Central Vein Occlusion Study (1995)

Vein occlusion is likely ischemic if…

  1. Abnormal ERG
  2. +RAPD
  3. Large amounts of hemes

VA is equally as good about telling us about ischemia as IVFA.

  1. 20/200 to start –> Likely to end at 20/200 = Likely Ischemic
  2. 20/30 to start    –> Likely to end at 20/30 = Likely non‐ischemic
  3. 20/middle acuity range to start –> Can progress either way.
