“…This study showed that through the provision of individually fitted low vision aids, near and distance visual acuity could be improved, leading to patients regaining the ability to read, which was in line with the findings of other studies [13][14][15][16]. Not only visual acuity but also reading speed can be improved through low vision aids, which Ngyuen et al ( 2008)-as well as other studies, such as refs.…”

“…However, conventional electronic aids such as CCTV (closed circuit television) in this study were most commonly fitted in the age group of patients who were 60 years and older, showing that age and social stigmata (e.g., older patients not being able to cope as easily with handling electronic devices as children and adolescents) should not play a role in the fitting of low vision aids. Proper fitting and advice and training in handling a fitted aid, on the other hand, are important parts of low vision services [15]. This statement is further supported through the high amount of adaptive care that patients received in this study population, again emphasizing the need for low vision services.…”

(1) Background: This study aims to highlight differences in the etiology and fitting of low vision aids in visually impaired children and adolescents in comparison to adults. (2) Methods: A retrospective data collection from visually impaired patients presenting to obtain assistive devices from 1 January 2016 to 30 April 2020 was conducted. A total of 502 patients were included. Inclusion criteria were a minimum age of 4 years and the chart notation of a best-corrected distance visual acuity in the patient record prior to the fitting of magnifying visual aids. (3) Results: Of the 502 patients, 147 (29.3%) were children under the age of 18 years. The most common cause of visual impairment in children was albinism, and in adults, it was age-related macular degeneration (AMD). Children showed better distance visual acuity, with a median of 0.88 logMAR (Logarithm of the Minimum Angle of Resolution) compared to 1.0 in adults (p = 0.001). Near visual acuity was also significantly better, with a median of 0.54 logMAR in children compared to 0.9 in adults (p < 0.001). Near and distance visual acuity were significantly improved by fitting magnifying visual aids (p < 0.001). After fitting, near visual acuity averaged 0.3 logMAR, and distance visual acuity, 0.7. The most commonly prescribed aids were optical vision aids, which 68.5% of the patients received; 43.8% received electronic aids. In children, optical aids were more frequently prescribed, and in adults, electronic and acoustic aids (p < 0.001). (4) Conclusion: Visually impaired patients can regain the ability to read and improve distance vision by using individually adapted and tested magnifying vision aids, often with optical aids alone. Differences between children and adults could be discovered in the etiology and severity of visual impairment, as well as in the provision type of low vision aids.

A baixa visão é uma condição caracterizada pelo comprometimento visual mesmo após tratamento ou correção médica, gerando diversos impactos na vida dos indivíduos. Diante disso, a utilização de dispositivos auxiliares é fundamental para mitigar os efeitos da perda visual. Entre os diversos auxílios ópticos disponíveis atualmente, a maior parte ainda apresenta um custo elevado, o que dificulta a sua aquisição pelos pacientes. O presente trabalho teve como propósito a criação de um dispositivo óptico vestível para baixa visão, utilizando tecnologias de impressão 3D com baixo custo final. Foi realizado um estudo descritivo do tipo experimental, dividido em 7 etapas: Ideação e criação, Modelagem 3D, Impressão 3D das peças estruturais, Desenvolvimento de aplicativo próprio, Montagem, Testes e Calibração. Durante as 3 primeiras etapas criamos um suporte de cabeça para receber um smartphone e um módulo de captura e transmissão de imagens. Em seguida, foi desenvolvido um aplicativo que enviasse as imagens do módulo ao smartphone. Por fim, foi realizada a calibração do conjunto com um voluntário com baixa visão. Foi desenvolvido um dispositivo óptico vestível funcional na forma de MVP (Minimum Viable Product) que passou por testes e alguns ajustes de funcionalidade. O trabalho resultou na criação de um MVP que está sujeito a modificações industriais para seu aperfeiçoamento. No entanto, o processo de validação do dispositivo para a utilização por sujeitos de baixa visão já está em andamento pelos autores do trabalho..

Purpose:The aim of this study is to elucidate the causes and level of visual impairment (VI) in patients with different pathologies of diabetic retinopathy (DR) who presented to a low vision care (LVC) clinic, to analyze the type of distant and near devices prescribed to them and the visual benefits thereof.Methods:A retrospective chart review was done for 100 consecutive patients with DR who were referred to the LVC clinic from June 2015 to June 2016. The reason for referral was assessed from the electronic medical records and available fundus photographs, fundus fluorescein angiograms, and optical coherence tomography images by a retina specialist. The details of low-vision devices and subsequent improvements were noted.Results:Of the 100 patients, 52% had moderate VI, 19% mild VI, 16% severe VI, and 13% had profound VI or blindness. The most commonly prescribed low vision device was half-eye spectacles (38.4%). The pathologies which had statistically significant improvement (P < 0.05) in distance vision with low vision devices were DR with disc pallor (4.4% improvement), ischemic maculopathy (11.9% improvement), and plaque of hard exudate (10.1% improvement). However, in all pathologies, there was statistically significant improvement (P < 0.05) in near vision.Conclusion:Usually, the patients with DR presented to the LVC clinic with moderate VI. The use of low vision devices can help these patients in cases where medical and surgical treatment have no or a limited role in restoring useful vision.
