With the improvement of anatomical studies on nose-eye, imaging diagnostic technology and surgical instruments, the accumulation of surgical clinical experience, as well as the increasing emergence of a large number of clinical and basic studies on endoscopic rhino-orbital related surgery, a well-established theoretical and practical system of endoscopic nose-eye surgery has gradually been formed. This article summarized the development of endoscopic rhino-orbital surgery, and the advantages and limitations of several major surgical methods. Also, the further research was prospected.

眶尖部肿瘤为眼科罕见疾病，但因其所处位置特殊，对机体，特别是视神经功能危害极大，错误的诊断、不规范合理的治疗不仅不能解决问题，甚至会对机体造成严重的不可挽回的损害。目前针对眶尖部肿瘤的诊断、治疗多建立在医生的主观认知与经验的基础上，尚未达成共识。本文通过分析眶尖部肿瘤的临床特点，结合以往漏诊、误诊、误治的临床案例，阐述眶尖肿瘤正确诊断的关键要点；同时，结合不同临床案例，客观分析治疗方案，尤其是手术方式、路径，为眶尖部肿瘤的合理化治疗提供依据，以期规范眶尖部肿瘤的诊断和治疗，提高治疗成功率。

Although orbital apical tumor is a rare ophthalmic disease, its special location can cause great harm to the body, especially to the function of the optic nerve. Misdiagnosis and improper treatment are not only unable to solve the problem, but also irretrievably harmful to the body. At present, there is no consensus on the diagnosis and treatment of orbital apical tumors, which are mostly based on subjective cognition and experience of doctors. In this paper, the clinical characters of orbital apical tumors were analyzed through the past clinical cases of misdiagnosis and mistreatment, and the key points of proper diagnosis of orbital apical tumors were expounded. Meanwhile, by combining with different clinical cases, the treatment plans, especially the surgical approaches, were analysed to provide a basis for the appropriate treatment of orbital apical tumors, in order to standardize the diagnosis and treatment of orbital apex tumor, and improve the success rate of treatment.

Objective: To investigate the effect of medical self-crosslinking sodium hyaluronate gel on endonasal endoscopic dacryocystorhinostomy (En-DCR). Methods: A total of 219 patients with unilateral chronic dacryocystitis (CD) were selected and randomly divided into two groups: medical self-crosslinking sodium hyaluronate gel group (group A) and control group (group B). All patients underwent En-DCR. Group A received medical self-crosslinking sodium hyaluronate gel filling the ostium at the end of En-DCR, whereas group B received no treatment. Patients were followed-up for 12 months. The mucosal epithelialization of the wound, the granulation formation, bleeding, and the success rate of ostial patency were compared in the two groups. Results: Our study included 98 patients in group A and 102 patients in group B. After 2 weeks, the number of absorbable hemostatic patients who had intact mucosal epithelium lining the ostia was 86 in group A and 77 in group B. At 12 months follow up, there were 7 patients with scar (7.1%) and 8 patients with granuloma (8.2%) in group A, compared with 17 patients with scar (16.7%) and 18 patients with granuloma (17.6%) in group B. There were significant differences in scar formation and granuloma between the two groups (P<0.05). The success rate of anastomotic patency reached 90.8% (89/98) in group A whereas the success rate was 78.4% (80/102) in group B (P<0.05). The situation of postoperative bleeding in group B was similar to that in group A (P>0.05). Conclusion: The medical self-crosslinking sodium hyaluronate gel can improve the success rate of En-DCR treatment of CD through promoting the healing of anastomotic mucosa and reducing the rate of wound scar and granuloma formation.

