近年来，眼部电流刺激(electrical stimulation,ES)在不同方向的研究中逐渐揭示了其在多种视网膜疾病中的潜在治疗价值。其中，经角膜电刺激(transcorneal electrical stimulation,TES)作为一种非侵入性的治疗方法，能对视网膜、视神经、眼底血管及其相关结构产生积极的影响。TES能够改善视力，在保护感光细胞和减缓疾病进展方面显示出积极效果，提高患者的生存质量，还能够在不损伤眼球的情况下调节大脑中的神经元活动，为视网膜疾病的治疗提供一种新的选择。该文对近年来TES在视网膜色素变性(retinitis pigmentosa,RP)、年龄相关性黄斑变性(age-related macular degeneration,AMD)、视网膜血管病、青光眼以及视神经病变等疾病中的应用研究进行了综述。研究发现，TES治疗是一种安全且无需手术的辅助治疗工具，具有广泛的应用前景。该文旨在为临床医师提供一个全面的TES研究概述，并深入探讨其在眼科学领域的潜在应用价值。然而，TES治疗的具体机制仍需进一步探讨，以便更好地应用于临床实践。同时，未来研究还应关注TES与其他治疗方法相结合的效果，以期为患者提供更多有效的治疗选择。

In recent years, electrical stimulation of the eye (ES) has gradually revealed its potential therapeutic value in a variety of retinal diseasesin different directions. Among them, transcorneal electrical stimulation (TES), as a non-invasive treatment, can have a positive effect on the retina, optic nerve, fundus vessels and related structures. TES can improve vision, show positive effects in protecting photoreceptor cells and slowing disease progression, improve the quality of life of patients, and can regulate neuronal activity in the brain without damaging the eyeball, providing a new option for the treatment of retinal diseases. The research on the application on TES on retinitis pigementosa (RP), age-related macular degeneration (AMD), retinal angiopathy, glaucoma and optic neuropathy are reviewed in this article. It is found in the study that TES therapy is a safe and surgery-free adjuvant therapy tool, and has a wide application prospect. The purpose of this article is to provide clinicians with a comprehensive overview of TES research,and to explore its potential application value in the field of ophthalmology. However, the specific mechanism of TES therapy still needs to be further explored in order to better apply in clinical practice. At the same time, future studies should also focus on the effect of combining TES with other treatment methods, in order to provide more effective treatment options for patients.

糖尿病视网膜病变是糖尿病引起的微血管病变之一，是不可逆性致盲的眼病。根据其病程可分为根据其病程可分为非增殖期和增殖期，其中还包括糖尿病性黄斑水肿。全科医师需要检测量裸眼视力、矫正视力和眼压，通过裂隙灯显微镜评估眼前节以及眼底检查来评估眼部整体情况。控制血糖、血压、血脂对改善预后很重要。需要重视餐前、餐后血糖，糖化血红蛋白和代谢记忆，一线降血压药物包括血管紧张素转化酶抑制剂和血管紧张素Ⅱ受体阻断剂，调脂药物首选他汀类，而非诺贝特有额外的视网膜保护作用。干预生活方式，宣教，早期发现也同样重要。全科医师需要进行眼底筛查和评分，及时转诊至眼科治疗。眼科治疗包括全视网膜激光光凝术、经平坦部玻璃体切除术、玻璃体抗血管内皮生长因子药物注射术。

Diabetic retinopathy is one of the microvascular diseases caused by diabetes, it is an irreversible blindness eye disease. According to its course, it can be divided into non-proliferative diabetic retinopathy and proliferative diabetic retinopathy, including diabetic macular edema. Te general practitioner needs to measure the uncorrected visual acuity, corrected visual acuity intraocular pressure, use the slit lamp microscope to exam the anterior segment and fundus to evaluate the overall condition of the eye. Controlling blood glucose, blood pressure and blood lipid is very important to improve the prognosis. Attach importance to pre- and postprandial blood glucose, glycosylated hemoglobin and metabolic memory should be carried out. The first-line antihypertensive drugs are angiotensin converting enzyme inhibitors and angiotensin II receptor blockers. Statins are the first choice for lipid-lowering drugs, fenofibrate has additional protective efect of retinal. Intervention in lifestyle, education and early detection are is important. Te general practitioner needs to perform fundus screening and scoring, timely refer to ophthalmology department for treatment. Ophthalmic treatment includes panretinal laser photocoagulation, pars plana vitrectomy, and intravitreal injection of anti-vascular endothelial growth factor drugs.

