Methods: Selected 96 patients, 175 eyes, randomly divided into control group (48 cases, 86 eyes) and study group (48 cases, 89 eyes). Two groups were all given retinal laser photocoagulation treatment, while the study group continued to receive calcium dobesilate for 12 weeks after treatment. After 12 weeks, observed the eyesight, change of blood rheology of the two groups. Results: After the treatment, the patients with vision >1.0 in the study group were significantly more than the control group (χ2 =6.779, P=0.009), in the vision range of ≤0.4, 0.4~0.6, 0.7~1.0, the difference between the two groups was (χ2 =0.003, P=0.955), (χ2 =1.640, P=0.200), (χ2=2.148, P=0.143), respectively. After treatment, plasma viscosity, erythrocyte deposited, erythrocyte deformation index, fibrinogen in the study group were better than those in the control group (P<0.05). The total effectiveness in the study group was 89.9%, in the control group was 75.6%, the difference was statistically significant (χ2=6.302, P=0.012). Conclusion: The whole retinal laser photocoagulation and postoperative application of calcium dobesilate in treating the diabetic retinopathy can effectively improve eyesight and clinical curative effect, which may be associated with improving blood rheology.
大部分眼科手术/操作具有创伤小、疼痛刺激轻等特点,因此,选择眼表面麻醉即可满足手术的镇痛的需要,促进了眼科日间手术的广泛开展。其中,盐酸奥布卡因滴眼液是常用的眼科表面麻醉剂,具有麻醉起效迅速、镇痛作用强、持续时间久(约13 min)等特点,已经广泛应用在眼内手术中,在使用过程中,盐酸奥布卡因滴眼液对瞳孔及血管无影响,保证了眼内手术的安全。盐酸奥布卡因滴眼液能提供良好的眼表环境,对角膜厚度及角膜上皮厚度影响轻微,从而满足屈光手术的需要。此外,盐酸奥布卡因滴眼液能提供良好的术后镇痛,减少术后镇痛药物的使用,降低斜视术后患儿的躁动发生率。不含防腐剂的表面麻醉剂不影响麻醉剂的起效时间及镇痛效果,对眼表的影响轻微,从而创造良好的手术操作环境,提高手术效果,降低并发症和手术风险,是眼科手术中较为理想的表面麻醉药物。文章就盐酸奥布卡因滴眼液的作用机制及麻醉效果、药代动力学、临床疗效、安全性等进行综述。
Most ophthalmic surgeries are characterized by small incisions and mild pain, therein, the choice of topical anesthesia can meet the needs of surgeries and accelerate ophthalmic surgeries to be conducted in day surgery model. 0.4% oxybuprocaine hydrochloride eye drops is one of commonly used topical anesthetics for ophthalmic surgery, which has the characteristics of rapid onset and sufficient analgesia with long duration (about 13 minutes). Oxybuprocaine hydrochloride eye drops has been widely and safely used in intraocular surgery without affecting the pupil and blood vessels. Meanwhile, oxybuprocaine hydrochloride eye drops has negligible effects on corneal thickness and corneal epithelial thickness to meet the needs of refractive surgery. In addition, oxybuprocaine hydrochloride eye drops can provide sufficient postoperative analgesia, reduce the use of postoperative analgesics and the incidence of emergence agitation in children after strabismus surgery. The preservative-free topical anesthetic would be one of ideal topical anesthetics as it can provide a good surgical condition and reduce complications and risks of post-operative infections without changing the onset time and analgesia effects. This article provides a review of the mechanism, analgesia, pharmacokinetics, clinical efficacy, and safety profiles of 0.4% oxybuprocaine hydrochloride eye drops.
青光眼是一组以病理性眼压升高为主要危险因素的,以青光眼性神经萎缩和视野缺损为主要特征的全球首位不可逆性致盲眼病。超声睫状体成形术(UCP)是一种新型非侵入性青光眼治疗技术,其降眼压主要原理为利用高强度聚焦超声破坏睫状突上皮细胞以减少房水生成,并增加葡萄膜巩膜通道的房水流出。UCP适应证广泛,早期主要用于各类难治性青光眼患者,特别是晚期及绝对期患者,研究者发现其除降眼压外,还能够显著缓解该类患者的局部疼痛。近年来,UCP在未经手术治疗的青光眼患者和早、中期青光眼病例中,也表现出了良好的降眼压效果,同时显示出较少的并发症和较轻的术后反应,并可重复治疗。然而不同类型青光眼UCP疗效存在一定差异,且为达最佳治疗效果,其治疗需匹配恰当的探头型号以及适当的治疗扇区。现有较广泛应用于国外的基于眼轴和白到白参数的公式计算方法,测算精度并不适用于国人,然而精准度更高的模型法,其便捷性仍有待进一步提高。UCP虽可减少降眼压药物用量,但术后用药策略的调整仍可能导致眼压波动。综上,针对UCP手术的适应证选择、手术参数设计、疗效预判以及术后管理策略等,仍有待开展相关临床研究,以期为其临床应用提供更加可靠的依据。

