Subjective preferences for visual qualities of shapes and fonts have been separately reported. Such preferences are often similarly attributed to factors such as aesthetic impressions, attributed meaning from the visual properties, or processing fluency. Because shapes and fonts were rarely studied together, we investigated whether these qualities had a similar impact on preference judgment of object-word pairs. Each pair consisted of an abstract object with either preferred or disliked shape qualities and a pseudoword with either preferred or disliked font qualities. We found that only shape qualities, but not font qualities, influenced preference ratings of the object-word pairs, with higher preferences for pairs with preferred than disliked shapes. Moreover, eye movement results indicated that while participants fixated the word before the object, their prolonged fixation on the object when first attending to it might have contributed to the preference ratings. Nonetheless, other measures, including response times, total fixation numbers, and total dwell time, showed different patterns for shape and font qualities, revealing that participants attended more to objects with preferred than disliked shapes, and to words with disliked than preferred fonts. Taken together, these results suggest that shape and font qualities have differential influences on preferences and processing of objects and words.
对形状和字体的视觉质量的主观偏好已分别报道。这种偏好通常同样归因于诸如审美印象、视觉属性所赋予的意义或处理流畅性等因素。由于形状和字体很少被放在一起研究,我们调查了这些品质是否对客观词对的偏好判断有相似的影响。每一对都包含一个具有喜欢或不喜欢的形状特性的抽象对象和一个具有喜欢或不喜欢的字体特性的伪单词。我们发现,只有形状的质量,而不是字体的质量,影响了对对象词对的偏好评级,对喜欢的形状的偏好高于不喜欢的形状。此外,眼动结果表明,当参与者在注视物体之前注视单词时,他们第一次注视物体时对物体的长时间注视可能有助于偏好评级。然而,其他测量,包括反应时间、总注视次数和总停留时间,显示了形状和字体质量的不同模式,揭示了参与者更多地关注具有喜欢的形状而不是不喜欢的物体,以及不喜欢的字体而不是喜欢的字体的单词。综上所述,这些结果表明,形状和字体质量对物体和单词的偏好和处理有不同的影响。

The current diagnostic aids for acute vision loss are static flowcharts that do not provide dynamic, stepwise workups. We tested the diagnostic accuracy of a novel dynamic Bayesian algorithm for acute vision loss. Seventy-nine “participants” with acute vision loss in Windsor, Canada were assessed by an emergency medicine or primary care provider who completed a questionnaire about ocular symptoms/findings (without requiring fundoscopy). An ophthalmologist then attributed an independent “gold-standard diagnosis”. The algorithm employed questionnaire data to produce a differential diagnosis. The referrer diagnostic accuracy was 30.4%, while the algorithm’s accuracy was 70.9%, increasing to 86.1% with the algorithm’s top two diagnoses included and 88.6% with the top three included. In urgent cases of vision loss (n = 54), the referrer diagnostic accuracy was 38.9%, while the algorithm’s top diagnosis was correct in 72.2% of cases, increasing to 85.2% (top two included) and 87.0% (top three included). The algorithm’s sensitivity for urgent cases using the top diagnosis was 94.4% (95% CI: 85–99%), with a specificity of 76.0% (95% CI: 55–91%). This novel algorithm adjusts its workup at each step using clinical symptoms. In doing so, it successfully improves diagnostic accuracy for vision loss using clinical data collected by non-ophthalmologists.
