What Is Choroiditis?

Choroiditis is a type of post uveitis. Because choroidal blood vessels originate from the short posterior ciliary arteries, they can develop independently. But because it is close to the retina and supplies blood to the outer layer of the retina, it often involves the retina and is associated with chorioretinitis. In the early stage of inflammation, the photoreceptor cells of the retina are stimulated, and there may be a flash of light in front of the eyes. When the inflammatory products enter the vitreous body, the vitreous body appears cloudy, with black spots floating in front of the eyes, and the visual acuity decreases to varying degrees.

Clinical manifestations of choroiditis

Symptoms

It mainly depends on the type of inflammation, the affected area and the severity. There may be dark shadows or dark spots in front of eyes, flashes, blurred or decreased vision, etc. Combined with systemic diseases, there are corresponding systemic symptoms.

2. Signs

Common are:

(1) Inflammatory cells and turbidity in the vitreous;

(2) Focal choroidal retinal infiltrates, which may be inconsistent in size, form scar lesions at a later stage;

(3) Retinal vasculitis with vascular sheath, vascular occlusion, and bleeding;

(4) Edema of the retina or macular.

In addition, exudative retinal detachment, proliferative retinopathy, and vitreous hemorrhage can occur. Occasionally, mild anterior chamber flashes, small amounts of anterior chamber inflammatory cells, etc. may appear.

Choroiditis examination

Check that the outer eye is normal. Under the ophthalmoscope, you can see that the dots and flocs in the vitreous body are suspended and move against the direction of eyeball rotation. In the acute phase, there were yellowish white, patchy exudation, and some fusion. The lesion was slightly raised, which was due to choroidal vasodilation and enhanced permeability, which caused localized edema and cell infiltration. The retina can also be affected in the corresponding part of the lesion. After the lesion is absorbed, there is no trace in mild cases, and pigment loss or reproduction occurs in severe cases due to pigment epithelial lesions. Exposure, forming a typical black and white atrophic spots.

Choroiditis diagnosis

A diagnosis can be made based on typical clinical manifestations. FFA is very helpful for judging the retina and its vasculitis and choroidal pigment epithelial lesions. ICGA (Indocyanine Green Fundus Angiography) is helpful to determine the lesions of the choroid and its blood vessels. Serological examination, direct smear examination of intraocular fluid pathogens, polymerase chain reaction determination of infectious agent DNA, pathogen culture, antibody determination, etc., are helpful for the diagnosis of the cause.

Choroiditis Treatment

1. Treat the primary disease and remove the cause.

2. Corticosteroids: Prednisone (prednisone) 0.5 to 1 mg per kilogram of body weight per day, taken at 8 am every day, while supplemented with potassium chloride orally, pay attention to check the ion changes in the blood regularly. If you want to strengthen the local drug concentration, you can use dexamethasone 2.0 mg and torasulin 12.5 mg after injection, once a week.

3. Use immunosuppressive and non-hormonal anti-inflammatory drugs and antibiotics.

4. Systemic medications, such as vasodilators, energy mixtures, and vitamins.
