[Thésaurus Mesh]RechercheRésumé : his year in science has provided some major advances and some enduring challenges. On the global stage, China continues to grow as a formidable force in research and discovery as it has for the last several decades. The total number of citable documents published worldwide in 2018 (the most recent full year) has grown to 3.5 million from 3.4 million in 2017. During this same period, the U.S. National Science Foundation reported that China had, for the first time, overtaken the United States in total scientific publications. Reports from SCImago show nearly equivalent numbers of publications for the two countries (United States: 570,104; China: 569,227). However, the citations to those publications remain higher in the United States (528,000; ranked first) compared to China (399,000; ranked second). Another way to compare the impact of scientific output is to look at the h-index, which combines the number of publications and the number of citations to those publications. The United States has a 2018 h-index of 2222 (2222 articles cited 2222 or more times), followed by the United Kingdom (1373), Germany (1203), Canada (1102), and France (1094). China ranks 13th in h-index (794). For those who enjoy publication metric trivia, San Marino was the country with the highest rank for citations per article (15.3) and a total of 38 publications, which emphasizes the potential folly associated with metric abuse. The 2019 investments in research and development by the United States are estimated at $581 billion (and growing slowly), with China at $519 billion and climbing steadily and rapidly ($400 billion in 2018). China's investments in research funding will likely eclipse gross research and discovery spending in the United States within the next 5 years (Fig. 1). The United States remains the world's top destination for students seeking advanced research training (PhD and postdoctoral students). In summary, the research landscape continues to expand with growing influence from China and other eastern countries who have made significant investments in research infrastructure over the past several decades.

[Thésaurus Mesh]OptométrieRésumé : SIGNIFICANCE The National Board of Examiners in Optometry recognizes the need for innovation and is creating a multidimensional clinical examination to parallel advancements within optometry. As optometry evolves, so must the assessments which form the path to optometric licensure. The current performance-based Part III, Clinical Skills Examination, is undergoing a transformation to best assess the diversity of knowledge, skills, and abilities needed to practice contemporary optometry. The objectives for the new clinical examination include increasing clinical authenticity, prioritizing the most essential and relevant skills, and emphasizing patient-centered care. This initiative is evidence based and consistent with best practices within the larger assessment community.

BUT Le but de cette étude était de rapporter un cas rare de paralysie du regard horizontal bilatéral d'une lésion supranucléaire chez un patient avec un diagnostic récent de sclérose en plaques.
RAPPORT DE CAS Une femme afro-américaine de 43 ans a présenté d'urgence une évaluation de son incapacité à déplacer ses yeux dans l'un ou l'autre des yeux horizontaux. Les mouvements verticaux conjugués sont restés intacts, tout comme trois des quatre muscles extraoculaires avec test réflexe vestibulo-oculaire horizontal, suggérant une paralysie supranucléaire. L'imagerie par résonance magnétique a révélé deux lésions démyélinisantes dans ses pons inférieurs, ce qui a épargné ses voies de regard horizontales nucléaires et internucléaires, ainsi que trois des quatre muscles extraoculaires de sa voie de regard horizontal infranucléaire, comme en témoigne son réflexe vestibulo-oculaire en grande partie intact. Cela suggère des lésions bilatérales de formation réticulaire pontique paramédian (supranucléaire) et une paralysie du nerf abducens gauche légère (infranucléaire).
CONCLUSIONS Une évaluation approfondie des motilités extraoculaires et une solide compréhension des composants supranucléaires, nucléaires, internucléaires et infranucléaires de la voie du regard horizontal peuvent aider à identifier les paralysies du regard difficiles lorsqu'elles sont rencontrées en milieu clinique. Une neuroimagerie appropriée peut ensuite être effectuée en mettant l'accent sur l'emplacement présumé de la ou des lésions en fonction des résultats cliniques du patient.Permalink : https://bibliotheque.helb-prigogine.be/opac_css/index.php?lvl=notice_display&id= [article]Exemplaires

[Thésaurus Mesh]Troubles de la visionRésumé : SIGNIFICANCE Optometry is desperately needed to combat the increasing rate of avoidable visual impairment that goes undiagnosed largely owing to the lack of integration of eye care services with primary care medicine. Government leaders are actively discussing substantive changes to health care legislation that will impact optometrists and their patients. The importance of a regular eye examination for disease prevention has long been undervalued in the setting of primary care. Consequently, many serious and potentially treatable ocular and systemic diseases go undiagnosed. Despite clear indicators that vision impairment increases the risk of morbidity and mortality from chronic systemic disease and decreases quality of life, vision health remains among the greatest unmet health care needs in the United States. To improve vision care services for all Americans, we must focus our attention on two central themes. First, we must educate the public, health care professionals, and policymakers on the importance of routine eye care as a preventive measure in the setting of primary care. Next, we need to recognize that optometrists, through their geographic distribution and advanced training, are in a strategic position to deliver integrated, comprehensive, cost-effective eye care services for individuals most in need. In this perspective, we discuss a model for integrating optometric services with the practice of primary care medicine to facilitate early detection of both eye and systemic disease while reducing serious and preventable health-related consequences.