慢性中心性浆液性脉络膜视网膜病变(cCSC)以广泛的脉络膜视网膜异常为特征，包括脉络膜血管扩张及其引发的弥漫性视网膜色素上皮病变和浆液性视网膜脱离，常累及黄斑区，引起视功能损害。传统观点认为其可能由急性CSC演变而来，但近期研究显示两者在临床上存在明显差异。其病情反复、迁延，预后较差。随着光学相干断层扫描血管造影(OCTA)、超广角成像和en face重建成像等新多模式影像(MMI)技术的出现和人工智能及机器学习的发展，更多有意义的cCSC影像学特征不断出现。文章详细介绍了cCSC在眼底成像、眼底自发荧光(FAF)、光学相干断层扫描(OCT)、眼底荧光素血管造影(FFA)、吲哚菁绿血管造影和OCTA等影像技术中的表现，并探讨了人工智能在识别CSC分类及其OCT 生物标志物等方面的应用。不同影像技术在cCSC的诊断和研究中各有优势，如FAF可能是评估疾病进展及变化的有效手段，OCT可更直观地观察视网膜结构的改变，FFA是识别渗漏点的重要检查手段，而OCTA可能是评估脉络膜微循环的的最佳手段等。这些MMI研究进展为深入了解cCSC的病理生理机制及临床特征提供了重要线索，有助于提高诊断的准确性和效率，改善患者的预后和生活质量。

Chronic central serous chorioretinopathy (cCSC) is characterized by extensive retinochoroidal abnormalities. This includes difuse retinal pigment epitheliopathy and serous retinal detachment associated with choroidal vasodilatation, ofen involving the macula and cause visual impairment. It was originally considered that it might evolve from acute CSC, but recent studies have shown significant clinical differences between the two. It tends to recur, be prolonged, and have an unfavorable prognosis. With the advent of new multimodal imaging (MMI) techniques such as optical coherence tomography angiography (OCTA), ultra-wide-feld imaging, and en face reconstruction imaging, along with the advancement of artificial intelligence and machine learning, more significant cCSC imaging characteristics have been constantly emerging. Tis article provides a comprehensive overview of cCSC’s imaging features across various modalities, including fundus photography, fundus autofluorescence (FAF), optical coherence tomography (OCT), fuorescein angiography (FFA), indocyanine green angiography, and OCTA. It also explores the application of artifcial intelligence in identifying CSC classifications and OCT biomarkers. Different imaging techniques have their own advantages in the diagnosis and study of cCSC, such as FAF being an efective means to assess disease progression and changes, OCT providing a more intuitive observation of retinal structural changes, FFA being an important tool for identifying leakage points, and OCTA possibly being the best means to assess choroidal microcirculation. Tese MMI research advancements ofer crucial insights for clinicians, aiding in more accurate diagnosis and efective treatment, thereby potentially improving patient outcomes and quality of life.

巨噬细胞样细胞(macrophage-like cells, MLC)指起源、功能与巨噬细胞类似的免疫细胞，包括小胶质细胞、玻璃体细胞及巨噬细胞。将en face OCT显示层面设置在视网膜表明即可观测到视网膜表明的 MLC(epiretinal MLC, eMLC)，随后利用ImageJ软件即可对细胞进行提取和量化。研究表明，eMLC在炎症情况下均可出现细胞募集及活化现象，但在不同眼底病中各具特点。在糖尿病视网膜病变、视网膜静脉阻塞等视网膜缺血缺氧性疾病中，eMLC密度越高，黄斑水肿可能越严重。此外，eMLC密度更高的视网膜静脉阻塞患者抗VEGF疗效更差，视力预后不佳，提示基于en face OCT的eMLC不仅可用于评估视网膜炎情况，而且还能充当提示疾病疗效及预后的标志物。在葡萄膜炎等免疫炎症性疾病中，en face OCT亦可观测到eMLC密度、形态等改变。白塞病葡萄膜炎患者视网膜血管渗漏程度与eMLC密度相关性强，故eMLC密度可充当无创评估视网膜血管渗漏程度的新指标。然而，目前提取和量化eMLC的方法及标准不统一，降低了各研究间的可比性。因此，亟需制定统一的操作规范和评估标准。此外eMLC 所代表的具体细胞类型及功能仍需进一步探究。未来，研究者可以利用en face OCT对眼底炎症地进行无创评估。基于en face OCT的eMLC还能作为基础研究与临床研究之间的桥梁，为揭示疾病的致病机制提供重要参考。

