目的：探讨原发性慢性闭角型青光眼(chronic primary angle-closure glaucoma，CPACG)患者的视网膜血流密度(vessel density，VD)与视野缺损程度的相关性。方法：光学相干断层血管成像技术(optical coherence tomography angiography，OCTA)测量89例(112眼)视野缺损的CPACG患者的黄斑区VD、视盘旁VD，分析VD与视野缺损程度的相关性。结果：视盘旁VD与视野缺损程度成负相关(r>–0.728，P<0.05)。黄斑浅层总VD的受试者工作曲线(receiver operating characteristic，ROC)及曲线下面积(area under the curve，AUC)为0.874。在控制年龄、眼压及视力的情况下，黄斑总浅层VD每降低1%，视野平均缺损(mean deviation，MD)值增加–0.639 dB。结论：CPACG患者VD与视野缺损呈线性负相关，OCTA可以方便无创地观察青光眼患者眼底血流情况，在视野缺损前发现视网膜VD降低，从而可以作为CPACG早期诊断的参考指标。

Objective: To investigate the correlation between the retinal vessel density (VD) and the degree of visual field loss in chronic primary angle-closure glaucoma (CPACG). Methods: Eighty-nine CPACG patients (112 eyes) with different degrees of visual field loss were measured with optical coherence tomography angiography (OCTA) for macular VD and para-optic microcirculation VD, and the correlation between them and the degree of visual field defect were analyzed. Results: There was a negative correlation between the VD of the microcirculation in each zone next to the optic disc and the degree of visual field loss (r>–0.728, P<0.05). The receiver operating characteristic (ROC) and area under the curve (AUC) of the total VD of the superficial macula is 0.874. Under the condition of controlling age, intraocular pressure and vision, for every 1% decrease in the total superficial macular VD, the average visual field defect mean deviation (MD) value increases –0.639 dB. Conclusion: The VD of CPACG patients is linearly negatively correlated with visual field defects. OCTA can conveniently and non-invasively observe the blood flow of the fundus in patients with glaucoma. It is found that the retinal VD is reduced before visual field defects, which can be used as a reference index for early diagnosis of CPACG.

目的：了解原发性开角型青光眼(primary open angle glaucoma，POAG)患者视野缺损的进展情况，探讨其发生进展的相关危险因素。方法：回顾性分析2014年1月至2018年7月就诊于北京大学第三医院眼科并有至少4次视野检查的POAG患者。按照患者首次视野检查的平均偏差或平均缺损进行分期。将历次随访视野检查的平均偏差或平均缺损与时间进行线性回归分析，取其斜率(dB/年)。根据平均偏差或平均缺损的斜率将患者分为进展组与无进展组。分析患者视盘周围视网膜神经纤维层(retinal nerve fiber layer，RNFL)厚度损害位置、平均随诊间隔时间、基线视野分期等因素与青光眼视野缺损进展的关系。结果：共纳入128例患者(252只眼)，其中129眼使用Octopus视野计检查随访，基线视野缺损值为(10.91±5.76) dB；123眼使用Humphrey视野计，基线视野偏差值为(–10.62±6.89) dB。视野缺损早、中、晚期的比例分别为26.19%、36.51%和37.30%。进展组31只眼(12.30%)，无进展组221只眼(87.70%)。上下方RNFL都存在重度损害的患者，其视野缺损更易进展(P<0.001)。平均随诊间隔时间≤4个月的患眼，发生进展的比例高于平均随诊间隔时间>4个月的患眼(P=0.058)。基线视野分期、年龄、性别、总随访时间与视野缺损进展未见显著相关性。结论：青光眼患者的视功能损害出现恶化是普遍存在的。上下方RNFL均存在重度损害、随诊间隔时间短与视野缺损进展相关。视神经结构的改变与功能损害具有相关性，结构改变的方位对功能损害进展有提示功能。规律随诊对病情监测有重要意义，对于可能快速进展的患者，应缩短随诊间隔时间。

