光学相干断层成像(optical coherence tomography，OCT)自1991年发明以来，在生物成像尤其在眼科和心血流成像中起越来越重要的作用。OCT的发展经历了早期的时域系统及最新的频域系统。其中频域系统又分为谱域OCT(spectral domain OCT，SD-OCT)系统和扫频OCT(swept source OCT，SS-OCT)系统。随着眼科临床应用对系统速度、灵敏度及功能化要求的不断提升，眼科扫频OCT已经走向成熟并逐步商用化。本文将简介扫频OCT的原理，并归纳扫频OCT相对于时域和谱域OCT系统的优势，并展示其在眼科临床的应用。

Optical coherence tomography (OCT) has played an important role in biomedical imaging, especially in ocular and cardiovascular imaging. OCT technology has evolved to frequency domain technology from early time-domain technology due to the advantages of high sensitivity and high speed of frequency domain techniques. The swept source OCT is a type of frequency domain OCT. With the increasing requirements for system speed, sensitivity, and functionality in clinical application, swept source OCT is gradually becoming commercially available and widespread in clinical application. In this paper, the principle of swept source OCT was introduced, the advantages of swept source OCT over time domain and spectral domain OCT systems were summarized, and its clinical application in ophthalmology was demonstrated.

目的：探讨人工晶状体(IOL)预先巩膜悬吊在严重晶状体半脱位中的应用效果。方法：选取 2018年12月至2022年7月四川省人民医院收治的>180°的严重晶状体半脱位患者8例(8 眼)。术中避开脱位的晶状体，预先将IOL悬吊于玻璃体腔，再将晶状体托起置于IOL上方，必要时辅助以虹膜拉钩，稳定晶状体，确保超声乳化手术安全完成。结果：严重的晶状体半脱位患者8例，其中晶状体核N1-N3硬度的患者各1例，单独使用IOL预先巩膜悬吊于术中稳定脱位的晶状体，3例超声乳化手术均顺利完成；达N4患者3例、N5患者2例，其中4例在虹膜拉钩的辅助下安全完成超声乳化；有1例N5的患者，由于悬韧带损伤超过270°，在将晶状体托起放置于IOL之上时，坠入玻璃体腔，给予玻璃体腔超声粉碎处理。8例患者术后IOL均居中，视力有不同程度的提高，眼压正常，未见严重并发症。结论：在严重晶状体半脱位的超声乳化手术中，对于N2~N3的软核，IOL预先巩膜悬吊可以良好地稳定晶状体，确保超声乳化手术的顺利进行；对于N4~N5的硬核，IOL预先巩膜悬吊可以作为一种辅助方法，联合虹膜拉钩共同稳定晶状体，确保超声乳化手术的安全进行。

Objective: To investigate the effect of intraocular lens (IOL) pre-suspension in thetreatment of severe lens subluxation. Methods: Retrospective case study. From December 2018 to July 2022, 8 eyes of 8 patients with severe lens subluxation greater than 180 degrees admitted to our hospital were selected. During surgery, the IOL should avoid the subluxated lens and be pre-suspended in the vitreous cavity, and then the lens is lifted and placed above the IOL. If necessary, the iris hook can be used to stabilize the lens to ensure the safe completion of phacoemulsification. Results: There were 8 patients with severe subluxation of lens. Among them, the hardness of 3 patients' lens nucleus ranged from N1 to N3. In these 3 patients, we used the IOL pre-suspension alone to stabilize the subluxated lens, and phacoemulsification in these 3 patients was successfully completed. Three patients had N4 and 2 patients had N5, of which 4 patients underwent phacoemulsification safely with the assistance of iris hook. In another patient with N5, the lens fell into the vitreous cavity during surgery (the suspension ligament rapture greater than 270 degrees) when it was lifted and placed on the IOL which was crushed by the vitreous cavity ultrasound. After surgery, the IOL was centered in all 8 patients, visual acuity was improved to varying degrees, intraocular pressure was normal, and no serious complications were observed. Conclusions: In severe lens subluxation surgery, IOL presuspension in soft nuclei of N2 to N3 can stabilize the lens well and ensure the safety of phacoemulsification. For hard nuclei N4 to N5, IOL presuspension can be used as an auxiliary method in combination with iris hook to stabilize the lens and ensure the safety of phacoemulsification.

