Abstract

Purpose: This study was performed to determine the Color vision and Blood lead concentration in Koushk Lead and zinc mine employees. Methods: This cross-sectional study was carried out at Koushk lead and zinc mine in Bafgh city. All participants were male. They were divided into two groups: The exposed groups (114 patients) and the non-exposed groups (76 patients). According to the exclusion criteria, 190 subjects recruited for the study with complete satisfaction. A preliminary optometric examination and evolution of Color vision were performed for all subjects. Color vision was determined using the D15-Fransworth test. The concentration of blood lead was recorded based on the blood test sheet. Results: Percentage frequency of the Color vision defect was 2. 72% in the control group and 11. 55% in the case group. The difference between the average of color confusion index between the two groups both in the right eye (case: 1. 169 ± 0. 283, control: 1. 07 ± 0. 17) and the left eye (case: 1. 168 ± 0. 282, control: 1. 06± 0. 14) was statistically significant (right eye p=0. 011, left eye p=0. 002). Mean blood lead in case and control groups were 10. 07 ± 15. 81 and 6. 46 ± 9. 03, respectively. This difference was statistically significant between two groups (P = 0. 047). Conclusion: The difference between groups in the Color vision defect indicates that long-term exposure to minerals in the lead and zinc mine may cause Color vision defect and could be a potential cause of this disorder.
