准分子激光原位角膜磨镶术(laser-assisted in situ keratomileusis,LASIK)是矫正屈光不正的重要角膜屈光手术方式之一。经过准分子激光切削的角膜，生物测量数据发生改变。对于此类患者，通过常规测量获得的参数数据以及使用常规计算公式确定的IOL屈光度将变得不再准确，由此将会导致术后较大的屈光误差，进而影响患者的视觉质量。本文报道一例46岁的男性白内障患者。该患者既往双眼屈光不正，曾接受过LASIK手术治疗。白内障术前角膜地形图检查发现该患者双眼存在角膜偏心切削，这为IOL屈光度的确定带来困难。手术医生通过角膜地形图判断角膜切削的居中性，在特定区域内选择角膜曲率K值，并采用Barrett True K公式计算出IOL屈光度。白内障术后患眼屈光误差相对较小，视力提高，视觉质量改善。
Laser-assisted in situ keratomileusis (LASIK) is a crucial corneal refractive surgery for correcting refractive errors. The cornea, after undergoing excimer laser ablation, undergoes changes in biometric measurements. For such patients, conventional measurements and IOL power calculations based on standard formulas may no longer be accurate, leading to significant postoperative refractive errors and subsequently impacting the patient's visual quality. This article presents a case of a 46-year-old male cataract patient who had a history of refractive errors in both eyes and had previously undergone LASIK surgery. Preoperative corneal topography revealed corneal eccentric ablation in both eyes, posing challenges in determining IOL power. The surgeon assessed the centration of corneal ablation using corneal topography, selected the keratometry value (K value) within specific corneal regions, and calculated the IOL power using the Barrett True K formula. Postoperatively, the cataract patient experienced relatively minor refractive errors, leading to improved vision and enhanced visual quality.
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.

Objective: To establish and validate a universal artificial intelligence (AI) platform for collaborative management of cataracts involving multilevel clinical scenarios and explored an AI-based medical referral pattern to improve collaborative efficiency and resource coverage. Methods: The training and validation datasets were derived from the Chinese Medical Alliance for Artificial Intelligence, covering multilevel healthcare facilities and capture modes. The datasets were labelled using a three step strategy: (1)capture mode recognition; (2) cataract diagnosis as a normal lens, cataract or a postoperative eye and (3) detection of referable cataracts with respect to aetiology and severity. Moreover, we integrated the cataract AI agent with a real-world multilevel referral pattern involving self-monitoring at home, primary healthcare and specialised hospital services. Results: The universal AI platform and multilevel collaborative pattern showed robust diagnostic performance in three-step tasks: (1) capture mode recognition (area under the curve (AUC) 99.28%–99.71%), (2) cataract diagnosis (normal lens, cataract or postoperative eye with AUCs of 99.82%, 99.96% and 99.93% for mydriatic-slit lamp mode and AUCs >99% for other capture modes) and (3)detection of referable cataracts (AUCs >91% in all tests). In the real-world tertiary referral pattern, the agent suggested 30.3% of people be ’referred’, substantially increasing the ophthalmologist-to-population service ratio by 10.2-fold compared with the traditional pattern. Conclusions: The universal AI platform and multilevel collaborative pattern showed robust diagnostic performance and effective service for cataracts. The context of our AI-based medical referral pattern will be extended to other common disease conditions and resource-intensive situations.

房角镜辅助的内路360°小梁切开术(Gonioscopy-Assisted Transluminal Trabeculotomy,GATT)是近年来国内外开展的新型微创青光眼手术，是一种改良的小梁切开术。GATT将微导管(iTrack)环穿Schlemm's管后，利用微导管张力全周切开小梁网及Schlemm's管内壁，重建生理性房水流出通道，避免小梁网阻力，实现房水从前房直接进入集液管，通过增加房水流出机制降低眼压。GATT适应证广泛，主要应用于开角型青光眼，包括原发型开角型青光眼和继发性开角型青光眼，同时可运用于闭角型青光眼。GATT微创、不依赖滤过泡、能明显减少降眼压药物的使用、中远期疗效稳定、安全性高、较少发生威胁视力的并发症，可作为开角型青光眼的首选手术方式。本文将对GATT在青光眼中的应用、手术步骤、作用机制、有效性、并发症及影响疗效的因素等进行综述，以期为其临床运用提供参考。
As a modifed trabeculotomy, Gonioscopy-Assisted Transluminal Trabeculotomy (GAT) is a new type of minimally invasive glaucoma surgery developed at home and abroad in recent years. GAT inserts a microcatheter (iTrack) into the Schlemm's canal and advance the catheter through the canal circumferentially 360°, then circumferentially fracture the trabecular meshwork and inner wall of Schlemm’s canal. Tis method can reduce intraocular pressure by increasing the outfow of aqueous humor. Te physiological outfow pathway of aqueous humor is reconstructed, which can avoid the resistance of trabecular meshwork and realizing the direct entry of the aqueous humor directly into the collector channel from the anterior chamber. With a wide range of indications, GAT is mainly used in open-angle glaucoma, including primary open-angle glaucoma and secondary open-angle glaucoma, and is also used in primary closed- angle glaucoma. Additionally, GATT can be the preferred surgical modality for open-angle glaucoma, as it has the following advantages: minimally invasive, independent of fltration bleb, can signifcantly reduce the use of medications, stable medium- and long-term efcacy, high safety, and has fewer sight-threatening complications. In order to provide a reference for clinical application, this article reviews the indications, mechanism of action, surgical procedures, efectiveness, complication and factors afecting therapeutic efect.