目前急性视力丧失的诊断辅助工具是静态流程图,不能提供动态的、逐步的检查。我们测试了一种新的动态贝叶斯算法对急性视力丧失的诊断准确性。在加拿大温莎,79名急性视力丧失的“参与者”由急诊医学或初级保健提供者进行评估,他们填写了一份关于眼部症状/发现的问卷(不需要眼底镜检查)。一位眼科医生随后给出了独立的“金标准诊断”。该算法采用问卷数据进行鉴别诊断。转诊者的诊断准确率为30.4%,而算法的诊断准确率为70.9%,包括算法前两名诊断准确率为86.1%,包括前三名诊断准确率为88.6%。在54例紧急视力丧失病例中,转诊诊断正确率为38.9%,而算法的最高诊断正确率为72.2%,分别增加到85.2%(前2例)和87.0%(前3例)。该算法对使用最高诊断的紧急病例的敏感性为94.4% (95% CI: 85-99%),特异性为76.0% (95% CI: 55-91%)。这种新颖的算法根据临床症状调整每一步的检查结果。在这样做的过程中,它成功地提高了使用非眼科医生收集的临床数据对视力丧失的诊断准确性。

Myopia is becoming more common across the world, affecting approximately two billion people and rising. Different kinds of therapies (optical, pharmaceutical, environmental, or behavioral) have been proposed to decrease myopia progression, but with variable results and a lack of standardization. The evidence that targeted myopic defocus inhibits eye length growth has paved the way for several contact and spectacle lense designs to induce a peripheral defocus, thus slowing myopia progression, but the perfect configuration has yet to be defined. One of the newest and more promising approaches in this field is the use of Defocus Incorporated Multiple Segments (DIMS) lenses. These lenses are built from the assumption that targeted myopic defocus, produced by 396 mid-peripheral lenslets with positive power, inhibits eye length growth. Recent studies have highlighted the effectiveness of these lenses compared to children who had worn single vision spectacle lenses, in terms of myopia control and tolerability. Despite the evidence that these lenses can help slow down the progression of myopia, the occasional mid-peripheral aberrations they can induce, as well as the overall eye strain that comes with wearing them, should not be overlooked. The aim of this review is to give attention to the advantages and the shortfalls of this new approach and to evaluate its effectiveness in clinical practice.
近视在世界各地变得越来越普遍,影响着大约20亿人,而且这个数字还在上升。不同种类的治疗方法(光学、药物、环境或行为)已被提出以减少近视进展,但结果不一且缺乏标准化。有证据表明,有针对性的近视离焦会抑制眼长增长,这为一些隐形眼镜和眼镜设计铺平了道路,以诱导周围离焦,从而减缓近视的进展,但完美的配置尚未确定。在这一领域最新和最有前途的方法之一是使用离焦合并多段(DIMS)镜头。这些隐形眼镜是基于这样一种假设,即396个具有正能量的中外围晶状体产生的针对性近视离焦会抑制眼睛的长度增长。最近的研究强调,在近视控制和耐受性方面,与戴单视力眼镜的儿童相比,这些镜片的有效性。尽管有证据表明这些镜片可以帮助减缓近视的进展,但它们可能引起的偶尔的中周像差,以及佩戴它们带来的整体眼睛疲劳,都不应被忽视。本综述的目的是关注这种新方法的优点和不足,并评估其在临床实践中的有效性。

Smartphone apps are becoming increasingly popular in ophthalmology, one specific area of their application being toric intraocular lens (IOL) surgery for astigmatism correction. Our objective was to identify, review and objectively score smartphone apps applicable to toric IOL calculation and/or axis alignment. This review was divided into three phases. A review was conducted on four major app databases (phase I): National Health Service (NHS) Apps Library, Google Play Store, Apple App Store and Amazon Appstore. A systematic literature review (phase II) was conducted to identify studies for included apps in phase I of our study. Keywords used in both searches included: “toric lens”, “toric IOL”, “refraction”, “astigmatism”, “ophthalmology”, “eye calculator”, “ophthalmology calculator” and “refractive calculator”. Included apps were objectively scored (phase III) by three independent reviewers using the mobile app rating scale (MARS), a validated tool that ranks the quality of mobile health apps using a calculated mean app quality (MAQ) score. Phase I of our study screened 2428 smartphone apps, of which six apps for toric IOL calculation and four apps for axis marking were eligible and were selected for quantitative analysis. Phase II of our study screened 477 studies from PubMed, Medline and Google Scholar. Three studies validating two apps (toriCAM, iToric Patwardhan) in a clinical setting as adjunct tools for preoperative axis marking were identified. Phase III ranked Toric Calculator for iPhone (Apple iOS, MAQ 4.13; average MAQ 3.34 ± 0.54) as the highest-scoring toric IOL calculator, and iToric Patwardhan (Android OS, MAQ 4.13; average MAQ 3.41 ± 0.44) was the highest-scoring axis marker in our study. Our review identified and objectively scored ten smartphone apps available for toric IOL surgery adjuncts. Toric Calculator for iPhone and iToric Patwardhan were the highest-scoring toric IOL calculator and axis marker, respectively. Current literature, though limited, suggests that axis marking smartphone apps can achieve similar levels of misalignment reduction when compared to digital systems.
