ophthalmic vein การใช้

• This is possible because of venous communication ( via the ophthalmic veins ) between the facial vein and the cavernous sinus.
• The angular vein is linked with the cavernous sinus by the superior and inferior ophthalmic veins which are devoid of valves.
• Because of its connections with the facial vein via the superior ophthalmic vein, it is possible to get infections in the cavernous sinus from an external facial injury within the Danger area of the face.
• Rarely, when infections of the canine space erode into the infra-orbital vein or the inferior ophthalmic vein ( via the sinuses ), there can be spread via the common ophthalmic vein through the superior orbital fissure and into the cavernous sinus.
• Rarely, when infections of the canine space erode into the infra-orbital vein or the inferior ophthalmic vein ( via the sinuses ), there can be spread via the common ophthalmic vein through the superior orbital fissure and into the cavernous sinus.
• One of these passes through the inferior orbital fissure and joins the pterygoid venous plexus, while the other enters the cranium through the superior orbital fissure and ends in the cavernous sinus, either by a separate opening, or more frequently in common with the superior ophthalmic vein.
• Previous to its junction with the frontal vein, it sends through the supraorbital notch into the orbit a branch which communicates with the ophthalmic vein; as this vessel passes through the notch, it receives the frontal diploic vein through a foramen at the bottom of the notch.
• It transmits the oculomotor nerve, the trochlear nerve, and the abducent nerve, the three branches of the ophthalmic division of the trigeminal nerve, some filaments from the cavernous plexus of the sympathetic nervous system, the orbital branch of the middle meningeal artery, a recurrent branch from the lacrimal artery to the dura mater, and the ophthalmic vein.
• It transmits to the orbital cavity the oculomotor, the trochlear, the ophthalmic division of the trigeminal, and the abducent nerves, some filaments from the cavernous plexus of the sympathetic, and the orbital branch of the middle meningeal artery; and from the orbital cavity a recurrent branch from the lacrimal artery to the dura mater, and the ophthalmic veins.
