Leopard-like undereye

Introduction Tigroid 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, so it is called leopard-like fundus. Is a choroidal type. The degree of myopia is high, the axis of the eye is elongated, the retina is thinned, and the blood vessels under the retina become permeable, causing the fundus to look like a leopard. More common in the elderly and high myopia. Checking the fundus for this type of population can be found.

Cause

Leopard-like fundus is a typical fundus of degenerative myopia, also known as pathological myopia. As long as the degree of myopia is high, the leopard-like fundus will appear. This is because the degree of myopia is high, the axis of the eye is elongated, the retina is thinned, and the blood vessels under the retina become It is well-known to cause the eye to look like a leopard.

Ophthalmoscopy

In the elderly patients with pathological myopia, in addition to visual acuity, refractive, intraocular pressure examination, fundus examination. Fundus examination showed: the entire fundus was slightly dark gray, and the choroid was diffusely atrophied, the capillary layer and the middle blood vessels were reduced or disappeared, and the orange-red blood vessels were exposed, making the fundus a leopard skin. The leopard-like fundus is often caused by a decrease in pigmentation of the retinal pigment epithelial layer, atrophy of the choroid, disappearance of the small vascular network, and visualization of the large blood vessels, so that the fundus shows a thick stripe of reddish-brown.

Differential diagnosis

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. .

Fundus cherry erythema: due to the interruption of the fundus arterial blood supply, diffuse gray-white edema in the posterior pole of the retina, the fovea in the fundus, and the striking "cherry erythema" in the surrounding gray-white edema area.

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.

The macula was found to have gray discoloration at the fundus: Austin-type children with cerebral sulfatosis, also known as Austin-type metachromatic leukodystrophy, is a joint disease of cerebral sulphur disease and mucopolysaccharidosis. It is characterized by mild Hurler syndrome, multiple bone dysplasia, severe neurological symptoms and markedly low intelligence. Under the fundus examination, it can be found that the macula is grayish and discolored, and even blind.