智能手机应用程序在眼科领域越来越受欢迎,其中一个特定应用领域是用于矫正散光的环形人工晶状体(IOL)手术。我们的目标是识别,审查和客观评分适用于环形人工晶状体计算和/或轴对齐的智能手机应用程序。这次审查分为三个阶段。对四个主要应用数据库(第一阶段)进行了审查:国民健康服务(NHS)应用程序库、b谷歌Play Store、苹果应用程序商店和亚马逊应用程序商店。我们进行了系统的文献综述(II期),以确定我们研究I期中包含的应用程序的研究。在这两个搜索中使用的关键词包括:“环状体”、“环状体人工晶体”、“屈光”、“散光”、“眼科”、“眼科计算器”、“眼科计算器”和“屈光计算器”。纳入的应用程序由三名独立评论者使用移动应用评级量表(MARS)客观评分(第三阶段),这是一种经过验证的工具,使用计算的平均应用程序质量(MAQ)分数对移动健康应用程序的质量进行排名。我们的研究第一阶段筛选了2428个智能手机应用程序,其中6个应用程序用于环形人工晶状体计算和4个应用程序用于轴标记符合条件,并选择进行定量分析。我们的二期研究筛选了来自PubMed、Medline和谷歌Scholar的477项研究。三个研究验证了两种应用程序(toriCAM, iToric Patwardhan)在临床环境中作为术前轴标记的辅助工具。第三阶段排名topic Calculator for iPhone(苹果iOS, MAQ 4.13;平均MAQ为3.34±0.54)为评分最高的人工晶状体计算器,iToric Patwardhan (Android OS, MAQ 4.13;平均MAQ(3.41±0.44)为本研究中评分最高的轴向标志物。我们的综述确定并客观评分了10个智能手机应用程序,可用于环形人工晶状体手术辅助器具。iToric Calculator for iPhone和iToric Patwardhan分别是得分最高的环形人工晶体计算器和轴标记器。目前的文献虽然有限,但表明与数字系统相比,坐标轴标记智能手机应用程序可以实现类似水平的减少错位。

This research aims to understand the different success factors of a savings and credit cooperative (SACCO) through the study of the managerial dimensions and its style of governance. Semi-directed interviews were conducted with three directors who are founding members of the Haitian ‘MEN ALE MEN VINI (MAMEV)’ cooperative. NVIVO version 11 software was used as a tool for coding and data analysis. The interviews concluded that the success of the cooperative is linked to the personal attributes of the various directors, effective management, good governance and an efficient decision-making system. This research also showed that the success of cooperatives is partly related to the notoriety, leadership, willingness and level of commitment of its directors. It is also related to the good governance manifested in the participatory management and decision-making, the transparency of the organization and the quality of the work of the cooperatives. Also, the research has shown that anchoring the cooperative in the community, bringing the population closer to the cooperative and offering services adapted to the community’s needs have a positive influence on the membership and make the cooperative more sustainable. Finally, the research showed that the adoption of an effective governance mode helped to ensure the sustainability, viability, modernity, efficiency and social, financial and economic soundness of the cooperative. The experience of this SACCO not only helped the members to counteract the myth of incapacity that prevailed in Haitian community at the time but also improved the living conditions of the members as well as those of community members. The research provides a novel contribution to the resilient and sustainable model of governing and managing SACCOs. It also presents a new model of the Success Keys of SACCOs.
