因不同的眼部和神经性疾病，导致视觉功能严重受损，为低视力患者日常活动(如阅读及驾驶)及生活质量、心理健康带来严重的影响。人们对外界信息的感知主要来源于视觉，除威胁生命的重大疾病外，对人感官影响最大的损害当属视觉损伤。且随着人口日益老龄化，该问题日趋加重，低视力已成为目前全球范围内一个严重的公共卫生问题。目前，低视力康复发展面临着临床和科研的巨大挑战，要研发出一种能有效改善视觉功能，同时能兼顾多种功能的视障辅助技术，这需要医学、生物学、工程学、微电子学、计算机学等多学科的共同发展和相互合作。低视力康复通过为患者提供适宜的视障辅助技术，最大化利用患者的残余视力及视觉功能，改善与低视力相关的功能限制，有效改善其独立性和整体生活质量，使其独立生活、工作并融入社会成为可能。该文对经典的助视器、人工视觉(视觉假体/视觉感官替代设备)、经颅刺激及视觉生物反馈训练等视障辅助技术在低视力康复中的应用进展进行综述。
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.
目的：探究T盒转录因子2(T-box transcription factor 2,TBX2)在葡萄膜黑色素瘤(uveal melanoma,UVM)中的表达水平、生存预后、免疫浸润相关性。方法：首先通过TIMER2.0数据库分析正常组织和肿瘤组织中TBX2表达和临床特征，从UCSC Xena数据库下载泛癌的生存数据，使用Cox比例风险模型和Kaplan-Meier曲线分析评估TBX2对预后的预测价值。然后使用cBioPortal数据库分析人源TBX2突变前后生存改变，通过BloodSpot和TIMER2.0数据库探究TBX2与癌症免疫浸润之间的相关性。癌症单细胞状态图谱和基因集变异分析(gene set variation analysis,GSVA)探究其表达与分子机制的相关性。结果： 15种肿瘤类型的TBX2 mRNA表达水平显著改变，TBX2是肾上腺皮质癌(adrenocortical carcinoma,ACC)、肾乳头状细胞癌(kidney renal papillary cell carcinoma,KIRP)、UVM典型的生存预后标志物。其突变与生存状态无明显相关性，在UVM中T淋巴细胞浸润水平提高导致不良预后风险升高。此外，在UVM中TBX2通路富集至ATP结合盒(ATP-binding cassette transporter,ABC)转运蛋白、DNA修复和损伤。结论：TBX2在UVM的生存和免疫浸润中起着关键作用，将来可能作为一种UVM预后及免疫治疗效果的预测因子。
Objective: To investigate the expression level of T-box transcription factor 2(TBX2) in uveal melanoma (UVM), the correlation between survival prognosis and immune infiltration. Methods: The expression and clinical features of TBX2in normal and tumorwere analyzed by TIMER2.0 database. The survival data of pancarcinoma were downloaded from UCSC Xena database, and the prognotic value of TBX2 was evaluated using Cox proportional risk model and Kaplan-Meier curve analysis. Then cBioPortal database was used to analyze the changes before and after TBX2 mutation survivalin human, and BloodSpot and TIMER2.0 databases were used to explore the correlation between TBX2 and cancer immune infiltration. Cancer single cell status mapping and gene set variation analysis (GSVA) were used to explore the correlation between its expression and molecular mechanisms. Results: The mRNA expression levels of TBX2 were significantly changed in 15 tumor types. TBX2 is adrenocortical carcinoma (ACC) and kidney renal papillary cell carcinoma (Kidney renal papillary cell carcinoma). KIRP and UVM are typical prognostic markers of survival. The mutation had no significant correlation with survival status, and increased T cell infiltration level in UVM led to increased risk of poor prognosis. In addition, the TBX2 pathway is enriched to the ATP-binding cassette transporter (ABC) transporters, DNA repair, and damage in UVM. Conclusion: TBX2 plays a key role in survival and immune invasion of uveal melanoma.and may be used as a predictor of UVM prognosis and immunotherapy effect in thefuture.