近年来随着人口老龄化的发展、人群用眼方式的改变，现有的眼科医疗资源正越来越难以满足日渐增长的医疗需求，亟需新型的诊疗模式予以补足。眼科人工智能作为眼科领域的新兴元素，在眼病的筛查诊断中发展迅速，主要表现为“眼部图像数据+人工智能”的模式。近年来，随着该模式在白内障、青光眼、糖尿病性视网膜病变(diabetic retinopathy，DR)等常见病中研究的深入，相关技术日渐成熟，表现出了较大的应用优势与应用前景，部分技术甚至成功转化并被逐渐应用于临床。眼科诊疗向智慧医学模式的过渡，有望缓解日益增长的医疗需求与紧缺的医疗资源之间的矛盾，从而提高整体的医疗服务水平。

The development of population aging and changes in the way people use their eyes over the recent years have increasingly challenged the existing ophthalmic medical resources to meet the growing medical needs, thus urgently calling for a novel diagnostic and treatment mode. Despite its status as an emerging sector in ophthalmology, ophthalmic artificial intelligence has developed rapidly in the screening and diagnosis of eye diseases, as can be seen in practices adopting the “eye imaging data + AI” mode. In recent years, with the intensified research on this mode with respect to common diseases such as cataract, glaucoma and diabetic retinopathy, relevant technologies have grown increasingly mature, presenting undeniable application superiority and prospects. Some of the relevant technical achievements have also been successfully transformed for practical usage, and are gradually being applied to clinical practices. Ophthalmic diagnosis and treatment are transitioning toward the era of intelligent medical services, which are expected to reduce the contradictions between the growing medical needs and the shortage of medical resources, as well as ultimately improve the overall experience of medical services.

Objective: To demonstrate the clinical characteristics and surgical effects of glaucoma in Hallermann-Streiff syndrome(HSS). Methods: Observational case series and literature review. The results of ophthalmic examinations of three patients diagnosed as glaucoma with HSS were recorded, including visual acuity, intraocular pressure (IOP), slit-lamp microscopy, ultrasound biomicroscopy, optical coherence tomography, corneal topography, A-scan and B-scan ultrasonography, and orbital size measurement by X-ray. Peripheral iridectomy, glaucoma drainage device implantation or trabeculectomy, were performed in these patients. Results: Three HSS patients were 9, 29 and 47 years old, respectively, including 2 females and 1 male. The best corrected visual acuity was 0.04-0.5. The mean spherical equivalent refraction was +12.1 D. The average IOP was 37.7 mm Hg, and the average corneal diameter was 9.1 mm. The average central anterior chamber depth was 2.43mm. The average axial length was 18.13mm. Keratometry showed average K1 of 56.97 degrees, and K2 of 60.65 degrees. Two younger patients were aphakic bilaterally with uveitis, pupillary fibrous membrane and peripapillary choroidal atrophy. The older patient showed blue sclera, cataract, and anterior chamber angle closure. The horizontal orbital diameter was 28.76-31.40 mm, and vertical orbital diameter was 30.16-32.90 mm. All patients were proportionate nanism, with an average height of 143 cm. Craniofacial manifestations included dyscephalia and “bird-like” face, hypotrichosis, dental anomalies, and mandibular hypoplasia. They were followed up for an average of 47.7 months(range:11-84 months) after surgery. The IOPs were all controlled, and the visual acuities remained unchanged. No treatment-related complications occurred. Conclusions: HSS patients with glaucoma may present as small orbit, microphthalmia, microcornea, blue sclera, aphakia, pupillary fibrous membrane, uveitis, with atrophic chorioretinal changes. For these patients, personalized treatment may help to achieve better therapeutic effects.

