Uveitis

Introduction Uveitis is also called uveitis. The uveal membrane is composed of three parts: the iris, the ciliary body and the choroid. When a part of the uvea is inflamed, it can affect each other and affect each other.

Cause

The cause of ocular uveitis:

(1) External causes: refers to eyeball trauma, contusion, perforation injury, acute inflammation, etc., bacteria are brought into the eye and cause uveal infection. There are also toxic chemicals that can cause uveitis.

(2) Internal cause: uveal infection caused by lesions in other parts of the body. It can be a direct infection of bacteria, or it can be an antigenic reaction of certain infectious substances. These two different pathogenic factors have different clinical manifestations, so they can be divided into granulomatous and non-granulomatous uveitis. Two major categories. 1 granulomatous uveitis. Often invade the entire uveal tissue, the incidence is slow, and the white surface of the iris can appear small nodules. Common causes of this disease are tuberculosis, syphilis, herpes simplex virus or rickettsia infection; mold, parasites (such as nematodes, mites, etc.), brucella, and leprosy, leptospirosis infection. 2 non-granulomatous uveitis. It occurs mostly in the iris and ciliary body and is currently considered to be a local tissue allergic reaction (bacterial allergic reaction). The clinical manifestations are sudden onset, heavier pain, but no granulomatous nodules.

(3) secondary causes: the occurrence of inflammation in the adjacent tissue of the eye (such as inflammation of the cornea, sclera, retina) or inflammation of the orbital tissue. There are also intraocular tumors, hemorrhage, retinal detachment, and lens protein allergic reactions, which can cause uveitis.

Examination and diagnosis of ocular uveitis:

Ophthalmologic examination: visual acuity: right eye 0.1 left eye: 0.2 double external eye without obvious hyperemia, corneal metastasis (++), sheep fat, anterior chamber flash (++), aqueous humor cells (++), The pupil is not round, plum-like, the posterior iris of the pupil is stuck, the vitreous is turbid (++), the border of the optic disc is unclear, the color is red, the retina is changing in the evening, the retinal vein is slightly filled, the pigmentation in the macular area is disordered, and the center is reflective. .
