[Thésaurus Mesh]Personnes malvoyantesRésumé : SIGNIFICANCE: Lighting assessments are an important component of low-vision rehabilitation but are rarely studied systematically. Our study indicates that preferred lighting levels support improvements in reading ease and enjoyment, independently of the evaluation technique. To determine preferred illumination level and color temperature, the LuxIQ is quicker to administer and covers broad options of settings. PURPOSE: The purpose of this study was to determine if preferred lighting, as assessed by the LuxIQ versus a standard lighting assessment, leads to better reading outcomes in individuals with low vision. METHODS: Preferred lighting was assessed at home with visually impaired persons (mean age, 75.3 years), using the LuxIQ (n = 18) or a standard technique based on trying out light bulbs of various intensity and color temperature (n = 16). Maximum reading speed and reading acuity were measured before the lighting intervention and then under the preferred lighting conditions. A 1-month telephone follow-up evaluated the (1) compliance with the lighting recommendations and, for those who modified their lighting, (2) their level of satisfaction with the length of reading time and eye strain felt during reading. RESULTS: Compared with usual lighting conditions, most participants preferred a cooler temperature at a higher illuminance level. Neither lighting assessment type appeared to lead to substantially improved objectively measurable reading outcomes. At the 1-month follow-up, 56% of the participants had modified their lighting, having a significant effect on satisfaction (P < .01), independent of assessment method. Of 18 respondents, 16 (87.5%) mentioned that reading was more enjoyable or easier with the lighting modifications. CONCLUSIONS: Both lighting assessment methods lead to comparable results, but the LuxIQ is easier and faster to use. More research is needed to determine whether the LuxIQ is suitable to be incorporated into clinical practice En ligne : https://journals.lww.com/optvissci/Fulltext/2020/04000/Comparison_of_Two_Lightin [...] Permalink : https://bibliotheque.helb-prigogine.be/opac_css/index.php?lvl=notice_display&id= [article]Exemplaires

Optometric education requires a sound financial plan to manage student debt. This study evaluates the financial inequalities of optometric programs in Canada and how this may impact the provision of eye care professionals. PURPOSE: The objective of this study was to compare the financial inequities in optometric education in Canada from the 2020 graduating class. METHODS: A cross-sectional study assessed monetary variables related to the study of optometry in Canada, including academic and personal expenses, and overall debt and expenses related to the COVID-19 lockdown for the 2020 graduating class. RESULTS: A total of 108 optometry students from the 2020 graduating classes of the University of Montreal and the University of Waterloo responded, with 68 (female/male respondents, 53:15; mean [standard deviation] age, 25.66 [2.01] years) completing the study. Waterloo students spent more years in university ( P < .001), had higher academic fees ( P < .001), spent more on traveling to their family residence (P = .007), and received more provincial ( P = .002) and federal ( P < .001) loans than Montreal students. Overall debt before optometry was similar among students but differed ( P < .001) at the end of their program, with Waterloo students having a higher debt burden. CONCLUSIONS: There is a financial inequity in optometric education in Canada depending on the chosen program. Cumulative optometry student debt for the 2020 graduating class in Canada ranges from Can $0 to $189,000 with an average of Can $65,800 and a median of Can $50,000. The results of this study can assist financial and government agencies, and future optometry students to better understand the financial burdens and establish a financial plan to study optometry in Canada, to respond to the growing eye care needs of the public.

[Thésaurus Mesh]Troubles de la visionRésumé : SIGNIFICANCE: Head-mounted low vision devices have become a viable alternative to enhance residual vision. This study supports the use of a head-mounted display to improve aspects of functional vision and quality of life. Much is still unknown regarding the required frequency, duration, or potential effectiveness of this telerehabilitation training protocol or what characteristics best identify optimal users. PURPOSE: A randomized study explored the effect of telerehabilitation on quality of life and functional vision in individuals with low vision using a head-mounted display. METHODS: We recruited 57 participants (age, 21 to 82 years; mean, 54.5 years) among new prospective eSight Eyewear users, randomized 1:1 into two parallel groups; the experimental group received the telerehabilitation training provided by a low vision therapist, whereas the control group received the self-training standard offered by the device manufacturer and without involvement of a low vision therapist. The primary outcome measures were the impact of telerehabilitation on validated measures of assistive technology–related quality of life: the Psychosocial Impact of Assistive Devices Scale and the Quebec User Evaluation of Satisfaction with Assistive Technology scale. Exploratory outcomes were the assessment of self-reported functional vision using the Veterans Affairs Low Vision Visual Functioning Questionnaire-48 and cybersickness associated with head-mounted display use with the Simulator Sickness Questionnaire. RESULTS: Assistive technology–related quality of life was improved when measured by the satisfaction scale but not the psychosocial scale within the first 3 months, independently of training type. Overall, functional vision improvement was observed within the first 2 weeks of device use and maintained during the 6-month study, independently of group type. Cybersickness outcomes were similar between training groups and did not change significantly for 6 months. CONCLUSIONS: eSight Eyewear, either with telerehabilitation or with the manufacturer self-training comparison, improved functional vision and increased users' quality of life within the initial 3 months of device training and practice.