Macrophage-like cells (MLC) refer to immune cells that originate from and function similarly to macrophages, including microglia, hyalocytes, and macrophages themselves. By setting the display level of en face OCT to the retinal surface, epiretinal MLC (eMLC) can be observed and subsequently extracted and quantified using ImageJ software. Studies indicate that eMLC can exhibit cell recruitment and activation in inflammatory conditions, each displaying distinct characteristics in different retinal diseases. In ischemic and hypoxic retinal conditions such as diabetic retinopathy and retinal vein occlusion, higher densities of eMLC are associated with more severe macularedema. Moreover, patients with retinal vein occlusion showing higher eMLC densities tend to have poorer responses to anti-VEGF treatments and worse visual prognoses, suggesting that eMLC identified via en face OCT can be used not only to assess retinal inflammation but also as biomarkers for disease efficacy and prognosis. In immune-inflammatory diseases like uveitis, changes in eMLC density and morphology can also be observed through en face OCT. Inpatients with Beh?et's disease, a strong correlation exists between the degree of retinal vascular leakage and eMLC density, making eMLC density a potential non-invasive marker for assessing retinal vascular leakage. However, the current methods and standards for extracting and quantifying eMLC are not unified, significantly reducing comparability between studies. Therefore, there is an urgent need to establish uniform operational protocols and assessment standards. Furthermore, the specific cell types and functions represented by eMLC observed via en face OCT require further investigation. In the future, en face OCT could be utilized for non-invasive assessment of retinal inflammation. eMLC based onen face OCT could also serve as a bridge between basic research and clinical studies, providing valuable insights into the pathogenic mechanisms of diseases.

糖尿病视网膜病变(diabetic retinopathy, DR)作为糖尿病的一种常见并发症是导致工作年龄人群失明的主要原因。血糖变异性(glycemic variability, GV)指血糖波动的程度。最新研究表明，GV与糖尿病患者的代谢状况和微血管病变密切相关。该文综述了GV对DR的影响及其研究进展。GV是指血糖水平在高点和低点之间波动的不稳定状态，分为长期GV和短期GV。长期GV主要通过空腹血糖(fasting plasma glucose, FPG)、餐后血糖(postprandial plasma glucose, PPG)和糖化血红蛋白(glycated hemoglobin, HbA1c)评估，短期GV则通过血糖标准差(standard deviation, SD)、变异系数(coefficient of variation, CV)、低血糖指数(low blood glucose index, LBGI)等指标量化。研究表明，GV是糖尿病大管和微血管并发症的重要风险预测因子，与冠状动脉综合征、心肌梗死、脑卒中、糖尿病肾病、周围神经病变等密切相关。在DR方面，GV可能是其进展的风险因素，高GV会加剧氧化应激、炎症反应、内皮功能障碍和新生血管生成，从而促进DR的发展。治疗策略包括动态血糖监测系统、药物干预(如基础胰岛素、阿格列汀等)、合理饮食和运动等，这些方法可改善GV，降低并发症风险，提高患者预后和生活质量。

