Under eye cherry red spot

Introduction Due to the interruption of the fundus arterial blood supply, diffuse gray-white edema appeared in the posterior pole of the retina, and the fovea of the fundus was in the fovea. Under the foil of the surrounding gray-white edema area, it showed a striking "cherry erythema". Often due to interruption of the fundus arterial blood supply. Senile fundus arteriosclerosis is a chronic fundus vascular change common in the elderly over 60 years old. It is mainly characterized by thinning of the fundus arteries, decreased transparency, light color, strong light reflectivity, straight blood vessels, and branches into acute angles. It is a manifestation of aging. People with senile fundus arteriosclerosis do not have to be nervous because it is generally not blind.

Differential diagnosis

Symptoms of erythema erythema in the fundus:

Leopard-like fundus: Because the pigment of the retinal pigment epithelium is less, the pigmented area of the choroidal macrovascular structure and the vascular space can be seen through the retina, which is similar to the texture of the leopard skin. It is called the leopard-like fundus and belongs to the choroid type. Fundus examination is often caused by pigmentation of the retinal pigment epithelial layer, choroidal atrophy, disappearance of small vascular network, large blood vessels can be seen, and the fundus shows a thick stripe of reddish brown.

Sunset-like or eve-like fundus: late in the field of exudative choroiditis, choroidal pigment cells and retinal pigment epithelial cells are severely damaged and lost, and the fundus is red when the sun sets, called the evening glow or the evening sun. .

Cherry red spots on the macula of the fundus: Niemann-Pick's disease (NPD) is an inherited metabolic disease caused by sphingomyelin and cholesterol deposited in various organs of the body. The main features of the splenomegaly, the red spot on the macula of the fundus, and the large foam-like cells in the bone marrow smear.