Objective: By simulating transnasal endoscopic resection of nasolacrimal duct and lacrimal sac on cadaveric specimens with vascular perfusion, the basic process of this procedure and the anatomical relationship between nasolacrimal duct and lacrimal sac were explored, providing anatomical basis for clinical application. Methods: Five adult cadaver head specimens (10 sides in total) were used for anatomical study. The nasolacrimal duct and lacrimal sac were exposed under transnasal endoscopy, and the anatomical landmarks and their relationship with adjacent areas during the resection of nasolacrimal duct and lacrimal sac were observed. Results: Ten sides of nasolacrimal duct and lacrimal sac showed that all lacrimal sacs were located anterior and slightly lateral to the nasal mound. The roof of lacrimal sac was almost the same height as the roof of nasal mound. The body of lacrimal sac was almost located above the horizontal line of the middle turbinate axilla. The posterior inner wall of the lacrimal fossa was composed of lacrimal bone. The posterior inner side of the lacrimal bone was adjacent to the agger nasi cell. The bottom of the lacrimal sac moved downward as the membranous part of the nasolacrimal duct located in the bony part of the nasolacrimal duct. The projection of the nasolacrimal duct on the lateral nasal wall was located about 3–7 mm in front of the anterior edge of the vertical part of the uncinate process. The distance between the inferior meatus opening of the nasolacrimal duct and the anterior end of the inferior turbinate was (16±3) mm. The length of the lacrimal sac was (13.8±1.8) mm, and the length of the nasolacrimal duct was (23.2±3.6) mm. Conclusion: The transnasal endoscopic approach can fully expose and resect the nasolacrimal duct and lacrimal sac. The basic operation process and anatomical landmarks demonstrated in this anatomical study provide an anatomical reference for the clinical development of transnasal endoscopic resection of nasolacrimal duct and lacrimal sac.

Objective: The aim of this study is to observe the efficacy and safety of propofol-alfentanil-lidocaine mixture in adult patients for cataract ambulatory surgery. Methods: Thirty adult patients undergoing cataract ambulatory surgery sedated by propofol-alfentanil-lidocaine mixture from January 2021 to June 2021 were enrolled in this retrospective study (sedation group, n=30). Meanwhile, another thirty patients with similar diagnosis performed by the same surgeons under topical anesthesia were matched in this study (topical anesthesia group, n=30). The scores of intraoperative eye position, the number of surgical interruptions due to poor cooperation, surgical time, emergence time, time to discharge, changes in blood pressure, surgical experience, as well as any adverse events were compared between the two groups. Results: The surgeries were successfully completed in all patients in both groups. Compared to topical anesthesia group, patients under sedation showed less surgical interruptions and more stable hemodynamics during the surgery, as well as better surgical experience (all P<0.05). Conclusion: Sedation with propofol-alfentanil-lidocaine mixture can significantly improve the surgical experience of patients undergoing cataract ambulatory surgery without prolonging duration of the surgery.

The bleeding and pain were improved after treatment and nursing, and 68.8% patients presented with vision improvement. Conclusion: According to the characteristics of ETOCD in patients with traumatic optic neuropathy, it is of great significance to take individualized overall care, which is beneficial to help patients successfully complete the operation, reduce the incidence of complications, and promote the recovery of the patient’s healthy.

目的：分析新型冠状病毒肺炎疫情期间实时面对面线上教学(以“腾讯会议”教学为例)在医学教育中的利弊及其与医学生眼表疾病的相关性，为改进线上教育方案、预防干眼提供依据。方法：以中南大学湘雅医学院本科学生为研究对象，采用横断面研究的方法，使用问卷星收集数据，研究实时面对面线上教学的效果及对眼表疾病的影响。结果：共收集到131份有效数据，绝大多数学生(84.73%)认为实时面对面线上教学是有效的，96.18%的学生认为实时面对面线上教学达到或部分达到了学习的目的，但是实时面对面线上教学的师生互动与课堂氛围有待加强，另外网络设备问题也是实时面对面线上教学需要面对的问题。同时，调查显示实时面对面线上教学参与学生的干眼患病率达66.41%，家庭所在地、家庭人均月收入、使用设备、是否全程专注听课与干眼患病率之间无相关性。结论：新型冠状病毒疫情期间实时面对面线上教学在医学教育中是有效的，但是师生互动不足、课堂氛围不够活跃、网络连接不稳定是其主要问题。此外，实时面对面线上教学会增加干眼的发病率，需要提高护眼意识，积极预防。

