Reducing Radiation Damage to Eyes
In a paper presented at The Radiological Society of North America (RSNA) in December 2004, specific findings were reported of radiation related eye damage in a group of 59 practicing interventional radiologists, ranging in age from 29 to 62, who were surveyed and examined.
“The researchers found that nearly half of the interventional radiologists screened had signs of radiation related lens changes. PSC cataracts were found in five (8%) of the 59 radiologists screened and 22 subjects (37%) showed small paracentral dot-like opacities in the PSC region of the lens, which is consistent with early signs of radiation damage.”
The ionizing radiation associated with fluoroscopy in interventional and diagnostic imaging procedures can have damaging biological effects on many types of body tissue. Sometimes these effects take years to manifest themselves, in the form of conditions that can lead to impaired vision and even blindness. This delayed manifestation makes it difficult to recognize the harmful effects of radiation until the damage has already been done. Dosimetry studies have proven that x-ray protective glasses can effectively eliminate 90% of the scattered radiation to the eye.
