What symptom does iritis have

summary

Iridocyclitis is also known as anterior cephalocephalitis. Iridocyclitis affects the ciliary body after iridocyclitis occurs. Therefore, it is rare to have iridocyclitis or ciliary body inflammation alone in clinic, and usually occurs at the same time. There are many causes of iridocyclitis. In addition to the direct entry of bacteria, viruses, chemicals, etc. into the eyes due to ocular trauma, systemic diseases such as tuberculosis, leprosy, rheumatism, leptospirosis, etc. are the important causes of iridocyclitis. Other language tissues adjacent to iris and ciliary body, such as keratitis and scleritis, can also cause the disease.

What symptom does iritis have

First: its clinical manifestations, first of all, pain, photophobia, tears and vision loss are the main characteristics of the disease. The trigeminal nerve endings of iris and ciliary body are subject to toxic stimulation, contraction and swelling of ciliary muscle, and compression of tissue. The pain can be reflected to the artist and cheek. There is obvious tenderness in ciliary body, and the pain is aggravated at night. In acute stage, it is often accompanied by keratitis reaction, such as shyness, tears, and sudden decline of vision.

Second: check out, there is obvious ciliary congestion, serious cases, can also form mixed congestion and conjunctival edema. Corneal deposition is to prevent edema, inflammatory cells and pigment. Due to the temperature difference on the iris surface behind the cornea, with the influence of centrifugal force and gravity of anterior chamber water convection, it adheres to the corneal endothelium and corneal deposition after inflammation. The deposition is mostly in the center of the cornea, with triangular distribution at the lower part, tip toward the pupil area, large particles at the lower part and small particles at the upper part.

Third: due to the increase of protein content in aqueous humor caused by inflammation, aqueous humor becomes mixed. Under slit lamp, aqueous humor is light gray with reflective reflective band, which is called Tyndall sign. It is a sign of active inflammation. In severe cases, cellulosic and purulent exudates may appear. Due to gravity, they are deposited in the lower part of anterior chamber, showing a fluid screen area of anterior chamber empyema. If the blood vessel ruptures, no extracellular fluid is produced Hyphema.

matters needing attention

In the early stage of iris inflammation, due to iris congestion, edema, cell infiltration and exudate toxin stimulating the contraction of sphincter and dilator at the same time, the pupil shrinks and is insensitive to light. The ciliary body is adjacent to the vitreous body. The fine dust and flocculent exudate of iridocyclitis can invade the anterior part of the vitreous body after the lens and make it turbid.
