The cherry red spot is seen in central retinal artery occlusion, appearing several hours after the blockage of the retinal artery occurs. [4] The cherry red spot is seen because the macula receives its blood supply from the choroid, supplied by the long and short posterior ciliary arteries , while the surrounding retina is pale due to retinal ...
The entire retina (with the exception of the fovea) becomes pale and swollen and opaque while the central fovea still appears reddish (this is because the choroid color shows through). 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).
The macula (/ˈmakjʊlə/) [1] or macula lutea is an oval-shaped pigmented area in the center of the retina of the human eye and in other animals. The macula in humans has a diameter of around 5.5 mm (0.22 in) and is subdivided into the umbo, foveola, foveal avascular zone, fovea, parafovea, and perifovea areas.
Cherry red spot in a person with central retinal artery occlusion. Central retinal artery occlusion is characterized by painless, acute vision loss in one eye. [1] Upon fundoscopic exam, one would expect to find: cherry-red spot (90%) (a morphologic description in which the normally red background of the choroid is sharply outlined by the swollen opaque retina in the central retina), retinal ...

Cherry-red spot as seen in the retina in Tay–Sachs disease. The fovea's center appears bright red because it is surrounded by a whiter than usual area. Specialty: Medical genetics: Symptoms: Initially: Decreased ability to turn over, sit, or crawl [1] Later: Seizures, hearing loss, inability to move [1] Usual onset: Three to six months of age ...
Photograph of the retina of the human eye, with overlay diagrams showing the positions and sizes of the macula, fovea, and optic disc. Perifovea is a region in the retina that circumscribes the parafovea and fovea and is a part of the macula lutea. [1] The perifovea is a belt that covers a 10° radius around the fovea and is 1.5 mm wide.
