Dry eye disease as an occupational risk factor in operating room nurses

Knowing occupational risks in a multifactorial disease such as dry eye disease is important for disease diagnosis and treatment. Dry eye disease (DED) is a multifactorial disease of the ocular surface characterised by tear film instability, adversely affecting visual function and quality of life. The operating room environment has many risk factors for DED such as air conditioning, constant humidity, constant room temperature, intense lighting, surgical smoke, anaesthetic gases and irritating chemicals, and prolonged mask use. This study investigates the ocular surface findings and blink patterns of operating room nurses at risk of DED. A total of 68 nurses (operating room, n = 34; outpatient clinic, n = 34) were included in this study. The diagnosis of DED was assessed using a questionnaire, best-corrected visual acuity, tear break-up time, corneal fluorescein staining, meibomian gland assessment, Schirmer I test. All the tests were conducted in the same area. According to the ocular surface disease index, the rate of dry eye symptoms was significantly higher among operating room nurses than among outpatient nurses (70.5% vs 41.1%). Severe dry eye symptoms were more common in the operating room group. The meibomian gland score was higher in the operating room group (29.4% vs 5.9%). The numbers of blinks (30.91 ± 12.81 vs 21.05 ± 7.77) and incomplete blinks (8.76 ± 4.68 vs 5.76 ± 3.20) at rest were higher in operating room nurses. The occupational risk for DED was high among operating room staff. National and international standards for the prevention and management of DED in personnel involved in health care services are needed.
