Diagnostic performance of isolated-check visual evoked potential versus perimetry with blue-yellow in patients with open angle glaucoma / 国际眼科杂志(Guoji Yanke Zazhi)
In a retrospective analysis, IC-VEP, perimetry and OCT were performed on 101 subjects(<i>n</i>=35, normal; <i>n</i>=30, early glaucoma; <i>n</i>=36, moderate and advanced glaucoma)from China. The sensitivity of IC-VEP, perimetry and OCT for detection of glaucoma, as well as the agreement within these 3 methods, were calculated to evaluate their clinic performance.<p>
RESULTS:
In the early primary open angle glaucoma(POAG)group the sensitivity of IC-VEP, blue-yellow perimetry and OCT were 70.00%, 70.00% and 63.33%, respectively. In the moderate advanced POAG group, the sensitivity of IC-VEP, OCT and blue-yellow perimetry were 86.11%, 88.89% and 91.67%, respectively. The specificity of IC-VEP was 91.43%. The results of IC-VEP were highly consistent with OCT and blue-yellow visual field tests(kappa 0.721-1.000, <i>P</i><0.05).<p>
