Merkel细胞癌(Merkel cell carcinoma，MCC)是一种少见的高度恶性的皮肤原发性神经内分泌癌，发生于眼睑的MCC更加罕见。本文对2例眼睑MCC患者的临床病史和治疗过程进行回顾和总结。1例初发患者经手术彻底切除，效果良好，随访7年，未再复发；1例患者在外院切除术后2个月，于眼睑原位复发，再次行手术彻底切除，2个月后同侧腮腺淋巴结及颈前淋巴结扩散，目前仍在肿瘤科进一步放化疗中。复习相关文献并结合本组病例提示，MCC诊断主要依靠病理检查，彻底切除病灶并结合术后放化疗是其治疗的主要手段，免疫治疗是目前新的发展趋势。

The Merkel cell carcinoma (MCC) is a rare highly malignant primary neuroendocrine carcinoma of the skin,especially in the eyelids. In this report, the clinical history and treatment course of 2 patients with MCC of the eyelid were reviewed and summarized. Patient 1 with primary MCC of eyelid was treated with complete surgical excision, with good results. Follow-up for 7 years had shown no recurrence. Patient 2 with the eyelid relapse in situ two months after resection in another hospital, was treated with complete surgical excision again, but the tumor metastasized to the ipsilateral lymphonodi parotidici and cervical lymph nodes two months after the surgery. The patient is now going through radiotherapy and chemotherapy in oncology department. According to the review of literatures, the diagnosis was based on the pathologic evidence. Complete removal of lesion combined with postoperative radiotherapy and chemotherapy is a major means of treatment for MCC. Immunotherapy will play a more important role in the future.

目的：探讨赋能教育模式在干眼患者健康教育中的应用价值。方法：选取2017年6月至12月期间首诊于南方医科大学珠江医院眼科的干眼患者，按照完全随机分配法分为试验组(n=73)及对照组(n=73)，试验组采用赋能教育模式，对照组采用传统健康教育方式。经治疗1周、1个月、2个月及6个月后，分别随访并记录每组患者的眼表疾病指数(ocular surface disease index，OSDI)、泪膜破裂时间值(tear film break up time，BUT)，同时记录患者家庭护理(清洁睑缘、热敷、睑板腺按摩)频率以及复诊频率。结果：赋能教育组家庭护理频率及复诊频率均优于传统教育组(P<0.05)。治疗前两组OSDI和BUT差异均无统计学意义(P>0.05)，但试验组OSDI随时间的推移呈下降趋势，BUT值呈上升趋势；而对照组OSDI以及BUT值的变化均不明显。结论：运用赋能教育模式有助于提高干眼患者治疗的依从性，提高患者的家庭护理频率和复诊频率，显著改善患者的眼表情况，进而提高长期治疗效果。

Objective: To evaluate the application value of empowerment education mode in health education for patients with dry eye syndrome. Methods: Patients with dry eye syndrome were recruited from Department of Ophthalmology, Zhujiang Hospital, Southern Medical University from June 2017 to December 2017. All patients were randomly divided into the experimental group (n=73), educated with empowerment education mode, and control group (n=73), treated with traditional health education. Patients were followed up after 1 week, 1 month,2 months and 6 months, respectively. Data were collected in each follow-up visit including ocular surface disease index (OSDI), tear film break up time (BUT), the frequency of home care (cleaning eyelid margin, hot compress,palpebral gland massage) and re-visit frequency. Results: The OSDI and BUT were similar between two groups before corresponding treatment (P>0.05). After the treatment, patients in the experimental group showed a downtrend in the OSDI and uptrend in the BUT. No significant changes were found in the control group during the follow-up. The frequency of family nursing and re-visit in the experimental group was statistically higher than that in the control group. Conclusion: The application of empowering education mode can improve the compliance of dry eye patients, improve the frequency of home care and follow-up visit, and mitigate the ocular surface of patients, thereby enhancing the long-term efficacy.

目的：比较单眼发作的原发性急性房角关闭(acute primary angle closure，APAC)患者发作眼与未发作眼眼部生物学参数的差异，分析急性房角关闭发作的可能危险因素。方法：回顾性分析2008年1月至2020年3月中山眼科中心青光眼科222例45岁以上单眼发作的APAC病例。排除双眼发作、另眼有发作史及晶状体源性、外伤性等继发因素。A超测量晶状体厚度、眼轴长度，超生生物显微镜测前房深度。对单眼发作APAC患者的发作眼与未发作眼眼轴长度、前房深度、晶状体厚度、晶状体相对位置等进行统计学分析。结果：患者发作年龄为(62.57±9.14)岁。发作眼与未发作眼前房深度分别为(1.75±0.27) mm和(1.88±0.31) mm，眼轴长度分别为(22.34±0.80) mm和(22.35±0.83) mm，晶状体厚度分别为(5.14±0.38) mm和(5.17±0.42) mm，晶状体相对位置分别为0.195和0.198。发作眼前房深度较浅，晶状体相对位置较靠前，差异有统计学意义(均P<0.001)，发作眼的眼轴长度、晶状体厚度较未发作眼差异无统计学意义(P>0.05)。APAC发作年龄较小(45~59岁)的患者双眼眼轴均短于发作年龄较大(60~69、70岁以上)的患者；发作年龄70岁以上患者双眼前房深度均较浅，双眼晶状体相对位置均较靠前，差异均有统计学意义(P<0.05)。相关性分析表明APAC发作年龄较小的患者双眼眼轴均较短(P<0.001)。结论：APAC发作眼的前房较浅、晶状体相对位置靠前。短眼轴、女性与不同个体的APAC发作相关。浅前房、晶状体厚、晶状体相对位置靠前可能是高龄人群APAC发作的危险因素。

