REFRAMING AGING AND VISION LOSS AS A PUBLIC HEALTH IMPERATIVE

Abstract Severe vision impairment and blindness often have profound effects upon older people and those who care for and about them. Recent translational research reveals in the United States, 7.3% of older people report severe vision impairment or blindness. A recent study estimated that the population of people with vision impairment will increase by 118% by 2050. The greatest increases will be among the most senior, women, African Americans, and Hispanics. People with vision impairment report greater prevalence of chronic conditions, poorer health, and poorer quality of life than older people without vision impairment, and they are much more likely to experience multiple disabilities. These factors point to grave disparities in health equity. While the multiple studies have informed social, health, and economic disparities among older people with vision impairment at the national level, virtually nothing is known about the variability of the prevalence of vision impairment, chronic conditions, health-related quality of life, and disability at the state level. The geographic distribution of vision impairment varies among and within states. Often rural and poorer areas have a higher prevalence of vision impairment — areas that generally have a paucity of eye care providers, social support systems, and vision rehabilitation services. As aging issues are addressed at state and federal levels, vision loss and vision rehabilitation are frequently omitted from the conversations and plans (e.g., Master Plans on Aging and/or Age-Friendly Plans) and from policy instruments such as the Older Americans Act, which has no mention of vision or vision loss.

Family perceptions and barriers towards rehabilitation of visually disabled people: A qualitative survey from Western Uttar Pradesh

Looking at the number of visually disabled people population of Uttar Pradesh, there has been a paucity of evidence available on their perception and rehabilitation. This study was conducted to explore the perceptions and possible barriers to the uptake of visual rehabilitation services among visually disabled patients and their families in western Uttar Pradesh.A qualitative investigation using one-to-one interviews with the convenience sampling method in the subjects severely visually disabled (Blind) participants, and their family members. The unstructured interviews were conducted by an independent interviewer. All the interviews were conducted in Hindi. The anonymous quotes of transcripts were translated into English for reporting purposes.A total of 32 interviews were conducted. 16 Participants were between 12 to 52 years of age. Parents of participants who were less than 18 years of age were present during the interview. For the rest 16 patients below 10 years of age, interviews were conducted with their parents. The discussion of each interview was transcribed. The interviews ranged in length from 12 to 30 minutes. From content analysis, four main themes were identified. They are; 1) the denial phase of parents, 2) over protective families, 3) social stigma, and 4) awareness of rehabilitation services, training centers, and government policies in communities. While the majority (95%) were aware of railway discounts many participants had not been aware of other welfare schemes run by the state government. Only 15% had heard of rehabilitation services in the state and vocational training facilities.This study highlights three major challenges in the rehabilitation of visually disabled people in western Uttar Pradesh: 1) The availability of rehabilitation services in the study area, 2) The awareness of visually disabled people about these services, and, 3) The robust strategy for creating awareness about these services at the community level.

Leber Optic Neuropathy and Low Vision Rehabilitation: A Case Report

Leber’s Hereditary Optic Neuropathy (LHON) is a maternally inherited mitochondrial disease, characterized by point mutations in mitochondrial DNA and subsequent mitochondrial dysfunction; which leads to a bilateral and painless loss of central vision. Unfortunately at this time, there is no proven treatment to prevent or reverse this optic neuropathy. Therefore, individualized low vision rehabilitation services and assistive devices are essential to help people with LHON regain their independence and quality of life. We highlight through a case study the importance of psychic support as well as the impact of low vision rehabilitation on a young man with LHON.

Prevalence of dry eye disease in the low vision population at the University of Colorado