The training of qualified ophthalmologists holds paramount significance in preventing blindness, treating eye diseases, and delivering optimal eye health services to the people. Given the unique nature of standardized residency training across geographical regions, this study delves into the comparative analysis of ophthalmology residency standardized training systems in the Mainland and Hong Kong. Specifically, we examine the the similarities and disparities in multiple facets, encompassing trainees' profiles, faculty expertise, rotation phases and prerequisites, as well as assessment methodologies. Notably, the training system in Hong Kong has a duration of 6 years, approximating the combined length of standardized residency training and standardized specialist training. By comparing the differences, we aim to facilitate the refinement of ophthalmology residency education and training in Mainland China, tailored to our specific context, while also serving as a reference for advancing standardized ophthalmology specialist training initiatives.

息肉状脉络膜血管病变(polypoidal choroidal vasculopathy,PCV)是亚洲人群中常见的致盲性眼病，发生大出血并发症后严重危害视力且预后差。PCV大出血包括视网膜下出血(subretinal hemorrhage,SRH)和玻璃体积血(vitreous hemorrhage,VH)。SRH的危险因素包括较长病程、簇型PCV、息肉状病灶不消退、合并视网膜色素上皮脱离；其治疗方式包括抗血管内皮生长因子药物、光动力疗法、激光、玻璃体腔注气、眼内注射组织纤溶酶原激活剂、玻璃体切割术或联合治疗等方式，其中，黄斑中心凹是否受累和出血时间是影响治疗方式选择的主要因素。发病年龄较大、白细胞计数较高、天门氨酸转移酶和丙氨酸转氨酶的比值较高、活化部分凝血活酶时间较长、曾行光动力疗法、有玻璃体腔注药治疗史、SRH面积大、出现视网膜色素上皮脱离的PCV患者发生VH的风险高。浓厚的VH通常需行玻璃体切割术，其手术时机和手术方式的选择是临床关注的焦点。鉴于目前PCV大出血的危险因素尚不完全明确、治疗方面也尚未形成共识，需要开展相关临床研究，提供更多依据。

Polypoidal choroidal vasculopathy (PCV) is a common blinding disease in Asian populations. Massive hemorrhage complications secondary to PCV include subretinal hemorrhage (SRH) and vitreous hemorrhage (VH). The risk factors for SRH include a long duration, clustered PCV, non-regression of polyp lesions and presented with retinal pigment epithelial detachment. The treatments for SRH include anti-vascular endothelial growth factor drugs, photodynamic therapy, laser, vitreous pneumatic displacement, intravenously injected tissue plasminogen activator, vitrectomy and combination therapy. Whether macular fovea is involved and the time since bleeding onset are the main factors afecting the choice of treatment for SRH. Older age of onset, higher white blood cell count, higher aspartate amino transferase and alanine amino transferase ratio, longer activated partial thromboplastin time retinal pigment epithelium detachment, photodynamic therapy history, intravitreal injection history larger SRH area and presented with retinal pigment epithelial detachment were associated with higher risk of VH. PCV patients with massive VH should be treated with vitrectomy, while the timing and technique of operation should be paid atention to. At present, the risk factors of PCV massive bleeding are not completely clear, and its treatment methods are diverse, which requires a large number of studies to prove its effectiveness and establish expert diagnosis and treatment consensus.

目的：探讨运用Barrett Universal Ⅱ公式(BUⅡ公式)计算人工晶状体(intraocular lens,IOL)屈光力时，可选参数角膜横径，又称白到白(white-to-white,W T W)与晶状体厚度(lens thickness,LT)的实际应用价值。方法：采用单中心、前瞻性临床研究，连续纳入同一术者顺利进行白内障超声乳化吸除术联合MX60(IOL植入术患眼279眼，术前使用OA-2000非接触式光学生物测量仪测量眼部数据并计算IOL植入度数，代入B UⅡ公式保留或去掉可选参数WTW、LT计算预测结果，进一步根据患者眼轴长度(axial length,AL)分亚组分析。主要结局指标：随访患者至术后1个月以上，比较使用和未使用WTW和LT两个参数、BUⅡ公式预测误差(prediction error,PE)、绝对预测误差(absolute error,AE)、AE小于0.5 D所占比例。结果：总体1上，忽略W T W + LT，PE为-0.05 D(-0.26, 0.18)(P=0.011)，其他参数组合的PE与0比较差异无统计学意义(P>0.05)。各参数组合的AE比较差异无统计学意义(0.22~0.23 D，P= 0.404)。同时忽略WTW + LT时AE出现最大值(+1.5 D)。应用WTW + LT、忽略WTW + LT、忽略WTW和忽略LT时纳入患者AE ≤ 0.50 D的比例分别为80.65%、79.57%、80.65%和81.36%。在各眼轴亚组中，忽略LT时，AE ≤ 0.50 D的百分比在短眼轴亚组(80.00% vs.66.67%~73.33%)与长眼轴亚组(77.78% vs. 73.33%~75.56%)中较高。在中等眼轴亚组中，AE ≤ 0.50 D百分比代入全部参数时略高(83.11% vs. 80.82%~82.19%)，忽略WTW + LT计算时稍低(80.82%)。结论：使用BU Ⅱ计算IOL屈光力时，可选参数WTW和LT无论是否代入公式中，皆可得到相近的平均预测水平；但是，同时忽略WTW和LT可能出现较大预测误差。对于22 mm ≤ AL<26 mm眼，推荐代入全部参数计算；当AL≤ 22 mm或AL ≥ 26 mm，仅输入WTW的计算方法累积精确度更高，可优先采用。

