Objective: To analyze the status of medical emergencies of patients in ophthalmic hospitals and put forward suggestions on their prevention and control measures. Methods: The medical emergencies of 82 patients in ophthalmic hospitals in 2017 and 2018 was been analyzed retrospectively, and the characteristics and treatment of emergencies as well as the metastasis and progression of the disease in patients were analyzed specifically.Results: Medical emergencies were caused by druginduced adverse reaction (n=38, 46.3%), syncope (28.0%), cardiovascular emergency (8.3%), accidents (6.1%) in sequence. Fluorescein sodium (n=16, 42.1%) and local anesthesia drugs for nerve block (n=7, 18.4%) were the most common drugs related to drug adverse reaction. Most cases happened at 8:00—18:00 (n=74, 91.3%), and drug adverse reaction and cardiovascular and cerebrovascular emergencies were most common at 18:00—8:00. Medical emergencies happened in outpatient department (n=53,64.6%), wards (22.0%) and operation rooms (11.0%). There were mild emergencies (92.7%), moderate emergencies (4.9%) and severe emergencies (2.4%) in patients. Among them, 50% of patients need first aid by doctors from general hospitals or to be transferred to the general hospital for further treatment. Conclusion: Through optimizing process, shortening the hospital stay, identifying potential risks and enhancing medical workers’ awareness of safety, the risk of medical emergencies can be reduced. We should give full play to the professional advantages of anesthesiologists,improve the emergency handling capacity of the hospital, and contract the emergency services of designated general hospitals to provide rapid, accurate and efficient rescue for patients to ensure the life safety of patients.
目的：比较重力液流与主控液流2种灌注方式下行白内障超声乳化手术对青光眼患者视盘血流的影响。方法：采用随机数字表法将患者分为2组，分别为重力液流灌注组和主控液流灌注组。记录术中超声乳化累积释放能量(cumulative dissipated energy，CDE)，术后1天、1周、1个月和3个月患者最佳矫正视力(best corrected visual acuity，BCVA)、眼压、视盘血流密度及视网膜神经纤维层厚度。结果：主控液流灌注组术中CDE小于重力液流灌注组(5.6±1.3 vs 6.3±1.2，P=0.034)。术后1天重力液流灌注组视盘周围血管密度(circumpapillary vascular density，cpVD)、整个图像血管密度(whole en face image vessel density，wiVD)和视盘内血管密度(inside disc vascular density，inside disc VD)均高于主控液流灌注组(P<0.05)，其余时间点差异无统计学意义(P>0.05)。术后1周和1个月重力液流灌注组视网膜神经纤维层厚度大于主控液流灌注组(P<0.05)，术后1天和3个月未见明显差异。结论：相较于传统的重力液流灌注，主控灌注能够在青光眼患者白内障超声乳化手术中减少超声能量的使用，术后早期可减轻由术中高眼压引起的视盘炎症性充血，可以减轻对视网膜神经纤维层的影响。
Objective: To compare the influence of active versus passive phacoemulsification fluidics systems on optic disc blood flow in patients with glaucoma. Methods: Patients were divided into 2 groups by a random number table method, namely the active fluidics system group and the passive fluidics system group. The intraoperative cumulative dissipated energy (CDE) was recorded, and the best corrected visual acuity (BCVA), intraocular pressure, optic disc blood flow density and retinal nerve fiber layer thickness were measured at the follow-up of 1 day, 1 week, 1 month and 3 months. Results: During phacoemulsification, CDE in the active fluidics system group was lower than that in the passive fluidics system group (5.6±1.3 vs. 6.3±1.2, P=0.034). One day after the surgery,the circumpapillary vessel density (cpVD), whole image vessel density (wiVD) and inside disc vascular density(inside disc VD) in the passive fluidics system group were higher than those in the active fluidics system group(P<0.05), and the differences were not statistically significant at the rest of the follow-ups (P>0.05).The retinal nerve fiber layer in passive fluidics system group was thicker than that in active fluidics system group at the follow-ups of 1 week and 1 month (P<0.05), and the difference was not statistically significant at the follow-up ofs 1 day and 3 months. Conclusion: Compared with the traditional passive fluidics system, the active fluidics system can reduce the CDE during phacoemulsification surgery. It can reduce the inflammatory congestion of the optic disc caused by intraoperative high intraocular pressure on the early postoperative stage. In addition, it can also protect retinal nerve fiber layer.

