目的：评估与原发性慢性青光眼患者生活质量最具相关性的视觉指标。方法：回顾性病例系列研究。收集2010年3月至2010年8月就诊于首都医科大学附属北京同仁医院且符合入选及排除标准的原发性慢性闭角型青光眼和原发性开角型青光眼患者131例262只眼。采用Humphrey Field AnalyzerII 750i型视野分析仪对入选患者分别进行单眼Central 24-2程序和Esterman双眼视野检查程序(Esterman Binocular Visual Field Test，EBVFT)各两次检查，以保证所得数据的可靠性。使用LogMAR视力表检查并记录受试者日常单眼生活视力和日常双眼生活视力、非接触式眼压计测量眼压、直接眼底镜检查视神经的杯盘比。记录病史及目前所使用抗青光眼药物，角膜及晶状体状态。应用视功能相关生活质量量表-25(25-Item National Eye Institute Visual Function Questionnaire，VFQ-25)对患者进行生活质量评估，并将双眼日常生活视力、较好眼生活视力、较差眼视野MD(mean defect)值、较好眼视野MD值、(Esterman Visual Field Test，EVFT)效用值和VFQ-25得分进行相关性分析。结果：共有131例受试者符合入选条件。在患者生存质量的统计中，自我评价视力、近距离活动、远距离活动、社会功能、依赖程度、色觉、视野这7项得分较好，即受试者完成该7项的能力较高。VFQ-25总分与EBVFT效用值成正相关(r=0.24998，P=0.004<0.05)，与双眼日常生活视力成负相关(r=?0.37778，P<0.0001)，与较差眼视野MD值成正相关(r=0.22917，P=0.0187<0.05)，与较好眼生活视力、较好眼视野、较差眼生活视力无明显相关关系。结论：原发性慢性青光眼患者双眼视觉(双眼视野和双眼日常生活视力)和VFQ-25有良好的相关性，可用于评估慢性青光眼患者的生活质量。

Objective: To assess the correlation between the Esterman binocular visual field (EBVF) and the visual function quality of life (VFQ) in primary chronic glaucoma patients. Methods: It is a retrospective case series study.One hundred and thirty-one patients, that is to say, two hundreds and sixty-two eyes, with primary chronic glaucoma satisfying the methodological criteria were recruited for this study, who were chosen from Beijing Tongren Hospital, Capital Medical University from March 2010 to August 2010. The Humphrey Field Analyzer Model II 750i (Humphrey Instruments, Zeiss Company) was used to perform an Esterman binocular visual field test (EBVFT) and bilateral monocular full-threshold central visual field testing using the 24-2 SITA Standard program. Visual acuities were examined by logarithm of the minimum angle of resolution (logMAR) scale. Intraocular pressure and cup-disc ratio were also recorded. The history with glaucoma and anti-glaucoma drugs, and the state of the cornea and crystalline lens were also remarked. All interviews were administered face to face by the same experienced interviewer, by using the 25-Item National Eye Institute Visual Function Questionnaire (VFQ-25). Agreement between the scores from these tests and the VFQ-25 was evaluated. Results: A total of 131 patients were recruited. In the statistics of the quality of life, seven domain scores of the VFQ-25 (self-assessment vision, color vision, near action, distant action, social function, mental health and peripheral vision) were better than the others, which meant the ability of completing the seven domain was higher. Substantial agreement was found between the composite score of the VFQ-25 and the Esterman test (r=0.24998, P=0.004<0.05), strong negative correlation was found between the composite score of the VFQ-25 and the binocular visual acuity of daily life (r=?0.37778, P<0.0001), and positive correlation was found between the composite score of the VFQ-25 and the MD of the worse eye (r=0.22917, P=0.0187<0.05).Conclusion: In this sample of clinic-based patients with primary chronic glaucoma, the efficiency score of the binocular visual field tests correlated well with the composite score of the VFQ-25. Binocular visual function can be well used in evaluating the quality of life of the glaucoma patients.

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 vs0.13 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.