[Thésaurus Mesh]Troubles de la visionRésumé : SIGNIFICANCE The Indian translated and culturally adapted version of the vision-related activity limitation (VRAL) item bank is a validated instrument to assess the difficulty in performing daily activities by cataract patients and can also be used to capture self-reported changes in ability to perform daily activities after cataract surgery.
PURPOSE The purpose of this study was to document (a) translation, cross-cultural adaptation of VRAL item bank into an Indian language, and (b) its validation using Rasch analysis in a South Indian cataract population.
METHODS At the first stage, a translated Indian version of VRAL item bank was produced using recommended procedures. At the second stage, Rasch analysis was performed to investigate its psychometric properties in 787 cataract patients (mean age, 58.2 years; mean ± SD visual acuity [logMAR], 1.19 ± 0.96 at baseline in eye for surgery) including comparison with the original version.
RESULTS Post-translation equivalence of meaning was achieved, but some English phrases required cross-cultural adaptation. Subsequently, all items were appropriate for the Indian culture, and VRAL item bank demonstrated excellent measurement precision (7.39). Dimensionality assessment suggested that VRAL construct may contain other dimensions such as self-care and visual search, and mobility. Self-care and visual search formed a unidimensional measure but was highly correlated with main VRAL dimension, and the removal of its items weakened precision of the main VRAL dimension measurement. Taken together, evidence favored retaining self-care and visual search items in a larger VRAL item bank. Mobility subscale lacked adequate measurement precision, so it was not examined further; again, items were retained in VRAL scale because they strengthened its measurement properties. Majority of items (99%) did not demonstrate notable differential item functioning (>1.0 logit) by presenting visual acuity (median, 0.20 logMAR) in the better-seeing eye.
CONCLUSIONS Items in the translated Indian VRAL item bank measure the same construct as the English version and fulfilled the psychometric requirements for use in cataract patients.Permalink : https://bibliotheque.helb-prigogine.be/opac_css/index.php?lvl=notice_display&id= [article]Exemplaires

[Thésaurus Mesh]Syndrome de rétraction de DuaneRésumé : SIGNIFICANCE The overall objective of this study was to evaluate facial asymmetry in patients with unilateral Duane retraction syndrome (DRS). The results showed a high frequency of facial asymmetry parameters of the opposite side of head turn in unilateral DRS patients.
PURPOSE The purposes of this study were to evaluate the characteristics of facial asymmetry in unilateral exotropic and esotropic DRS and to compare the findings with orthotropic subjects.
METHODS This cross-sectional comparative case series study was performed in 44 consecutive patients with head turn caused by DRS and 44 orthotropic subjects from 2016 to 2019. Four pictures were taken from the patients' faces. The first and second pictures were taken when patients had head turn and when the head was completely straight for calculating the facial angle and relative facial size, respectively. The third and fourth pictures were taken when the head was positioned downward (to compare the size of the cheek) and upward (to evaluate nose asymmetry).
RESULTS The mean ± SD age of DRS patients and orthotropic subjects was 16.23 ± 9.92 and 20.68 ± 11.82 years, respectively. The frequency of facial asymmetry and all facial parameters (cheek compression, nasal tip and columella deviation, and compression of one of the nostrils) was significantly higher in DRS patients compared with orthotropic subjects (P < .001). In DRS patients with facial asymmetry, columella and nasal tip deviation (P = .006) and cheek and face compression (P = .03) were significantly more prevalent in the opposite direction of head turn. In the DRS group, the mean ± SD age of the patients with and without facial asymmetry was 17.37 ± 9.76 and 7.40 ± 6.54 years, respectively (P = .02).
CONCLUSIONS The frequency of facial asymmetry and all facial parameters was significantly higher in DRS patients compared with orthotropic subjects. In unilateral DRS patients, the face was more commonly affected on the opposite side of head turn.Permalink : https://bibliotheque.helb-prigogine.be/opac_css/index.php?lvl=notice_display&id= [article]Exemplaires

PURPOSE This study was designed to evaluate changes in the office control score after office-based vergence/accommodative therapy for intermittent exotropia.
METHODS This was a prospective, unmasked pilot study. Fourteen Chinese participants aged 6 to 18 years with intermittent exotropia (excluding the convergence insufficiency type) were enrolled. All participants received 60 minutes of office-based vergence/accommodative therapy with home reinforcement once per week for 12 weeks. Therapy included vergence, accommodation, saccades and pursuits, antisuppression, and monocular fixation in binocular field techniques. The primary outcome measure was the change in the office control score from the baseline visit to the 13-week outcome visit.
RESULTS All participants completed the study. The office control score at distance changed by −1.0 (95% confidence interval [CI] = −1.6 to −0.4; P = .005; Cohen's d effect size, 0.93). The distant Look And Cover, then Ten seconds Observation Scale for Exotropia score and distant Newcastle control score total score changed by −0.7 (95% CI, −1.2 to −0.2; P = .02; Cohen's d effect size, 0.55) and −1.9 (95% CI, −2.8 to −1.0; P < .001; Cohen's d effect size, 1.37), respectively. Although there was no significant change in the angle of distance exodeviation (−1.8 prism diopter [Δ] less exodeviation; 95% CI, −3.74 to 0.14Δ; P = .11), a significant change was observed in the near angle (−4.4Δ less exodeviation; 95% CI, −7.3 to −1.5Δ; P = .01; Cohen's d effect size, 0.79). There was no significant change in stereopsis or the Chinese Intermittent Exotropia Questionnaire score.
CONCLUSIONS In this select group of children with intermittent exotropia, 12 weeks of office-based vergence/accommodative therapy with home reinforcement resulted in a statistically and clinically significant improvement in the distance control of exodeviation and the near exodeviation magnitude. These results suggest that there is a need for a randomized clinical trial designed to determine the effectiveness of vision therapy as a treatment modality for intermittent exotropia.Permalink : https://bibliotheque.helb-prigogine.be/opac_css/index.php?lvl=notice_display&id= [article]Exemplaires

