About Belcolore

The BELCOLORE study will cover the Belgian part of a large-scale European study and will involve the recruitment of interventional cardiologists and electrophysiologists in Belgian hospitals.

Twelve European countries will participate to the European joint epidemiological project EURALOC by recruiting interventional cardiologists following the same protocol. This will ensure the comparability of information and the possibility to pool all data in one large European cohort for joined analysis.

Interventional cardiologists and electrophysiologists are professionals at risk because the eyes are daily exposed to ionising radiation. Despite the significant incidence of early lens opacities among cardiologists [1,2,3,4], several issues regarding the relationship between radiation dose, lens opacities and cataract development remain unclear and there is an urgent need for a large-scale and high-quality epidemiological study on radiation induced lens opacities.
