| 520 | |b Background: lead is a naturally occurring toxic metal found in the earth’s crust. Its widespread use has resulted in extensive environmental contamination, human exposure and significant public health problems in many parts of the world. Aim: This study aimed to assess the effect of prolonged occupational lead exposure and the outer eye abnormalities among workers of military industrial factory as well as to assess the knowledge and practice of the workers towards lead exposure and hazards of lead poisioning. Materials and Methods: This is a comparative cross-sectional study of 100 workers selected randomly from the lead-factory, their ages ranged from 21 to 67 years with a mean age of 39.1 ± 10.3 years. They were divided into two groups according to their duration of work (duration of exposure) group of short duration (less than 10 years) and group of long duration (more than 10 years). Investigations included vision and V.A measurements using Snellen tumbling E-chart, refraction using retinoscopy, as well as examinations of the external eye, anterior segment and media using torch light with low power magnifier. Results: The finding revealed that 8% of workers of long duration had V.A less than 6/12 after best correction in place compared to 1% among workers of short duration, this difference was statistically significant (p<0.001). About 66% of long duration group presented with symptoms of irritated eye (foreign body sensation and tearing, itching and burning sensation and periodic redness) compared to 18% among group of short duration with a significant association (p= 0.038). Almost 36% of workers of long duration had an ocular sign of conjunctival discoloration (gray-bluish conjunctiva) compared to 10% among workers of short duration with a significant association (p = 0.004). Anterior segment examination revealed that the majority 83% of workers in group of long duration had conjunctival disorders of (pterygium 77% and allergic conjunctivitis 6%) compared only to 25% among group of short duration (pterygium 23% and 2% allergic conjunctivitis) which was significantly associated (p = 0.01). The media examination showed that 14% of long duration workers had cataract, 2% had corneal opacity and 2% were pseudophakic, while surprisingly none of workers in group of short duration had any of those media abnormalities, which was statistically significant (p=0.04). With regard to knowledge of the workers about the effect of the lead poison on the eye only 30% of respondents were knew that the lead poison had effect on ocular health therefore the most of them not use the protection tools. Conclusion: Chronic Occupational lead exposure have a great effect on vision and eye health of the workers, its lead to reduce vision as result development of amblyopia, it also had affected on the ocular media as well as causes severe allergic reaction. Thus, all the workers in this field should wear the protection tools that provided in the factory and there is critical need for examining their ocular heath annually. | ||
