[ad_1]

Most eye diseases that cause blindness are often associated with aging, but there are diseases that can result in blindness even in young, healthy patients. What is uveitis that can cause a sudden onset and cause severe symptoms?

What is uveitis?

Lee, who is in normal health without special medical problems and has never been to a hospital, suffers from decreased visual acuity after the onset of redness and pain in the right eye. I felt tired at first, but the symptoms became very serious. At the time of admission, my vision reached the level of safety (I could not see the vision plate and could count the number of fingers before 30cm). ophthalmology and blood tests The cause of uveitis is related to ankylosing spondylitis.

Uveitis is an inflammation that occurs literally in the uvea. The uvea is an iris that forms the middle layer of the eyeball (brown tissue in the front of the eye), a ciliary body and a choroid, rich in blood vessels and prone to inflammation, and the inflammation that occurs here is called uveitis. Uveitis is divided into anterior uveitis, middle uveitis and uveitis, depending on its location, and all forms of uveitis are called total uveitis. Several causes, such as germs, viruses, parasites, traumas and systemic inflammatory diseases are known, but idiopathic uveitis can occur without any specific cause.

Symptoms and Diagnosis of Uveitis

Uveitis may have several symptoms depending on its location and degree of inflammation. The anterior uveitis is usually acute, congestion, pain and intense light can cause symptoms like eye tearing, and eye inflammation can be caused by severe inflammation. In the middle of uveitis and uveitis, the main symptoms are decreased vision and insomnia. In cases of uveitis, glow and varicose veins may appear.

Symptoms caused by uveitis may also occur in other inflammatory diseases, such as conjunctivitis, keratitis, or scleritis. Therefore, you should consult your ophthalmologist to make an accurate diagnosis. For diagnosis, it is necessary to confirm inflammation in the anterior part of the anterior eye through slit-lamp microscopy, and the intraocular pressure test is necessary because it may be accompanied by hypotonia or ocular hypertension. In some cases, examination of the fundus of the eye is performed to confirm inflammation in the fundus of the eye, and fluorescein angiography or optical coherence tomography is performed to discriminate more accurately among other eye diseases and retinal complications.

In addition to ophthalmologic examinations for diagnosis, it is necessary to identify systemic diseases accompanied by uveitis, requiring blood tests, including genetic tests and radiological examinations. If the patient has systemic inflammatory disease or autoimmune disease, treatment should be done only if the internal medicine is co-operated and managed, so it is important to examine this systemic disease. Despite a variety of tests, there are cases where no apparent cause can be found.

Complications due to uveitis

Chronic recurrent uveitis itself may also reduce visual acuity, and secondary visual loss may also occur if the optic nerve is involved or if the macular papules develop. Other complications of uveitis include iris adhesion, iris atrophy, cataract, glaucoma, retinal detachment, retinal detachment, retinal atrophy, uvetic atrophy, optic atrophy, guidewire angiogenesis, vitreous hemorrhage, loss and eyeball conditions may occur. The eyeball is a condition in which the general function of the eye is so poor that it causes black opacity, decreased intraocular pressure, decreased eye size and loss of vision.

In the treatment of uveitis, various drugs, such as steroids, are used, in the case of drug treatment for a long time, various problems like cataract, glaucoma, ptosis, gastric ulcer, diabetes and hypertension can occur due to drug, It is necessary.

Treatment of uveitis

If a cause is found, appropriate treatment for the cause of the disease is performed. In case of infectious causes, antibiotics and antivirals suitable for causative bacteria or virus causing infections will be used. If it is not infectious, topical medicines for the control of inflammation, such as eye drops or oral medications (steroids) are necessary. Pain relief and irritation of the eyes (a paralyzing agent) that shakes the pupil to prevent adhesion of the posterior iris to the surrounding tissue are treated with eye drops. If necessary, ocular or intraocular injections of steroids may be performed in addition to oral / oral steroids. Inflammation does not subside or recur, and in the case of recurrent chronic inflammation, immunosuppressants are sometimes necessary, and in this case, a blood test is usually required for possible adverse drug reactions. It is associated with inflammation and can cause various intraocular complications, such as macular edema, exudative retinal detachment, and glaucoma. In addition, such complications can cause side effects, even if the inflammation decreases, and the visual disturbances caused by such complications can be left behind, so continuous observation and appropriate treatment are important. Therefore, it is recommended to visit the ophthalmologic clinic without delay, if the same symptoms are repeated after treatment, to minimize ocular damage by diagnosis and treatment, and to receive regular ophthalmologic examination without recurrence.

Although uveitis is a serious ophthalmological disease, which can cause blindness and blindness, it is still a popular awareness of the disease, I think it is usually & # 39; tired & # 39; and & # 39; temporarily. Experience. It is important to keep an eye on health care to avoid the unfortunate situation when you miss the appropriate period of treatment and after the disease has progressed considerably.
