瞬态和稳态闪光视诱发电位联合检测的临床价值

探索瞬态闪光视诱发电位（FVEP）和稳态FVEP联合检测对视神经病变和黄斑病变的诊断价值。对22例（29眼）视神经病变、8例（9眼）黄斑病变患者和32例（32眼）正常人进行瞬态FVEP和稳态FVEP检测。视神经病变组上述2项检测的阳性率分别是83％和100％，联合检测的阳性率为100％；黄斑病变组阳性率依次为5／9和7／9，联合检测为8／9。联合检测较单一检测阳性率高，应常规联合检测，提高对视路疾病的诊断价值。

Clinical value of combined examination of transient and steady-state flash visual evoked potential

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.
