T-FVEP and SS-FVEP were examined in 22 cases (29 eyes) with optic neuropathy, 8 cases (9 eyes) with macular disease and 32 cases (32 eyes) of controls. The positive rates of T-FVEP and SS-FVEP in diagnosis of optic neuropathy were 83% and 100% respectively; that of combined examination was 100%. The positive rates of T-FVEP and SS-FVEP in diagnosis of macular disease were 5/9 and 7/9, and that of combined examination was 8/9. The positive rates of combined examination of T-FVEP and SS-FVEP in diagnosis of optic neuropathy and macular disease are higher than that of T-FVEP and SS-FVEP alone, and should be used routinely in the diagnosis of visual pathway disease.
