Objectives: To evaluate the clinical value of peripheral retinal diseases in myopic patients examined by 200-degree ultra-wide field laser ophthalmoscope (Daytona). Methods: This was a prospective case-control study. We collected 1 000 myopic patients (2 000 eyes) who were scheduled to undergo refractive surgery in Aier Eye Hospital. They were examined by 200-degree ultra-wide field laser ophthalmoscope (Daytona) with non-mydriasis and three-mirror contact lens with mydriasis. The examination results were recorded and statistically analyzed. Results: A total of 230 cases (310 eyes) with peripheral retinopathy were found by 200-degree ultra-wide field laser ophthalmoscope (Daytona). The positive rate was 15.50%; 242 cases (322 eyes) with peripheral retinopathy were found by three- mirror contact lens, and the positive rate was 16.10%. The two methods were consistent in the detection of peripheral Retinopathy in myopic patients (the Kappa value is between 0.8 and 1.0). Conclusion: 200-degree ultra-wide field laser ophthalmoscope (Daytona) is an effective and rapid method for detecting peripheral retinopathy. It provides a broad clinical application prospects for peripheral retinopathy screening before refractive surgery.

目的：了解干眼患者自我护理能力水平并分析其影响因素。方法：选取2022年2月—6月在中山大学中山眼科中心就诊的干眼患者为研究对象，采用一般资料调查表、自我护理能力量表、一般自我效能感量表对患者进行调查分析。结果：共调查293例干眼患者，其自我护理能力评分为(113.34±9.98)分，处于中等水平。相关性分析中干眼患者的自我护理能力总分与自我效能感得分呈正相关(r=0.421，P<0.001)，多重线性回归分析显示，累计屏幕使用时间>10 h/d、合并全身疾病、低自我效能感评分是干眼患者自我护理能力的危险因素(P<0.05)。结论：干眼患者自我护理能力水平处于中水平，仍需加强。医护工作者在工作中应重点关注屏幕使用时间长、合并全身疾病及自我效能感低的患者，并制定相应的护理对策，以改善患者的自我护理能力水平。

Objective: To understand the self-care ability of patients with dry eye and analyze its infuencing factors. Methods: A total of 293 patients with dry eye were selected from Zhongshan Ophthalmic Center, Sun Yat-sen University from February 2022 to June 2022, the general data Questionnaire the general self-efcacy scale, and the self-care ability scale survey were collected. Results: A total of 293 patients with dry eye were surveyed, and the self-care ability score was 113.34±9.98, which was at the medium level. The total score of self-care ability, the scores of self-concept, self-care responsibility, health knowledge level and self-care skills of patients with dry eye were positively correlated with the scores of self-efcacy (r=0.421, all P<0.001).Multiple linear regression analysis showed that cumulative screen usage time>10 hours/day, comorbid systemic diseases, and low self-efficacy scores were risk factors for self-care ability in patients with dry eye (P<0.05). Conclusions: Te self-care ability of patients with dry eye disease is at a medium level, and still needs to be strengthened. Medical workers should focus on patients with prolonged screen usage, comorbid systemic diseases, and low self-efficacy in their work, and tailor relevant nursing strategies to improve their self-care abilities.

Objective: To investigate the practical effect of the integrated group cooperation model in managing patients with fundus diseases in day surgery. Methods: 582 patients with fundus disease who underwent day surgery from January to June in 2022 were included as the control group, and 633 patients with fundus disease who underwent day surgery from January to June in 2023 were selected as the study group. The control group implemented the overall responsibility nursing system, while the study group carried out the collaborative management model, integrating medical and nursing for the entire process of patient management. Chi-square test and T-test were used to compare the differences of perioperative nursing knowledge, health education awareness, satisfaction, emergency ophthalmological consultation rate within 24 hours of discharge, follow-up rate within 24 hours of discharge, and nurses' sense of professional benefit between the two groups. Results: The awareness of health education in the study group was higher than that in the control group, and there was significant statistically difference between two groups (t=–18.47, P<0.05). The satisfaction of patients in the study group was higher than that in the control group, and there was significant statistically difference between two groups (t=–4.005, P ＜ 0.05). The follow-up rate within 24 hours after discharge was 100% in the study group and 98.1% in the control group, and the difference was statistically significant (χ2=12.073, P<0.05). The incidence of ophthalmic emergencies within 24 hours of discharge in the study group was 0.94%, while in the control group it was 1.89%. There was no statistically significant difference between the two groups (χ2= 1.951, P=0.222). The perceived benefit score of nurses after implementation was higher than that before implementation, and there was statistically significant between two groups (t=–6.637, P<0.05). Conclusions: The medical and nursing integrated group cooperation management model is used to manage the entire perioperative process of patients undergoing day surgery in fundus surgery. This model can improve patients' medical experience, enhance their compliance with ophthalmic surgery, ensure their safety. At the same time, it can enhance the senses of professional benefits for nurses.

Background: To analyze the morphological changes of meibomian glands in patients with recurrent and primary meibomian gland cyst under in vivo confocal microscope (IVCM). Methods: A cross-sectional study was performed in Shantou International Eye Center from September 2018 to April 2019. Ten patients with recurrent meibomian cyst, 10 patients with primary meibomian cyst and 10 control subjects were selected in this clinical trial. All subjects received routine ophthalmologic examination and IVCM examination. IVCM examination parameters included open area of meibomian gland, and the maximum and minimum diameter of meibomian gland opening. Relevant parameters were analyzed and statistically compared among different groups. Results: The average minimum diameter of meibomian glands opening in the recurrent meibomian gland cyst group was (109.08±49.96) μm, the average maximum diameter of meibomian glands opening was (144.95±68.10) μm, and the median open area of meibomian gland was 11 621.62 (3 976.49–24 828.82) μm² . In the primary meibomian gland cyst group, the average minimum diameter of meibomian glands opening was (101.53±29.55) μm, the average maximum diameter of meibomian glands opening was (130.08±45.21) μm, and the median open area of meibomian gland was 10 615.07 (5 813.29–18 275.44) μm² . The opening of meibomian glands in both the recurrent and primary meibomian gland cyst groups was enlarged, which significantly differed from that in the control group (both P<0.05). No statistical significance was noted between the recurrent and primary meibomian gland cyst groups (P>0.05). The acinus structure around the gland tube was manifested with serious hypertrophic scar complicated with inflammatory cell infiltration. Conclusion: IVCM can detect the morphological changes of meibomian glands in meibomian gland cyst patients. The IVCM findings of recurrent and primary meibomian gland cyst are different.

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.
