Course description: 

Fluoroscopy delivers the highest occupational radiation doses experienced by medical imaging professionals. Although fluoroscopy operators routinely wear lead aprons and other personal shielding, they might not use eye protection, making radiation exposure of the eyes a significant safety issue. Veteran medical writer Bryant Furlow, B.A., has pulled together the most comprehensive, in-depth research on eye anatomy and visual system diseases for this exceptional article. Mr. Furlow covers every aspect of radiation protection of the eye, from the changing dose thresholds for radiation cataract formation to strategies to minimize radiation dose to the eyes.

Course objectives: 

After completing this article, readers should be able to:

  • Describe the functional anatomy of the eye.
  • Explain how ionizing radiation can disrupt the structure, physiology and function of visual system tissues.
  • Discuss different types of visual system diseases and disorders and their relation to ionizing radiation exposure.
  • Discuss changing views about dose thresholds for radiation cataract formation.
  • Identify how staff position with regard to the fluoroscopy unit and patient can affect dose.
  • Describe strategies for minimizing patient and staff radiation doses during fluoroscopicprocedures.
  • Explain why fluoroscopic radiation dose to the eye lens is a major occupational exposure concern and how the threat of chronic exposure can be mitigated.
  • Describe sentinel event thresholds requiring postfluoroscopic monitoring for radiation injury.
