Clinical features of ankylosing spondylitis associated with acute anterior uveitis in Chinese patients

AIM: To characterize the clinical features, diagnosis, treatment and prognosis of uveitis associated with ankylosing spondylitis (AS) in Chinese patients. METHODS: Two hundred and three patients with uveitis associated with AS followed-up in the Third Military Medical University Daping Hospital between 2005 and 2010 were retrospectively evaluated in this study. Complete ophthalmological examinations were evaluated at baseline and during the follow-up period. The gender, age, follow-up time, mean frequency of uveitis onset, and accompanying eye examination findings, history, demographical parameters were reviewed. All the patients presented complete clinical and radiologic (sacroiliac, lumbar, dorsal and cervical spine, knee, ankle, shoulder, hip, elbow) evaluation. HLA-B27 typing was also searched. RESULTS: There were 203 patients diagnosed with AS associated welt's. All showed sacroiliac X-ray changes indicative of AS. There were 184 male and 19 female patients. The average age of patients was 35 +/- 12 (range 18-50). Mean follow-up period was 2.4 years (1-5 years). Acute anterior wets was the most common type of uveitis in both genders. 121 eyes presented unilateral involvement (55.2%), and 92 eyes presented bilateral involvement (45.3%) with onset alternately. 22 eyes occurred hypopyon, 16 eyes were found anterior vitreous cells, 7 eyes were noted reactive macular edema or exudation, 29 eyes presented posterior synechiae of iris, and 14 eyes presented cataract, 9 eyes presented secondary glaucoma, 2 eyes presented bend corneal degeneration and 1 eyes presented atrophy of eyeball. At the final visit, uveitis was well controlled in most patients. CONCLUSION: AS associated with uveitis in Chinese patients mainly manifests as acute anterior uveitis. A combination of corticosteroids with other mydriasis agents is effective for most AS associated with uveitis patients. In general, the prognosis is good in these cases.

Ten Years of Epidemiological and Diagnostic Aspects of Non-Traumatic Anterior Uveitis at Campus Teaching Hospital of Lome-Togo

Background: Uveitis is a serious disease which dangerous complications can jeopardize the visual prognosis. Anterior uveitis (AU) is the inflammation of the anterior uvea which is composed of the iris and the ciliary body. The objective of the study was to identify the epidemiological and etiological determinants of non-traumatic anterior uveitis at the Campus Teaching Hospital of Lomé. Materials and methods: Retrospective cross-sectional study of the records of patients diagnosed with anterior uveitis (AU) without a notion of trauma in the ophthalmology department of CHU Campus of Lomé from January 1, 2010 to December 31, 2019 (10 years). Results: 141 cases of uveitis, representing a prevalence of 0.18%. Female predominance, with a sex ratio of 0.76. Mean age was 34.74 ± 13.20 years. Decreased visual acuity was the primary complaint (34.40%), followed by ocular pain (28%). Non-traumatic anterior uveitis was unilateral in 87.2% of cases. Retro-corneal precipitates were present in all patients. 61.60% of patients had Tyndall in the anterior chamber. The etiology of non-traumatic AU was undetermined in 76.80% of cases. Toxoplasmosis, tuberculosis and syphilis were the main etiologies found. Conclusion: Non-traumatic anterior uveitis is relatively rare but serious, often affecting young subjects. It is a pathology that engages eye health professionals, not only because of the difficulties involved in diagnosing the etiology, but also because of its progression which sometimes leads to blindness.

Inhibitory Effects of Tetandrine on Experimental Anterior Uveitis Rabbits

Anterior uveitis was induced by injection of lens protein into anterior chamber of rabbit eye.Tetrandrine (Tet) (50mg/kg ip) showed marked inhibition on this ocular inflammation, the total content of prostaglandin E in irises, and leukocyte chemotaxis.The pathological examination revealed that inflammation of irises in Tet group was lighter than that in control group. The antiinflammatory mechanism of Tet may be related to reduction of intracellular free calcium and inhibition of synthesis of inflmmatory factor.

