“…For those who cannot be helped through cataract surgery or the provision of spectacles, low vision services and magnification devices are important, but have tended to focus more on children and young people than older people (Kempen, Ranchor, Ambergen, & Zijlstra, 2014;Liu, Brost, Horton, Kenyon, & Mears, 2013). Simple home modifications, such as hand-rails and white stones to mark pathways, can reduce falls (Jones, 2013).…”

“…Patients with vision impairments similar to those who participated in this study have difficulties performing common everyday tasks such as reading, driving, and watching television. 30–33 Nevertheless, our subjects with CVL could differentiate blur from sharpness in the tested images. This is an important consideration in both designing image-enhancement devices and correcting refractive errors for patients with CVL.…”

PurposeThe long-term, low-resolution vision experienced by individuals affected by retinal disease that causes central vision loss (CVL) may change their perception of blur through adaptation. This study used a short-term adaptation paradigm to evaluate adaptation to blur and sharpness in patients with CVL.MethodsA variation of Webster's procedure was used to measure the point of subjective neutrality (PSN). The image that appeared normal after adaptation to each of seven blur and sharpness levels (PSN) was measured in 12 patients with CVL (20/60 to 20/320) and 5 subjects with normal sight (NS). Patients with CVL used a preferred retinal locus to view the images. Small control studies investigated the effects of long-term and medium-term (1 hour) defocus and diffusive blur.ResultsAdaptation was reliably measured in patients with CVL and in the peripheral vision of NS subjects. The shape of adaptation curves was similar in patients with CVL and both central and peripheral vision of NS subjects. No statistical correlations were found between adaptation and age, visual acuity, retinal eccentricity, or contrast sensitivity. Long-term blur experience by a non-CVL myopic participant caused a shift in the adaptation function. Conversely, medium-term adaptation did not cause a shift in the adaptation function.ConclusionsBlur and sharp short-term adaptation occurred in peripheral vision of normal and diseased retinas. In most patients with CVL, neither adaptation nor blur perception was affected by long-term attention to peripheral low-resolution vision. The impact of blur/sharp adaptation on the benefit of image enhancement techniques for patients with CVL is discussed.

Models of low vision care: past, present and future

Over the last 50 years, the concept of a low vision service has changed considerably. It has moved away from just the optometrist or optician dispensing magnifiers, to having a large team working across the health and social/ community care sectors, with voluntary organisations often playing an important role. This paper reviews how low vision rehabilitation services have evolved and what models of low vision care are currently available. It goes on to consider the effectiveness and accessibility of low vision care. Over the last 50 years, the focus of low vision care has moved from helping people with a visual impairment to read with magnifiers, to a holistic rehabilitation process involving a range of professionals.
