目的：探索基于眼底彩照和人工智能构建冠心病智能诊断系统的可行性。方法：于2013—2014年收集广东省人民医院530例患者共2117张眼底彩照，其中冠心病217例共909张眼底彩照。根据患者有无冠心病的情况进行标记，使用Inception-V3深度卷积神经网络训练人工智能模型，随后使用验证数据判断模型的准确率。计算深度卷积网络模型的准确性、一致率、敏感性、特异性和受试者工作特性曲线下面积(area under the curve，AUC)。结果：在2117张眼底彩照中，1903张用于模型训练，214张用于模型的性能评估。在测试集中，该算法的准确性为98.1%，一致率为98.6%，敏感性为100.0%，特异性为96.7%，AUC为0.988(95%CI：0.974~1.000)。结论：眼底彩照联合人工智能技术可精准判定冠心病，该模型具备较高的敏感性和特异性，但须进一步增加样本量，使用大样本量数据验证该模型，排除过拟合的可能性。

Objective: To explore the feasibility of developing a deep learning algorithm for detecting coronary heart diseases based on fundus color photography and artificial intelligence (AI). Methods: A total of 2 117 fundus  color photographs were taken from 530 patients in Guangdong Provincial People’s Hospital from 2013 to 2014,including 909 fundus color photographs from 217 patients with coronary heart disease (CHD). According to whether the patient had coronary heart disease or not, the Inception-V3 depth convolution neural network was used to train the deep learning model, and then the validation data were used to judge the accuracy of the model. The accuracy, consistency rate, sensitivity and specificity of the deep convolution network model and the area under the working characteristic curve (AUC) were calculated. Results: Among the 2 117 fundus color photographs, 1 903 were used for model training, and 214 were used to test the accuracy of the model. In the test dataset, the accuracy of the algorithm was 98.1%, the consistency rate was 98.6%, the sensitivity was 100.0%, and the specificity was 96.7%. The AUC was 0.988 (95% CI, 0.974–1.000). Conclusion: The combination of fundus color photography and artificial intelligence can achieve the accurate diagnosis of the coronary heart disease, and the model has high sensitivity and specificity. However, future studies are warranted to validate our model and exclude the possibility of over-fitting.

Objective: To explore the application effect of quality control circle in shortening the length of outpatient visit in fundus surgery. Methods: A quality control circle group was established to set up the activity theme of shortening the duration of treatment for outpatient patients of fundus surgery, and 484 patients who visited outpatient clinics outside fundus in September 2020 were selected as the pre-activity research objects. In December 2020, 976 patients who visited fundus surgery outpatient department were the subjects of the post-activity study. We analyzed the duration of treatment and the reasons for poor medical experience of patients before the intervention, formulated countermeasures for the reasons and organized and implemented them. Results: After the quality control circle activity was carried out, the mean duration of outpatient visits in fundus surgery was significantly shortened (P<0.05). With the help of the information system, the medical treatment process was optimized to improve the satisfaction of patients, and the team cohesion, enthusiasm, communication and coordination ability of the circle members were significantly improved. Conclusion: Quality control circle activities can shorten the duration of treatment for fundus surgery patients, improve patients' medical experience, enhance the comprehensive ability of the nursing team, and the improvement effect can be maintained sustainably.

Objective: To explore the prevention efficacy of auricular points plaster therapy on gastrointestinal reaction caused by fundus fluorescein angiography (FFA). Methods: We selected 583 patients who underwent fundus fluorescein angiography in the special examination department of our hospital from October 2019 to April 2020, and divided these patients into experimental group (n=298) and control group (n=285). The control group was given routine nursing measures before the examination. The experimental group was treated with auricular points plaster therapy on the basis routine nursing measures before the examination. The gastrointestinal reactions, degree of patient compliance and comfortableness during the examination were compared between the two groups. Results: The incidence of gastrointestinal reaction in the experimental group was lower than that of control group (P<0.05). The score of patient compliance degree was 2.87±0.35 in the experimental group and 2.96±0.19 in the control group, and there was a significant difference between the two groups (P<0.001). Degree of comfortableness was 3.93±0.70 in the experimental group and 3.91±0.56 in the control group. There was no significant difference between the two groups (P=0.122). Conclusion: Auricular points plaster therapy can reduce the incidence of gastrointestinal reaction caused by fundus fluorescein angiography, which is safe and reliable, easy to operate. In addition, the auricular points plaster therapy will not affect patient’s comfortness during examination, and will comply the patients to the examnination smoothly. is helpful for patients to complete the examination comfortably and safely