Clinical Analysis of 240 Patients with HLA-B27 Associated Acute Anterior Uveitis

Purpose: To analyze the prevalence of HLA-B27 associated acute anterior uveitis and to identify its clinical features. Methods: A total of 240 patients with HLA-B27 associated acute anterior uveitis,who were admitted to Zhejiang Ophthalmologic Hospital between December 2006 and October 2012, were retrospectively analyzed.The age of onset,sex,affected eyes,HLA-B27 antigen detection,recurrence,joint involvement, and surgical complications were investigated. Results:The average age of onset was 37.0 ±12.0 years and the ratio of male to female patients was 2.4:1. Most cases had alternate unilateral or bilateral involvement. Among all participants, 234 cases (97.5%) were HLA-B27 positive, and 124 cases (51.7%) had spondyloarthropathies (SpA), dominated by 108 cases with ankylosing spondylitis. (AS,45.0%),and mostly seen in male subjects(P<0.05).Six patients were HLA-B27 negative(2.5%)and on statistical significance was noted between male and female patients (P >0.05).A total of 193 cases (80.4%) presented with complications, mainly fibrinous exudation, posterior synechia, and vitreous opacity. Conclusion: HLA-B27 that is associated acute anterior uveitis with a relatively high incidence and recurrence presents with more severe clinical features than does idiopathic acute anterior uveitis,and it often accompanies systemic arthritic diseases. HLA-B27 antibody detection is associated with the diagnosis and treatment of acute anterior uveitis.

Presumed Acquired Retinal Astrocytoma in Association with Anterior Uveitis

Purpose:To report a case of presumed acquired retinal astrocytoma in association with anterior uveitis. Methods:A 29-year-old man presented with mutton fat keratic precipitates in the inferiorlower cornea,with complicated cataract and a circumscribed,solitary,yellowish-white retinal lesion in the right eye.Phacoemulsification with intraocular lens implantation was performed, with election to observeand the lesion was observed periodically. The lesion was followed for over two years without any change in size, shape or, and appearance. The anterior uveitis has not recurred at the time of writing. Results:Systemic medical and laboratory evaluations, including chest computed tomography,cranial magnetic resonance imaging,and serum angiotensin converting enzyme level, were normal. The characteristic fundus, FA,OCT scan, ultrasound scan,and lack of other contributory laboratory findings strongly supported the diagnosis of acquired retinal astrocytoma in this patient. Conclusion:We hypothesized that anterior uveitis may contribute to the growth and maintenance of retinal lesions. (Eye Science 2013; 28:51-54)

幽门螺杆菌与眼部疾病相关性研究进展

幽门螺杆菌是一种常见的革兰氏阴性细菌,与多种消化系统疾病有关,如胃炎、十二指肠溃疡和胃癌等。近年来的研究显示幽门螺杆菌也和一些常见的眼科疾病有关,如中心性浆液性脉络膜视网膜病变、青光眼、前葡萄膜炎、眼附属器淋巴瘤等。幽门螺杆菌可能通过氧化损伤、循环障碍和免疫损伤等方式影响眼部疾病的病理生理过程。也有一些研究提示根除幽门螺杆菌对某些眼病有一定效果。本文对幽门螺杆菌在常见眼部疾病发生发展中的机制进行综述,深入探讨幽门螺杆菌与常见眼部疾病的关系可为有些眼病的预防或治疗提供新的思路。

Fuchs葡萄膜炎综合征临床特点及误诊原因分析

目的探讨Fuchs葡萄膜炎综合征(FUS)的临床特点及误诊原因、防范措施。方法回顾性分析曾误诊为其他疾病的FUS 9例的临床资料。结果本组7例视力下降,其中2例伴眼胀,1例伴眼前黑影飘动;2例自觉无症状。9例最佳矫正视力4.4~5.0;皆出现虹膜脱色素和前房闪辉阳性,星状角膜后沉着物8例,瞳孔欠圆7例,晶状体密度增高6例。就诊初期外院误诊为前葡萄膜炎3例,年龄相关性白内障2例,原发性开角型青光眼合并年龄相关性白内障、前葡萄膜炎并发白内障、青光眼睫状体炎综合征和全葡萄膜炎各1例。误诊时间3 d~5年。入院后经详细病史询问结合临床资料及相关检查,确诊为FUS,给予相应治疗视力恢复良好、病情稳定。结论FUS易误诊,临床医师应加强对其认识和认真鉴别诊断,以减少或避免误诊误治。

青光眼睫状体炎综合征的研究进展

青光眼睫状体炎综合征(PSS)是一种较少见、反复发作的自限性前葡萄膜炎,目前发病机制仍不明确,曾认为是前列腺素介导的炎症反应,近年发现与病毒感染、免疫遗传、血管内皮功能障碍等因素相关。临床上多单眼发病,发作时眼压升高,患眼轻度疼痛、视物不清、虹视等,较少引起视神经及视野损害。治疗以局部抗炎、降眼压为主,严重者可全身用药。如果PSS眼压升高药物不可控、发作频繁、病程长造成视神经损害、视野缺损,可进行手术治疗。对PSS早诊断、早治疗可以减少青光眼相关损害。本文将从多个方面论述PSS的研究现状,期望对本病的病因、发病机制及临床诊治方面提供参考。