Objective: To investigate the practical application value of the optional parameters of corneal horizontal diameter or white to white (WTW) and lens thickness (LT) a using Barrett Universal II formula. Methods: Single-center, prospective clinical study. Eligible 279 eyes who underwent uneventful phacoemulsification and enVista MX60 implantation by the same surgeon were consecutively enrolled. OA-2000 (Tomey, Japan) non-contact optical biometry was used to measure the ocular data and calculate the IOL implantation power preoperatively. The BU II network formula was used to retain or remove optional parameters WTW and LT, and the predicted results were calculated. Further subgroup analysis was conducted based on the patient's axial length. Main outcome measures: Follow up patients for more than 1 month after surgery, compare the proportion of using and not using WTW and LT parameters, BU II formula prediction error (PE), absolute prediction error (AE), and AE less than 0.5 D. Results: Overall, ignoring WTW + LT, the median PE was -0.05 D (-0.26, 0.18) (P = 0.011) , and there is no statistically significant difference in PE compared 0 for the other parameter combinations (P > 0.05). There was no significant difference in the median AE of each parameter combination (0.22~0.23 D, P = 0.404). While ignoring both WTW and LT, the maximum AE value (+1.5 D) was found. The proportion of patients with AE ≤ 0.50 D included in the application of WTW+LT, neglect of WTW+LT, neglect of WTW, and neglect of LT were 80.65%, 79.57%, 80.65%, and 81.36%, respectively in each axial subgroup, when LT was ignored, the percentage of AE ≤ 0.50 D was higher in the short axial subgroup (80% vs. 66.67%~73.33%) and the long axial subgroup (77.78% vs. 73.33%~75.56%). In the subgroup of moderate eye axis, the percentage of AE ≤ 0.50 D was slightly higher when all parameters were substituted (83.11% vs. 80.82%~82.19%), and slightly lower when WTW+LT calculation was ignored (80.82%). Conclusions: When applying Barrett Universal II to calculate the refractive power of artificial lenses, the optional parameters WTW and LT can obtain similar average prediction levels regardless of whether they are substituted into the formula; However, ignoring both WTW and LT may result in significant prediction errors. For eyes with a diameter of 22 mm ≤ AL<26 mm, it is recommended to use all parameters for calculation; When AL ≤ 22 mm or AL ≥ 26 mm, the calculation method that only inputs WTW has higher cumulative accuracy, and it is suggested to be prioritized.

