Inflammation of the iris
Introduction
Introduction Inflammation of the iris is called iritis (the iris is the part that determines the color of the eye), and sometimes the ciliary body behind the iris is also inflamed. When the iris is inflamed, the tiny white cells in the inflamed area and the excessive protein leaking from the small blood vessels in the eye float in the aqueous humor between the iris and the cornea. If there are too many cells floating in the aqueous humor, they will attack the back of the cornea and will precipitate in the aqueous humor. The cause of iritis is unknown. One eye or both eyes may be affected. 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.
Cause
Cause
The cause of iritis is unknown. One eye or both eyes may be affected.
Iris can be divided into primary and secondary.
Primary iritis is mostly due to iris damage and stimulation of intraocular parasites; secondary iritis is secondary to various infectious diseases (eg influenza, glandular epidemics, foot and mouth disease, snoring and cattle catarrhal fever), It may also be the result of the spread of inflammation in adjacent tissues. Suffering from eyesight, tearing, warming, and severe pain. The iris is swollen and deformed due to vasodilation and inflammatory exudation, the texture is unclear, and its inherent color and luster are lost. The anterior chamber of the eye is turbid due to the accumulation of exudate. Corneal nutrition is affected by turbid degeneration of the aqueous humor and dilatation of the anterior ciliary artery. Therefore, the cornea is slightly diffusely turbid. Because of the swelling of the pupil sphincter spasm and the iris, the pupil often shrinks and the response to the mydriatic drug is slow. Post-adhesion is easily formed due to dilated pupils and poor regulation.

The initial symptoms of iritis are redness of the eyes, discomfort or pain, and the accompanying symptoms are a slight loss of vision. The cells that accumulate behind the cornea can be seen with the naked eye, and the symptoms of iritis are usually not severe. 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 disease The initial symptoms of iritis are the same as those of pink eye disease (medical called acute conjunctivitis), and white eyes 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.
Diagnosis
Differential diagnosis
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 in red eye disease and there is no iritis.
Second, the red eye disease depends on the white eye mask red around the black eyeball, and the iritis is particularly heavy here, like a red ring around the black eyeball. Iris inflammation is one of the ophthalmologic emergencies. It develops rapidly, which can cause blindness and atresia after pupillary dislocation. It can not be delayed! Remember, red eyes and no eyelids are severe cases - iritis. Eyes are mostly mild and red eye disease. The initial symptoms of iritis are redness of the eyes, discomfort or pain, and the accompanying symptoms are a slight loss of vision. The cells that accumulate behind the cornea can be seen with the naked eye, and the symptoms of iritis are usually not severe. Iris is a rare disease that occurs at any age, but the majority of patients are young.