PurposeTo evaluate the prevalence of diagnosed dry eye syndrome, meibomian gland dysfunction, and blepharitis amongst the low vision population. MethodsA retrospective analysis was conducted on patients seen in the University of Colorado Low Vision Rehabilitation Service between the dates of 12/1/2017 and 12/1/2022. 74 ICD-10 codes were used to identify patients as having dry eye syndrome or not having dry eye syndrome. Data was further analyzed to determine the prevalence of blepharitis and meibomian gland dysfunction using 29 blepharitis and 9 meibomian gland dysfunction ICD-10 codes. Data were also analyzed to determine the age and sex of the patients with diagnosed dry eye syndrome. ResultsThe percentage of patients with a diagnosis of dry eye syndrome by an eyecare provider was 38.02 %. The prevalence of dry eye syndrome by age group was 3.57 % for 0–19 years, 14.35 % for 20–39 years, 29.07 % for 40–59 years, 43.79 % for 60–79 years, and 46.21 % for 80 and above. The prevalence of meibomian gland dysfunction and blepharitis was 11.90 % and 9.1 % respectively. Dry eye syndrome prevalence amongst males was 31.59 % and 42.47 % for females. ConclusionThis study demonstrates that dry eye syndrome in the low vision population is a significant co-morbidity occurring in over a third of patients in the University of Colorado Low Vision Rehabilitation Service. These findings are meaningful as ocular comfort should not be overlooked while managing complex visual needs.

The Effect of Visual Impairment and Its Severity on Vision-Related and Health-Related Quality of Life in Jordan: A Comparative Cross-Sectional Study.

To assess the effect of visual impairment (VI), its severity, and ocular diseases on vision-related and health-related quality of life (QoL) in Jordan. A comparative, cross-sectional, hospital-based study was conducted among a group of 278 patients with VI aged ≥ 18 years, and age and sex-matched control group of 278 individuals with no VI. An interviewer administered the National Eye Institute Visual Function Questionnaire (NEI VFQ-25) and the Medical Outcomes Study 12-Item Short Form Health Survey (SF-12) to all participants. All the mean VFQ-25 subscales scores, physical component scale (PCS) and the mental component scale (MCS) of the SF-12 were significantly lower in patients with VI compared to controls with no VI. The VFQ-25 subscales (except general health and ocular pain), PCS, and MCS scores significantly decreased with more severity of VI. In the adjusted multivariate analysis, lower level of education (p=0.013), male sex (p=0.016), and the presence of cerebrovascular disease (p=0.019) were significantly associated with lower VFQ-25 composite scores in visually impaired patients compared to controls. Ocular disease duration of >5 years and progressive VI were significantly associated with lower VFQ-25 composite scores (p= 0.026 and p<0.001) respectively, in patients with VI. Glaucoma had a significantly larger reduction in mean scores of all the VFQ-25 subscales, and the PCS of the SF-12 compared to all other ocular diseases. Both VI and increasing severity of impairment were associated with reduced vision-related and health-related quality of life in adult Jordanians. Glaucoma patients and less educated people were particularly affected. Routine assessment of QoL in visually impaired patients and improving referral protocols to vision rehabilitation services is recommended to improve the QoL in those patients.

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

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. 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. 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. 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.

Improving access to vision rehabilitation care: implementation of the South East Ontario Vision Rehabilitation Service

ObjectiveTo investigate the effect of the South East Ontario Vision Rehabilitation Service (SOVRS), a centrally administered, regionally delivered vision rehabilitation service, on access to vision rehabilitation care. DesignPre-implementation (n = 1196) and post-implementation (n = 414) observational study. ParticipantsPatients referred for low-vision assessment at the hospital-based Kingston Health Sciences Centre Vision Rehabilitation Clinic and community-based Southeastern Vision Loss Rehabilitation Ontario clinics from 2014 to 2019. MethodsMarkers for access to care (e.g., patient rurality, diversity of referral source, distance and time travelled, and wait times) were compared before and after SOVRS implementation. ResultsAfter SOVRS implementation, there was a significant increase (p < 0.001) in the number of rural patients seen in the community. After SOVRS implementation, the hospital-based Vision Rehabilitation Clinic site experienced a significant increase in referrals from outside of Kingston (p < 0.001) and non-eye-care clinicians (p < 0.001), a significant reduction in patient time and distance travelled (p < 0.001), a 6% decrease in median wait time for low-vision assessments, and a significant reduction in wait time between referral and first available appointment (p = 0.011). ConclusionSOVRS, a novel service-delivery model for vision rehabilitation care, improved the delivery of and access to vision rehabilitation care in southeast Ontario through the integration of regional resources and services.