本研究旨在透过研究储蓄信贷合作社的管理层面及其治理风格,了解其不同的成功因素。对海地“MEN ALE MEN VINI (MAMEV)”合作社创始成员的三名主任进行了半定向采访。使用NVIVO version 11软件进行编码和数据分析。面谈的结论是,合作社的成功与各主任的个人素质、有效的管理、良好的管理和有效的决策制度有关。这项研究还表明,合作社的成功部分与其董事的名声、领导、意愿和承诺水平有关。它还与参与性管理和决策、组织的透明度和合作社工作的质量所体现的善政有关。此外,研究表明,将合作社锚定在社区中,使人口更接近合作社,并提供适应社区需求的服务,对社员产生积极影响,使合作社更具可持续性。最后,研究表明,采用有效的治理模式有助于确保合作社的可持续性、生存能力、现代性、效率和社会、财务和经济健康。该合作组织的经验不仅帮助成员消除了当时海地社区普遍存在的无能的神话,而且还改善了成员以及社区成员的生活条件。该研究为治理和管理sacco的弹性和可持续模式提供了新的贡献。并提出了一种新的sacco成功关键模式。

For moderate-to-severe glaucoma, trabeculectomy remains the “gold standard” intraocular pressure (IOP)-lowering treatment; nonetheless, this method requires extensive post-operative maintenance. Microinvasive glaucoma surgery (MIGS) treatments are designed to lessen intra- and post-operative care burden while offering an acceptable IOP decrease for individuals with mild to moderate glaucoma. The PreserFlo® MicroShunt (previously InnFocus MicroShunt) is an 8.5 mm glaucoma drainage device manufactured from poly(styrene-block-isobutylene-block-styrene) (SIBS), an extremely biocompatible and bioinert material. The lumen is narrow enough to prevent hypotony, but big enough to avoid being obstructed by sloughed cells or pigment. The device is implanted ab externo, as a stand-alone procedure or in conjunction with cataract surgery, with intraoperative mitomycin C, and a bleb is produced under the conjunctiva and Tenon’s capsule. The MicroShunt was CE-marked in 2012 and designed for primary open-angle glaucoma, the IOP of which remains uncontrolled after maximally tolerated topical treatment. Several clinical trials evaluating the MicroShunt’s long-term safety and effectiveness have been conducted, highlighting the effectiveness of the device over time, along with a tolerable safety profile. The present review aims to gather evidence of PreserFlo’s effectiveness and safety results almost 10 years after its introduction, and furthermore, to compare it with other MIGS and with the gold-standard trabeculectomy for glaucoma management.
对于中重度青光眼,小梁切除术仍然是降低眼压的“金标准”;然而,这种方法需要广泛的术后维护。微创青光眼手术(MIGS)治疗旨在减轻术中和术后护理负担,同时为轻度至中度青光眼患者提供可接受的IOP降低。PreserFlo®MicroShunt(以前的InnFocus MicroShunt)是一种8.5毫米青光眼引流装置,由聚苯乙烯块-异丁烯块-苯乙烯块(SIBS)制成,这是一种极具生物相容性和生物惰性的材料。管腔足够窄,以防止低斜视,但足够大,以避免被脱落的细胞或色素阻塞。该装置可以作为一个单独的手术植入体外,也可以与白内障手术一起植入术中丝裂霉素C,并在结膜和Tenon囊下产生一个水泡。MicroShunt于2012年获得ce认证,设计用于原发性开角型青光眼,其IOP在最大耐受局部治疗后仍不受控制。已经进行了几项评估MicroShunt长期安全性和有效性的临床试验,强调了该设备随着时间的推移的有效性,以及可容忍的安全性。本综述旨在收集PreserFlo在引入近10年后的有效性和安全性结果的证据,并进一步将其与其他MIGS和治疗青光眼的金标准小梁切除术进行比较。

The device is implanted ab externo, as a stand-alone procedure or in conjunction with cataract surgery, with intraoperative mitomycin C, and a bleb is produced under the conjunctiva and Tenon’s capsule. The MicroShunt was CE-marked in 2012 and designed for primary open-angle glaucoma, the IOP of which remains uncontrolled after maximally tolerated topical treatment. Several clinical trials evaluating the MicroShunt’s long-term safety and effectiveness have been conducted, highlighting the effectiveness of the device over time, along with a tolerable safety profile. The present review aims to gather evidence of PreserFlo’s effectiveness and safety results almost 10 years after its introduction, and furthermore, to compare it with other MIGS and with the gold-standard trabeculectomy for glaucoma management.","PeriodicalId":49121,"journal":{"name":"Spatial Vision","volume":"91 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-02-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89151643","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Purpose: