Use of electronic devices by people attending vision rehabilitation services in Italy: A study based on the device and aids registry (D.A.Re).

PURPOSE: To investigate the characteristics of electronic device users, specifically smartphones and tablets, in the Device & Aids Register (D.A.Re), from several low-vision rehabilitation services in Italy. METHODS: We collected general and clinical information about ocular and systemic diseases, visual function, reading speed and Instrumental Activities of Daily Living (IADL) questionnaire score. Technological details of each optical and electronic device, (including screen size, touch-screen and OCR functions, text-to-speech function) were also collected. RESULTS: 1218 patients (752 females and 466 males) were included in our analysis, mean age 71.5 (±18.8) years. Users of electronic aids (n.237) were slightly younger (67 vs 72 years, p < 0.001) than non-users (n.981), had a worse reading speed (38 vs 65 words/minute), critical print size (43 vs 28 print size, p < 0.001), poorer visual acuity (VA)(1.0 logMAR or less: 30% non-users vs 73% users, p < 0.001) and more commonly visual field restriction within 10° (23% vs 14%, p = 0.001). A similar proportion of users and non-users were retired (about 70%) and about 16-17% were employed. The use of portable electronic devices (5″or less, p < 0.001; 6″ to 18″ screen size, p = 0.017) was associated with better IADL scores, and the use of stand devices with worse IADL score (p < 0.001); Furthermore, using smartphones and tablets (193 subjects) was strongly associated with better IADL scores. CONCLUSION: We found that using electronic devices, and especially smartphone and tablets, were associated with better vision-related quality of life in low-vision people attending rehabilitation services. While this association does not mean causality, these findings seemed robust to confounder adjustment.

Low-vision rehabilitation in Italy: Cross-sectional data from the Device and Aids Registry (D.A.Re).

OBJECTIVES: We are reporting on the characteristics of low-vision adults attending large rehabilitation services which provide data to D.A.Re (Devices & Aids REgister) in Italy. D.A.Re aims to gather information about low-vision aids owned by Italian patients with visual impairment. METHODS: We included consecutive patients attending low-vision rehabilitation centres providing data to D.A.Re from 2019 to July 2021. Demographic features, self-reported use of technology and aids, vision performance, and the Instrumental Activity of Daily Living (IADL) score were collected. RESULTS: 720 patients were included in the D.A.Re. About half of the patients were affected by Age-related Macular Degeneration (389, 54.9%). Patients reported a long interval between onset of vision disability and access to low-vision rehabilitation, which was over two years in almost 30% of cases. Blindness registration status was almost complete when reported, but almost 40% were unable to report on this. IADL scores were higher for younger people and those with better visual acuity and critical print size (CPS), and lower for visual field restriction (p < 0.01 for all predictors). Of interest, better IADL scores were recorded for those with computer knowledge who used optical aids and software in univariate analyses and multivariate analyses, adjusting for level of visual disability and employment status (p < 0.01 for all predictors). CONCLUSIONS: We report on the profile of low-vision patients using rehabilitation services in Italy. Longitudinal data during and after vision rehabilitation were collected. Our results support the validity of the D.A.Re to monitor the use of low-vision devices in Italy.