Objective: To compare the ocular biometric parameters between the acute primary angle closure (APAC) eyes and the fellow eyes as well as the risk factors associated with APAC. Methods: From January 2008 to March 2020,222 monocular APAC patients over 45 years old from the Glaucoma Department of Zhongshan Ophthalmic Center, Sun Yat-sen University were retrospectively studied. Patients with binocular attack, previous attack in the fellow eyes, and secondary factors such as lens-induced and traumatic glaucoma were excluded. Ocular biometric parameters including axial length (AL) and lens thickness (LT) were measured with A-scan ultrasound, while the anterior chamber depth (ACD) was measured by ultrasonic biological microscope. AL, ACD, LT and relative lens position (RLP) were compared between the APAC and the fellows eyes. Results: The average age of onset was (62.57±9.14) years. The ACD was (1.75±0.27) and (1.88±0.31) mm, AL was (22.34±0.80) and (22.35±0.83) mm,LT was (5.14±0.38) and (5.17±0.42) mm, and the RLP was 0.195 and 0.198 for the APAC and the fellow eyes,respectively. Compared with the fellow eyes, the ACD of the APAC eyes was shallower, and the RLP was more anterior (both P<0.001), while the differences of AL and LT were not statistically significant (both P>0.05).Furthermore, AL of patients with a younger age of onset (aged 45 to 59 years) was shorter than that of those with an older age of onset (aged 60 to 69 or over 70 years); patients with an onset age of over 70 years have shallower ACD and more anterior RLP, all statistically significant (P<0.05). In addition, correlation analysis indicated that younger onset age was significantly correlated to shorter axial length of APAC eyes (P<0.001). Conclusion:APAC eyes had shallower ACD and more anterior RLP. Shorter AL and female were associated with APAC attack between individuals. Shallower ACD, thicker lens and more anterior RLP are potential risk factors for APAC among aged population.

The unique pharmacological mechanism of diquafosol tetrasodium opens up a new direction for the medical therapies of dry eye. This article reviews the clinical therapeutic effect and research progress of diquafosol tetrasodium for the past few years.

目的：观察强脉冲光(intense pulse light，IPL)治疗睑板腺功能障碍(meibomian gland dysfunction，MGD)性干眼的临床效果。方法：选取2019年10月至2019年12月在东莞市东南部中心医院眼科门诊就诊的MGD性干眼患者64例(64只右眼)，随机分为对照组与观察组，每组32例。对照组采用睑板腺按摩联合常规药物治疗，观察组采用IPL联合睑板腺按摩及常规药物治疗，两组疗程均为6周；观察两组患者治疗前后干眼症状、体征及睑板腺功能变化。结果：治疗后两组干眼症状、体征及睑板腺功能均较治疗前明显改善，差异有统计学意义(P>0.05)；观察组治疗后2、4周干眼症状、体征及睑板腺功能评分改善优于对照组，差异有统计学意义(P<0.05)；治疗后6周两组各项观察指标差异无统计学意义(P>0.05)。经过6周治疗，观察组有效率为87.5%(28/32)，对照组有效率75%(24/32)，差异有统计学意义(P=0.021)。治疗期间两组均未发生不良反应。结论：IPL联合睑板腺按摩对MGD性干眼能有效减轻眼部不适症状、改善睑板腺功能，较单纯睑板腺按摩起效更快、效果更佳。

Objective: To observe the clinical effect of intense pulse light (IPL) on MGD dry eyes. Methods: Sixty-four patients(64 right eyes) with MGD dry eye from October 2019 to December 2019 were collected and randomly divided into control group (n=32) and observation group (n=32). The control group was treated with meibomian gland massage combined with conventional medicine, while the observation group was treated with IPL combined with meibomian gland massage and conventional medicine. The course of treatment of both groups was 6 weeks. The dry eye symptoms, dry eye signs and meibomian gland function changes were observed before and after treatment in both groups. Results: The dry eye symptoms, physical signs and meibomian gland function of the two groups after treatment were significantly improved compared with those before treatment (P>0.05). The improvement of dry eye  symptoms, physical signs and meibomian gland function in observation group were better than those of the control group at two and four weeks after treatment (P<0.05), while there was no statistically significant difference between the two groups at 6 weeks after treatment (P>0.05). The effective rate in observation group was 87.5% (28/32) after 6 weeks treatment, while control group was 75% (24/32), the difference was statistically significant (P=0.021). No adverse reactions occurred in both groups during the treatment. Conclusion: IPL combined with meibomian gland massage can effectively reduce the ocular discomfort and improve the function of meibomian gland in MGD dry eyes,which is faster and more effective than meibomian gland massage alone.