Objectives: To evaluate the clinical value of peripheral retinal diseases in myopic patients examined by 200-degree ultra-wide field laser ophthalmoscope (Daytona). Methods: This was a prospective case-control study. We collected 1 000 myopic patients (2 000 eyes) who were scheduled to undergo refractive surgery in Aier Eye Hospital. They were examined by 200-degree ultra-wide field laser ophthalmoscope (Daytona) with non-mydriasis and three-mirror contact lens with mydriasis. The examination results were recorded and statistically analyzed. Results: A total of 230 cases (310 eyes) with peripheral retinopathy were found by 200-degree ultra-wide field laser ophthalmoscope (Daytona). The positive rate was 15.50%; 242 cases (322 eyes) with peripheral retinopathy were found by three- mirror contact lens, and the positive rate was 16.10%. The two methods were consistent in the detection of peripheral Retinopathy in myopic patients (the Kappa value is between 0.8 and 1.0). Conclusion: 200-degree ultra-wide field laser ophthalmoscope (Daytona) is an effective and rapid method for detecting peripheral retinopathy. It provides a broad clinical application prospects for peripheral retinopathy screening before refractive surgery.

Patients with low vision are severely impaired in visual function due to different ocular and neurological disorders,which have a serious impact on their daily activities (such as reading and driving), quality of life and mental health.People's perception of external information mainly comes from vision. Expect for the life-threatening major diseases,visual damage has the greatest impact on people's senses. With the ageing of the population, the problem is getting worse, and low vision has become a serious public health problem in the world. Currently the development of low vision rehabilitation is facing a huge challenge in clinical and scientific research, to develop a visual impairment assistance technology that can effectively improve visual function while balancing multiple functions. It requires the joint development and cooperation of multiple disciplines such as medicine, biology, engineering, microelectronics, and computer science. Low vision rehabilitation provides patients with appropriate visual impairment assistance technology,maximizing the use of residual vision and visual function of patients, improving the functional limitations associated with low vision, effectively improving their independence and overall quality of life, and makes it possible for them to live, work and integrate into the society independently. This article reviews the progress in the application on visual impaired assistive technologies such as classic visual aids, artificial vision (visual prostheses/visual sensory replacement devices), transcranial stimulation and visual biofeedback training in low vision rehabilitation.

Objective: To investigate the practical effect of the integrated group cooperation model in managing patients with fundus diseases in day surgery. Methods: 582 patients with fundus disease who underwent day surgery from January to June in 2022 were included as the control group, and 633 patients with fundus disease who underwent day surgery from January to June in 2023 were selected as the study group. The control group implemented the overall responsibility nursing system, while the study group carried out the collaborative management model, integrating medical and nursing for the entire process of patient management. Chi-square test and T-test were used to compare the differences of perioperative nursing knowledge, health education awareness, satisfaction, emergency ophthalmological consultation rate within 24 hours of discharge, follow-up rate within 24 hours of discharge, and nurses' sense of professional benefit between the two groups. Results: The awareness of health education in the study group was higher than that in the control group, and there was significant statistically difference between two groups (t=–18.47, P<0.05). The satisfaction of patients in the study group was higher than that in the control group, and there was significant statistically difference between two groups (t=–4.005, P < 0.05). The follow-up rate within 24 hours after discharge was 100% in the study group and 98.1% in the control group, and the difference was statistically significant (χ2=12.073, P<0.05). The incidence of ophthalmic emergencies within 24 hours of discharge in the study group was 0.94%, while in the control group it was 1.89%. There was no statistically significant difference between the two groups (χ2= 1.951, P=0.222). The perceived benefit score of nurses after implementation was higher than that before implementation, and there was statistically significant between two groups (t=–6.637, P<0.05). Conclusions: The medical and nursing integrated group cooperation management model is used to manage the entire perioperative process of patients undergoing day surgery in fundus surgery. This model can improve patients' medical experience, enhance their compliance with ophthalmic surgery, ensure their safety. At the same time, it can enhance the senses of professional benefits for nurses.
