目的:探究囊袋张力环(CTR)植入对五种新一代人工晶状体(IOL)计算公式[Barrett Universal Ⅱ (BUⅡ), Emmetropia Verifying Optical (EVO), Kane, Pearl-DGS和Hill-RBF 2.0]在高度近视患者中预测准确性的影响。方法:前瞻性病例对照研究。观察2020年12月—2021年9月于陕西省眼科医院就诊的眼轴长度(axial length,AL)≥ 27.00 mm行白内障联合IOL(AR40E, 美国强生)植入术的患者。术眼随机分为植入CTR组(A组)和未植入CTR组(B组)。术前根据IOLMaster700测量眼部参数,使用BU Ⅱ公式计算所需IOL度数。记录术后1周、1个月及3个月实际等效球镜度(spherical equivalent,SE),计算并比较五种公式预测误差(prediction error,PE)和绝对屈光预测误差(absolute Error,AE)。将A组和B组分别分为A1组(27.00 mm ≤ AL ≤ 30.00 mm)和A2组(AL>30.00 mm);B1组(27.00 mm ≤ AL ≤ 30.00 mm)和B2组(AL >30.00 mm),分析不同AL范围内CTR植入对公式预测准确性的影响。结果:共纳入患者63例(89眼),年龄(55.93±10.17)岁,术前AL为(30.30±2.18)mm。A组、A1组及A2组术后不同时间SE值比较差异均无统计学意义(P>0.05),B组、B1组及B2组术后1周与1个月,术后1周与3月SE值分别比较差异有统计学意义(P<0.05),术后1个月与3个月比较,差异无统计学意义(P>0.05)。A组、B组、A1组、A2组、B1组和B2组各组中五种公式的AE值比较差异均无统计学意义(均P>0.05)。植入CTR后五种公式的预测误差变化比较差异无统计学意义(P>0.05)。结论:对于AL ≥27.00 mm的白内障患者,植入CTR组术后1周屈光度趋于稳定,未植入组术后1个月屈光度趋于稳定。CTR植入对五种公式预测准确性和选择无影响,五种计算公式均可正常选择。
Objective: To investigate the predictive accuracy and effect of capsular tension ring (CTR) implantation with five new generation intraocular lens (IOL) calculation formulas [Barrett Universal Ⅱ (BU Ⅱ), Emmetropia Verifying Optical(EVO), Kane, Pearl-DGS and Hill-RBF 2.0] in high myopia patients. Methods: This is a prospective case-control study. The patients were enrolled with an axial length (AL)≥27.00 mm, and underwent cataract surgery with AR40E IOL implantation at the Shaanxi Eye Hospital from December 2020 to September 2021. The patients were randomly assigned to the CTR implantation group (group A) and the non-CTR implantation group (group B). With the ocular parameters measured by the IOLMaster700, the IOL power was calculated with the BUⅡformula before surgery. The postoperative actual equivalent spherical diopter (SE) were recorded,and the predicted error (PE) and absolute error (AE) using the five formulas were recorded and compared at 1 week, 1 month, and 3 months, repsectively. Group A was divided to A1 (27.00 mm ≤ AL ≤ 30.00 mm) and A2 (AL>30.00 mm), and group B was divided to B1 (27.00 mm ≤ AL ≤ 30.00 mm) and B2 (AL>30.00 mm). The effects of CTR implantation and the accuracy of the formulas were analyzed with different AL ranges. Results: A total of 63 patients (89 eyes) were included, aged (55.93±10.17) years old, with preoperative AL (30.30± 2.18)mm. There was no statistically significant difference in SE between groups A, A1, and A2 (P>0.05) at different postoperative times. While there was a statistically significant difference in SE between groups B, B1, and B2 (P < 0.05) at 1 week and 1 month after surgery, and between 1 week and 3 months after surgery. There was no statistically significant difference between 1 month and 3 months after suergery (P>0.05). There was no significant difference in the AE using the five formulas among groups A, B, A1, A2, B1, and B2 (P>0.05). There was no statistically significant difference in prediction error changes among the five formulas after CTR implantation (P>0.05). Conclusion: For cataract patients with AL ≥ 27.00 mm, the refractionvalue in the CTR implantation group tended to stabilizeafter one week of surgery. While in the non-CTR implantation group, the refractionvalue tended to stabilize after one month. CTR implantation had no effect on the accuracy and selection of the five formula, and the five IOL calculation formulas can be normally selected.
