Introduction Ocular tuberculosis (TB) is an extrapulmonary manifestation of mycobacterium infection that most commonly presents as uveitis. This is the first prospective incidence study of presumed ocular tuberculosis performed in the United Kingdom (UK). Method New cases of ocular tuberculosis presenting to hospitals in the UK were prospectively ascertained between October 2016 and November 2017 with the aid of the British Ophthalmological Surveillance Unit (BOSU). Initial presentation data and 1-year follow-up data was collected using questionnaires. Results Forty-eight patients were recruited giving an overall incidence for ocular TB of 0.73 per million population per annum. The origin of birth for 71% of the patients was a non-UK country and 87.5% had their initial diagnosis of TB made by an ophthalmologist. The most common first line treatment was isoniazid, rifampicin, ethambutol and pyrazinamide which 71% of patients were treated with 60% of patients were commenced on a reducing course of oral steroids. At 1-year follow-up, 29 patients (83%) had complete resolution of active clinical signs. Mean best corrected visual acuity (BCVA) at presentation was +0.41 LogMAR(SD = 0.62), compared to +0.31 LogMAR (SD = 0.56) at 12-month follow-up. Discussion It is increasingly the responsibility of the ophthalmologist to diagnose ocular TB and although it remains a rare condition, consensus on diagnostic criteria and treatment is required. Increasing recognition and accessibility to gamma-interferon testing should enable earlier detection. Treatment with quadruple ATT treatment regimens for at least 6 months shows good clinical outcomes. However, it is still unclear whether steroid use is beneficial. Further large studies with longer follow-up would be warranted to answer these questions.

英国疑似眼结核:英国眼科监测单位 (BOSU) 的一项研究

简介 眼结核 (TB) 是分枝杆菌感染的肺外表现,最常表现为葡萄膜炎。这是在英国 (UK) 进行的第一个假定的眼结核的前瞻性研究。方法 在英国眼科监测单位 (BOSU) 的帮助下,在 2016 年 10 月至 2017 年 11 月期间,前瞻性地确定了在英国医院就诊的新眼结核病例。使用问卷收集初始报告数据和 1 年随访数据。结果招募了 48 名患者,眼部 TB 的总发病率为每年每百万人口 0.73。71% 患者的出生地是非英国国家,87.5% 的患者最初诊断为 TB,由眼科医生做出。最常见的一线治疗是异烟肼、利福平、乙胺丁醇和吡嗪酰胺,其中 71% 的患者接受了治疗,60% 的患者开始口服类固醇减量疗程。在 1 年的随访中,29 名患者 (83%) 的活动性临床症状完全消失。就诊时的平均最佳矫正视力 (BCVA) 为 +0.41 LogMAR(SD = 0.62),而在 12 个月的随访中为 +0.31 LogMAR (SD = 0.56)。讨论 眼科医生越来越有责任诊断眼部结核病,尽管它仍然是一种罕见的疾病,但需要就诊断标准和治疗达成共识。提高对伽马干扰素测试的识别度和可及性应该能够实现早期检测。用四联 ATT 治疗方案治疗至少 6 个月显示出良好的临床结果。然而,目前尚不清楚使用类固醇是否有益。需要进行更长时间随访的进一步大型研究来回答这些问题。
