BACKGROUND: Traffic police personnel are chronically exposed to vehicular emissions, environmental pollutants, and ultraviolet radiation, which may adversely affect their ocular health.
AIM: To evaluate the ocular surface disorders among traffic police personnel in Puducherry, India, using clinical examination and impression cytology.
SETTINGS AND DESIGN: A cross-sectional study was conducted among traffic police personnel (n=106) in the Ophthalmology Outpatient Department of the Indira Gandhi Medical College and Research Institute, Puducherry, India.
MATERIALS AND METHODS: A comprehensive ophthalmic examination, including the Ocular Surface Disease Index Questionnaire (OSDI), Schirmer's test, tear film break-up time (TBUT), and tear meniscus height (TMH) test, was used to assess dry eye. Conjunctival impression cytology was performed to evaluate the microscopic epithelial alterations. Statistical analysis was performed using IBM SPSS Statistics for Windows, Version 21.0 (Released 2012; IBM Corp., Armonk, NY, United States). Associations were evaluated using the chi-square test, and the significance level was set at p < 0.05.
RESULTS: According to Nelson's grading, 17% of the participants showed Grade 0, 47.2% showed Grade 1, 31.1% showed Grade 2, and 4.7% showed Grade 3. A statistically significant association was observed between the Nelson grade and the years of service in active field duty, the OSDI score, and TBUT (p < 0.05). Dry eye symptoms were present in 78.3%, and work-related stress was reported by 53.8%. The defined exposure in the study was chronic exposure to pollution, dust, and ultraviolet rays for a period of more than one year, and the outcome assessed was squamous metaplasia detected by conjunctival impression cytology, which shows a clear exposure-outcome relationship.
CONCLUSION: Chronic occupational exposure to air pollution and ultraviolet radiation contributes to dry eye disease and squamous metaplasia among traffic police personnel. Regular screening and preventive strategies are recommended.