报告一例视神经脊髓炎谱系疾病(neuromyelitis optica spectrum disorders,NMOSD)合并人体免疫缺陷病毒(human immunodeficiency virus,HIV)感染/获得性免疫缺陷综合征(acquired immune deficiency syndrome,AIDS)，并通过文献复习，总结其发病机制、临床特征、治疗及预后。检索文献包括7篇英文文献(8个病例)，1篇中文文献，共报道9例NMOSD合并HIV感染/AIDS病例，结合本文报道的1例共10例，其中5例为女性，5例为男性，3例HIV感染/AIDS为新发，其他病例的HIV感染/AIDS发病均早于NMOSD。临床表现上，7例均为视神经炎和脊髓炎同时或相继发生，2例表现为单相病程或复发性脊髓炎，1例仅表现为双眼相继发生的视神经炎，10例患者头或脊髓MRI均有典型的视神经或脊髓异常信号，伴或不伴强化。2例患者未进行水通道蛋白4(aquaporin protein-4,AQP4)抗体IgG检测，其余8例中5例AQP4抗体阳性、3例阴性。针对AIDS的治疗，10例患者中，8例接受了高效抗逆转录病毒治疗(highly active antiretroviral therapy,HAART)。针对NMOSD的治疗，10例患者中，急性期有8例患者接受糖皮质激素冲击治疗、3例患者接受血浆置换、2例接受丙种球蛋白治疗，序贯治疗期有6例患者接受免疫抑制剂治疗，其中1例因高胆红素血症停药。发生视神经炎的7例中，2例患者经治疗仍失明、5例视力部分恢复，发生脊髓炎的8例中，5例患者遗留截瘫或轻瘫、3例肌力部分恢复。1例因严重并发症去世。NMOSD合并HIV感染/AIDS临床较罕见，预后差，往往遗留严重的视力障碍及瘫痪等，临床治疗较为棘手，糖皮质激素和免疫抑制剂并非使用禁忌证，但制定治疗决策前需要充分考虑风险与获益的平衡。
A case of neuromyelitis optica spectrum disorders(NMOSD) complicated with human immunodeficiency virus(HIV) infection/acquired immunodeficiency syndrome(AIDS) was reported, and the pathogenesis, clinical characteristics, treatment and prognosis were summarized through the literature review. The retrieved literatures included seven English literatures (eight cases) and one Chinese literature, in which a total of nine cases of NMOSD co-infected with HIV infection/AIDS were reported. Combined with the case reported in this paper, the total number of cases was ten, among which five cases were female and five cases were male, three cases of HIV infection/AIDS were newly developed, and the other cases had earlier onset of HIV infection/AIDS than NMOSD. In terms of clinical manifestations, seven cases all had simultaneous or sequential optic nerve and myelitis, two patients presented with a uniphasic course or recurrent myelitis, and one case presented only with bilateral optic neuritis occurring sequentially in both eyes. All ten patients had typical abnormal signals of the optic nerve or spinal cord with or without enhancement on cranial or spinal MRI. Two patients did not undergo AQP4 antibody IgG testing , and of the remaining seven cases, five were positive for AQP4 antibodies and three were negative. For AIDS treatment, eight of the ten patients received highly active antiretroviral therapy(HAART). For NMOSD treatment, among the ten patients, eight patients received intravenous methylprednisolone,three patients received plasmapheresis, and two patients received intravenous immunoglobulin in the acute phase. Six patients received immunosuppressive therapy during the sequential treatment period, and one of them was discontinued due to hyperbilirubinemia. Of the seven cases with optic neuritis, two patients remained blind after treatment and five had partial recovery of vision. Of the eight cases with myelitis, five patients were left with paraplegia or mild paralysis, and three had partial recovery of muscle strength. One case died due to serious complications.NMOSD combined with HIV infection/AIDS is rare in clinic and has a poor prognosis. Patients are often left with severe visual impairment and paralysis. Clinical treatment is quite difficult, hormones and immunosuppressive agents are not considered as contraindications. Treatment decisions need to be made with fully considered about the balance of risks and benefits.
