b. What are the underlying causes of this condition? (50%)

CRVO

Answer

FACEM VAQ Exam 20095.2 – Question 8

  • Overall pass rate for this question was 48/56 (85.7%).
  • The image of the retina suggests retinal vein occlusion
  • The examiners expected that candidates would highlight in their description the features of central retinal vein occlusion seen in the image such as venous tortuosity and retinal haemorrhages
  • The second part of the answer needed to make clear that this was an atherosclerotic/clotting process (and not an embolic one) and as such the causes were the systemic causes of these processes.
  • Failing answers did not identify this as a central retinal vein occlusion or incorrectly described it as an embolic phenomenon.
