title: [Detection of HBV DNA in human tears and its contamination of the tonometer].
abstract: HBV DNA was detected by PCR in the tears of 16 (47.1%) of 34 chronic hepatitis patients, 2 of 5 asymptomatic carriers, and on the Maclakof tonometer. HBV DNA on the contact tonometer was not completely removed by wiping twice with alcohol cotton balls, and the authors suggest flushing by running tap water for 10 seconds and immersion in 2% glutaraldehyde for 10 minutes.
