Études croisées
Studies comparing two or more treatments or interventions in which the subjects or patients, upon completion of the course of one treatment, are switched to another. In the case of two treatments, A and B, half the subjects are randomly allocated to receive these in the order A, B and half to receive them in the order B, A. A criticism of this design is that effects of the first treatment may carry over into the period when the second is given. (Last, A Dictionary of Epidemiology, 2d ed)

[Thésaurus Mesh]Vision faibleMots-clés : test de Freiburg test de Berkeley Résumé : SIGNIFICANCE Well-established charts such as Early Treatment Diabetic Retinopathy Study are able to quantify visual acuity (VA) with a low cutoff of 1.6 logMAR. Below this point, nonquantitative measures, such as count fingers, hand movements, and light perception, are used. There is a need for more reproducible, comparable, and reliable ways to measure VA changes in this patient cohort.
PURPOSE The purpose of this study was to examine and compare the ability of the Berkeley Rudimentary Vision Test (BRVT) and the Freiburg Acuity Test (FrACT) to quantify VA in low-vision patients who score nonnumerical VAs in standard charts.
METHODS Fifty adult participants with VA ≤1.0 logMAR in both eyes were recruited from the Oxford Eye Hospital, Oxford, United Kingdom. Correlation between FrACT and BRVT results and the correlation between VA and daily living activities were analyzed statistically. Potential predictors of differences were investigated.
RESULTS The BRVT was significantly faster to conduct (P = .002), but FrACT was able to quantify vision numerically in a greater proportion of eyes. The κ agreement between tests was 0.26. The difference increased systematically with the VA reduction (P < .0001). The Bland-Altman analysis showed a skew to measurement of lower logMAR VA indicating better vision measured on the FrACT. The only significant predictor of difference between the tests was binocular VA (coefficient, −0.445; P = .001).
CONCLUSIONS Both tests are suitable for a very low-vision population. The BRVT is a faster test to administer, but FrACT provides a numerical result in more eyes. The poor intertest repeatability indicates that they cannot be used interchangeably. The BRVT generally reported poorer vision than did the FrACT. The medium of presentation, such as a computer screen or externally lit print medium, is likely to be the biggest factor in these differences and warrants further investigation.Permalink : https://bibliotheque.helb-prigogine.be/opac_css/index.php?lvl=notice_display&id= [article]Exemplaires

[Thésaurus HELB]:Optique:lentille photochromiqueMots-clés : automobile driving cross-over studies contact lenses additif photochromique vision, ocular Résumé : SIGNIFICANCE: The first contact lens to incorporate a photochromic additive was cleared by the U.S. Food and
Drug Administration last year. Because any ophthalmic lens that absorbs visible wavelengths will reduce retinal illuminance, it is important to understand the impact of this new photochromic contact lens on vision and both daytime and nighttime driving performance.
PURPOSE: The purpose of this study was to evaluate the effect of senofilcon A photochromic contact lens wear on
vision and driving performance under real-world conditions by comparison with a nonphotochromic contact lens
and plano photochromic spectacles.
METHODS: In this randomized four-visit bilateral crossover study, 24 licensed regular drivers and established
wearers of soft contact lenses were enrolled. Subjects wore in random order each of three study lens types: the investigational photochromic soft contact lens (test), a nonphotochromic soft contact lens (control 1), and plano photochromic spectacle lenses (control 2). Driver performance was assessed on a closed-circuit driving track under
challenging controlled conditions. The primary endpoint was overall driving performance score calculated as a
composite Z score of six objective metrics.
RESULTS: All 24 subjects (mean age, 29.8 years) completed the study. For nighttime driving, the adjusted mean
differences in Z score (95% confidence interval) between test and control 1 and between test and control 2 were
0.069 (−0.045 to +0.183) and 0.117 (0.003 to 0.231), respectively. For daytime driving, mean differences were
0.101 (−0.013 to +0.216) between test and control 1 and 0.044 (−0.070 to +0.158) between test and control 2.
Results demonstrated noninferiority of the test lens relative to controls for nighttime and daytime driving performance using a noninferiority margin of −0.25 Z score. Noninferiority was also demonstrated on all logMAR and
contrast threshold testing. No adverse events were reported during the study.
CONCLUSIONS: Study results revealed no evidence of concerns with either driving performance or vision while
wearing photochromic contact lensesPermalink : https://bibliotheque.helb-prigogine.be/opac_css/index.php?lvl=notice_display&id= [article]Exemplaires

[Thésaurus Mesh]Vision oculaireMots-clés : lentilles de contact multifocales (MFCL) Résumé : SIGNIFICANCE
During computer work in controlled laboratory conditions, wearing multifocal contact lenses (MFCLs) showed no lower muscle load but increased subjective perception of comfort with equivalent visual quality and comparable tolerance.
PURPOSE
Because musculoskeletal complaints are frequent among computer workers, this study used the muscle electrophysiological activity of shoulder and neck muscles in presbyopic computer workers who received either progressive addition lenses for general purpose (GP-PALs) or MFCLs.
METHODS
For this crossover study, 11 presbyopic computer workers aged 55 ± 4 years (mean ± standard deviation) were equipped with GP-PALs and MFCLs in a randomized order. Surface electromyography signals were recorded bilaterally from shoulder and neck muscles during short-term computer work tasks using an optimally adjusted visual display unit workplace. The amplitude probability distribution function, the number and total duration of EMG gaps, and sustained low-level muscle activity periods of the surface electromyography signals were calculated. Comfort and correction type preferences were assessed. Head inclination was objectively evaluated.
RESULTS
Multifocal contact lenses elicited no significant lower muscle load than GP-PALs. The number of sustained low-level muscle activity periods longer than 60 seconds was similar between visual aids. The total amount of gaps was significantly higher with MFCLs (44 gaps) compared with progressive addition lenses for general purpose (15 gaps) in all analyzed periods for all participants. However, there were no significant differences for the median in the intraindividual comparisons (P = .22, dz = 0.52). Multifocal contact lenses scored statistically significant higher in comfort values with equivalent visual quality and comparable tolerance (P = .003, dz = 1.51).
CONCLUSIONS
Although the study failed to show clear results, wearing MFCLs seems to enhance working comfort compared with GP-PALs subjectively.Permalink : https://bibliotheque.helb-prigogine.be/opac_css/index.php?lvl=notice_display&id= [article]Exemplaires
