囊袋阻滞综合征(capsular block syndrome，CBS)是白内障手术较为罕见的并发症，可发生在白内障术中、术后早期及晚期。本文报道1例23岁的女性患者，为发生在白内障术后早期的CBS，因左眼激素性白内障而实施左眼白内障超声乳化联合后房型人工晶状体(intraocular lens，IOL)植入术，术后患者因屈光不正、后囊膜及IOL之间较宽间隙而诊断为CBS，行Nd:YAG激光后囊膜切开治疗后，患者视力恢复至正常，后囊膜及IOL贴合紧密，随访期间未出现黄斑水肿及视网膜脱离等并发症。

Capsular block syndrome (CBS), a fairly rare complication of phacoemulsification, can develop into one of the three following possible clinical scenarios: intraoperative, early postoperative, and late postoperative, depending primarily on the timing of its occurrence following surgery. This paper reported a patient who developed early capsular block syndrome. A 23-year-old patient complained of poor distant vision after undergoing phacoemulsification combined with intraocular lens (IOL) implantation because of steroid-induced cataract. Anterior segment examination confirmed the diagnosis of capsular block syndrome. Neodymium-doped yttrium aluminum garnet (Nd:YAG) laser posterior capsulotomy resulted in complete resolution of her symptoms. No complication happened during follow-up.

目的：调查干眼在郑州市机关工作者中的患病情况，分析相关危险因素，为有效防治干眼提供科学依据。方法：选取2019年9月到2020年9月在郑州大学第一附属医院体检的郑州市机关工作者873例。采用自行设计的一般资料问卷和OCULUS Jenvis-OSDI干眼问卷进行调查，记录评分结果，同时检查记录裂隙灯、角膜荧光素染色评分(corneal fluorescein staining score，FL)、基础泪液分泌实验(Schimier I test，SIT)、泪膜破裂时间(tear break-up time，BUT)测定结果。统计分析机关工作者干眼患病率与危险因素。结果：体检的873例郑州市机关工作者中360例诊断为干眼，干眼总患病率为41.24%，女性患病率(44.62%)明显高于男性(36.26%)，差异有统计学意义(P=0.014)。干眼问卷OSDI评分与FL评分呈正相关，BUT与SIT呈正相关，OSDI(和FL评分)与BUT(和SIT)呈负相关。Logistics多因素分析表明：干眼家族史、绝经、曾行眼部手术、滴眼液使用情况、长时间佩戴角膜接触镜、长时间操作视频终端、睡眠不足、糖尿病史是机关工作者干眼患病的危险因素(均P<0.05)，而饮酒是保护因素(P=0.001)。结论：机关工作者干眼患病率较高，危险因素囊括家族患干眼史、绝经、曾行眼部手术、滴眼液使用情况、长时间佩戴角膜接触镜、长时间操作视频终端、睡眠不足、糖尿病病史。加强干眼防治的宣传教育，针对不同危险因素提供眼健康指导并进行防控治疗，保护机关工作者的眼健康。

Objective: To investigate and analyze the prevalence of dry eyes in Zhengzhou office workers, and identify the related risk factors in order to provide evidence for effective prevention and treatment. Methods: We selected 873 cases of Zhengzhou office workers who had checkup in our hospital from September 2019 to September 2020 as the research subjects. They were investigated with self-designed general information questionnaire and OCULUS Jenvis-OSDI dry eye questionnaire and scores of the questionnaires will be assessed. At the same time,they underwent dry-eye-related inspections such as slit lamp examination, corneal fluorescein staining score (FL), Schimier I test (SIT) and tear break-up time (BUT) assessment. The prevalence and risk factors of dry eyes in these office workers were statistically analyzed. Results: Among 873 Zhengzhou office workers, 360 cases were diagnosed as dry eyes, and the total prevalence of dry eye was 41.24%. The female prevalence rate was 44.62%, which was significantly higher than that of male (36.26%, P=0.014). OSDI scores and FL scores were positively correlation as well as BUT and SIT, while OSDI (and FL) and BUT (and SIT) were negatively correlation. Logistic multivariate analysis showed that dry eyes family history, menopause, ocular surgery history, eye drops using, long time corneal contact lenses wearing, long time video terminal operating, lack of sleep and diabetes history were independent risk factors in office workers’ dry eye disease (all P<0.05), while drinking was protective factor (P=0.001). Conclusion: The dry eyes prevalence is high among office workers. The risk factors include dry eye family history, menopause, ocular surgery history, eye drops using, long time corneal contact lenses wearing, long time video terminal operating, lack of sleep and diabetes history. We should strengthen the publicity and education of the dry eye prevention and treatment, provide eye health guidance, prevention and treatment according to different risk factors, and protect the office workers’ eye health.
