Objective
To study the effect of long-term low dose ionizing radiation on ocular lens opacities.
Methods
With random cluster sampling, the residents aged over 45 years were selected from two villages in high background radiation areas(HBRA) in Yangxi County and three control areas in Enping County in Guangdong province, and a questionnaire survey was conducted and slit-lamp eye lens opacity was checked.
Results
With adjustment of gender, age, smoking and drinking factors compared with the residents living in control areas, the risks of eye lens opacities, cortical opacities, nuclear opacities and posterior subcapsular opacities for residents living in HBRA were 0.99 (95%CI: 0.72-1.37), 1.45 (95%CI: 0.99-2.11), 0.82 (95%CI: 0.60-1.14), and 4.05 (95%CI: 1.56-10.46), respectively.
Conclusions
Long-term low dose ionizing radiation exposure is probably an important risk factor for eye posterior subcapsular lens opacities.
