Conjunctivitis in clean room workers. Nursing evaluation and intervention

Conjunctivitis, in the industrial setting, can be attributed to eye contact with contaminated microscope oculars. Establishing a simple, convenient process for cleaning microscope oculars as well as educating employees and their management is important to reduce risk of contamination. Early identification and treatment of an isolated infection by the occupational health nurse and temporary exclusion from microscope work is essential in controlling the spread of infection and preventing a potential epidemic. The occupational health nurse plays a pivotal role in the recognition of and response to workplace health concerns and development of targeted strategies to promote and maintain health in the workplace.

Ocular infections and the industrial use of microscopes

A cluster of ocular infections occurred in one area of a computer fabrication facility that relied on the use of industrial microscopes. A questionnaire was administered to all employees in this area. Microscope oculars were cultured and compared with control microscopes from a nonindustrial setting. Risk of infection was correlated with the number of hours of microscope use per day and subjective indicators of cleanliness. Bacterial cultures confirmed increased colony counts in industrial oculars compared with control oculars. Hygienic practices were instituted similar to those employed in medical settings. No further outbreaks of conjunctivitis have been reported in a 1-year follow-up.
