Myopie
A refractive error in which rays of light entering the EYE parallel to the optic axis are brought to a focus in front of the RETINA when accommodation (ACCOMMODATION, OCULAR) is relaxed. This results from an overly curved CORNEA or from the eyeball being too long from front to back. It is also called nearsightedness.

[Thésaurus HELB]:Paramédical:recherche médicaleRésumé : SIGNIFICANCE
Popularity of publicly searched myopia terminologies is reported, for example, myopia control over myopia management and myopia over nearsighted or shortsighted. Insights are also provided for searches on specific myopia control interventions. The findings offer an evidence-based starting point for public messaging and communications by clinicians, policymakers, and other industry leaders.
PURPOSE
Public understanding of myopia can be difficult to ascertain for clinicians. Although small-scale studies provide valuable snapshots of data, findings tend to be population-specific and thus difficult to extrapolate to global audiences. In this study, big data were used to provide a more comprehensive depiction of global market interest in myopia.
METHODS
Google Trends data were used to analyze searches relating to myopia between January 2004 and August 2023. Data extracted were related to use of the terms myopia control and myopia management, with further searches executed for common myopia control interventions: orthokeratology, contact lenses, atropine, and glasses. Analysis into the search interest of other refractive error states, hyperopia and astigmatism, was also undertaken along with alternative terms that may be used to describe myopia. Where relevant, search trends were considered worldwide, by country, and over time.
RESULTS
Myopia was a more popular search term than common layman alternatives such as nearsighted or shortsighted. Myopia control was found to be more popular than myopia management, and of the specific myopia interventions, atropine was most popular. Compared with astigmatism and hyperopia, relative search volumes were greatest for myopia, on average accounting for approximately 50% of the relative search volume at the country level.
CONCLUSIONS
The differences identified in both popularity of myopia-related search terms and specific interventions may provide the basis for improvements in public messaging and facilitate patient-practitioner communication.Permalink : https://bibliotheque.helb-prigogine.be/opac_css/index.php?lvl=notice_display&id= [article]Exemplaires

[Thésaurus Mesh]OptométrieRésumé : SIGNIFICANCE
Multiple vision-related quality of life (VRQol) instruments exist, but questionnaires designed specifically for myopic children that are appropriate for assessing the impact of refractive error are rare.
PURPOSE
This study aimed to assess the validity and reliability of the Student Refractive Error and Eyeglasses Questionnaire – Revised (SREEQ-R) in school-aged children with myopia in the United Kingdom.
METHODS
Community optometrists in the United Kingdom invited children up to the age of 18 years presenting for an eye examination with current or previous reported use of eyeglasses for myopia to complete the SREEQ-R, which consists of 20 specific items divided into two sections each with three response categories. The “without glasses” section relates to perceptions of uncorrected vision/not wearing glasses, and the “with glasses” relates to corrected vision/wearing glasses. Rasch analysis was used to explore the psychometric performance (content, construct validity, and reliability) of the questionnaire items and scale using Winsteps software (Winsteps.com. Portland, OR).
RESULTS
A total of 125 eligible children with a mean ± standard deviation age of 12.7 ± 2.9 years completed the SREEQ-R. All items fit the Rasch model and were retained, and the scale was found to be unidimensional. All children and item infit and outfit mean square statistics fell within the recommended fit criteria. As per the Rasch analysis, the person reliability coefficients were 0.84 and 0.91, whereas item reliabilities were 0.99 and 0.80 for the without glasses and with glasses sections, respectively. The internal consistency for the SREEQ-R was good; Cronbach α values were 0.84 for without glasses and 0.91 for with glasses.
CONCLUSIONS
The SREEQ-R had satisfactory validity and reliability evidence. Construct validity of the scale was supported to measure the impact of uncorrected and corrected refractive error on vision-related quality of life in myopic school-aged children in the United Kingdom. The SREEQ-R could be used in future studies to evaluate vision-related quality of life in children with myopia.Permalink : https://bibliotheque.helb-prigogine.be/opac_css/index.php?lvl=notice_display&id= [article]Exemplaires

[Thésaurus Mesh]Vision oculaireRésumé : SIGNIFICANCE: Visual performance is affected least by a 15° radial aperture surrounded by peripheral myopic defocus. This finding has important applications for spectacle and contact lens designs and myopia control optimization. PURPOSE: The purpose of this study was to assess the effect of clear central apertures of different diameters with a defocused retinal periphery, using a range of visual performance tasks. METHODS: Thirty visually normal subjects (mean age, 24.4 ± 3.3 years; 20 females; mean spherical equivalent of −1.28 D) were enrolled. Subjects wore five different spectacles during testing, all corrected for distance refraction, in random order: three single-vision spectacles with clear central apertures of 10, 12.5, and 15° radii with the periphery defocused using Fresnel “press-on” lenses (+3.5 D sphere), progressive addition lens (PAL) spectacles with a +3.5 D addition, and single-vision lens (SVL) spectacles with no peripheral defocus. Static and kinetic visual field sensitivities, reading rate and comprehension, head movements, global saccadic tracking, and saccadic visual search were evaluated. RESULTS: Reading rate and comprehension did not differ across the five test conditions; however, increased head movement was found with the smallest aperture compared with the PAL condition with adjusted P < .05. Static visual field sensitivity was reduced for all three apertures in eccentric regions when compared with the SVL and PAL conditions with adjusted P < .05, whereas kinetic sensitivity did not differ for any lens condition. The 15° aperture was superior to the 10 and 12.5° apertures based on its similarity to the SVL and PAL spectacle conditions in head movement during reading, the Michigan Tracking Test, and the vertical results of the Developmental Eye Movement Test. CONCLUSIONS: Visual performance is least affected adversely by a 15° aperture surrounded by a peripheral myopic defocus. This finding has important applications for spectacle and contact lens designs to optimize myopia treatment with minimal impact on visual performance.

