Iritis

Introduction to iritis Inflammation of the iris is called iritis (the iris is the part that determines the color of the eye). Irne is not a rare disease. It can develop iriditis at any age, but the majority of patients are young. Iris can be divided into primary and secondary. If treated early, iritis is easy to cure. Many white cells accumulate in the aqueous humor, blocking the passage of aqueous humor out of the eye. At this point, it can trigger acute glaucoma. If the inflamed iris sticks to the front of the lens and traps the water behind the iris, it may also cause acute glaucoma. Long-term iritis can also cause cataracts. As long as there are signs of redness, discomfort or loss of vision for an unexplained eye, no matter how mild the symptoms are, you should see an ophthalmologist immediately. Even if it is the earliest treatment, iritis will still recur. However, in most cases, the iritis will completely subside, and the patient's vision will be somewhat damaged. basic knowledge The proportion of illness: 0.003% Susceptible people: no specific population Mode of infection: non-infectious Complications: cataract Glaucoma

Cause of iritis

Cause:

Herpes virus infection (20%):

If you have herpes zoster on your face, especially on the forehead or cheeks, it may cause iritis. Other infectious diseases, such as Toxoplasma infection, histoplasmosis, tuberculosis, syphilis, etc., may be associated with other types of iritis.

Genetic susceptibility (5%):

Those who carry the HLA-B27 gene have changed their specific genes that are closely related to human immune function, making them more susceptible to certain autoimmune diseases such as ankylosing spondylitis, Lytle syndrome, and inflammation. Enteropathy, psoriatic arthritis, etc. These diseases can be complicated by acute iritis.

Juvenile rheumatoid arthritis (15%):

Chronic iritis may occur in children with juvenile rheumatoid arthritis. For those with milder conditions and only a few joints involved, iritis may be one of the first signs to predict the disease. Because these two diseases are closely related, doctors often routinely screen for iritis or other types of uveitis in children with rheumatoid arthritis.

Eye trauma (25%):

Acute iritis can be caused by blunt trauma, penetrating wounds or burns (including chemical or thermal burns).

Posterior uveitis (20%):

It occurs in the inflammation of the back of the eyeball, which may spread to the front of the eye, causing iritis.

Pathogenesis:

The cause of acute iritis is, in particular, that the body is in a state of intense excitement for a long time, lacking sufficient rest and proper activities, resulting in an abnormal functional state of the body's immune system. The iris is located in the middle layer of the eye wall and belongs to the front part of the uveal membrane (also known as the pigmented membrane). It is rich in pigments and blood vessels, and the blood flow is slow. The allergic diseases of the immune system are easy to occur here. Acute iritis is related to the body's immune system dysfunction.

Iris inflammation prevention

Iris often involves the subsequent ciliary body causing iridocyclitis. The cause of iritis is unknown, and treatment must first be clearly identified. For signs of redness, discomfort or loss of vision for unknown reasons, no matter how mild the symptoms are, you should go to the hospital immediately. With iritis, the sooner you treat it, the easier it is to treat and the lower the likelihood of complications. Drug use also needs to be applied under the guidance of a doctor. Most people with iridocyclitis are associated with other autoimmune diseases, because it involves immune function, so it is difficult to prevent. Usually pay attention to work and rest, do not overwork, do not use excessive eyes, mood to be happy. Can use appropriate non-steroidal anti-inflammatory drugs such as Pu Nan Pu Ling, the effect is good. Hormone eye drops should not be used for long-term use (such as flumetine, dexamethasone ) can induce hormonal glaucoma .

Iris complication Complications cataract glaucoma

Corneal opacity

Posterior elastic layer wrinkles and corneal epithelial vesicular keratitis lesions, in the late stage of corneal banding.

2. Iris adhesion

In iritis, due to fibrinous exudation, adhesion between the pupil edge of the iris and the anterior capsule of the iris occurs. The early adhesion can be opened by the dilating agent. If the exudate has been mechanized, the adhesion is firm, and it is difficult to pull with the dilating agent. Open, or open a part of the adhesion pupil, the petal-like edge is not complete.