Objective: To compare the effects and distinctions among three methods of phacoemulsification training: EYESi simulator (Dry-lab), Wet-lab, and a combined approach, in order to find out more scientific and efficient teaching method. Methods: 18 first-year residents undergoing residency training at Zhongshan Ophthalmic Center, Sun Yatsen University were randomly assigned to three groups: Dry-lab, Wet-lab, and Combined. Each group, consisting of 6 individuals, underwent a specific training regimen—8 sessions of effective simulator training for the Dry-lab group, 8 Wet-lab sessions for the Wet-lab group, and a combination of 4 effective simulator sessions with 4 Wet-lab sessions for the Combined group. The questionnaires were administered to assess simulation effects and student satisfaction before and after each training sessions. Additionally, the training effects were recorded in the three main steps of phacoemulsification cataract extraction surgery on a pig eye model. Results: Both the EYESi simulator and Wet-lab were proved to be effective in facilitating the learning of microscopic instrument use with commendable operating experience. However, Wet-lab is superior to the virtual simulator in terms of stereoscopic sensation (P=0.007), similarity to the human eye (P<0.001), and assistance in mastering techniques(P=0.003). Simulator training is found to be more advantageous in shortening the overall training time (P<0.001). The training effect of the joint training mode is better than that of single Wet-lab training (P=0.014) and simulator training (P=0.012), and the overall satisfaction is higher than that of Wet-lab training (P=0.042) and simulator training (P=0.042). Conclusion: The EYESi virtual surgery simulator and Wet-lab training have their advantages respectively in training for phacoemulsification cataract extraction microsurgery, and the combined teaching mode is more efficient, with better training effects and overall satisfaction.
目的：旨在研究按移植指征分类以及移植前角膜血管形成对手术后5年内排斥反应和移植物失败率的相对风险。方法：分析1999—2017年间，英国移植登记处记录的所有因圆锥角膜(keratoconus,KC)、人工晶状体大泡性角膜病(pseudophakic bullous keratopathy,PBK)或既往感染(病毒/细菌/真菌/原生动物)而首次进行角膜移植的成年人。统计移植前受体角膜血管化象限的数量、血管化类型、移植后排斥反应的间隔时间(如果有的话)以及移植后5年的结果。通过多变量风险调整Cox回归法进行排斥反应和移植失败的危险因素建模。结果：KC、PBK和感染患者的角膜血管形成率分别为10%、25%和67%。只有当存在浅表和(或)深部血管形成时(HR分别为1.3和1.4，P=0.004)，存在两个以上象限的血管形成时，PBK患者移植排斥反应的风险才会增加(HR=1.5，P=0.0004)。因既往感染而接受移植的个体在四个象限的血管形成中发生排斥反应的风险增加(HR=1.6，P=0.003)。在任何一组中，经过风险调整后，与血管形成有关的移植失败率并未上升。对于含有血管的受体角膜，相对于穿透性KC和PBK移植，没有充分的证据显示板层移植在降低排斥反应或失败风险方面存在优势。结论：血管化是5年内角膜移植排斥反应的危险因素。移植的适应证对这种风险的具有临床意义。
Objective: To investigate the relative risk of pretransplant corneal vascularisation on rate of rejection and graft failure within 5 years of surgery when categorised by indication for transplantation. Methods: We analysed all adults recorded in the UK transplant registry who had a first cornea transplant for keratoconus (KC), pseudophakic bullous keratopathy (PBK) or previous infection (viral/bacterial/fungal/protozoan) between 1999 and 2017. We analysed the number of quadrants of the recipient cornea vascularised before transplant and type of vascularisation, the interval posttransplant to rejection, if any, and the outcome at 5 years post-transplant. Risk factors for rejection and transplant failure were modelled by multivariable risk-adjusted Cox regression. Results: Corneal vascularisation was recorded in 10%, 25% and 67% of patients with KC, PBK and infection, respectively. Individuals with PBK had an increased hazard of transplant rejection only when there were more than two quadrants of vascularisation (HR 1.5, p=0.004) when either superficial and/or deep vascularisation was present (HR 1.3 and 1.4, respectively, p=0.004). Individuals who had a transplant for previous infection had an increased hazard of rejection with four quadrants of vascularisation (HR 1.6, p=0.003). There was no risk-adjusted increase in transplant failure associated with vascularisation in any group. There was weak evidence of reduction in risk of rejection and/or failure associated with lamellar compared with penetrating transplantation in KC and PBK in vascularised recipient corneas. Conclusion: Vascularisation is a risk factor for corneal allograft rejection within 5 years. The indication for transplantation has a clinically significant effect on the magnitude of this risk.

Objective: To assess the efficacy and safety of phakic refractive lens (PRL) implantation for the correction of ultra-high myopia. Methods: This self-controlled case series study included 39 eyes of 24 patients with ultra-high myopia who underwent PRL implantation at Shenzhen Eye Hospital between January 2018 and September 2020. The study comprised 13 eyes in 8 males and 26 eyes in 16 females, with a mean age of (31.15 ± 6.33) years. Postoperative parameters, including refraction, visual acuity (UCVA, BCVA), intraocular pressure, corneal endothelial cell count,vault, and surgical complication were observed. Results: The median follow-up time was 5.5 (3, 11) months. The refraction significantly decreased from preoperative (-22.29±4.96) D to postoperative (-0.28±1.01) D (t=24.421, P<0.001). Postoperatively, 82.4% of eyes achieved a spherical degree within ±0.5 D, and 91.2% within ±1.0 D. LogMAR UCVA significantly improved from 1.40 (1.30, 1.70) preoperatively to (0.28±0.20) postoperatively. LogMAR BCVA significantly improved from 0.40 (0.22, 0.70) preoperatively to 0.15 (0.00, 0.30) postoperatively (P<0.001 for all). Postoperative BCVA improved by 3.00 (1.00, 5.00) lines compared with preoperative BCVA, with no instances of BCVA loss in any patient. Intraocular pressure values showed significant differences among preoperative, 1 day postoperative and last follow up (F=8.779, P=0.012). Intraocular pressure increased significantly 1 day after surgery compared to before surgery (Z=-3.401, P=0.001), but decreased significantly at the last follow-up compared to 1 day postoperatively(Z=-2.685, P=0.007), with no significant difference in intraocular pressure between preoperative and last follow-up (Z=-0.894, P=0.371). Corneal endothelial cell count decreased significantly from preoperative (2 782.20±296.30)/mm2 to postoperative (2 472.54±394.32)/mm2 (t=?5.437, P<0.001), with a mean loss of 11.2%. The average vault at the last follow-up was (379.00±283.27) μm, of which 0~250 μm in 12 eyes (36.4%), 250~750 μm in 19 eyes (57.6%), and > 750 μm in 2 eyes (6%). In 21 eyes, the vault at 3 months postoperative (269.81±194.67) μm was significantly lower than that at 1 month postoperative (373.62±195.75) μm (t=?2.917, P=0.009). Postoperative complications included steroid-induced glaucoma (2 eyes in 1 case), PRL optical surface crack (1 eye), macular hemorrhage (1 eye), and PRL decentration (3 eyes in 2 cases). Conclusions: PRL implantation is a safe and effective intraocular refractive surgery for ultra-high myopic patients. Nonetheless, it should be neccessary to observe for long-term efficacy and saff lens; high myopia

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.