[Thésaurus HELB]:Optique:Lentilles multifocalesRésumé : SIGNIFICANCE: With multifocal contact lenses (MFCLs) used for myopia control, questions remain regarding visual performance. Information from nonpresbyopic patients provides insight into how MFCLs affect visual acuity
and reading performance.
PURPOSE: The purpose of this study was to examine the visual performance of center-distance MFCLs in
nonpresbyopic adults under different illumination and contrast conditions compared with a single-vision contact
lens (SVCL).
METHODS: Twenty-five adult subjects were fit with three different lenses (CooperVision Biofinity D MFCL +2.50
add, Visioneering Technologies NaturalVue MFCL, CooperVision Biofinity sphere). Acuity and reading performance
were evaluated.
RESULTS: A statistically significant difference in high-contrast distance acuity was observed (Biofinity, −0.18 ± 0.06;
Biofinity MFCL, −0.14 ± 0.08; NaturalVue MFCL, −0.15 ± 0.03; repeated-measures [RM] ANOVA, P = .02). Under
mesopic, high-contrast conditions, MFCLs performed worse than SVCLs (Biofinity, −0.05 ± 0.091; Biofinity MFCL,
+0.03 ± 0.09; NaturalVue MFCL, +0.05 ± 0.091; RM-ANOVA, P < .0001). Under low-contrast conditions, MFCLs performed one line worse in photopic lighting and two lines worse under mesopic conditions (RM-ANOVA, P < .0001).
Glare reduced acuity by 0.5 logMAR for all lenses (RM-ANOVA, P < .001). A statistically significant difference in near
acuity was observed (RM-ANOVA, P = .02), but all lenses achieved acuity better than −0.1 logMAR (Biofinity,
−0.16 ± 0.06; Biofinity MFCL, −0.17 ± 0.04; NaturalVue MFCL, −0.13 ± 0.08). Reading performance in words per
minute (wpm) was worse with MFCLs (Biofinity MFCL, 144 ± 22 wpm; NaturalVue MFCL, 150 ± 28 wpm) than with
SVCLs (156 ± 23 wpm; RM-ANOVA, P = .02) regardless of letter size (RM-ANOVA, P = .13). No difference in acuity
between the MFCLs was detected (RM-ANOVA: all, P > .05).
CONCLUSIONS: Multifocal contact lenses perform similarly to SVCLs for high-contrast targets and display reduced
low-contrast acuity and reading speed. Practitioners should recognize that high-contrast acuity alone does not describe MFCL visual performance.

PURPOSE: This study aimed to determine the maximum add power children wearing center-distance soft multifocal contact lenses could accept objectively and subjectively. METHODS: Myopic children were assigned in random order to wear omafilcon A single-vision or multifocal “D” contact lenses with +2.00, +3.00, or +4.00 D add power for 1 week each. High-contrast distance and near visual acuity, low-contrast distance visual acuity, and contrast sensitivity were measured at each visit along with a quality of vision questionnaire to assess their vision. The Friedman test was performed to evaluate the impact of add power on all outcome measures. Results: Eleven subjects were enrolled, and nine subjects completed the study. The median age of completed subjects was 11 years. Median logMAR low-contrast distance visual acuity was reduced in the +3.00 (+0.20) and +4.00 (+0.28) D add lenses compared with the +2.00 (+0.16) D add and single-vision lenses (+0.10, P < .001). All three multifocal lenses resulted in reduced contrast sensitivity (+1.35 to +1.40) compared with single-vision lenses (+1.60, P < .001). In general, +3.00 and +4.00 D add lenses resulted in worse glare/ starbursts, ghost images, computer vision, changing fixation distance, and overall vision, but results varied. There were no differences among the lenses with respect to subjective assessments of distance vision, near vision, strain or tiredness, contact lens comfort, or sporting activities. CONCLUSIONS: The +3.00 D and higher add powers result in more objective and subjective vision-related issues than single-vision lenses, but the +2.00 D add multifocal lenses were well tolerated Permalink : https://bibliotheque.helb-prigogine.be/opac_css/index.php?lvl=notice_display&id= [article]Exemplaires
