目的：比较硬膜外导管辅助双路置硅胶管术与传统双路置硅胶管术在泪小管断裂吻合术中的疗效。方法：随机将连云港市第二人民医院52例(52眼)行泪小管断裂吻合术的患者分成两组，使用硬膜外导管辅助双路置硅胶管术为A组(30例)；使用传统手术方式(双路置硅胶管术)为B组(22例)。比较两组患者术中置管时间、平均手术时间、鼻腔出血率、术中疼痛评分、一次性吻合成功率的差异。结果：在术中置管时间方面，A组为(11.20±3.80) min，B组为(21.50±12.60) min；在平均手术时间方面，A组为(42.70±5.50) min，B组为(62.20±15.20) min；在术中疼痛评分方面，A组为(3.10±0.80)分，B组为(4.60±1.25)分；在鼻腔出血率方面，A组为3.33%(1/30)，B组为18.2%(4/22)，以上差异均有统计学意义(均P<0.05)；但在一次性吻合成功率方面，A组有效率为93.3%(28/30)，B组有效率为86.4%(19/22)，差异无统计学意义(P>0.05)。结论：在泪小管断裂吻合术中，应用硬膜外导管辅助双路置硅胶管术较传统双路置硅胶管术，在术中置管时间、手术平均时间、鼻腔出血率、患者疼痛程度等方面具有优势，2种置管一次性成功率的差异无统计学意义，硬膜外导管辅助双路置硅胶术方法安全、可靠、优势明显，值得临床手术推广。

Objective: To compare the efficacy of bicanalicular silicone intubation assisted with epidural catheters and traditional bicanalicular silicone intubation in the anastomosis of lacrimal canaliculus rupture. Methods: Fifty-two patients (52 eyes) were randomly divided into two groups. Patients in group A (30 cases) were treated by bicanalicular silicone intubation assisted with epidural catheters, while patients in group B (22 cases) were treated with conventional operation (bicanalicular silicone intubation). The intubation time, average operation time, nasal bleeding rate, intraoperative pain score and one-time success rate were compared between the 2 groups. Results: Intubation time in group A was (11.20±3.80) min and that in group B was (21.50±12.60) min(P<0.05). The mean operation time of group A was (42.70±5.50) min and that of group B was (62.20±15.20) min(P<0.05). Intraoperative pain score was 3.10±0.80 in group A and 4.60±1.25 in group B (P<0.05). The rate of nasal hemorrhage was 3.33% (1/30) in group A and 18.2% (4/22) in group B (P<0.05). With respect to one-time anastomosis success rate assessment, the effective rate was 93.3% (28/30) in group A, and 86.4% (19/22) in group B (P>0.05). Conclusion: During lacrimal canalicular anastomosis, bicanalicular silicone intubation assisted with epidural catheters is superior to bicanalicular silicone intubation in intubation time, average operation time, nasal bleeding rate and pain degree. There is no significant difference between the two methods in one-time success rate. Bicanalicular silicone intubation assisted with epidural catheters is safe, reliable, and worthy of promotion.

Objective: To evaluate the effectiveness of an artificial intelligence-assisted diagnostic system for cataract screening in community. Methods: A prospective observational study was carried out based on a telemedicine platform. Patient history, medical records and anterior ocular segment images were collected and transmitted from community healthcare centers to Zhongshan Ophthalmic Center for evaluation by both ophthalmologists and artificial intelligence-assisted cataract diagnostic system. Results: Of all enumerated subjects, 35.7% were male and the median age was 66 years old. Of all enumerated slit-lamp images, 98.7% met the requirement of acceptable quality. This artificial intelligence-assisted diagnostic system achieved an AUC of 0.915 for detection of severe cataracts in the external validation dataset. For subjects who were advised to be referred to tertiary hospitals by doctors, 80.3% of them received the same suggestion from this artificial intelligence-assisted diagnostic system.Conclusion: This artificial intelligence-assisted cataract diagnostic system showed high applicability and accuracy in community-based cataract screening and could be a potential model of care in community-based disease screening.