The present study evaluates the differences in the prevalence of the signs and symptoms of ocular surface disease (OSD) in patients with PEX glaucoma (PEXG), compared to other glaucoma types (non-PEXG). Methods: Patients with non-PEXG and PEXG were prospectively examined for the presence and severity of OSD signs and questioned for symptoms using the OSDI (ocular surface disease index) questionnaire. Results: 116 patients were prospectively enrolled (58 non-PEXG and 58 PEXG). PEXG subjects who were older, had lower central corneal thickness (CCT) values, at a more advanced glaucoma stage and required more IOP lowering drops. OSD signs were prevalent in both groups: conjunctival hyperemia (74.5% non-PEXG vs. 94.8% PEXG), eyelid redness (70.7% vs. 96.6%), conjunctival (74.1% vs. 93.1%) and corneal fluorescein staining (81% vs. 93.1%) and abnormal TFBUT (82.8% vs. 87.9%). When adjusted for potential confounders, (older age, thinner CCT, more advanced glaucoma in PEXG) eyelid redness remained the only parameter significantly associated with PEXG, being 11 times more likely to occur in this group (p = 0.037). Conclusion: Subjects with PEXG presented a higher frequency of signs of OSD compared to other glaucoma types. When accounting for confounding factors, the only difference between the groups was the significantly higher presence (11 times more likely) of eyelid redness in PEXG, suggesting, in addition to glaucoma treatment, the impact of PEX on ocular surface integrity.
目的:本研究评估PEX型青光眼(PEX型)患者与其他类型青光眼(非PEX型)相比,眼表疾病(OSD)的体征和症状患病率的差异。方法:采用OSDI(眼表疾病指数)问卷对非PEXG和PEXG患者进行前瞻性检查,检查OSD体征的存在和严重程度,并对症状进行询问。结果:116例患者被纳入前瞻性研究(58例非PEXG和58例PEXG)。PEXG受试者年龄较大,角膜中央厚度(CCT)值较低,青光眼阶段较晚,需要更多的IOP降眼压。OSD症状在两组中都很普遍:结膜充血(74.5%非PEXG vs 94.8% PEXG),眼睑发红(70.7% vs 96.6%),结膜(74.1% vs 93.1%)和角膜荧光素染色(81% vs 93.1%)以及TFBUT异常(82.8% vs 87.9%)。在校正潜在混杂因素后,(年龄较大、CCT较薄、PEXG患者青光眼较晚期)眼睑发红仍然是唯一与PEXG显著相关的参数,在该组中发生的可能性是PEXG的11倍(p = 0.037)。结论:与其他青光眼类型相比,PEXG患者出现OSD体征的频率更高。当考虑到混杂因素时,两组之间的唯一区别是PEX治疗中眼睑发红的发生率明显更高(可能性高出11倍),这表明除了青光眼治疗外,PEX还对眼表完整性有影响。

Cerebellar tumors often affect the eye movement centers located in vermis, negatively affecting cognitive development and learning abilities in children. Previous research has established that patients who survived cerebellar tumors tend to demonstrate various saccadic impairments (e.g., hypermetria) and poor gaze stability as compared to healthy controls. The aim of the current study was to evaluate the influence of oculomotor deficits in such patients on reading parameters. A total of 112 children (8–17 y.o.), 65 of whom survived cerebellar tumors, participated in the study. The study design included several oculomotor and reading tasks. Eye movements were recorded every 1/60 s monocularly with an Arrington eye tracker. We observed profound reading impairments in the patients as compared to healthy children, including longer reading time, greater numbers of fixations and regressive saccades, and longer fixation durations. We also found significant correlations between changes in basic oculomotor functions and reading parameters. The patients also demonstrated gaze fixation instability, large number of fixations, and long scanpath reflecting the return of the gaze to the already counted objects. Thus, oculomotor changes caused by cerebellar tumor and its treatment led to disturbances in such neurocognitive activity as reading. Our findings emphasize the necessity of considering these deficits in cerebellar tumor survivors when designing rehabilitation protocols.
