uveitis associated with diabetes
Introduction
Introduction to uveitis associated with diabetes Diabetes is a common disease. There are four general conditions for uveitis associated with diabetes: 1 uveitis associated with diabetes itself, mainly anterior uveitis; 2 infectious uveitis (eye) Endocrine); 3 with some specific types of uveitis; 4 infective endophthalmitis or aseptic endophthalmitis after intraocular surgery. basic knowledge The proportion of illness: 0.001% Susceptible people: no specific population Mode of infection: non-infectious Complications: iris neovascularization cataract glaucoma
Cause
Causes of uveitis associated with diabetes
(1) Causes of the disease
diabetes.
(two) pathogenesis
The pathogenesis of diabetes associated with uveitis is still unclear. Some people think that the so-called inflammatory reaction in diabetes may be caused by ischemia, not true uveitis, but it is clinically found that the uvea associated with diabetes Recurrent episodes of inflammation, a good response to glucocorticoid eye drops, which suggests that it is indeed an inflammatory disease, limited HLA antigen typing research is not certain that the two have a common genetic background, diabetes patients Bacterial infections are prone to occur due to reduced resistance to various infections.
Prevention
Uveitis prevention associated with diabetes
Actively control the condition of diabetes.
Complication
Uveitis complications associated with diabetes Complications, iris neovascularization, cataract, glaucoma
There may be complications such as post-iris adhesion, iris neovascularization, complicated cataract, secondary glaucoma.
Symptom
Symptoms of uveitis associated with diabetes common symptoms photophobia, ciliary congestion, urinary eye pain, tearing sepsis
Uveitis associated with diabetes can be expressed as a special hair style, or can be expressed in certain specific types, such as Vogt-Koyanagi Harada disease, Behcet disease, etc., but the diabetes is associated with these specific uveitis types. The intrinsic link is still unclear. In uveitis associated with diabetes, the onset of uveitis often occurs after diabetes.
The initial onset is mostly acute anterior uveitis, sudden onset, eye pain, photophobia and tearing, examination showed ciliary congestion, a large number of fine dusty KP, anterior chamber flash (+ ~ ++), anterior chamber inflammatory cells (++~++++), a small number of patients have a large amount of fibrinous exudation in the anterior chamber, and even anterior chamber empyema. This acute inflammatory reaction can quickly resolve after appropriate treatment, but most patients have recurrent episodes, showing acute Recurrent anterior uveitis or chronic recurrent anterior uveitis, some patients eventually develop post-iris adhesions, iris neovascularization, complicated cataract, secondary glaucoma and other complications and sequelae, but some patients appear as Chronic anterior uveitis, no obvious ciliary congestion, only mild iritis or iridocyclitis, diabetes can also cause or associated with posterior uveitis, intermediate uveitis and total uveitis.
Diabetic patients are prone to sepsis metastatic lesions. Cheng et al analyzed 23 patients and found 14 cases (60.8%) with uveitis or endophthalmitis.
Diabetic patients are prone to cataract, diabetic retinopathy and iris reddenosis. The cataract extraction combined with intraocular lens implantation should be particularly careful because of the possibility of fibrinous exudation, increased redness and neovascularization of the iris. Glaucoma, Hykin et al performed cataract extraction and intraocular lens implantation in 13 eyes with iris reddenation. It was found that in 8 eyes without proliferative retinopathy, fibrinous exudation occurred in 5 eyes. Uveitis in patients with diabetic proliferative vitreoretinopathy is more severe, but inflammation in most patients can be controlled by local glucocorticoid eye drops, and iris reddening and proliferative diabetic retinopathy are also found. The patient's visual prognosis is poor. In order to improve the postoperative results, total retinal photocoagulation should be performed as much as possible before surgery.
Examine
Examination of uveitis associated with diabetes
Conduct some laboratory tests for diabetes to monitor the treatment outcomes of diabetes and its outcomes.
A fissure examination can determine the extent of anterior segment lesions, including changes in the uvea and lens.
Diagnosis
Diagnostic diagnosis of uveitis associated with diabetes
According to slit lamp microscopy, the diagnosis of uveitis is not difficult, but it is worth noting that when patients with uveitis are encountered, they should be asked whether they have a systemic history such as diabetes, and some mild diabetic patients present with uveitis. I don't know if I have diabetes. It is very beneficial to treat patients with diabetes early. It is worth noting that the uveitis associated with diabetes occurs mostly in middle-aged and elderly people, so it occurs in middle-aged or elderly people. Uveitis, especially acute anterior uveitis, should be considered the possibility of uveitis caused by diabetes, and related aspects of the examination to determine or exclude this type of uveitis.
The differentiation from common pre-cash is that the disease is closely related to diabetes.