目的：评价手术视频辅助Wetlab眼睑手术教学的效果。方法：回顾性分析2021年4月至2021年9月在中山大学中山眼科中心住院医师规范化培训学员中使用全眼模型开展Wetlab外眼手术教学的情况。对照组(12人)采用传统教学方法，实验组(15人)在传统教学方法的基础上引入手术视频辅助教学，对学员第3、6、9次练习视频进行评分，分析教学效果。结果：2组学员的基线水平与学习曲线相似，练习第3次到第6次之间评分提高快(对照组P3~6=0.001，实验组P3~6<0.001)，第6次到第9次之间提高速度放缓(对照组P6~9=0.007，实验组P6~9=0.012)。对照组学员在练习第3次用时更长[(80.3±16.1) min]，随着练习次数增多，用时逐渐缩短并保持稳定(P3~6=0.040，P6~9=0.886，P3~9=0.020)，而实验组学员在练习第3次用时更短[(71.7±15.0) min]，练习过程中保持稳定(P3~6=0.568，P3~9=0.519)。结论：手术视频辅助教学有助于学员熟悉手术操作，提高练习效率。

Objective: To assess the efficacy of video-assisted Wetlab eyelid surgery teaching. Methods: From April 2021 to September 2021, the porcine orbit model was used to conduct a Wetlab teaching course on eyelid surgeries among trainees of standardized training for residents in Zhongshan Ophthalmic Center, Sun Yat-sen University. The control group (12 trainees) used conventional teaching methods. Video-assisted teaching was offered to the test group (15 trainees) based on conventional teaching methods. The videos records of the 3rd, 6th, and 9th practices were scored to analyze the teaching efficiency. Results: Trainees from the 2 groups showed a simila baseline and learning curve. Rapid improvement was found between the 3rd and 6th practice (P3–6=0.001 in control group, P3–6<0.001 in test group). The increment was slower between the 6th and 9th practice (P6–9=0.007 from control group, P6–9=0.012 from test group). Longer time was required by trainees from the control group at the 3rd practice [(80.3±16.1) min]. As they practiced more, the time required gradually decreased and remained stable (P3–6=0.040, P6–9=0.886, P3–9=0.020 from control group). Trainees from the test group spent less time at the 3rd practice [(71.7±15.0) min]. The time remained stable during all practices (P3–6=0.568, P3–9=0.519 from test group). Conclusion: Video-assisted teaching can help trainees get familiar with surgical operations and improve the efficiency of practices.

Objective: To explore the effect of local anesthesia assisted with sedation and analgesia of low-dose propofol combined with remifentanil in adult strabismus surgery. Methods: This study was a prospective cohort study. Twenty-four adult patients who underwent strabismus surgery in Beijing Tongren Hospital from October 1, 2020 to May 31, 2021 were selected and divided into local anesthesia group, and sedation and analgesia group, eachwith 12 patients. All patients received local anesthesia with a mixture of 2% lidocaine 10 mL and 0.1% epinephrine 0.1 mL, and intravenous ondansetron 8 mg. Patients in the sedation and analgesia group received intravenous infusion of midazolam 1mg and sufentanil 5 μg, followed by continuous infusion of propofol 0.6–3 mg/(kg·h) and remifentanil 0.01~0.05 μg/(kg·min) to maintain Ramsay sedation score at grade II. Visual Analogue Scale (VAS), bispectral index (BIS), operator’s satisfaction score, patient’s coordination score, nausea and vomiting, oculocardiac reflex, respiratory depression, blood pressure, heart rate and the infusion rate of propofol and remifentanil during operation were recorded in these two groups. Results: In the sedative and analgesic group, the infusion rates of propofol and remifentanil were 0.6–1.8 mg/(kg·h) and 0.01–0.03 μg/(kg·min), respectively. VAS, BIS and the incidence of increased heart rate in the sedation and analgesia group were lower than those in the local anesthesia group (P<0.05); operator’s satisfaction score and the incidence of decreased blood pressure in the sedation and analgesia group were higher than those in the local anesthesia group (P<0.05); there was no significant difference in the incidence of intraoperative nausea and vomiting, oculocardiac reflex, respiratory depression, elevated blood pressure and patient’s coordination score between the two groups (P>0.05). Conclusion: In adult strabismus surgery, local anesthesia assisted with sedation and analgesia of low-dose propofol combined with remifentanil can effectively relieve intraoperative pain, which is safe and reliable.
