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.

- Middle palpebral artery
- Lacrimal fascia overlying lacrimal sac (some fibers of origin of the orbicularis oculi muscle remain)
- Ampulla of superior lacrimal duct (opened)
- Superior lacrimal duct
- Medial palpebral ligament
- Medial ocular angle
- Ampulla inferior lacrimal duct (opened)
- Infraorbital margin
- Inferior oblique muscle
- Fascia of levator palpebrae superioris muscle
- Aponeurosis of levator palpebrae superioris muscle (cut off)
- Superior tarsalis muscle (cut across)
- Superior conjunctival fornix
- Bulbar conjunctiva
- Superior tarsus
- Lacrimal nerve
- Skin supporting cilia of lower lid
- Inferior tarsus
- Bulbar conjunctiva
- Fascia forming suspensory ligament of eye