小脑肿瘤经常影响位于蚓部的眼动中心,对儿童的认知发展和学习能力产生负面影响。先前的研究已经确定,与健康对照者相比,小脑肿瘤存活的患者往往表现出各种跳眼损伤(例如,高血速)和较差的凝视稳定性。本研究的目的是评估这些患者的动眼肌缺陷对阅读参数的影响。共有112名儿童(8-17岁)参与了这项研究,其中65名小脑肿瘤幸存者。研究设计包括几个动眼力和阅读任务。用阿灵顿眼动仪单目记录每1/60秒眼球运动。我们观察到,与健康儿童相比,患者存在严重的阅读障碍,包括更长的阅读时间,更多的注视和退行性扫视,以及更长的注视持续时间。我们还发现基本动眼肌功能的变化与阅读参数之间存在显著的相关性。患者还表现出注视不稳定,注视次数多,扫描路径长,反映了目光返回到已计数的物体上。因此,小脑肿瘤引起的动眼病改变及其治疗导致阅读等神经认知活动的障碍。我们的研究结果强调了在设计康复方案时考虑小脑肿瘤幸存者这些缺陷的必要性。

Glaucoma is the most common cause of permanent blindness in the world, caused by a progressive optic neuropathy. Patients with glaucoma are often treated with topical medicines therapy in order to reduce intra-ocular pressure (IOP). On the other hand, laser therapies, with the introduction of Argon Laser Trabeculoplasty (ALT) and successively with Selective Laser Trabeculoplasty (SLT), were reported to be effective in IOP control, with low adverse effect rates. In recent years, the micropulse laser, a subthreshold laser technology, was introduced with the goal of reducing side effects while maintaining the effectiveness of the laser treatments. Several studies focused on Micropulse Diode Laser Trabeculoplasty (MDLT) in open-angle glaucoma, to evaluate its effectiveness and possible side effects. Promising results were reported, but irradiation circumstances have not been standardized yet and its role as a substitute for previous laser techniques has yet to be defined. As a result, the goal of this review was to analyze the physical principles at the basis of MDLT and to frame it in the open-angle glaucoma management setting, highlighting the advantages and shortfalls of this technique.
青光眼是世界上最常见的永久性失明的原因,由进行性视神经病变引起。青光眼患者通常采用局部药物治疗,以降低眼压。另一方面,激光治疗,包括氩激光小梁成形术(ALT)和选择性激光小梁成形术(SLT),被报道在IOP控制方面是有效的,不良反应发生率低。近年来,微脉冲激光作为一种亚阈值激光技术被引入,目的是在保持激光治疗有效性的同时减少副作用。微脉冲二极管激光小梁成形术(MDLT)治疗开角型青光眼的疗效及可能的副作用。报道了有希望的结果,但辐照环境尚未标准化,其作为以前激光技术的替代品的作用尚未确定。因此,本综述的目的是分析MDLT基础的物理原理,并将其纳入开角型青光眼的治疗环境,强调该技术的优点和不足。