Objective: To investigate the progression of visual field defect in primary open angle glaucoma (POAG), and to explore the related risk factors for its progression. Methods: A retrospective analysis was performed on patients with POAG who had at least 4 visual field examinations in the Department of Ophthalmology, Peking University Third Hospital from January 2014 to July 2018. The visual field was staged according to the mean deviation or mean defect of the first visual field examination. Linear regression analyses of mean deviation or mean defect were performed against time, and corresponding regression slopes (in decibels per year) were calculated. Patients were divided into progressive and non-progressive groups according to the mean deviation slope or mean defect slope. The relationship between retinal nerve fiber layer (RNFL) thickness lesion location, mean follow-up interval, baseline visual field staging, and the progression of visual field defect in glaucoma were analyzed. Results: A total of 128 patients (252 eyes) were included. Among them, 129 eyes were followed up with an Octopus perimeter, and the average mean defect value of the baseline visual field was 10.91±5.76 dB; while the other 123 eyes were followed up with a Humphrey perimeter, and the average mean deviation value of the baseline visual field was –10.62±6.89 dB. The proportion of early, middle and late visual field defects was 26.19%, 36.51% and 37.30%. There were 31 eyes (12.30%) in the progressive group and 221 eyes (87.70%) in the non-progressive group. Patients with severe damage to both the upper and lower RNFLs had more visual field defects (P<0.001). Patients with an average follow-up interval ≤4 months had a higher rate of progression than those with an average follow-up interval >4 months (P=0.058). There were no significant differences in baseline visual field stage, age, gender, and total follow-up time between the progression and progression-free groups. Conclusion: Deterioration of visual function impairment is common in glaucoma patients. The progression of visual field defects is associated with severe impairments which are present both in the upper and lower RNFLs, and short follow-up intervals. Optic nerve structure changes are related to functional impairment, and the location of structural changes is suggestive of functional impairment progression. Regular follow-up visits are of great significance for disease monitoring. For patients who may progress rapidly, the follow-up interval should be shortened.

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.

目的：探讨正常眼压性青光眼(normal tension glaucoma，NTG)患者睡眠体位与其双眼不对称损害的关系。方法：纳入2014年1月至2018年9月在温州青光眼进展研究(Wenzhou Glaucoma Progression Study，WGPS)项目中的NTG患者。眼部主要检查有视野和光学相干断层扫描(optical coherence tomography，OCT)。睡眠体位数据通过基线睡眠体位问卷获得。根据侧卧位睡眠偏好，将NTG患者眼部参数分为卧位高侧眼和卧位低侧眼进行讨论；根据双眼不对称损害，将患者眼部参数分为较好眼和较差眼讨论。双眼不对称损害定义为双眼视野平均偏差(mean deviation，MD)差值>6 dB或杯盘比差值>0.2。结果：共纳入158例NTG患者，最长随访时间为48个月，其中122例(77.22%)患者存在睡眠偏好；存在睡眠偏好的患者中，83例(68.03%)患者存在侧卧位偏好；存在侧卧位偏好的患者中，大多数患者偏好右侧卧位[右vs左：59 (71.1%) vs 24 (28.9%)，P<0.001]。对存在侧卧位偏好的患者进行分析，发现卧位高侧眼与卧位低侧眼眼部参数之间，差异无统计学意义(P>0.05)；卧位低侧眼的视野进展速率[视野指数(visual field index，VFI)、MD]慢于卧位高侧眼(0.48%±1.66%/年 vs ?0.45%±3.07%/年；0.54±0.96 dB/年 vs 0.2±1.15 dB/年)，差异无统计学意义(P=0.086，P=0.308)。对同时存在侧卧位偏好及双眼不对称损害的患者进行分析，发现卧位高侧眼与卧位低侧眼的眼部参数之间，差异无统计学意义(P>0.05)；卧位低侧较好眼的个数及占比高于卧位低侧较坏眼[23 (57.5%) vs 17(42.5%)]，但差异无统计学意义(P=0.132)；卧位低侧眼的视野进展速率(VFI、MD)也慢于卧位高侧眼(1.19%±1.65%/年 vs ?0.86%±3.65%/年；0.71±1.13 dB/年 vs 0.13 dB/年)，但差异无统计学意义(P=0.064，P=0.419)。结论：存在睡眠体位偏好的NTG患者中，约68%存在侧卧位偏好；存在侧卧位偏好的患者中，约70%偏好右侧卧位。但本研究并未发现睡眠体位与青光眼患者双眼不对称损害及其疾病进展存在相关性。

