Content of the video: • 0:00 Introduction • 0:53 Mnemonic for Ophthalmic Artery • 0:59 Dorsal Nasal • 1:19 Central Retinal Artery • 1:42 Muscular Branches • 2:12 Long and Short Posterior Ciliary Arteries • 2:22 Ocular Circulation • 4:06 Anterior/Posterior Ethmoidal Artery • 5:31 Blood Supply of the Eyelids • 5:49 Ophthalmic Vein • ------------------------------- • 🫀 Join: / @taimtalksmed • 📷 Follow my IG: / taimtalksmed • 💝 Donation link: https://www.buymeacoffee.com/taimtalk... • ------------------------------- • Mneumonic for Ophthalmic Artery: DR MCLESSI • D: Dorsal Nasal Artery - communicates with the angular artery of the facial artery • R: Central Retinal Artery - Supply the Retina • M: Muscular branch of ophthalmic artery: supply extraocular muscles, and give off: • ○ Anterior ciliary artery • § Give off a conjunctival branch for the vascular zone of the conjunctiva • § Give off a branch for major arterial circle • C: Long and Short Posterior Ciliary Artery: • pierces the eye from the backside, lies in the choroid, and forms the major arterial circle MAC and minor arterial circle (intramuscular arterial circle) IMC • L: Lacrimal artery: supplies the lacrimal gland • ○ Lateral palpebral artery • E: Ethmoidal artery • ○ Anterior ethmoidal artery • § Goes to anterior cranial fossa and supplies the anterior meninges, then goes down through the cribriform plate to the nasal cavity • ○ Posterior ethmoidal artery • S: Supraorbital artery: Supraorbital foramen to the forehead, anastomose with frontal branch of superficial temporal artery • S: Supratrochlear artery: Frontal Foramen - for skin and muscles of the forehead • I: Internal or Medial palpebral artery • Ocular Circulation : • Major Arterial Circle of Iris (MAC) • ○ Formed by the Long Posterior Ciliary artery and branch of the anterior ciliary artery. • ○ MAC supplies the Iris and ciliary processes • Intramuscular arterial circle (ICM) • ○ Formed by the branch of the anterior ciliary artery and the short posterior ciliary artery • ○ Supply outer and posterior part of the ciliary muscles • Nasal Blood Supply : • Anterior Ethmoidal Artery • Posterior Ethmoidal Artery • Sphenopalatine artery • Greater palatine artery • Superir Labial Artery • They anastomose at the nasal septum and form Little's Area or Kisselbach's area, which is the area you nosebleed from. • • Blood supply of the eyelids: • Superior Palpebral Arch and Inferior Palpebral Arch are formed by: • ○ Medial Palpebral Artery • ○ Lateral Palpebral Artery (from Lacrimal Artery) • Ophthalmic Vein: • Superior Ophthalmic Vein - communicates with the angular vein as nasofrontal vein • ○ Central retinal vein for the retina • Inferior Ophthalmic Vein - communicates with the angular vein • ○ Give off Branch for the pterygoid plexus • ○ Give off a branch for the superior ophthalmic vein • Varicose veins (2 superior and 2 inferior) - contribute to the major arterial circle and intramuscular arterial circle in the choroid