[Thésaurus HELB]:Optique:basse visionRésumé : SIGNIFICANCE: The prevalence of dry eye disease and low vision increases with age; they share risk factors and
can be the result of underlying common causes. They are generally studied separately; however, combining these
perspectives is relevant for research on assistive technology given that sustained focus affects the tear film because
of decreased blinking rates.
PURPOSE: The objective of this study was to elucidate to which extent dry eye disease risk factors, signs, and
symptoms are assessed in low vision patients who receive an eye examination as part of their vision rehabilitation
services.
METHODS: Using a retrospective chart review, dry eye disease risk factors, signs, or symptoms were extracted from
201 randomly selected files that contained an eye examination in the past 5 years from two vision rehabilitation
centers.
RESULTS: Demographic variables of charts from the two sites did not differ (mean visual acuity, 0.85 logMAR
[standard deviation, 0.53; range, 0 to 2.3]; mean age, 71.2 years [standard deviation, 19 years; range, 24 to
101 years]). Fifty charts (25%) mentioned at least one dry eye disease symptom. Sixty-one charts (30.3%) reported systemic medications that can exacerbate dry eye disease, whereas 99 (49.2%) contained at least one systemic disease thought to contribute to dry eye disease symptoms; 145 (72.1%) mentioned at least one type of
ocular surgery. Artificial tears were documented in 74 charts (36.8%). Few specific dry eye tests were performed,
with the exception of corneal integrity assessment reported in 18 charts (8.95%).
CONCLUSIONS: Low vision patients have multiple risk factors for dry eye disease; however, dry eye disease tests
were not frequently performed in comprehensive low vision eye examinations in this sample. More efforts should be
made to assess dry eye disease to enhance comfort and functional vision, especially with the increasing demands
of digital devices as visual aids.Permalink : https://bibliotheque.helb-prigogine.be/opac_css/index.php?lvl=notice_display&id= [article]Exemplaires

[Thésaurus HELB]:Optique:basse visionMots-clés : vision résiduelle Téléréadaptation Résumé : SIGNIFICANCE: A recent trend in low vision rehabilitation has been the use of portable head-mounted displays to enhance residual vision. Our study confirms the feasibility of telerehabilitation and informs the development of evidence-based recommendations to improve telerehabilitation interventions to reduce device abandonment. PURPOSE: To develop evidence-based recommendations for telerehabilitation, we conducted a feasibility study in preparation for a future randomized trial on the use of head-mounted displays. METHODS: We recruited novice eSight Eyewear users, randomized 1:1: the experimental group received telerehabilitation by a low vision therapist using video conferencing; the control group completed at home self-training provided by the device manufacturer. The primary feasibility outcomes were whether the recruitment goal of 60 participants (30/group) was attainable within 1 year and how participants judged the accessibility and acceptability of the telerehabilitation. An exploratory outcome was the impact of telerehabilitation on eSight Eyewear use behavior. RESULTS: Among 333 eSight users, 57 participants were enrolled, of which 35% withdrew from the study, whereas the remainder completed the 6-month follow-up. The withdrawal rate was higher in the control group but did not differ significantly from the experimental group. High accessibility (93% of participants accessed the platform) and global acceptability (100% overall satisfaction) were reported among those who completed the telerehabilitation protocol. The therapist had no difficulty judging the participants' reading performances qualitatively while participants used their device to read their eSkills and VisExc guides. Most participants improved their daily activities, based on qualitative reports of the attained goals. Seventy-nine percent of individuals declined to participate, whereas 16% of participants decided not to use eSight Eyewear anymore. CONCLUSIONS: The data demonstrated the feasibility of a randomized controlled telerehabilitation study for people with low vision using a head-mounted display. Positive feedback from the participants and the therapist suggests the potential value of this modality for low vision services. Note de contenu :
