Popis: We performed simultaneous measurement of herpes simplex virus (HSV) DNA by real-time polymerase chain reaction (real-time PCR) and of HSV-specific secretory IgA antibody (HSV-sIgA) by enzyme-linked immunosorbent assay (ELISA) in tears obtained using Schirmer strips in order to investigate its diagnostic efficacy for herpes simplex keratitis (HSK). A total of 59 affected eyes from 59 patients with clinically suspected HSK (HSK group) and 23 eyes from 23 healthy volunteers (control group) were enrolled in this study. The HSK group was divided into five subgroups: dendritic/geographic keratitis, disciform keratitis, necrotizing keratitis, atypical keratitis, and others. The tear samples were taken using Schirmer strips to determine the HSV DNA and HSV-sIgA levels. The overall sensitivity and specificity were 55.8 and 100 % for HSV DNA and 49.2 and 82.6 % for HSV-sIgA. The HSV DNA levels in the disciform keratitis subgroup (median, 3.1 × 102 copies/sample) were significantly lower than those in the dendritic/geographic keratitis subgroup (median, 2.3 × 104 copies/sample) (P