Objective: To investigate the association between lateral decubitus position (LDP) and asymmetric loss in normal tension glaucoma (NTG) patients. Methods: NTG patients were enrolled from Wenzhou Glaucoma Progression Study (WGPS) in Jan. 2014 to Sep. 2018. The main eye examinations included visual field test and optical coherence tomography (OCT). A questionnaire to determine the preferred sleeping position was administered to each patient in the baseline. According to the LDP, the eye parameters were divided into non-dependent eyes (higher lateral eyes) and dependent eyes (lower lateral position eyes) for discussion. According to the asymmetric damage, the ocular parameters of the patients were divided into the better eyes and the worse eyes for analysis. Asymmetric loss was defined as a difference in mean deviation (MD) between the 2 eyes of at least 6 dB or disc/cup >0.2. Results: One hundred and twenty-two patients (77.22%) had sleep preferences among the 158 NTG patients who was finally recruited and the longest follow up time was 48 months. Among the patients with sleep preference, 83 patients (68.03%) preferred the lateral decubitus position. Patients who had the lateral decubitus position mostly preferred the right lateral position [59 (71.1%) vs 24 (28.9%), P<0.001]. For patients who had the lateral decubitus position, the ocular parameters between the dependent eyes and the non-dependent eyes had no statistical difference(P>0.05); the rate of visual field progression in the dependent eyes was slower than that in non-dependent eyes, but there was no statistical difference between the two groups (0.48%±1.66%/year vs ?0.45%±3.07%/year; 0.54±0.96 dB/year vs 0.2±1.15 dB/year; P=0.086, P=0.308, respectively). For patients who had the lateral decubitus position and asymmetric damage, the ocular parameters between the dependent eyes and the non-dependent eyes had also no statistical difference (P>0.05); the number and ratio of the dependent-better eye and the dependent-worse eye were 48 and 41, respectively [23 (57.5%) vs 17 (42.5%), P=0.132]; the rate of visual field progression in the dependent eyes was also lower than that in non-dependent eyes, but there was no statistical difference between the two groups (1.19%±1.65%/year vs ?0.86%±3.65%/year; 0.71±1.13 dB/year vs 0.13 dB/year; P=0.064, P=0.419 respectively). Conclusion: About 68% of NTG patients with sleep preferences preferred the lateral decubitus position; and about 70% of patients with the lateral decubitus position preferred the right side sleeping. However, this study did not find a correlation between lateral decubitus position and asymmetric visual field loss.

Objective: To evaluate the repeatability and reproducibility of quantification of macular and peri-papillary superficial capillaries in normal eyes using Cirrus HD-OCT 5000 angiography. Methods: Forty normal eyes were included in this prospective study. Angiography 3 mm × 3 mm scan protocol centered on the disc or macula of the same eye was repeated 3 times by operator A in the same period on 3 days (T1, T2, T3) within 1 week, and the FastTracTM image tracking function was turned on during the scan. Operator B repeated the same scan independently at T2 after operator A. Angio Plex MetrixTM quantification software (version 10.0) was used to automatically measure the vessel length density (VD) and vascular perfusion density (PD) of macular and peri-papillary superficial capillaries. One-way analysis of variance or nonparametric test was used to compare the VD and PD measurements of the 3 scans. The intraclass correlation coefficient (ICC) and coefficient of variation (CV) were calculated to evaluate the intra-operator repeatability. Consistent correlation coefficient (CCC), repeatability coefficient (CR), and CV were calculated to evaluate the inter-operator reproducibility. Results: There was no statistically significant difference in the measurements of VD and PD between the 3 scans of the macular and peri-papillary superficial capillaries by operator A (P>0.05). The ICC values for the 3 scans of VD and PD of the macular and peri-papillary superficial capillaries by operator A were 0.260–0.517 and 0.362~0.898, respectively. The CV values of the VD and PD of the macular and peri-papillary superficial capillaries were all <8.1%. The inter-operator CCC values of the macular and peri-papillary superficial capillaries were 0.3130–0.5665 and 0.5149~0.7801, respectively; the CR values of the VD and PD of macula were 3.2212–4.6399 and 0.0574–0.0832, respectively; the CR values of the VD and PD of optic disc were 2.0675–4.0630 and 0.0447–0.0730, respectively. The CV values of macular were all <9.0%, and the CV values of optic disc were all <6.9%. Conclusion: The macular and peri-papillary superficial capillaries parameters in the same period on different days have a good repeatability and reproducibility, while the superficial macular blood flow parameters have relatively poor repeatability and reproducibility.

