Uveitis is a group of inflammatory diseases affecting the uveal tract, retina, retinal blood vessels and vitreous. Due to its complex etiology, various entities, diverse and lack of constancy in treatment, some patients can experience visual impairment and even loss. In view of the fact that blindness caused by uveitis is mostly incurable and occurs usually in young and middle-aged people, it accounts for an important part of blinding eye diseases and has attracted worldwide attention. With the continuous development of precision medicine, clinicians will face new problems and challenges in disease diagnosis, and further in-depth research is needed to explore more optimized and efficient diagnostic processes and examinations to improve the diagnosis of uveitis in China.
PURPOSE:To investigate and changes of the retina and the chorid induced by lipopolysaccharide (LPS)in Lewis rats and to compare the results obtained on tissue wholemounts and sections. METHODS:Immunohistochemistry was carried out both on wholemounts of the retina and the chorid-sclera complex and on ocular sections from normal Lewis rats and those after LPS injection. RESULTS:It was shown on the tissue wholemounts that monocytes were attached to retinal blood vessels and emigrated into the choroid as early as 4hrs after LPS injection. Severe involvement of the retina and macrophages into whole area of these tissues.Furthermore increasing number of major histocompatibility complex classⅡ(MHC classⅡ)positive cells was observed in the choroid.The results on tissue sections revealed that the retina and the choroid were both involved as videnced by infiltration of these cells at some time points after LPS injection. CONCLUSION:Wholemount technique provides undoubtful evidences to show that the retina and choroid are primarily and severely involuted after LPS injection.The endotoxin induced uveitis is,for the first time,presumed to be model for human generalized uveitis. （Chin J Ocul Fundus Dis,1996,12:33-36）
Clinical materials of 198 patients with anterior uveitis were amdysed. The etiologic factors of disease, were estimated by history of the disease,clinical manifestation,concurrent diseases and laboratory findings.The main relevant causes were found successively to be rheumatlc arthritis (57 cases,28.79%), Fuchs syndrome (15 cases,7.58%) and herpes simplex virus infection (10 cases,5.05%).The diagnosis,treatement and etiology of anterior uveitis were discussed,and it was suggested that early diagnosis and appropriate treatment are key to prevent loss of sight. （Chin J Ocul Fundus Dis,1994,10:159-161）
Clinical features and diagnosis of Behcet's disease were presented based on Z8 Chinese patients. It was found thtt uveitis,recurrent oral aphthae,multiform skin lesions and genital ulcer occurred in 100%,96.43%,96.43%and 53.57% respectively of the patients.The Uveitis with recurrent feature,frequently accompanied by retinal vasculitis,was at great risk of developing blindness.It was pointed that the knowledge about the features of both ocular and extraocular manifestations was the key to making a correct diagnosis. （Chin J Ocul Fundus Dis,1994,10:133-137）
Behccedil;et's disease,a stubborn malady,has extremely bad visual prognosis due to the recurrence of uveitis. The combination of chlorambucil with traditional Chinese medicine herbs was designed to treat 16 patients with Behccedil;ets disease,resulting in total remission of uveitis in 11 patients and partial remission in 5 patients. Visual improvement was seen in 63.33% of the eye involved in Bebcet's disease. The extraoeular manifestations such as oral aphthae,multiform skin lesions,genital ulcer and muscular pain were disappeared in 10 patients and dramatically improved in 6 patients. The treatment was well tolerated by the patients with few side effects. The indications,side etfeets and relevant problems of the treatment were discussed based on the results presented here. （Chin J Ocul Fundus Dis,1994,10:142-148）
Eighteen male patients and 10 female patients with Bt.Behccedil;et's disease were addressed to study the influences of sex factor on Behccedil;et's disease. It was found that recurrences of uveitis were more frequent in malepatients than in females,and that male patients were worse than females in prognosis due to the high severity of retinal vasculitis and the low sensitivity to treatment.It is pressumed that the sex hormone may, at least in part,contribute to the diffrenees between the male and female patients. （Chin J Ocul Fundus Dis,1994,10:143-145）
