Nerves passing through Superior Orbital fissure

This is one of the favorite questions of examiners and often the most confusing topic for students.I found this interesting mnemonic on net, it is wonderful as SONIA looks good but I don’t know how her liver is, so let us do an LFT and find out.


  1. Lacrimal nerve
  2. Frontal nerve
  3. Trochlear nerve
  4. Superior division of oculomotor nerve
  5. Abducens nerve
  6. Nasociliary nerve (branch of ophthalmic nerve)
  7. Inferior division of oculomotor nerve
