[Thésaurus Mesh]Hallux valgusMots-clés : capsulorraphie procedure range of motion, articular Hallux valgus comparative study Résumé : Background: Capsulorrhaphy restricts the motion of the first metatarsophalangeal joint (MTPJ) in hallux valgus surgery. However, changes in motion of the first MTPJ immediately after surgery that resulted from different capsulorrhaphy methods have not been compared. The primary aim of this study was to compare the immediate effect of Y-shaped and inverted L capsulorrhaphy methods on the range of motion (ROM) of the first MTPJ.
Methods: Y-shaped and inverted L capsulorrhaphies were performed on 16 human cadaveric feet. Passive dorsiflexion and plantarflexion of the first MTPJ were then compared preoperatively and postoperatively.
Results: In this cadaveric study, the inverted L capsulorrhaphy method led to a ROM loss in the first MTPJ; the joint stiffness from the Y-shaped capsulorrhaphy is significantly less than that from the inverted L capsulorrhaphy.
Conclusions: The inverted L capsulorrhaphy may lead to a ROM loss in the first MTPJ immediately after surgery. We recommend that surgeons close the capsule of the first MTPJ with a Y-shaped capsulorrhaphy, which is less likely to result in a ROM loss in the first MTPJ in the early postoperative period.Permalink : https://bibliotheque.helb-prigogine.be/opac_css/index.php?lvl=notice_display&id= [article]Exemplaires

[Thésaurus Mesh]OptométrieRésumé : SIGNIFICANCE
Validation of new biometry instruments against the gold standard and establishing repeatability are important before being utilized for clinical and research applications.
PURPOSE
This study aimed to investigate intersession repeatability of the MYAH optical biometer and corneal topographer and examine agreement with the Lenstar LS900 optical biometer in healthy young adults.
METHODS
Forty participants (mean age, 25.2 ± 3.1 years) presented for two visits, 2 to 4 days apart. At each visit, measurements for right eyes were collected with the MYAH and Lenstar LS 900 and included axial length, corneal power, white-to-white distance, and pupil diameter. Bland-Altman analysis was used to assess the intrasession agreement between the MYAH and Lenstar for each parameter and intersession repeatability for the two devices. For each device, coefficient of variation and intraclass correlation coefficient were calculated, and paired t tests between visits were performed to assess intersession repeatability.
RESULTS
Good agreement (mean difference [95% limits of agreement]) between the MYAH and Lenstar was found for axial length (−0.01 [−0.07 to 0.04] mm), corneal power (−0.02 D [−0.15 to 0.19 d]), white-to-white distance (−0.13 [−0.43 to 0.17] mm), and pupil diameter (−0.27 [−0.79 to 1.33] mm). The limits of agreement, coefficient of variations, and intraclass correlation coefficients for MYAH-measured parameters were −0.04 to 0.04, 0.06%, and >0.99 for axial length; −0.24 to 0.19, 0.18%, and >0.99 for corneal power; −1.05 to 1.15, 0.57%, and 0.96 for white-to-white distance; and −0.17 to 0.21, 7.0%, and 0.76 for pupil diameter, with no significant difference between visits (p>0.05 for all), indicating good intersession repeatability. Similar intersession repeatability was also noted for Lenstar.
CONCLUSIONS
Findings show good intersession repeatability of the MYAH and good agreement with the Lenstar for axial length, corneal power, and white-to-white distance in young adults. Pupil diameter was more variable, likely due to the dynamic nature of the pupil. This study provides validation and supports the use of the MYAH for ocular biometry.Permalink : https://bibliotheque.helb-prigogine.be/opac_css/index.php?lvl=notice_display&id= [article]Exemplaires

