A. Pitkaranta et al., Detection of human herpesvirus 6 and varicella-zoster virus in tear fluid of patients with Bell's palsy by PCR, J CLIN MICR, 38(7), 2000, pp. 2753-2755
Human herpesvirus 6 DNA was detected by PCR in the tear fluid of 7 (35%) of
20 patients with Bell's palsy and of 1 (5%) of 20 healthy controls. Varice
lla-zoster virus was detected by PCR in the tear fluid of 2 of 20 Bell's pa
lsy patients but in none of the tear fluids from 20 healthy controls. These
findings suggest an association between human herpesviruses and Bell's pal
sy.
