What causes a cherry red macula?
The appearance of a cherry red spot can result from retinal edema most commonly due to central retinal artery occlusion or traumatic retinal ischemia, which cause the perimacular tissue of the retina to appear translucent, while the fovea maintains its normal color.
What is a cherry red macula?
A cherry-red spot refers to a red-tinted region at the center of macula surrounded by retinal opacification. Cherry-red spots may be present in a variety of pathologic conditions, including lysosomal storage disorders, retinal ischemia, and retinal infarction.
What is the cherry red spot in retinal artery occlusion?
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. It describes the appearance of a small circular choroid shape as seen through the fovea centralis.
Does Gaucher have cherry red spot?
The commonest conditions associated with cherry-red spots include neuronal ceroid-lipofuscinosis, Farber lipogranulomatosis, galactosialidosis, Gaucher’s disease, GM1 and GM2 gangliosidoses, metachromatic leukodystrophy, Niemann-Pick type A and B, Sandhoff’s disease, and sialidoses type 1, 2, and 3 (Chapter 17 for …
What artery supplies macula?
In approximately 15% of the population, the short posterior ciliary arteries give off one or more cilioretinal arteries to supply the inner two-thirds of the macula in addition to the central retinal artery.
Does Gaucher disease have cherry red macula?
The differential diagnosis of a cherry red spot in the macula includes central retinal artery occlusion and metabolic storage diseases such as Tay-Sachs disease, Sandhoff disease, Niemann-Pick disease, Fabry disease, Gaucher disease, and sialidosis.
What artery supplies the macula?
Causes. The favored explanation for why the center visual field is preserved after large hemispheric lesions is that the macular regions of the cortex have a double vascular supply from the middle cerebral artery (MCA) and the posterior cerebral artery (PCA).
How is CRAO treated?
Table 1: Treatment Options for CRAO
| TREATMENT | MECHANISM OF ACTION |
|---|---|
| IV methylprednisolone | Reduce retinal edema, only given in arteritic CRAO |
| IV or intra-arterial recombinant tissue plasminogen activator (rt-PA) | Thrombolytic therapy to dissolve clot |
| Hyperbaric oxygen therapy | Increase blood oxygen tension |
| Surgery/Procedures |
How is Tay-Sachs diagnosed?
To confirm that your baby has Tay-Sachs disease, your doctor will ask you about the child’s symptoms and any hereditary family disorders and will order a diagnostic blood test. The blood test checks the levels of an enzyme called hexosaminidase in the child’s blood. The levels are low or absent in Tay-Sachs disease.
What organelle does Tay-Sachs disease affect?
Tay-Sachs is an autosomal recessive disease caused by mutations in both alleles of a gene (HEXA) on chromosome 15. HEXA codes for the alpha subunit of the enzyme β-hexosaminidase A. This enzyme is found in lysosomes, organelles that break down large molecules for recycling by the cell.
What is the difference between the fovea and the macula?
Fovea vs. The macula is the center portion of the retina that produces even sharper vision with its rods and cones. The fovea is the pit inside the macula with only cones, so vision can be at its sharpest.

What is the prevalence of cherry red spot in Sandhoff disease?
A cherry-red spot is present in approximately 90% of the patients affected with the disease. Sandhoff disease or GM2 gangliosidosis type 2 is due to mutation of the beta subunit of hexosaminidase at chromosome 5q13. Reports describe infantile, juvenile, and adults forms.