[Thésaurus Mesh]Rétinopathie diabétiqueRésumé : SIGNIFICANCE Total protein concentration (TPC) and tumor necrosis factor α (TNF-α) concentration in tears are correlated with severity of retinopathy. However, minimal data are available in the literature for investigating tear TPC and TNF-α concentrations in Asian individuals with different severity of nonproliferative diabetic retinopathy (NPDR).
PURPOSE This study evaluated differences of TPC and TNF-α concentrations in tears at different severity of NPDR among participants with diabetes in comparison with normal participants.
METHODS A total of 75 participants were categorized based on Early Treatment for Diabetic Retinopathy Study scale, with 15 participants representing each group, namely, normal, diabetes without retinopathy, mild NPDR, moderate NPDR, and severe NPDR. All participants were screened using McMonnies questionnaire. Refraction was conducted subjectively. Visual acuity was measured using a LogMAR chart. Twenty-five microliters of basal tears was collected using glass capillary tubes. Total protein concentration and TNF-α concentrations were determined using Bradford assay and enzyme-linked immunosorbent assay, respectively.
RESULTS Mean ± SD age of participants (n = 75) was 57.88 ± 4.71 years, and participants scored equally in McMonnies questionnaire (P = .90). Mean visual acuity was significantly different in severe NPDR (P = .003). Mean tear TPC was significantly lower, and mean tear TNF-α concentration was significantly higher in moderate and severe NPDR (P < .001). Mean ± SD tear TPC and TNF-α concentrations for normal were 7.10 ± 1.53 and 1.39 ± 0.24 pg/mL; for diabetes without retinopathy, 6.37 ± 1.65 and 1.53 ± 0.27 pg/mL; for mild NPDR, 6.32 ± 2.05 and 1.60 ± 0.21 pg/mL; for moderate NPDR, 3.88 ± 1.38 and 1.99 ± 0.05 pg/mL; and for severe NPDR, 3.64 ± 1.26 and 2.21 ± 0.04 pg/mL, respectively. Tear TPC and TNF-α concentrations were significantly correlated (r = −0.50, P < .0001). Visual acuity was significantly correlated with tear TPC (r = −0.236, P = .04) and TNF-α concentrations (r = 0.432, P < .0001).
CONCLUSIONS This cross-sectional study identified differences in tear TPC and TNF-α concentrations with increasing severity of NPDR.Permalink : https://bibliotheque.helb-prigogine.be/opac_css/index.php?lvl=notice_display&id= [article]Exemplaires

[Thésaurus Mesh]Troubles de la visionMots-clés : contour contraste Résumé : SIGNIFICANCE Contour interaction describes an impairment of visual acuity produced by nearby flanking features, which exerts a significant impact in many clinical tests of visual acuity. Our results indicate that the magnitude of interaction depends either on the flanker contrast energy (i.e., the product of flanker contrast and width) or the flanker contrast alone, depending on the contrast energy of the flankers.
PURPOSE The discrimination of acuity targets is impaired by the presence of nearby flanking contours, a phenomenon known as contour interaction.
METHODS In this study, we measured percent correct identification for threshold size, high-contrast Sloan letters at the fovea and at 5° in the inferior visual field for different combinations of flanking-bar width, and Weber contrast corresponding to specific fixed values of contrast energy (width × contrast, in %-min arc).
RESULTS For flanking bars with low-contrast energy, contour interaction exhibited no systematic dependence on the flanking-bar width. However, when the flanking bars had higher contrast energy, narrower high-contrast bars produced significantly greater contour interaction than wider bars of lower contrast.
CONCLUSIONS The results are consistent with the interpretation that contour interaction depends primarily on the contrast energy of flanking contours when their contrast energy is low. As the contrast energy of the flanking contours increases, the magnitude of contour interaction depends on the flanker contrast. For high-contrast flanking contours, the magnitude of contour interaction saturates when the width of the flanking contours is approximately 20% of letter size.Permalink : https://bibliotheque.helb-prigogine.be/opac_css/index.php?lvl=notice_display&id= [article]Exemplaires