Diabetic retinopathy (DR) is a common complication of diabetes and is a leading cause of blindness in the working-age population. Glycemic variability (GV) refers to the degree of fluctuation in blood glucose levels. Recent studies have shown that GV is closely related to the metabolic status and microvascular complications in patients with diabetes. This article reviews the impact of glycemic variability (GV) on diabetic retinopathy (DR) and the latest research progress.GV is defined as the unstable state of blood glucose levels fluctuating between highs and lows, which is categorized into long-term GV and short-term GV. Long-term GV is mainly assessed through fasting plasma glucose (FPG), postprandial plasma glucose (PPG), and glycated hemoglobin (HbA1c). Short-term GV is quantified by indicators such as the standard deviation of blood glucose (SD), coefficient of variation (CV), and low blood glucose index (LBGI).Studies have shown that GV is an important risk predictor for both macrovascular and microvascular complications in diabetic patients, being closely associated with conditions such as coronary artery syndrome, myocardial infarction, stroke, diabetic nephropathy, and peripheral neuropathy. Regarding DR, GV is likely a risk factor for its progression. High GV can exacerbate oxidative stress, inflammatory responses, endothelial dysfunction, and neovascularization, thereby promoting the development of DR.Treatment strategies include continuous glucose monitoring systems, pharmacological interventions (such as basal insulin, alogliptin, etc.), as well as proper diet and exercise. These approaches can improve GV, reduce the risk of complications, and enhance patients' prognosis and quality of life.

Objective: To evaluate the imaging characteristics of infrared light reflection (IR) and fundus fluorescein angiography (FFA) in hemorrhagic retinal artery aneurysm and its complications. Methods: Retrospective case series study was used. The clinic data of 35 patients (35 eyes) were diagnosed in Henan Eye Hosptial from February 2010 to June 2024. All eyes were examinated by IR and FFA, and 10 eyes examinated by indocyanine green angiography (ICGA). The fundus imaging characteristics of hemorrhagic retinal artery aneurysm and its complications was analyzed. Results: The images of IR presented 34 eyes with cystic strong reflex light. FFA showed 27 eyes with cystic strong fluorescence, in addition, FFA revealed 5 eyes with retinal branch vein occlusion and 1 eye with retinal branch artery occlusion. The detection rate of hemorrhagic retinal artery aneurysm in the FFA group was lower than that in the IR group (P =0.038<0.05). There was no significant difference in the detection rate of hemorrhagic retinal artery aneurysm between the IR group and the ICGA group in 10 eyes with hemorrhagic retinal artery aneurysm (P =1.000>0.05). Conclusion: IR examination could be equivalent to ICGA examination for detecting hemorrhagic retinal artery aneurysm, and IR combined with FFA examination is suitable for individualized diagnosis of hemorrhagic retinal artery aneurysm and its complications.

Purpose: To investigate the clinical and imaging characteristics of retinal neovascularization of the optic disc (NVD) and/or elsewhere in the retina (retinal neovascularization elsewhere, NVE) in eyes with Behçet's uveitis (BU). Methods: This retrospective analysis reviewed the clinical data and fundus imaging findings of patients diagnosed with BU complicated by NVD and/or NVE from January 2022 to September 2024. Imaging modalities included fundus photography, fluorescein fundus angiography (FFA), optical coherence tomography (OCT), and OCT angiography (OCTA). The study analyzed the correlation between the areas of NVD and/or NVE and the modified posterior segment inflammation scores, as well as retinal vascular leakage scores of the affected eyes. Results: The study included 27 patients (30 eyes) with an average age of (27.70 ± 12.58) years and a gender ratio of approximately 1:1. Bilateral NVD and/or NVE was observed in three patients (11%); 25 eyes (83%) had NVD, of which 17 eyes (57%) had only NVD and 8 eyes (27%) had both NVD and NVE. Two eyes (7%) showed areas of retinal non-perfusion, and seven eyes (23%) had concurrent vitreous hemorrhage. The average score for posterior segment inflammation on FFA was 20.93 ± 4.37, and the average score for vascular leakage was 7.57 ± 1.25. There was a significant positive correlation between the area of NVD and/or NVE and both the inflammation score (r_s = 0.403, P = 0.027) and the vascular leakage score (r_s = 0.518, P = 0.003). FFA and OCTA showed perfect agreement in detecting NVD and NVE (κ = 1.0). Conclusion: NVD and/or NVE in BU are not uncommon and are predominantly presented as NVD, mostly not associated with retinal nonperfusion, likely induced by inflammatory factors related to BU.