视网膜疾病大多以周边视网膜病变为首要表现，后者的早期诊断、监测对于视网膜疾病的治疗及预防起着至关重要的作用。以往传统眼底成像技术仅能提供20°视网膜的可视范围，即便使用蒙太奇拍摄技术，也只能采集部分眼底范围。目前眼底成像技术已步入最新的超广角时代，其所提供的眼底视野至少可达200°，并且基于该技术的超广角眼底彩色照相、荧光素血管造影、光学相干断层扫描及其血管造影等已广泛应用于临床实践中，对于诊断及评估视网膜疾病发挥重要作用，如糖尿病性视网膜病变、视网膜静脉阻塞、早产儿视网膜病变、视网膜色素变性及视网膜脱离等。本文将从超广角成像技术的产生、发展及其国内外的临床应用现状作一综述，旨在为临床工作及研究提供指导意义。

Retinal diseases primarily feature with peripheral retinopathy, and its early diagnosis as well as the later following up both play a vital role in the treatment and prevention of retinal diseases. In the past, traditional fundus imaging technology can only provide the visual range of 20 degrees. Even if montage photography technology is used, it can only partially reveal the fundus field. At present, fundus imaging technology has entered the latest era of ultra-wide-field, which provides at least 200-degree fundus field of vision. Ultra-wide-field fundus photochromy, fluorescein angiography, optical coherence tomography and angiography based on this technology have been widely used in clinical practice, and play an important role in the diagnosis and evaluation of retinal diseases, such as diabetes retinopathy, retinal vein occlusion, retinopathy of prematurity, retinitis pigmentosa and retinal detachment. This article aims to review the occurrence and development of ultra-wide-field fundus imaging technology and its clinical applications up to now to provide a relative guideline for clinic and research.

眼缺血综合征(ocular ischemia syndrome，OIS)是由一系列诱因引发的以慢性眼部低灌注为主要临床表现的眼部疾病。临床相对少见，但对视力的影响较大，其症状主要包括一过性黑朦、缺血性眼痛、永久性视力丧失等。近年来医疗美容行业逐步兴起，自体脂肪填充技术使用逐渐增多，其所引起的OIS不可忽视。本文分析1例自体脂肪填充患者术后致OIS病例，研究该类疾病眼底影像学特征。

Ocular ischemia syndrome (OIS), featuring as chronic ocular hypoperfusion, is an eye disease caused by a series of incentives. It is relatively rare in clinical practice, but has a great impact on vision. The symptoms of OIS mainly include transient amaurosis, ischemic eye pain, permanent vision loss, etc. In recent years, with the rise of the Aesthetic Medicine industry, the technology of autologous fat filling has been increasingly adopted. The OIS caused by the surgery of autologous fat filling is nonnegligible. In this paper, by means of analyzing a case that an autologous fat filling surgery resulted in the OIS, discusses features of fundus angiography of OIS.

Objective: To observe the eye position, the incidence of eye movement and the efficacy of propofol on correcting eccentric eyeball position in children undergoing examination of outpatient fundus fluorescein angiography (FFA) with inhaled sevoflurane via laryngeal mask airway. Methods: Children undergoing FFA with sevoflurane anesthesia from June 2018 to December 2019 were retrospectively reviewed. Eye position at the beginning of examination, incidence of eye movement during examination, the efficiency of propofol on correcting eccentric eyeball position during procedure, the time to resume normal activities, and adverse events were recorded. Results: Fifty-four children aged 1–9 years were included in this study. The rates of eye position from grade one to grade three at the beginning of examination were 42.6% (23/54), 51.9% (28/54), and 5.6% (3/54), respectively. The incidence of eye movement during examination was 61.1% (33/54). 13% (7/54) of children with unsatisfactory eye-position needed intervention with propofol. The efficacy of propofol (1 mg/kg) in correcting eye position was 100%. The mean time to return normal activities was 24.4 min. There were no any adverse events during the peri-anesthetic period. Conclusion: Inhaled sevoflurane via LMA can provide appropriate anesthesia for outpatient FFA in children. Children can resume daily activities soon after anesthesia. Propofol can return the incorrect eye position during examination