[Thésaurus Mesh]ViscositéRésumé : SIGNIFICANCE: Rheological patterns were objectively calculated considering the first and last viscosity, besides the difference of viscosity with a specific shear rate. Shear thinning, shear thickening, thixotropic, and Newtonian behavior patterns were found.
PURPOSE: This study aimed to describe, in an objective way, the heological behavior of several artificial tears.
METHODS: Seventy-eight artificial tears were included in this experimental analytical study. Its viscous behavior was measured using a cone-plate rheometer. An ascending and descending measurement range was defined for the shear rate from 1 to 1000 s−1 and vice versa. Hysteresis was alculated with the initial and final difference of viscosity. The rheological behavior pattern was calculated as the viscosity difference for the shear rate between 100 and 1000 s−1 .
RESULTS: Four rheological patterns with different magnitudes were found: shear thinning, shear thickening, thixotropic, and Newtonian.
CONCLUSIONS: The viscosity of artificial tears always depends on the shear rate. It is possible to find two patterns simultaneously depending on the shear rate. These rheological patterns could serve to optimize the treatment with lubricants for different conditions of the ocular surface. In vivo studies are necessary to evaluate the clinical significance of these findings.Note de contenu :

[Thésaurus HELB]:Paramédical:film lacrymalMots-clés : vidéokératoscope Résumé : SIGNIFICANCE: While evaluating the tear-film breakup time, a careful set of precise instructions should be given to the subjects regarding the blink type because it substantially impacts the assessment of tear-film surface quality. PURPOSE: The purpose of this study was to determine to what extent the type of blink affects the tear-film breakup time and its assessment using two types of videokeratoscopes and the fluorescein test. METHODS: Thirty-three volunteers were assessed considering two different types of blinks: natural (short) and forced (unnaturally prolonged). Objective noninvasive breakup time estimation was performed using Oculus Keratograph 5M and Medmont E300, both equipped with tear-film analysis modules, followed by the fluorescein test. In addition, while overviewing videokeratoscopy recordings, noninvasive breakup time was assessed subjectively by one experienced observer marking the first noticeable distortion in the Placido-disk pattern. Statistical analyses included two-way ANOVA and paired-sample t test. The agreement between blinking and measuring modalities was assessed using Bland-Altman plots. RESULTS: Forced blink significantly shortened the tear-film breakup time in all measuring modalities (two-way ANOVA, P = .003). The mean difference between breakup time after natural and forced blink was 3.2 (P = .002), 2.4 (P = .005), and 2.1 seconds (P = .002), for Keratograph 5M, E300, and fluorescein test, respectively. The group median of differences between objective and subjective noninvasive breakup time was less than 1 second with both videokeratoscopes. The objective noninvasive breakup time measured with Keratograph 5M was significantly longer than those with E300 and fluorescein test (both P < .001). No statistically significant difference was found between E300 objective assessment and fluorescein test (P = .19). CONCLUSIONS: Forced blinks affect the assessment of tear-film stability. Hence, attention should be given in instructing the subjects before tear-film breakup time evaluation irrespectively to the method of measurement.

[Thésaurus HELB]:Optique:basse vision
[Thésaurus HELB]:Optique:loupeMots-clés : distance entre la lentille de la loupe et la surface de l'image divergence Résumé : SIGNIFICANCE: Low vision rehabilitation clinicians must sometimes evaluate stand magnifiers to determine their true optical properties. A novel method is described for measuring the image distance of stand magnifiers. PURPOSE: We describe a new method for determining the image distance of stand magnifiers, which has some advantages over previously described methods. METHODS: Diverging light emerging from a stand magnifier is brought to a focus on the ceiling or other flat surface using convex lenses placed on the top of the stand magnifier lens. Knowing the power of this convex lens and the distance from the magnifier lens to the imaging surface, one can calculate the degree to which the emerging light is diverging and, from that, the image distance. Each author evaluated three stand magnifiers using this method and compared our results with each other and with the values for image distance published by the manufacturer. RESULTS: Our method produced measurements that were consistent between three clinicians, with emerging divergence values differing by no more than 0.37 D and image distance differing by 0.6 to 3.1 cm for the three magnifiers evaluated. Our measured values also corresponded favorably with the published image distances listed in the manufacturer's catalog, deviating by a maximum of 3.7 cm and a mean of 1.3 cm. When the manufacturer's image distances were converted to dioptric divergence, our measurements varied by a maximum of 0.48 D and a mean of 0.17 D. CONCLUSIONS: Our method provides an expedient and clinically accurate way to evaluate the divergence and image distance of a stand magnifier. Knowing the image distance is valuable by itself, but the divergence of the emerging light is also critical in determining the stand magnifier's enlargement ratio.
