BACKGROUND: The purpose of low-vision rehabilitation is to allow people to resume or to continue to perform daily living tasks, with reading being one of the most important. This is achieved by providing appropriate optical devices and special training in the use of residual-vision and low-vision aids, which range from simple optical magnifiers to high-magnification video magnifiers. OBJECTIVES: To assess the effects of different visual reading aids for adults with low vision...

Perceptual learning (PL) has been traditionally thought of as highly specific to stimulus properties, task and retinotopic position. This view is being progressively challenged, with accumulating evidence that learning can generalize (transfer) across various parameters under certain conditions. For example, retinotopic specificity can be diminished when the proportion of easy to hard trials is high, such as when multiple short staircases, instead of a single long one, are used during training. To date, there is a paucity of mechanistic explanations of what conditions affect transfer of learning...

Introduction: It is important to monitor the use of optometric services by Veterans and consider the implications for other optometric and vision rehabilitation services. We did not find public health reports documenting the recent utilization of Veterans Health Administration (VHA) optometric eye exam services. Methods: A cross-sectional study design was used in this secondary data analysis report. We were interested in reporting on the number of Veterans using the VHA system with at least one VHA optometric eye exam service in 2014, 2015, or 2016 within a VHA optometry clinic...

Importance: The prevalence of irreversible vision impairment in the United States is expected to increase by 2050. Vision rehabilitation is the primary treatment option. Clinical trials have established its efficacy in improving quality of life. Yet studies indicate that patients experience many barriers to accessing low-vision care. Objectives: To examine the rate of referral for low-vision rehabilitation services by resident and attending ophthalmologists for adults with irreversible vision impairment and to assess the knowledge, attitudes, and beliefs of patients about vision rehabilitation...

BACKGROUND: Serious and often lasting vision impairments affect 30% to 35% of people following stroke. Vision may be considered the most important sense in humans, and even smaller permanent injuries can drastically reduce quality of life. Restoration of visual field impairments occur only to a small extent during the first month after brain damage, and therefore the time window for spontaneous improvements is limited. One month after brain injury causing visual impairment, patients usually will experience chronically impaired vision and the need for compensatory vision rehabilitation is substantial...

PURPOSE: This prospective cohort study examined clinical outcomes of low vision rehabilitation (LVR) delivered by a mobile clinic. METHODS: Participants were recruited from those scheduled for mobile clinic LVR and met the United States definition of legal blindness. Participants completed the Massof Activity Inventory (AI) before LVR, 3 months post-LVR, and 1 year post-LVR. Change scores and measures of clinical effect (i.e. Cohen's effect size and minimum clinically important difference, MCID) were calculated for each time point and compared...

Reading is the most frequent clinical complaint and the primary goal for patients with macular degeneration seeking vision rehabilitation. The current prevalent methods for reading skills training across the globe are still magnification and basic scotoma awareness training. More recent studies showed that specific eccentric training, comprehension ability training, and specific oculomotor training are all beneficial to reading skills rehabilitation. In clinical practice, ophthalmologists should strive to implement reading skills methods that include assessment of cognitive skills, optimal eyewear, optimal reading material, PRL assessment, training of better oculomotor control, and efficient perceptual training...

The Argus II retinal prosthesis is the first commercially available device for restoration of vision in patients with Retinitis Pigmentosa or with similar retinal pathology who still have minimal residual native vision. The technology is able to restore vision with production of artificial visual percepts which usually are given adequate useful interpretation by the visual system in most implanted patients. The technology usually produces visual perception at the level of shape identification or better in some cases enabling in many less dependence on vision substitution devices and skills...

Low vision is a condition caused by eye or brain disease, in which visual acuity is 20/70 (3/10 or 6/18) or poorer in the better-seeing eye and cannot be corrected or improved with regular eyeglasses. It impacts personal ability to perform vision-dependent tasks as activities of daily living, walking, reading or using a computer. Rehabilitation is a multidisciplinary training dedicated to improve patients' functional abilities and quality of life. It has to be personalized to every individual situation, whatever the underlying pathology...

INTRODUCTION: Because of the great potential of vascular endothelial growth factor inhibitors (anti-VEGF) for retinal exudative diseases, an increased number of patients receives this treatment. However, during this treatment, patients are subjected to frequent invasive intravitreal injections, and the effects on reversing the process of vision loss are uncertain, which may have negative consequences for patients' mental health. One in three patients experience at least mild symptoms of depression/anxiety...

The purpose of this research was to describe the strategies that older adults with low vision use to support daily living. A descriptive qualitative study of 10 older adults with low vision was conducted using semistructured, audio-recorded interviews. The data was coded and grouped into categories, and the findings were summarized. Four major themes were identified: (a) device nonuse; (b) sensory strategies and devices; (c) environmental strategies; and (d) resourcefulness. Older adults with low vision try many devices and strategies to find the ones that allow them to participate in meaningful activity within their physical and social environment...
