Ionizing radiation (IR) is a risk factor now recognized by lens opacity, with posterior subcapsular cataract (PSC) being the most described tissue reaction. Over the past 20-30 years, the number and complexity of the procedures have made interventional cardiologists (IC) more exposed to IR. Our objective was to evaluate if there is a prevalence of cataracts in IC and other professionals working in the area of hemodynamics in Latin America that could be correlated with their professional activity.
CI and workers exposed to IR (G1) after signing the informed consent term were subjected to a slit lamp examination to evaluate the lens during Solaci-2016. The findings were described and classified by ophthalmologists in the degree of opacity and location through the opacity lens classification system II (LOCS II). Clinical cardiologists and health professionals who are not exposed to IR (G2 control group), after signing the informed consent, also underwent an examination by the same professionals. Both groups responded to a questionnaire about working and health conditions to eliminate risk factors for cataracts. The two groups compared the ophthalmologic findings using the chi-square test. A significance level of 5% (p <0.05) was used.
A total of 140 volunteers (G1) with a mean age of 44.95 (10.23) years and 88 volunteers (G2 control) with a mean of 48.07 (12.18) years. Of these, 75.2% (G1) and 85.2% (G2) were the physicians. Statistical analysis between G1 and G2 resulted in a prevalence of cataracts in the G1 group of 30% compared to G2 16% (p = 0.0161), PSC present in 11% and 2% G2 (p = 0.0126). Considering only physicians, 35% had cataract prevalence in G1 and G2 in 15% (p = 0.0022), PSC 13% and 3% (p = 0.0149), respectively. In the group of non-medical professionals there was no prevalence of statistically significant results.
Cataract was found in the most professional group exposed to RI, statistically more frequent in the IC group. PSC associated with cortical changes were most frequently found to be damages which shows the correlation between the risk of this type of damage to occupational exposure to RI among interventional cardiologists in Latin America.