据统计,目前全球有近14亿近视人口,近视已成为全球主要的健康问题。近视不仅影响个人的视力健康,还可能引发多种严重的并发症,如高度近视相关的黄斑变性和视网膜脱离等,严重时可导致失明。除了对个人健康的影响,近视还带来了巨大的经济负担,包括直接医疗成本(如眼镜、隐形眼镜、矫正手术等费用)和间接成本(如生产力下降、学习能力降低和生活质量的下降)。在中国,近视的问题尤其显著,近视患病率居高不下,这不仅对个人健康构成威胁,也对社会和经济造成重大影响。国际上,近视的经济负担研究涵盖了医疗直接成本、患者时间成本及生产力损失等方面,可以帮助政府和卫生部门了解近视疾病的经济影响,从而制定合理的公共卫生政策和资源分配策略,优化医疗资源使用,减少社会成本。该文从近视疾病经济负担的构成及其测算方式、国内外经济负担现况等方面对近视疾病经济负担进行简要综述,旨在提供一个关于近视疾病经济负担的综合性认识,指出当前研究的方向和成果,以及预防近视和减轻其经济负担的重要性,为未来研究提供方向和基础。
It is estimated that there are nearly 1.4 billion myopic people in the world, and myopia becomes a significant global health problem. Myopia not only affects visual health, but also leads to serious complications such as macular degeneration and retinal detachment, which can cause blindness in severe cases. Apart from its impact on health, myopia also imposes a substantial economic burden. This burden includes direct medical costs (e.g., expenses for eyeglasses, contact lenses, and corrective surgeries) as well as indirect costs (e.g., reduced productivity, learning abilities, and quality of life). The prevalence of myopia is particularly high in China, posing a threat not only to individual health, but also to society and the economy. International studies on the economic burden of myopia have examined the direct medical costs, patient time costs and productivity loss. These studies help governments and health authorities understand the economic impact of myopia to develop effective public health and resource allocation strategies.. By optimizing medical resources and reducing social costs, these measures aim to alleviate the economic burden. This article provides an overview of the economic burden of myopia, including its definition, measurement, current status at home and abroad, and the importance of prevention and alleviation. It also highlights the current research directions and findings, to provide focusing fields and foundations for future research.
随着近视人口的逐年增长,近视已经成为全球关注的热点问题。如何预防近视、控制近视进展、减少病理性近视的发生、减少近视的成本投入是临床工作及科学研究的主要目的。阿托品是目前防控近视的主要药物方法,实验室研究及临床试验均已证实其显著的近视防控效果。美国眼科学会推荐使用0.01%低浓度阿托品,目前报道其近视防控效果为50%~53%。本文汇总了近年来近视防控相关的临床与实验室研究,对阿托品近视防控效果、其相关影响因素(如浓度、个体差异、生物利用度等)以及作用机制等方面的研究进展进行归纳综述,并分析了阿托品用于临床儿童近视防控工作存在的困难与挑战。
As the population of myopia grows rapidly, myopia has become a hot issue of global concern. Preventing myopia and slowing the progression of myopia to reduce the occurrence of pathological myopia and reduce the cost of myopia is the main purpose of related clinical work and scientific researches. Currently, atropine is the main drug for the prevention and control of myopia, and both laboratory studies and clinical trials have confirmed its effect. The American Academy of Ophthalmology recommends the use of 0.01% atropine, which is reported to be 50% to 53% effective in preventing and controlling myopia. This review collects the clinical and laboratory researches in decades to summarize the study progress in atropine for preventing and controlling myopia, including the clinical application effects, the influencing factors such as concentration, individual differences, bioavailability, and the related mechanisms. We also highlight the existing difficulties and challenges in the use of atropine in clinic.
高度近视(high myopia,HM)作为一种特殊类型的屈光型眼病,不仅会导致进行性、退行性眼底改变,其视神经损伤的患病率也很高。青光眼是全球范围内最常见的一种不可逆致盲性眼病,原发性开角型青光眼(primary open-angle glaucoma,POAG)是最常见的青光眼类型。近年来的研究发现HM与POAG的病理改变存在相似之处。由于HM眼底改变与早期POAG眼底改变容易混淆,HM患者早期发现POAG对延缓或阻止疾病进展很重要。HM患者长期随访不仅要观察黄斑病变,视神经形态与结构改变的观察也不容忽视。
As a special type of refractive eye disease, high myopia (HM) not only causes progressive and degenerative fundus changes, but also has a high prevalence of optic nerve damage. Glaucoma is the most common form of irreversible blinding eye diseases worldwide, among which, primary open-angle glaucoma (POAG) is the most common type. In recent studies, HM is found to have similarities on pathological changes as that of POAG. And HM fundus changes are easily confused with early stage POAG fundus changes; thus, the early detection of POAG on HM patients is highly important on disease deferment or prevention of disease progression. Macular degeneration as well as optic nerve morphology and structural changes are to be observed in the long-term follow-up for HM patients.

近视防控已经上升到我国国家战略层面,高度近视引起的视神经病变会损害视功能,但在临床上常常被忽视。OCT可以非侵入、高分辨率、快速以及可重复地定量视网膜各层厚度,是评估高度近视相关视神经病变的有力工具。由于高度近视常合并视盘和盘周的改变,视神经纤维层厚度的定量常出现误差。近年来,学者开始聚焦于黄斑区神经节细胞复合体(ganglion cell complex,GCC)厚度的研究,但其在高度近视眼中的变化规律尚不统一。该文针对近年来高度近视眼黄斑区GCC的测量规范、诊断价值、变化规律等进行综述,以期提高眼科医师对高度近视视神经病变的重视和研究水平。
Myopia prevention and control has risen to the national strategic level in China. Optic neuropathy caused by high myopia can damage visual function, but it is often ignored in clinical practice Optical coherence tomography (OCT) characterized by non-invasiveness, high resolution, rapid, and repeatable quantifying the thickness of each layer in the retina has emerged as a powerful tool for evaluating high myopia related optic neuropathy. Due to the changes in and near the optic disc in high myopia, errors often occur in the quantification of the thickness of the optic nerve fiber layer. In recent years, researchers have gradually focused on the study of the thickness of ganglion cell complex (GCC), but the regularity of its changes in high myopia is not yet unified. This article reviews the measurement specifications, diagnostic values, and change rules of GCC in the macular region of high myopia in recent years, in order to improve the attention and research level of ophthalmologists on high myopia optic neuropathy.