Objective: To analyze the advantages and disadvantages of real-time face-to-face online teaching (taking “Tencent Conference” teaching as an example) in medical education and its correlation with ocular surface diseases during the COVID-19 pandemic, and to provide basis for improving online education programs and preventing dry eye. Methods: The undergraduate students of Xiangya School of Medicine of Central South University were selected as the research objects. The method of cross-sectional study was used to collect data using questionnaires to study the effect of real-time face-to-face online teaching and its impact on ocular surface diseases. Results: A total of 131 valid data were collected. Among them, the vast majority of students (84.73%) think real time face to face online teaching is effective, and 96.18% of the students believe that real-time face-to-face online teaching at least partly achieved the purpose of learning. However, the interaction between teachers and students and the classroom atmosphere of real-time face-to-face online teaching needs to be strengthened. In addition, network equipment is also a problem that real-time face-to-face online teaching needs to face. Meanwhile, the survey showed that the prevalence rate of dry eye among the students who participated in real-time face-to-face online teaching reached 66.41%, and there was no correlation between the incidence rate of dry eye and the location of family, the per capita monthly income of family, the equipment, and whether they paid full attention to the lectures. Conclusion: Real-time face-to-face online teaching is effective in medical education during COVID-19, but the main problems are insufficient teacher-student interaction, inactive classroom atmosphere and unstable Internet connection. In addition, real-time face-to face online teaching will increase the incidence of dry eye, so it is necessary to improve the awareness of eye protection and actively prevent it.

Objective: To assess the training effects of “Zhongshan Eye and Nose Related Diseases and Endoscopy Forums” and its influencing factors, propose targeted suggestions for training focus and teaching methods, and improve the teaching quality. Methods: Statistics of live broadcast platform data and custom-designed questionnaires were used to inquire the participants enrolled in the 16 sessions of “Zhongshan Eye and Nose Related Diseases and Endoscopy Forums” from June 2020 to May 2022 for their feedbacks on training effects. The influence of their professions, titles, regions and other factors on the training effects was analyzed. Results: A total of 7 899 participants were enrolled in “Zhongshan Eye and Nose Related Diseases and Endoscopy Forums”, and the total live broadcast person-time was 27 634. Associate senior doctors (30.2%, 2 382) and attending doctors (32.9%, 2 597) accounted for the largest proportion. The number of participants gradually increased from 269 in the first session to 2 537 in the 16th. The topics with the largest number of participants and the greatest gains were applied anatomy and imaging, thyroid associated ophthalmopathy, and lacrimal duct diseases. Through the questionnaire study, 75.4% (95/126) of the participants thought that what they had learned in the forums was very important for their future clinical work; 84.1% (106/126) of the participants applied the knowledge to improve their daily clinical work; 96.0% (121/126) of the participants were willing to participate in the offline practice of eye and nose anatomy classes held by Zhongshan Ophthalmology Center. In terms of the role of the learned knowledge in the future clinical work, the proportion of associate senior doctors and attending doctors who thought "very useful" was significantly higher than that of senior doctors. In terms of whether to apply the knowledge learned to daily clinical work, the proportion of associate senior doctors and attending doctors thinking “yes” was significantly higher than that of senior doctors and residents. Participants who participated in 6–16 sessions had significantly better training results than those who participated in 1–5 sessions. Conclusion: Eye and nose related diseases are attracting increasing attention in ophthalmology and rhinology. “Zhongshan Eye and Nose Related Diseases and Endoscopy Forums” are conducive to the expansion and improvement of participants’ theoretical knowledge, and plays a good role in the daily clinical work of doctors with eye and nose related diseases. The training effect of attending doctors and associate senior doctors is better, and the training effect of participants who participate in the forum more times is better.

