Introduction The aim of this study is to describe the barriers and facilitators to accessing low vision rehabilitation services in Massachusetts, USA, and determine differences between communities with and without existing low vision rehabilitation services for older adults with visual impairment. Method A sample of older adults with visual impairment ( n = 64) from both communities participated in the study. Barriers and facilitators to accessing the services were explored through focus groups and prioritized during one-on-one interviews, which allowed for comparison between communities. Results Twelve themes were identified: (a) bureaucracy and funding (public policy); (b) public awareness and stigma (community); (c) services available, knowledge of providers, care coordination, transportation (organizational); (d) people and lack of awareness of family/friends (interpersonal); and (e) income, health status, knowledge, self-advocacy, and time (individual). Conclusion This study provides insights into the perceived barriers and facilitators of accessing low vision rehabilitation services for older adults with vision impairment living in Massachusetts, USA. Key findings indicate the need for improved awareness of these services at the provider and consumer level, coordinated care, increased education on the efficacy of occupational therapy low vision rehabilitation services, client-centered care provided when the client is ready to accept services, and service provision that addresses sociodemographic factors.

Background: The present study is first of its kind to evaluate causes of visual impairment of blind students in Nepal and assess their need for low vision rehabilitation services. Aim: To evaluate causes of vision impairment of students enrolled in blind schools in Nepal and assess the need for low vision rehabilitation services in these students. Materials and methods: A survey was conducted in 12 blind schools in Nepal, which were registered with Nepal Association for Welfare of Blindness (NAWB).It was conducted by a team of an ophthalmologist and an optometrist, by using standard eye examination protocols of the World Health Organization Prevention of Blindness Program (WHO/ PBL). Results: Of the 345 students enrolled in 12 schools, 285 students were examined (response rate of 82.61%). The students were in the 5 - 29 years age group. Nearly three-fourth of the children had become blind within one year of age and 52.3% visually impaired at birth and 20.7% developed vision impairment within one year of age. After refraction, 26 students (9.12%) had mild visual impairment, 21 students (7.37%) had severe visual impairment and 238 students (83.51%) were blind. The main cause of vision impairment was found to be corneal 35.79% and retina diseases, mainly dystrophy, 20.35% followed by problems with the whole globe, lens and optic nerve, accounting for 13.33%, 12.63% and 12.98% respectively. The major etiological factors were those of childhood such as Vitamin A deficiency, measles and similar causes (42.11%) followed by hereditary causes (25.26%). Of the total students examined, 48.07% were visually impaired due to preventable causes and 16.14% treatable aggregating to 64.21% of avoidable blindness. Fifty seven (28.22%) students could read smaller than 2 M print size after low vision assessment for near and 33(15.78%) students benefited with telescopic trial for distance low vision. Conclusion: In Nepal, renewed focus on providing best possible quality of life for visually impaired children by proper low vision assessment and eye health education focusing on, general public and community health workers, with governmental and institutional support is required to achieve Vision 2020 objectives to decrease childhood blindness.

Although telescopic spectacles magnify the retinal image and should improve functional vision, many low vision patients are unable to use them. The authors found that involuntary head movements and the reduction of acuity with imposed head motion differentiated successful from unsuccessful telescope users and that success was related to the age at which telescopes were first used.

Background: Age-related macular degeneration (AMD) is the leading cause of loss of vision in the older age groups. In the absence of a known therapy, low vision rehabilitation aims at preserving residual functional vision at optimal levels. Long term functional outcomes from Low Vision Rehabilitation (LVR) in AMD cases were never scrutinized in the past. This study brings some clarification in this matter. Methods: This is a retrospective case series study including data up to 2 years following the baseline visit. Low Vision Assessments included microperimetry testing and recommendations for low vision devices for distance vision. Outcomes measures selected for this study were best corrected distance visual acuity, fixation stability and preferred retinal locus (PRL) topography and LVR interventions. Results: Data on 17 patients with an average age of 89.2 ± 4.4 years was collected. In those with better vision than 20/400 loss of vision was about 1.4 letter per year as tested with ETDRS charts compared with losses of four letters per year in a population without LVR interventions. Fixation stability continued to deteriorate while PRL eccentricity seemed to remain the same. In about half of cases there was a change in the topographic location of the PRL to a different retinal quadrant. Conclusion: Long term, as expected, changes were noticed in visual acuity, fixation stability and PRL topography. However, it seems that LVR interventions for distance vision help patients retain significantly better functional vision at the 2 years follow up interval when compared to others.

The Impact

Introduction The objective was to describe the occupational performance in basic and instrumental daily activities of persons living in the community who have received comprehensive interdisciplinary low vision rehabilitation services. Method The Mesure de l'impact de la déficience visuelle dans les activités quotidiennes (a measure of the impact of visual impairment in daily activities) was administered at home to 102 individuals who participated in a comprehensive low vision rehabilitation program. Performance in 16 near-vision activities was measured with the person's aids and strategies; nine more global tasks were questionnaire-based. Handicap scores were obtained by multiplying performance × importance ratings. Results Average performance was satisfactory or very satisfactory for 21/25 items, even if 92% of the participants had a moderate or severe visual impairment. A severe or total handicap was present in at least one activity for 79% of the subjects. The most handicapping activities required visual searches of finely printed information on a complex or visually crowded document, or shopping and mobility. Conclusion People with low vision who took part in a comprehensive rehabilitation program generally face no or slight handicap situations in their basic and instrumental daily activities. However, major handicap situations may remain in some important activities.

The goal of low vision rehabilitation is to produce people who are independent, have an economically viable profession or skill, and are able to enjoy their lives. Patients with hereditary retinal dystrophies are candidates for low vision rehabilitation from the time of diagnosis, since their disease shows a progressive course, there is no proven precise treatment and the disease especially seriously affects the vision of individuals of school age and productive age. The stages of modern low vision rehabilitation include the intake interview, assessment of residual visual functions, assessment of residual functional vision, interventions and recommendations, and vision rehabilitation therapies.

Visual Disturbances

Retinopathy of prematurity is one of the most important causes of blindness and low vision in childhood. In premature-born individuals, as well as retinopathy of prematurity, cerebral-induced visual disturbances are frequent and may result in low vision and blindness. In premature-born infants and children with or without retinopathy of prematurity, long-term eye and visual disturbances are more common than the term-born ones. Among these; myopia, refraction errors, strabismus, amblyopia, glaucoma, cataract, late retinal detachments, sensory and perceptual dysfunction, visual field defects, and cerebral visual disturbances can be seen. For this reason, life-long follow-ups of preterm born individuals are so important in terms of functional vision in the longterm.
