Objective: This study aimed to analyze the formation of ostium granulomas following endonasal endoscopic dacryocytostomy (DCR) in patients with chronic dacryocystitis and to evaluate the efficacy of excision combined with triamcinolone (TA) injection for treating ostium granulosis after endoscopic dacryocystorhinostomy. Methods: A restrospective analysis was conducted on 98 patients (115 eyes) with chronic dacryocystitis who underwent endoscopic dacryocystorhinostomy.  Postoperative growth of the ostium granulomas was monitored, and clinical characteristics were compared between patients with and without ostium granulomas. Among these, 26 cases (31 eyes) of ostium granuloma were identified and randomly assigned to either an excision combined with triamcinolone injection group (13 cases with 16 eyes) or excision-only group (13 cases with 15eyes) based on the treatment method. The effective ratebetween two groups was compared. Results: Ostium granulomas occurred in 31 eyes (26.96%). The cure rate and improvement rate in the excision combined with TA group were 93.75% and 6.25%, respectively, whereas in the excision-only group, they were 60% and 33.33%. These differences were statistically significant (< 0.05).  Conclusions: Excision combined with intralesional triamcinolone acetonide injections proved effective in promoting the regression of ostium granuloma after DCR.

音乐在眼底病领域的应用现状及展望

Music in fundus disease: current applications and future prospects

:315-322
 
音乐作为一种非侵入性的感官刺激,凭借其独特的治疗价值在医疗领域的应用日益广泛。文章综述了音乐在眼底诊疗领域的应用现状及研究进展。大量临床研究表明,音乐干预可以显著降低患者在眼科诊疗过程中的焦虑水平,改善医疗体验。在玻璃体腔注射、早产儿视网膜病变筛查、视野检查等不同临床场景中,音乐的应用均显示出积极效果。此外,在眼科模拟手术操作研究中,背景音乐的存在不仅没有对医生的手术操作造成干扰,反而可能通过调节术者的心理状态,优化手术环境。虽然音乐干预效果存在个体差异,不同患者对音乐类型、节奏和音量的偏好各异,但总体而言,作为一种安全、经济且易于实施的辅助手段,音乐疗法在眼底临床实践中展现出良好的应用前景。目前已有初步研究表明,音乐在糖尿病视网膜病变合并抑郁症的大鼠实验模型中可减少细胞凋亡并改善抑郁。未来需要开展更多严谨的随机对照试验,建立标准化的音乐干预方案,以充分发挥音乐在眼科诊疗中的积极作用。同时,也应该重视个体化治疗原则,根据患者的个人喜好和具体临床情况,制定合适的音乐干预策略。
Music, as a non-invasive sensory stimulus, has been increasingly applied in medical fields due to its unique therapeutic value. This article reviews the current applications and research progress of music in fundus examination and treatment. Extensive clinical studies have demonstrated that music intervention can significantly reduce patients' anxiety levels during ophthalmic procedures and improve their medical experience. Positive effects have been observed across various clinical scenarios, including intravitreal injections, retinopathy of prematurity screening, and visual field examinations. Furthermore, studies on simulated ophthalmic surgical procedures have shown that background music not only does not interfere with surgeons' operational performance but may actually optimize the surgical environment by regulating the operator's psychological state. Although the effectiveness of music intervention varies among individuals, with patients showing different preferences for music types, rhythms, and volumes, music therapy generally demonstrates promising potential in fundus clinical practice as a safe, economical, and easily implemented auxiliary measure. Preliminary studies have demonstrated that music can reduce cell apoptosis and improve depression in rat models of diabetic retinopathy complicated with depression. Looking forward, more rigorous randomized controlled trials are needed to establish standardized music intervention protocols to maximize the positive effects of music in ophthalmic treatment. Meanwhile, emphasis should be placed on the principle of individualized treatment, developing appropriate music intervention strategies based on patients' personal preferences and specific clinical conditions.

