Ophthalmic artery Flashcards
first intracranial branch of internal carotid artery
Ophthalmic Artery
first intra-orbital or intra-cranial branch which ENTER THE OPTIC NERVE
Central Retinal artery
supplies sclera, choroid, ciliary body, and iris
Ciliary Arteries
arises as 2-3 groups of 6-8 vessels
Posterior Ciliary Artery PCA
Branches of PCA:
short PCA
long PCA
pierced the sclera in a ring around the optic nerve
enter the choroid directly in posterior segment
short PCA
pass forward to pierced the sclera then lie between the choroid and sclera in
peri-choroidal space of Schwalbe
Long PCA
Greater Iris circle or Circulus iridis major is formed by _______
union of:
2 long PCA - 7 ACA
partially supplies the LR muscles
Lacrimal Artery
Major blood supply to the Anterior Uvea
Anterior Ciliary artery ACA
branches of muscular arteries:
lateral branch - SR, LR, SO, LPS
medial branch - MR, IR, IO
Supply the skin of forehead & scalp:
Supra-trochlear Artery
Orbital Branches of Ophthalmic arteries:
Lacrimal
Supra-orbital
Supra-trochlear
Palpebral
Nasal
Ocular branches of Ophthalmic arteries:
Ciliary arteries:
CRA
ACA
PCA - short PCA, long PCA,
Muscular Arteries - lateral MA, medial MA
