Abstract

BACKGROUND:

Recent studies have reported a significant increase in eye lens opacities among staff in the cardiac catheterization laboratory but indicated further studies are needed to confirm the findings.

OBJECTIVE:

To evaluate the prevalence of opacities in eyes of cardiologists, radiographers and nurses working in interventional cardiology.

METHODS:

The eyes of 52 staff in interventional cardiology facilities and 34 age- and sex-matched unexposed controls were screened in a cardiology conference held in Kuala Lumpur by dilated slit-lamp examination, and posterior lens changes were graded. Individual cumulative lens X-ray exposures were calculated from responses to a questionnaire in terms of workload and working practice.

RESULTS:

The prevalence of posterior lens opacities among interventional cardiologists was 53%, while in nurses and radiographers it was 45%. Corresponding relative risks were 2.6 (95% CI: 1.2-5.4) and 2.2 (95% CI: 0.98-4.9), for interventional cardiologists and support staff, respectively.

CONCLUSIONS:

This study confirms a statistically significant increase in radiation-associated posterior lens changes in the eyes of interventional cardiology staff.
