Peripheral uveitis
Introduction
Introduction to peripheral uveitis Peripheral uvitis (peripheraluveitis), also known as parsplanitis, is a granulomatous uveitis that is common in healthy people and is a chronic process of multiple eye diseases. basic knowledge The proportion of illness: 0.0035% Susceptible people: no specific population Mode of infection: non-infectious Complications: cataract edema optic atrophy
Cause
Peripheral uveitis
The cause is unknown and may be related to immune factors. The cause can be divided into two major categories, infectious and non-infective. The former includes infections caused by bacteria, fungi, spirochetes, viruses, parasites, etc. The latter includes idiopathic, autoimmune, rheumatic diseases, and trauma. Sex, camouflage syndrome, etc. The etiology and pathogenesis of uveitis is mainly due to the invasion of external evils or internal heat; it is related to the dysfunction of liver, kidney and spleen.
Prevention
Peripheral uveitis prevention
There are black shadows in front of you. If the symptoms are mild, it is generally known as "floating mosquitoes". It is not necessary to treat them. However, some people have found that children and adolescents have black eyes in front of them, but some of them are caused by peripheral uveitis. If it develops, there is a danger of blindness. Therefore, if the young children complain that there is a black shadow floating in front of the eyes, they should come to the hospital as soon as possible to see if they have peripheral uveitis in order to get timely treatment. This disease is a chronic disease. Treatment must be adhered to, but during the application of corticosteroids, care should be taken to avoid systemic and ocular complications.
Complication
Peripheral uveitis complications Complications cataract edema optic atrophy
Later lens opacity and cataract occur in the posterior lens. In some cases, macular edema may occur, leaving pigmentation disorder, and some secondary optic atrophy and loss of vision.
Symptom
Peripheral uveal inflammation symptoms common symptoms papilledema edema eye pain ciliary congestion bloody unilateral fundus...
According to clinical findings, the following three types can be divided:
1, benign type: the prognosis is good, the exudation disappears after a few months of onset, leaving retinal atrophy and pre-irisal adhesions around the iris.
2, vascular occlusion type: began to have exudate at the near serrated edge, vascular occlusion around the retina, white sheath, lesions gradually develop backwards leading to optic atrophy.
3, severe type: the periphery of the fundus has a large amount of flocculation exudation, the formation of ciliary membrane, vitreous body with new blood vessels, mechanical membrane traction can produce bleeding or the formation of a hole to eventually produce retinal detachment.
First, the symptoms
In the early days, there were dark shadows, blurred vision, and severe visual acuity and peripheral visual impairment, and occasional eye pain.
Second, physical signs
1, ciliary congestion, generally no ciliary congestion, or mild congestion.
2, the cornea is transparent or has a small round white KP of sheep fat, visible anterior chamber flash or floating inflammatory cells, grayish yellow exudate in the corner.
3, the iris is rarely stuck before and after.
4, fundus conditions: in the case of adequate dilation, it can be found that the anterior vitreous and basal part of the angstrom or small granule opaque spherical opacity is located in the lower part of the eyeball, the lesion mostly occurs in the flat part of the ciliary body and the choroid, fusion It has a yellow-white cotton ball-like appearance, a flat-toothed serrated edge, a gray sphere or a large piece of exudation in front of the retina, which merges into a ciliary shape, covering the cleft tooth edge and forming a bank shape. It is called a snow bank exudate. ), the mechanism from the flat part of the ciliary body is directly inserted into the vitreous body, and surrounds the crystal to form a cyclitis membrana, which may also have macular edema, papilledema, peripheral retinal vasculitis, white blood vessels in the blood vessels and Occlusion, but can be found to identify the cause of the disease, that is, peripheral uveitis.
Examine
Peripheral uveitis examination
1. For the diagnosis of general choroiditis, the main frame A is checked.
2. For those who have complications or to find possible causes, the check box may include "A", "B" and "C".
Diagnosis
Diagnosis and diagnosis of peripheral uveitis
diagnosis
Diagnosis can be based on medical history, clinical symptoms, and laboratory tests.
Differential diagnosis
The clinical manifestations of anterior uveitis are: pain, photophobia, tearing and vision loss are the main features of the disease. Main signs: ciliary congestion, corneal depression, aqueous humor, iris texture, pupil dilation, vitreous opacity.
The main symptoms of posterior uveitis are: vision loss and flashing of the eyes and shadows, sometimes with small eyes and big eyes. There is vitreous opacity, increased choroidal vasodilatation permeability, tissue infiltration edema, and diffuse grayish white lesions in the fundus.
