The incidence of hepatitis B virus infection has been increasing every year in the United States, particularly among medical personnel. Only half of these cases are associated with exposure to blood or blood products. Respiratory, fecal-oral, and venereal methods of transmission of hepatitis B virus infection are supported by epidemiological evidence and by the demonstration of hepatitis B surface (HBsAg) antigen in several body secretions. In this investigation, tears were collected from patients whose serum was positive for HBsAg. These tears were tested for the same antigen, which was found to be present in half the cases. There is a risk of transferring hepatitis B virus infection by tonometers or soft contact lenses contaminated by HBsAg.
在美国，乙型肝炎病毒感染的发病率逐年上升，在医务人员中尤为如此。这些病例中只有一半与接触血液或血液制品有关。乙型肝炎病毒感染的呼吸道、粪-口和性传播途径有流行病学证据以及在多种身体分泌物中检测到乙型肝炎表面（HBsAg）抗原的支持。在这项调查中，从血清HBsAg呈阳性的患者中采集了眼泪。对这些眼泪进行了相同抗原的检测，发现半数病例中存在该抗原。存在通过被HBsAg污染的眼压计或软性隐形眼镜传播乙型肝炎病毒感染的风险。