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.

Objective: To compare the consistency of Kappa Angle measurements in patients with age-related cataracts using four instruments of different principles in a dark room. Methods: Sixty cases (60 eyes) of age-related cataract were adapted in the darkroom for 10 minutes. The pupil size and angle Kappa were measured by iTrace, Pentacam HR, Lenstar900 and IOLMaster700. One-way ANOVA test and Kruskal-Wallis nonparametric test were used to compare the measured data among the four instruments, and Bland-Altman analysis was used for consistency comparison. Results: The measured pupil diameters of iTrace, Pentacam HR, Lenstar900 and IOLmaster700 were 4.64±0.71 mm, 2.96±0.47 mm, 4.86±0.76 mm and 4.66±0.92 mm. The Angle Kappa sizes were 0.227±0.121 mm, 0.161± 0.09 mm, 0.2±0.124 mm, 0.203±0.104 mm. The proportion of angle Kappa larger than 0.5 mm was 3.33%, 3.33%, 1.67% and 1.67%. The measurement results of angle Kappa between Pentacam and iTrace were statistically significant (P=0.001). There was no significant difference in the measurement results of angle Kappa between Pentacam and Lenstar900, Pentacam HR and IOL-Master700 (P=0.044, 0.036). There was no significant difference in the results of angle Kappa measurement among the other three instruments. The subjective score of light intensity in the process of measurement of iTrace, Pentacam HR, Lenstar900 and IOLMaster700 showed that during the process of measurement, 60 cases (100%) experienced obvious discomfort caused by the light intensity in Pentacam HR, while 40 cases (66.67%) felt comfort in IOLMaster700. The differences among the subjective score of light intensity of four instruments were statistically significant (P<0.001). Conclusion: The consistency of the measurement results of Kappa angle between Pentacam HR and iTrace, Lenstar900, IOLMaster700 in the darkroom is relatively poor, so it is necessary to be careful to replace them in clinic.

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.

Objective: To measure the thickness of retinal ganglion cell layer and inner limiting membrane-retinal pigment epithelium layer in the macular region, and analyze its correlation with new-onset ischemic stroke. Methods: By using a prospective study, 30 healthy subjects (60 eyes) who underwent physical examination in Affiliated Hospital of Weifang Medical University from December 2021 to March 2022 were selected as the control group (Group A). Thirty age-matched patients with new-onset ischemic stroke admitted at the same time (60 eyes) were selected as the stroke group (Group B). The ganglioncelllayer (GCL) and innerlimitingmembrane-Retinalpigmentepithelium (ILM-RPE) were compared between the two groups. It included the thickness and mean GCL thickness/Mean Volume thickness of ILM-RPE (GCL/ILM-RPE thickness ratio). Results: A total of 120 eyes were included, with 60 eyes in group A and B. The average GCL thickness in group A was (83.5±4.7) μm, and the average GCL thickness in group B was (78.7±10.5) μm,and the difference between groups was statistically significant (P<0.001). The minimum thickness of GCL in group A was (80.4±4.4) μm, and the minimum thickness of GCL in group B was (70.7±16.3) μm, showing statistical significance(P<0.001). The thickness of the central subregion of ILM-RPE in group A was (247.5±19.8) μm, and the thickness of the central subregion of ILM-RPE in group B was (241.6±36.3) μm, and the difference was not statistically significant between two groups (P=0.393). The mean volumetric thickness of ILM-RPE in group A was (278.4±9.8) μm, and the mean volumetric thickness of ILM-RPE in group B was (278.5±15.3) μm, and the difference was not statistically significant (P=0.448). The GCL/ILM-RPE thickness ratio of group A was (0.300 3±0.012 2), and that of group B was (0.286 2±0.028 6), showing a statistical difference between groups (P<0.001). Conclusion: Ischemic stroke affects the GCL thickness and the thickness ratio of GCL/ILM-RPE, which may be related to new-onset ischemic stroke.
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.