目的：通过在人小梁网细胞(human trabecular meshwork cell，HTMC)中过表达沉默信息调节因子2相关酶1(silent information regulator 1，SIRT1)，探讨SIRT1对氧化应激下HTMC功能的影响。方法：将SIRT1过表达慢病毒和GFP阴性对照慢病毒按照最佳(multiplicity of infection，MOI)分别转染入HTMC，并用实时定量PCR法对SIRT1是否在细胞中过表达进行验证。实验分为以下4组：正常组、H2O2组、H2O2+Lv-SIRT1-OE(过表达)组、H2O2+Lv-GFP组，分别采用Transwell法和CCK8法检测氧化应激下HTMC的迁移能力和活性。两组间比较采用独立样本t检验。结果：在正常组、H2O2组、H2O2+Lv-SIRT1-OE组、H2O2+Lv-GFP组这4组中，Transwell实验结果分别为436±73、254±25、510±51、327±46，H2O2+Lv-SIRT1-OE组分别与H2O2组和H2O2+Lv-GFP组差异均有统计学意义(P<0.01)。CCK8法结果显示，H2O2+Lv-SIRT1-OE组分别与H2O2组和H2O2+Lv-GFP组相比差异均有统计学意义(P<0.01)。H2O2+Lv-SIRT1-OE组分别与H2O2组和阴性对照组(H2O2+Lv-GFP)相比，Bax表达水平明显下降，Bcl-2表达水平明显提高，差异均有统计学意义(P<0.01)。ROS活性氧测定显示H2O2+Lv-SIRT1-OE组比H2O2组的细胞活性氧水平显著降低(P<0.05)。结论：在HTMC中过表达SIRT1能有效降低氧化应激对HTMC迁移能力和活性的影响，从而对HTMC起到一定的保护作用，为后续研究SIRT1保护氧化应激下HTMC的调控机制打下基础。

Objective: To explore the effect of Silent Information Regulator 1 (SIRT1) on cell function of human trabecular meshwork cell (HTMC) under oxidative stress by overexpressing SIRT1 in HTMC. Methods: This is an experiment research. HTMCs were transfected with SIRT1-ovexpressed lentivirus and GFP-negative control lentivirus (Lv-GFP) at the optimal multiplicity of infection (MOI). Real-time quantitative PCR was used to verify whether SIRT1 was overexpressed in HTMC. The following experiments were divided into four groups: normal control group, H2O2 group, H2O2+Lv-SIRT1-OE group, H2O2+Lv-GFP group. Cell migration was detected by transwell assay. Cell viability was detected by CCK8 assay. Student’s t-test was used for two groups. P<0.05 was set as statistical signi?cance. Results: The number of migration per well of normal control group, H2O2 group, H2O2+Lv-SIRT1-OE group, H2O2+Lv-GFP group were 436±73, 254±25, 510±51, 327±46, respectively. Compared with H2O2 group and H2O2+Lv-GFP group, transwell assay demonstrated that the number of migrations per well of H2O2+Lv-SIRT1-OE group significantly increased (P<0.01). Likewise, CCK8 assay indicated that cell viability of H2O2+Lv-SIRT1-OE group was higher than both of H2O2 group and H2O2+Lv-GFP group (P<0.01). Compared with H2O2+Lv-SIRT1-OE group and negative control group (H2O2+Lv-GFP), the expression level of Bax decreased significantly, and the expression level of Bcl-2 increased significantly (P<0.01). ROS assay showed that the ROS level in H2O2+Lv-SIRT1-OE group was significantly lower than that in H2O2 group (P<0.05). Conclusion: SIRT1 overexpressed in HTMC can effectively reduce the effect of oxidative stress on migration ability and proliferation activity of HTMC, which lays a foundation for further study on the regulatory mechanism of SIRT1 protecting HTMC under oxidative stress.

目的：了解儿童罹患青光眼的疾病类型、特点，更好地做到早期发现早期治疗。方法：收集北京同仁医院2014—2019年度834例0~18周岁住院接受抗青光眼手术的患者，回顾性分析患者的人群特点与疾病构成特点。结果：834例患者中，原发青光眼397例(47.6%)，继发青光眼429例(51.4%)。另有8例无法明确诊断青光眼类型。原发青光眼中以原发先天性青光眼最常见，继发青光眼中以白内障术后继发青光眼为主，两种类型的青光眼占总患者数的50%。结论：儿童罹患青光眼的疾病种类繁多，其中原发先天青光眼与白内障术后继发青光眼最常见，重视婴幼儿先天青光眼的筛查，监测儿童白内障术后眼压有助于早期发现青光眼，并给予治疗，延缓儿童青光眼患者视功能的损害。

Objective: To understand the types and characteristics of glaucoma in pediatric inpatients to achieve early detection and treatment. Methods: A total of 834 patients aged 0–18 years who underwent anti-glaucoma surgery in Beijing Tongren Hospital from 2014 to 2019 were collected and their population characteristics and disease composition characteristics were retrospectively analyzed. Results: In all of the 834 cases, there were 397 patients (47.6%) with primary glaucoma and 429 (51.4%) with secondary glaucoma. The type of glaucoma could not be definitively diagnosed in 8 cases. Primary infant glaucoma and secondary glaucoma following cataract surgery accounted for above 50%. Conclusion: The causes of pediatric inpatients with glaucoma are various. Screening of primary infant glaucoma should be taken seriously and monitoring intraocular pressure after cataract surgery is also important. Early detection and treatment can prevent further visual loss of pediatric patients with glaucoma.