目的：初步评价折叠顶压球囊(foldable capsule buckle,FCB)治疗孔源性视网膜脱离(rhegmatogenous retinaldetachment,RRD)的有效性、安全性以及手术可操作性。方法：裂孔位置距角膜缘后≥15 mm的采用前瞻性临床病例研究。选择2020年3月至2021年9月在济南明水眼科医院院行FCB植入术治疗裂孔位置距角膜缘后≥15 mm的10例RRD患者(10眼)。应用眼部B型超声、眼底照相评价手术效果。根据术后有无FCB是否暴露、复视情况、排斥反应、眼球运动障碍等术后并发症的发生情况评价手术的疗效和安全性。结果：随访6个月~2年。10例RRD患者在术后通过眼部B超、眼底照相及光学相干断层扫描(opticalcoherence tomography,OCT)评估视网膜均复位。1例合并黄斑区视网膜脱离的患者视力提高。9例患者术后出现复视，术后1~3个月复视消失，1例在术后4个月仍存在复视，行FCB取出，术后视网膜未出现再脱离，复视症状消失。结论：初步研究可确定折叠顶压球囊植入治疗裂孔位置比较靠后(距角膜缘后≥15 mm)且传统巩膜扣带术操作难度大的孔源性视网膜脱离安全、有效，对眼球损伤小，易于操作。

Objective: To preliminarily evaluate the effectiveness, safety and surgical operability of foldable capsule buckle (FCB) in the treatment of rhegmatogenous retinal detachment (RRD). Methods: It is a prospective clinical case study. Ten patients (10 eyes), with a distance of ≥ 15 mm from the posterior margin of the angular membrane at the location of the fissure, who underwent FCB implantation surgery for RRD at Jinan Mingshui Ophthalmology Hospital from March 2020 to September 2021 were enrolled. The surgical outcome was evaluated by B-ultrasound, fundus photography and optical coherence tomography (OCT). The surgical efficay and safety were evaluated by the postoperative complications, such as FCB exposure, diplopia, rejection, and eye movement limitation. Results: The mean follow-up time was 1 year (6 months to 2 years). Retinal reattachment was evaluated by B-ultrasound, fundus photography and OCT after operation in 10 patients. One patient with macular retinal detachment had improved visual acuity. 9 patients developed diplopia after operation, but diplopia disappears 1-3 months after operation. One patient still had diplopia 4 months after operation, and FCB was removed 4 months after operation. No retinal detachment occurred after operation, and the symptoms of diplopia disappeared.Conclusion: It is confirmed by this preliminary research that the implantation of the foldable capsule buckle is safe and effective to treat rhegmatogenous retinal detachment with a relatively posterior position (≥15 mm from the back of the corneal limbus) with little damage to the ocular and easy to operate, compared with the difficulty and complexity in traditional scleral buckling surgery.

随着人口老龄化、生活方式的改变，眼科疾病患病人数的增加、国家眼病诊疗相关政策的持续推动、居民健康意识的逐渐提升，眼科门急诊患者数量持续增长，亟需构建科学的眼科急诊预检分诊标准，合理配置医疗资源，确保患者得到及时、恰当的治疗。国外已有医院依据患者症状或体征的严重程度对患者进行等级划分，建立起相对成熟的眼科急诊预检分诊模式，我国目前尚没有统一的、权威的眼科急诊预检分诊标准，国内外现行的眼科急诊预检分诊模式的分诊精准度及临床适用性有待进一步探索。该文通过综述国内外眼科急诊分诊标准及应用评价、眼科远程急诊预检分诊方式研究进展，以期为构建符合我国国情的、科学有效的眼科急诊预检分诊标准、提高眼科急诊分诊质量提供参考。

With the aging of population, the changing of lifestyle and the increasing number of ophthalmic emergency patients,Chinese national policies related to ophthalmic diagnosis and treatment are continually promoted, and residents' health awareness are gradually improved, the volume of ophthalmic outpatients and emergency patients continues to increase. It is urgent needed to establish scientific ophthalmic emergency pre-examination and triage criteria, to reasonably allocate medical resources, and to ensure that patients receive timely and appropriate treatment. The relatively mature ophthalmic emergency pre-examination and triage models with the severity of patients' symptoms or physical signs,have been established in foreign hospitals. Currently, there is no unified and authoritative ophthalmic emergency triage criteria in China. The accuracy and clinical applicability of the existing ophthalmic emergency triage models at home and abroad need to be further explored. This article reviewed the ophthalmic emergency triage criteria and application evaluation at home and abroad, and remote emergency triage in ophthalmology, in order to provide a reference for establishing a scientific and effective ophthalmic emergency triage criteria comformed Chinese national conditions, and improving the quality of ophthalmic emergency triage.
