central retinal artery

The central retinal artery is approximately 160 micrometres in diameter.

In humans, a central retinal artery is located slightly off-center in nasal direction.

Eye: an infarction can occur to the central retinal artery which supplies the retina causing sudden visual loss.

Thus if the central retinal artery gets occluded, there is complete loss of vision in that eye even though the fovea is not affected.

The patient with central retinal artery occlusion will present with sudden acute, painless loss of vision in one eye.

The fovea and a small area surrounding it are not supplied by the central retinal artery or its branches, but instead by the choroid.

The ophthalmic artery branches off into the central retinal artery which travels with the optic nerve until it enters the eye.

A carbogen mixture of 95% oxygen and 5% carbon dioxide can be used as part of the early treatment of central retinal artery occlusion.

Avoid epinephrine, commonly mixed in with local anesthetics for vasconstriction, in seeing eyes as this can cause a central retinal artery occlusion.

The cherry red spot is seen in central retinal artery occlusion, appearing several hours after the blockage of the retinal artery occurs.

This central retinal artery provides nutrients to the retina of the eye, more specifically the inner retina and the surface of the optic nerve.

Larvae are thought to enter the eye through the optic nerve, central retinal artery, short posterior ciliary arteries, soft tissues, or cerebrospinal fluid.

A cherry-red spot is a finding in the macula of the eye in a variety of lipid storage disorders and in central retinal artery occlusion.

There was little blood, but the force of the throw had driven the sharp point deep through cornea, iris and lens, clear into the central retinal artery, piercing the brain.

The central retinal artery and vein can be seen in the middle of the disc as it exits the scleral canal with the optic nerve to supply the retina.

The central retinal artery is the first, and one of the smaller branches of the OA and runs in the dura mater inferior to the optic nerve.

The central retinal artery (retinal artery) branches off the ophthalmic artery, running inferior to the optic nerve within its dural sheath to the eyeball.

This is the basis of the famous "Cherry red spot" seen on examination of the retina on funduscopy of a central retinal artery occlusion (CRAO).

In 2009, the Undersea and Hyperbaric Medical Society added "central retinal artery occlusion" to their list of approved indications for hyperbaric oxygen (HBO).

As with central retinal artery occlusions, ophthalmic artery occlusions may result from systemic cardiovascular diseases; however, a cherry-red spot is typically absent and the vision is usually worse.

The retinal circulation, on the other hand, derives its circulation from the central retinal artery, also a branch of the ophthalmic artery, but passing in conjunction with the optic nerve.

Branch retinal artery occlusion (BRAO) is a rare retinal vascular disorder in which one of the branches of central retinal artery is obstructed.

Central retinal artery occlusion (CRAO) is a disease of the eye where the flow of blood through the central retinal artery is blocked (occluded).

Conditions that affect or destroy the retina include retinal detachment; macular disease (e.g., macular degeneration); and retinal vascular occlusions, the most important of which is central retinal artery occlusion.

The central retinal artery supplies all the nerve fibers that form the optic nerve that carries the visual information to the lateral geniculate nucleus of the thalamus, including those that reach over the fovea.