3. Pupil locking

After the iris is completely fibrotic, it can never be pulled open, and the iris of the pupil for one week is completely adhered to the front surface of the crystal, and the water circulation before and after is interrupted.

4. Front adhesion or corner adhesion of the iris

As the posterior atrial pressure increases or the exudate accumulates, the peripheral iris or iris root adheres to the posterior cornea.

5. Pupil membrane closure

A large amount of exudate is deposited in the pupil region to form a film covering the front surface of the crystal.

6. Iris bulging

Because the water can not flow forward from the back room, it is blocked in the back room, which increases the pressure in the back room. The accumulation of water causes the iris to move forward and expand.

7. Concurrent cataract

When the iris is inflamed, the nature of the aqueous humor changes, and the inflammation in the aqueous humor changes the external environment of the crystal, which also changes the normal physiological metabolism of the crystal, leading to turbidity of the cortex before and after the crystal, and the formation of complete cataract quickly.

8. Secondary glaucoma

Due to adhesion of the anterior chamber, pupillary atresia, vasodilation during acute inflammation, leakage of plasma, increased viscosity of the anterior chamber water, resulting in elevated intraocular pressure, secondary to glaucoma.

9. fundus lesions

Late stage or severe cases may be complicated by macular edema or cystic degeneration, or with optic disc vasculitis.

10. Eyeball atrophy

The exudative mechanized tissue near the ciliary body forms a fibrous membrane to pull the retinal detachment, destroying the ciliary body to reduce the secretion of aqueous humor, reducing the intraocular pressure, and the ciliary body itself repeatedly becomes inflamed and becomes necrotic tissue, causing the eyeball to shrink and shrink.

Iris symptoms common symptoms iris inflammation eyes red eyes stinging visual impairment

Pain, photophobia, tearing and vision loss are the main features of the disease.

The trigeminal nerve of the iris ciliary body is not slightly stimulated by toxicity. The contraction of the ciliary muscle and the pain caused by the compression of the swollen tissue can be reflected to the eyebrow and the cheek. The ciliary body has obvious tenderness, and the nighttime pain is exacerbated. Often accompanied by corneal inflammatory response and shame, tear vision can suddenly drop, due to intra-corneal edema, corneal depression and inflammatory exudation affect the entry of light, ciliary body is stimulated by inflammatory stimulation, causing false Myopia, advanced with macular edema and optic retinitis.

Iris inflammation check

Iris color change

1. Inflammation period: It appears in various parts of the iris and is golden yellow, indicating that there are symptoms of inflammation in the body.

2, the second inflammatory period: the area is brown.

3, chronic phase: dark brown, indicating that the tissue of the reflex zone has a function of decline.

4, degeneration period: dark black, indicating that most of the reflective tissue organs have lost function, it may also form tissue lesions, especially attention to the formation of tumors.

Diagnosis of iritis

The initial symptoms of iritis are redness of the eyes, discomfort or pain, and the accompanying symptoms are a slight loss of vision. If you look in the mirror, you can see the cells behind the cornea with the naked eye. The symptoms of iritis are usually not serious.

Iris is not a rare disease, it occurs at any age, but patients are most likely to be young.

The difference between iritis and pink eye

In the early stage of iritis, the symptoms of red eye disease (medical called acute conjunctivitis) are the same, and white eyeballs turn red. Therefore, the old experience is also considered to be red eye disease. It is good to take anti-inflammatory drugs for a few days. If it is not cured, it will be good on the seventh day. This practice is wrong. The reason for the error is that you do not understand the difference between the two diseases:

First, there are a lot of eyelids (eyelids) in red eye disease and there is no iritis.

Second, the red eye disease is lighter than the white eye mask around the black eyeball, and the iritis is particularly heavy here, like a red ring around the black eyeball.
