Central exudative chorioretinitis

Introduction to central exudative chorioretinitis This disease is also known as Rieger central retinitis, young hemorrhagic macular degeneration. This disease is an arc-like exudative chorioretinal lesion that occurs in and around the macula, accompanied by subretinal neovascularization and hemorrhage. It is not uncommon in clinical practice. It is usually monocular, and the age is below 50 years old. Decreased, with central dark spots and visual distortion as the main symptoms. The course of disease is half a year to one year, and it is relieved by itself within half a year. The main clinical manifestations of this disease are central vision loss, central dark spots, visual distortion, anterior segment and vitreous non-inflammatory changes, fundus yellow-gray exudative lesions and hemorrhage in the macula, round or oval, border not Clear, slightly raised, about 1/4 to 3/2 disc diameter (PD), more common than 1PD. basic knowledge The proportion of illness: 0.3% Susceptible people: no specific population Mode of infection: non-infectious Complications: choroidal hemorrhage

The cause of central exudative chorioretinitis

The etiology of this disease has not been known so far, and most scholars believe that it is related to factors such as toxoplasmosis, histoplasmosis, amebiasis, piriflagellate, toxoplasmosis, syphilis and tuberculosis.

The pathogenesis of this disease is considered by some scholars to be caused by macular hemorrhage and exudation due to the invasion of new blood vessels originating from the subretinal choroid.

Central exudative chorioretinitis prevention

The disease causes macular damage due to inflammation, so the visual prognosis is poor. The key is early treatment, and looking for pathogenic factors to treat systemic diseases while treating eye diseases. Pay attention to rest during the acute phase. When a new blood vessel is found through fundus fluorescein angiography, it is best to perform laser treatment. Through comprehensive measures to promote the absorption of exudation and hemorrhage, some cases can restore better vision due to early treatment.

Central exudative chorioretinitis complications Complications choroidal hemorrhage

Associated with subretinal neovascularization and bleeding. General surgical treatment can cause complications such as yellow spot, choroidal hemorrhage, subretinal neovascularization, and macular scar. Choroidal fulminant hemorrhage is a rare complication of endoscopic surgery. Choroidal hemorrhage is critical and the consequences are extremely serious.

Central exudative chorioretinitis symptoms Common symptoms Visual field changes Point bleeding Bleeding Deformation Fundus changes visual impairment

1. Symptoms: The central vision is reduced and the object is deformed.

2, fundus changes: gray spots or gray-yellow oozing lesions of the macula, round or oval, unclear borders, slightly uplifted, about 1/4 to 1 nipple diameter, curved around the lesion or Ring hemorrhage and hard lipid exudation, and may be accompanied by shallow retinal detachment of the posterior pole, late lesion absorption, scar tissue formation.

3. The visual field inspection has a central dark spot.

4, fluorescent angiography: visible from the choroidal pigment epithelium or neuroepithelial neovascularization, peripheral bleeding forms a fluorescent shadow.

The main clinical manifestations of this disease are central vision loss, central dark spots, visual distortion, anterior segment and vitreous non-inflammatory changes, fundus yellow-gray exudative lesions and hemorrhage in the macula, round or oval, border not Clear, slightly raised, about 1/4 to 3/2 disc diameter (PD), more common than 1PD.

There are curved or ring-shaped hemorrhage at the edge of the lesion, occasionally a point-like hemorrhage in the radial arrangement. There is a pigmented disorder in the periphery of the lesion. Many cases have shallow discoid retinal detachment, and some have hard lipid exudation around. Most of them are centered on the fovea, with a radius of 1PD. At the end of the disease, yellow-white scars are formed in the macular area, and fluorescein angiography is performed. In the early arterial or arterial phase, there are granular, lace-like, etc. in the exudate. There are many forms of neovascular network, the hemorrhage area obscures the fluorescence, the upper edge of the hemorrhage has a translucent fluorescent area, and the late neovascularization has a fluorescein leakage to form a strong fluorescent area.

Central exudative chorioretinitis

1. The field of vision has a dark center.

2. Fundus manifestations are limited to exudation of edema in the macula and crescent or round bleeding at the edge of the source.

3. Fluorescein angiography can be seen in the macular neovascularization.

Diagnosis and diagnosis of central exudative chorioretinitis

diagnosis

Diagnosis can be based on medical history, clinical symptoms, and laboratory tests.

Differential diagnosis

It needs to be differentiated from diseases such as uveitis in the middle and central serous chorioretinopathy.
