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.

目的：观察黏膜瓣泪小点成形术用于治疗慢性泪小管炎的疗效。方法：回顾性病例系列研究。收集2018年1月至2020年12月中山眼科中心眼整形科就诊的44例慢性泪小管炎患者的临床资料，分析其性别、年龄、患病眼别、临床症状、泪道冲洗结果等临床特点。采用黏膜瓣泪小点成形术进行治疗，术后随访评估其疗效。结果：44例慢性泪小管炎患者以女性为主(男女比例1:3.9)，单侧发病，多累及下泪小管(上下泪小管比例1:3)，主要表现为分泌物增多、溢泪以及内眦部位红肿，结石阳性率为95.7%，病原微生物检查结果显示以放线菌感染为主(78.3%)。大部分患者术后1周内症状得到明显改善，其中1例上下泪小管炎患者于术后2个月出现上泪小管炎复发。总体治愈率为97.8%，随访时间为(20.7±10.9)个月。结论：黏膜瓣泪小点成形术治疗慢性泪小管炎的临床疗效确切，方法可靠。

Objective: To evaluate the efficacy of mucosal flap punctoplasty in patients with chronic canaliculitis. Methods: In this retrospective serial case study, the clinical data of 44 patients with chronic canaliculitis were collected from the Oculoplastic Department of Zhongshan Ophthalmic Center at Sun Yat-sen University between January 2018 and December 2020. Demographic data such as gender, age, affected eye, clinical presentations and lacrimal duct irrigation results were analyzed. The efficacy of the procedure, symptom resolution and complications were assessed. Results: Of the 44 patients, most (male:female 1:3.9) were female, and the disease most often (upper:lower 1:3) involved the lower lacrimal canaliculus of only one eye. Main symptoms included increased secretion, tearing, and swelling of the inner canthus. Stones were present in 95.7% of patients and Actinomyces israelli was found to be the most common pathogen (78.3%). Most patients’ symptoms improved significantly within 1 week after surgery. Only one patient, who had infections in both the upper and lower canaliculi, had recurrence of upper canaliculitis 2 months after the surgery. The overall cure rate was 97.8%, and the follow-up time was (20.7±10.9) months. Conclusion: Mucosal flap punctoplasty is an efficacious and reliable method in the treatment of chronic canaliculitis.

目的：利用儿童Glasgow受益调查问卷(Glasgow Children’s Benefit Inventory，GCBI)评估先天性上睑下垂手术后儿童健康相关生活质量(health-related quality of life，HRQOL)的受益，并探索受益的影响因素。方法：验证GCBI中文版评估先天性上睑下垂矫正术后长期患儿生活质量的信效度，并用其评估术后儿童HRQOL受益与性别、手术年龄、术后随访时间等相关性。结果：共178名先天性上睑下垂接受下垂矫正术后儿童完成问卷，结果显示不同性别、年龄均有正性受益，术后短期(<1年)受益更明显(P<0.05)。结论：GCBI中文版具有良好的信度和效度，适用于评估先天性上睑下垂儿童术后受益结果。先天性上睑下垂儿童接受下垂矫正术后不同性别均有正性受益，术后短期(<1年)受益更明显。

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.
