About the webinar
Radiation induced eye lens opacities have been found in one third to half of the operators in interventional suites primarily among interventional cardiologists (ICs) but this may apply to interventional radiologists, electro-physiologists and vascular surgeons as well, who perform similar magnitude of work as ICs. Nurses in interventional suites who stay inside for most of the time when radiation beam is ON have been shown to have lens opacities. Data among other category of medical professionals like orthopaedic surgeons, urologists, gastroenterologists and anaesthetists is awaited but lack of use of protective means that is common, tends to indicate that they too may have significant risk.
Most studies so far have shown lens opacities rather than frank cataract, but data from A Bomb survivors indicates that lens opacities have the potential to lead to cataract after several years of latent period. There is great momentum currently in large part of the world in this area.
While the risk is real, the avoidance is also a real possibility. International Commission on Radiological Protection (ICRP) has reduced dose limits for occupational exposure for the eyes from 150 mSv/year to 20 mSv/year and this has ben adopted by the IAEA and many countries.
Learning objectives
To understand difference between lens opacities, cataract and difference between radiation induced cataract and cataract from other sources
To learn about difference in risks to those present in interventional suites
To learn about the latest recommendations of international organizations on radiation dose limit
