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