大型语言模型在眼科中的应用

The application of large language models in ophthalmology

:283-294
 
大型语言模型(large language models, LLMs)在眼科的应用为医疗领域带来了巨大的潜力,尤其是在提升诊断效率、优化医患沟通和促进个性化医疗方面。通过自然语言处理技术,LLMs可以协助医生进行临床数据的归纳和分析,可以结合患者的病史、影像资料和症状描述,提供精准的辅助诊断,并在复杂病例中提供参考。LLMs还可以帮助医生快速撰写病历报告,改善医疗记录管理效率。在医患沟通中,LLMs能够通过生成通俗易懂的解释,帮助患者理解疾病状况及治疗方案,缩短医生与患者之间的沟通障碍。在远程医疗场景下,LLMs可通过实时分析患者上传的图像文本信息,提供初步诊断建议,助力医生远程诊疗。个性化医疗也是LLMs的重要应用方向,借助患者的遗传数据和生活习惯,可以帮助医生制定更为精准的个性化治疗方案,并预测手术后的恢复情况。此外,LLMs可以通过与临床数据的不断交互进行自我优化,提升其在眼科诊疗中的智能化程度。尽管LLMs在眼科领域的应用前景广阔,但仍面临数据隐私、模型解释性、语言理解等方面的挑战。未来LLMs将继续作为医生的辅助工具,形成“人机协同”的诊疗新模式,为患者提供更好、更精准的医疗服务。
The application of Large Language Models (LLMs) in ophthalmology presents tremendous potential for the healthcare field, particularly in enhancing diagnostic efficiency, optimizing doctor-patient communication, and promoting personalized medicine. Through natural language processing technology, LLMs can assist doctors in summarizing and analyzing clinical data. They can integrate a patient's medical history, imaging data, and symptom descriptions to provide precise diagnostic support and reference for complex cases. LLMs can also help physicians quickly draft case reports, improving the management efficiency of medical records. In doctor-patient communication, LLMs can generate easy-to-understand explanations that help patients comprehend their conditions and treatment plans, thereby reducing communication barriers between doctors and patients. In telemedicine scenarios, LLMs can provide preliminary diagnostic suggestions by real-time analyzing images and textual information uploaded by patients, aiding doctors in remote diagnosis and treatment.
Personalized medicine is another significant application direction for LLMs. By utilizing patients' genetic data and lifestyle habits, LLMs can assist physicians in formulating more precise personalized treatment plans and predicting postoperative recovery outcomes. Additionally, LLMs can self-optimize through continuous interaction with clinical data, enhancing their intelligence in ophthalmic diagnosis and treatment. Despite the broad application prospects of LLMs in the field of ophthalmology, challenges remain, including data privacy, model interpretability, and language understanding. In the future,  LLMs will continue to serve as auxiliary tools for physicians, forming a new model of "human-machine collaboration" in diagnosis and treatment, ultimately providing better and more precise medical services to patients.

二氧化碳激光技术在眼整形外科的应用

Application of CO2 laser technology in oculoplastic surgery

:45-52
 
二氧化碳(carbon dioxide, CO2)激光通过气体混合物激发产生红外光,组织水分高度吸收后引发汽化和局部热效应,能够精确封闭小血管和淋巴管。这些特性使得CO2激光在组织切割过程中能够最大限度地减少出血,提高术中视野的清晰度,缩短手术时间,并减轻术后肿胀、瘀斑及疼痛。在眼整形外科,特别是处理眼周复杂病例方面,CO2激光展现了显著的优势。文章对CO2激光在眼整形外科中的应用进行综述,包括眼睑肿物切除、泪小管炎治疗、瘢痕治疗、皮肤松弛治疗以及眼袋去除等,旨在为临床医生和研究人员提供关于CO2激光在眼整形外科中的全面参考,帮助其了解该项技术的优势、效果及术后并发症,以更有效地应用于实践并探索未来发展。
The carbon dioxide (CO2) laser generates infrared light through the excitation of a gaseous mixture. When this infrared light is highly absorbed by tissue water, it triggers vaporization and localized thermal effects, enabling precise sealing of small blood vessels and lymphatic vessels. These properties allow the CO2 laser to minimize bleeding during tissue dissection, enhance intraoperative visual field clarity, reduce operative time, and alleviate postoperative swelling, ecchymosis, and pain. The CO2 laser has demonstrated significant advantages in oculoplastic surgery, particularly in the management of complex periorbital cases. This article reviews the applications of the CO2 laser in oculoplastic surgery, including eyelid tumor excision, treatment of canaliculitis, scar management, skin laxity treatment, and removal of eye bags. It aims to provide clinicians and researchers with a comprehensive reference on the use of the CO2 laser in oculoplastic surgery, helping them understand the advantages, effects, and postoperative complications of this technology, in order to more effectively apply it in practice and explore future developments.