患者，女，62岁，自觉右眼突出2年就诊，高血压3年。专科体格检查：右眼上睑退缩约1.5mm，左眼上睑下垂约2.5mm。提上睑肌肌力右眼13mm，左眼9mm。完善眼眶CT及头颅磁共振，未见异常。查阅文献，初步诊断为假性正负眼睑综合征。假性正负眼睑综合征符合赫林定律。通过左眼抬高试验发现右眼上睑退缩明显好转，安排左眼手术。术中发现左眼提上睑肌腱膜撕脱约7mm，故行左眼提上睑肌前徙复位术，术后双眼上睑均回归正常位置且两边对称。假性正负眼睑综合征最常见的病因是重症肌无力，其他原因还包括甲状腺相关眼病、先天性上睑下垂、动眼神经麻痹、老年性上睑下垂及上睑成形术并发症等。临床工作中需抓住疾病的蛛丝马迹，真正做到诊疗如棋、破局而立，使患者得到精准的治疗。

A 62-year-old female patient presented with right eye protrusion for 2 years and hypertension for 3 years. Physical examination showed that the upper eyelid retraction of the right eye was about 1.5 mm, and the ptosis of left eye was about 2.5 mm. The levator upper eyelid muscle strength was 13 mm in the right eye and 9 mm in the left eye. Orbital CT and cranial MRI were completed, and no abnormalities were found. A preliminary diagnosis of pseudo plus-minus lid syndrome was made by literature review. Pseudo plus-minus lid syndrome conforms to the Herring’s law. The upper eyelid retraction of the right eye was significantly improved by the left eye elevation test. During the left eye surgery, it was found that the left levator aponeurotic was avulsed about 7 mm. so the left levator aponeurosis was repositioned. After the operation, the upper eyelids of both eyes returned to the normal position and both sides were symmetrical. The most common cause of pseudo Plus—Minus Lid Syndrome is myasthenia gravis. Other causes include thyroid-associated ophthalmopathy, congenital ptosis, oculomotor nerve palsy, senile ptosis, and complications of blepharoplasty. In clinical work, we need to grasp the clues of the disease, truly achieve the diagnosis and treatment like chess, break the game and stand, so that patients can get accurate treatment.

木村病(Kimura disease，KD)是一种罕见的、病因不明的、可能由免疫介导的慢性进行性炎症性疾病。本文分析1例8岁的男性患者，因左眼无痛性上睑下垂、影像学提示双眼泪腺占位、血象提示嗜酸性粒细胞及免疫球蛋白E(immunoglobulinE，IgE)水平升高、病理提示大量嗜酸性粒细胞浸润，被最终诊断为累及双侧泪腺的KD。行左眼眶肿物切除术后，对患者随访6个月期间未见复发。

Kimura disease (KD) is a rare chronic progressive inflammatory disease of unknown etiology that may be immunemediated. Herein, we analyze an 8-year-old male patient who was diagnosed with painless ptosis in the left eye, double tear glands on imaging, elevated levels of eosinophils and immunoglobulin E (IgE) on blood, and massive eosinophil infiltration on pathology. The final diagnosis was Kimura disease involving bilateral lacrimal glands. After resection of the left orbital tumor, no recurrence was observed in the six months postoperation follow-up

眼眶骨折是外伤性疾病常见的眼眶并发症，部分需要行眼眶骨折修复手术治疗。不同材料的植入物，是影响手术效果和预后的重要因素之一。植入物的选择国内外至今尚未有统一的标准。目前临床上使用的植入材料多为异质材料，有不可吸收材料和可吸收材料两类。不可吸收材料使用最多的是钛网和高密度多聚乙烯(Medpor)。可吸收材料主要是各类高分子聚合物。这两类材料在临 床的使用过程中都表现出了不同的优缺点，通过查阅近5年的相关报道，对比这两类材料的优缺点，可以为临床医生的选择提供一些参考。

Orbital fracture is a common orbital complication of traumatic diseases, and some of them need to be treated by orbital fracture repair surgery. Implants of different materials are one of the important factors affecting the surgical outcome and prognosis. There is no uniform standard for the selection of implants at home and abroad. At present, most of the implant materials used in clinical practice are heterogeneous materials, including non-absorbable materials and absorbable materials. The most commonly used non-absorbable materials are titanium mesh and high-density polyethylene (Medpor). Absorbable materials are mainly all kinds of macromolecular polymers. These two types of materials have shown different advantages and disadvantages in clinical. By reviewing the relevant reports recent 5 years, and comparing the advantages and disadvantages of these two types of materials, we can provide some references for clinicians to choose from.
