RESUMO
OBJECTIVE@#To establish an acuity inspection system with sweep pattern visual evoked potential (SPVEP) so as to provide the evidence for acuity objective inspection.@*METHODS@#Based on the domestic sweep pattern visual evoked apparatus, sections of hardware were reformed and a manipulation program possessing false random control software was compiled. The SPVEP acuity for the 78 eyes (10 normal eyes, 10 ametropia eyes, 48 prevalence eyes, 10 false ametropia eyes) was estimated with our acuity objective inspection system, then compared with the E visual acuity of those eyes by statistical procedure.@*RESULTS@#There was a close correlation between the SPVEP acuity and E visual acuity for 78 eyes (r2 = 0.946).@*CONCLUSION@#SPVEP acuity inspection system can be applied to estimate objective acuity.
