目的：评估超脉冲二氧化碳(CO₂)激光治疗不同类型眼睑肿物的疗效和安全性。方法：纳入50例眼睑肿物患者，其中男12例、女38例。患者年龄4~84岁。肿物类型包括眼睑色素痣、睑黄瘤、分裂痣、眼睑疣等，其中25例累及眼睑灰线，10例肿物直径>10 mm。所有患者接受超脉冲CO₂激光治疗，并进行术后随访。治疗效果通过术后数码照片评估，同时记录术后1个月并发症发生情况。结果：50例眼睑肿物总体治愈率为92%，有效率达到100%。4例眼睑色素痣在治疗后1个月内复发。术后并发症主要包括轻微倒睫(5例)、睫毛稀疏部分缺失(4例)和瘢痕增生及色素沉着(4例)，未出现其他严重并发症。结论：对于眼睑肿物，特别是睑缘肿物及大肿物，超脉冲CO₂激光是一种更为精确、微创、安全有效的治疗方法，可作为眼睑肿物治疗的优选方案。

Objective: To evaluate the efficacy and safety of ultrapulse carbon dioxide (CO₂) laser in the treatment for various types of eyelid tumors. Methods: A total of 50 patients, including 12 males and 38 females,with eyelid tumors were included in the study The age range is  from 4 to 84 years, with an average age of 37.9±20.0 years. The tumors found in our study include eyelid pigmented nevus, xanthelasma, divided nevus, and molluscum. Among them, 25 cases involved the gray line of the eyelid,and 10 cases had a tumor diameter greater than 10 mm. All patients underwent ultrapulse CO₂ laser treatment and postoperative follow-up. The treatment outcomes were assessed through digital photos, and complications were recorded one month after surgery. Results: The total cure rate of the 50 cases of eyelid tumors in our study was 92%, with the effective rate reaching 100%. 4 cases of eyelid pigmented nevi recurred within one month after treatment, while all other patients were cured. Postoperative complications mainly included minor trichiasis (5 cases), partial sparse to absent eyelashes (4 cases), and hypertrophic scar with hyperpigmentation (4 cases). No other serious complications were reported in our study. Conclusions: For eyelid tumors, especially eyelid margin and larger tumors, the ultrapulse CO₂ laser is a more precise, minimally invasive, safe and effective treatment method. It can be used as a preferred treatment option for eyelid tumors, and should be promoted widely in clinical practice.

Aims: Divided nevus of the eyelid is a congenital pigmented nevus that impacts eyelid function and aesthetics. While surgical excision and laser ablation are current treatment options, they have limitations when dealing with large lesions. This study aims to investigate the efficacy and safety of carbon dioxide (CO₂) laser excision treatment for divided nevus of the eyelid. Methods: This retrospective study included 10 patients (5 males, 5 females) with a mean age of 23.7 years (9-54 years). All underwent CO₂ laser excision and were followed up for 12 months. Treatment outcomes were assessed through clearance and recurrence rates, evaluated using digital photography. Postoperative complications were closely monitored throughout the 12-month follow-up period. Patient satisfaction was assessed using a comprehensive questionnaire. Results:All patients presented with unilateral divided nevus of the eyelid, with lesion diameters ranging from 25 to 50 mm and heights ranging from 0.3 to 6 mm (mean: 3.93 mm). Patients received between 1 and 5 laser treatment sessions. At the 12-month follow-up, a 100% clearance rate was achieved, with no recurrence observed in any patient. All patients maintained a continuous eyelid margin with acceptable irregularity. Complications were minimal, with partial eyelash loss in 8 patients, hyperpigmentation in 2 patients, and mild upper eyelid trichiasis in 1 patient. No severe complications, such as ectropion, eyelid margin notching, corneal erosion, or significant scar hypertrophy, were reported. All patients expressed being "very satisfied" with the functional and cosmetic outcomes in a questionnaire. Conclusions: CO₂ laser excision offers a simple, precise, and effective treatment approach for divided nevus of the eyelid. This innovative technique simplifies the treatment process, achieves excellent cosmetic outcomes, and eliminates the need for skin grafting, making it a promising option for the management of large divided nevus.

Objective: To investigate the satisfaction of 5-year undergraduate students in clinical medicine with clerkship teaching and analyze its influencing factors. Methods: Anonymous online questionnaire survey was conducted. Satisfaction questionnaires were distributed to undergraduate students in the 4th year of the 5-year clinical medicine at Sun Yat- sen University who had completed clerkship in all clinical departments. Results: A total of 75 students completed the questionnaire survey. Among the most satisfactory clerkship courses, ophthalmology had the highest satisfaction rate (39 votes, 52%), followed by surgery (18 votes, 24%) and internal medicine (7 votes, 9.33%). Te top 5 options in terms of comprehensive scores for infuencing factors of teaching satisfaction are "A. Reasonable curriculum with prominent focuses", "B. High clerkship class teaching level", "C. Strong teaching staf", "D. Abundant clinical resources ", and "E. Advanced teaching methods ". When selecting the infuencing factors that rank frst (B 33.33%, A 25.86%, E 21.15%) and second (E 26.92%, B 24.56%, A 24.14%), the top three options are A, B, and E. Students atach great importance to the seting of clerkship courses, the level of clerkship courses, and the teaching methods. In terms of students' willingness to engage in ophthalmology, 5 students (6.67%) expressed great willingness, and 32 students (42.67%) expressed the possibility. Conclusions: Te seting of clerkship courses, the level of small class teaching, and the clerkship teaching method are important infuencing factors of clerkship satisfaction.

Objective: To explore the benefits of children’s HRQOL after congenital ptosis surgery using the Glasgow Children’s Benefit Inventory (GCBI) and the factors influencing the benefits. Methods: To verify the reliability and validity of the Chinese version of GCBI in evaluating the long-term life quality of children after correction of congenital ptosis, and to evaluate the correlation between the HRQOL benefit of children after surgery and gender, surgical age, postoperative follow-up time, etc. Results: A total of 178 children after congenital ptosis surgery completed the questionnaire. Different genders or ages of children with congenital ptosis both showed positive benefit after ptosis correction, and the short-term (<1 year) benefit was more obvious after surgery (P<0.05). Conclusion: The Chinese version of GCBI has good reliability and validity,and is suitable for evaluating the postoperative benefit results of children with congenital ptosis. All the children with congenital ptosis received positive benefit after ptosis correction, and the short-term benefit (<1 year) was more obvious.
