Dissection of left orbit from an anterior approach
Bulbar conjunctiva; lacrimal canaliculi opened
The palpebral conjunctiva has been removed from both eyelids to expose the conjunctival fornices and bulbar conjunctiva. The tarsal plates, medial and lateral palpebral ligaments and lacrimal canaliculi remain in place. The canaliculi have been opened (5,9) to reveal their ampullae.
  1. Supratrochlear nerve
  2. Superior oblique muscle
  3. Middle palpebral artery
  4. Lacrimal fascia overlying lacrimal sac (some fibers of origin of the orbicularis oculi muscle remain)
  5. Ampulla of superior lacrimal duct (opened)
  6. Superior lacrimal duct
  7. Medial palpebral ligament
  8. Medial ocular angle
  9. Ampulla inferior lacrimal duct (opened)
  10. Infraorbital margin
  11. Inferior oblique muscle
  12. Fascia of levator palpebrae superioris muscle
  13. Aponeurosis of levator palpebrae superioris muscle (cut off)
  14. Superior tarsalis muscle (cut across)
  15. Superior conjunctival fornix
  16. Bulbar conjunctiva
  17. Superior tarsus
  18. Lacrimal nerve
  19. Skin supporting cilia of lower lid
  20. Inferior tarsus
  21. Bulbar conjunctiva
  22. Fascia forming suspensory ligament of eye