Referral to Vision Rehabilitation Services for Uveitis Patients: Referral Criteria and Barriers

ABSTRACT Purpose Despite the benefits of vision rehabilitation services (VRS) for uveitis patients, limited literature has examined issues in VRS access within uveitis. We surveyed American Uveitis Society members regarding VRS referral practices, criteria, and barriers. Methods Survey responses were collected from November 2022 to January 2023. Analysis summarized responses and compared response patterns of frequently-referring and infrequently-referring providers through Fisher’s exact tests and logistic regression. Results Most of the 33 respondents completed 1 to 5 monthly referrals using criteria of visual acuity loss, visual field loss, and difficulty performing vision-related activities. Key referral barriers included cost of services and insufficient patient-provider communication regarding vision loss. The practice of speaking to patients about vision loss during clinic visits was correlated with higher VRS referral rates (P = 0.047). Conclusions Greater patient-provider communication about vision loss may represent an opportunity to increase access to VRS.

Retrospective Analysis of Vision Rehabilitation for Veterans With Traumatic Brain Injury-Related Vision Dysfunction.

Traumatic brain injury (TBI) can trigger vision-based sequelae such as oculomotor and accommodative abnormalities, visual-vestibular integrative dysfunction, visual field loss, and photosensitivity. The need for diagnosis and management of TBI-related vision impairment has increased because of the increasing frequencies of combat warfighters returning from Iraq and Afghanistan with TBIs. The purpose of this research was to learn the sequelae of rehabilitation service delivery to veterans with TBI-related visual dysfunction after they are diagnosed. To accomplish this, we investigated vision rehabilitation assessments and interventions provided to veterans with TBI-related visual dysfunction at the Department of Veterans Affairs (VA) specialty polytrauma facilities for the 2 years following their injury. The research questions asked what assessments, interventions, and prescribed assistive devices were provided by VA specialty clinics (e.g., occupational therapy, polytrauma, and blind rehabilitation) and how service delivery was affected by demographic and clinical variables. A retrospective design was used to analyze VA data using natural language processing of unstructured clinician notes and logistic regression of structured data. Participants included 350 veterans with TBI who received rehabilitation at one of the five VA Polytrauma Rehabilitation Centers (Tampa, FL; Richmond, VA; Minneapolis, MN; San Antonio, TX; and Palo Alto, CA) between 2008 and 2017 and who were administered the 2008 congressionally mandated "Traumatic Brain Injury Specific Ocular Health and Visual Functioning Exam." The outcome variables were vision assessments, interventions, and prescribed assistive technology discovered via natural language processing of clinician notes as well as the vision rehabilitation specialty clinics providing the clinical care (polytrauma, occupational therapy, outpatient blind rehabilitation, inpatient blind rehabilitation, optometry, and low vision) extracted from VA structured administrative data. Veterans receiving rehabilitation for TBI-related vision dysfunction were most frequently assessed for saccades, accommodation, visual field, and convergence. Intervention was provided most frequently for eye-hand coordination, saccades, accommodation, vergence, and binocular dysfunction. Technology provided included eyeglasses, wheelchair/scooter, walker/cane, aids for the blind, and computer. There was an overlap in the services provided by specialty clinics. Services available and delivered were significantly associated with the comorbidities of each patient and the specialty clinics available at each VA Polytrauma Rehabilitation Center. The delivery of patient services should be driven by the needs of veterans and not by system-level factors such as the availability of specific vision rehabilitation services at specific locations. Traditional low vision and blind rehabilitation programs were not designed to treat the comorbidities and symptoms associated with TBI. To address this challenge, blind rehabilitation and neurologic recovery cross training is needed. Our findings document how five VA Polytrauma Rehabilitation Centers implemented this training in 2008. The next step is to extend and standardize this new paradigm to community care, where these post-deployment patients now reside.

Reported Perceived Barriers to Low Vision Rehabilitation Services among Ophthalmic Personnel in Ethiopia

Reported Perceived Barriers to Low Vision Rehabilitation Services among Ophthalmic Personnel in Ethiopia

Provision of low-vision rehabilitation services in Saudi Arabia

The prevalence of low vision is expected to increase at the national and international levels, given the aging population and the association between the prevalence of ocular disease(s) and increasing age. Thus, it is important to establish knowledge of the distribution, adequacy, and quality of available low vision rehabilitation services nationally and internationally. This will in turn help prioritize eyecare plans and initiatives, and thus deliver effective services. This cross-sectional study enumerated and surveyed all local government and information regarding the geographic location of each participating entity, entity affiliation, availability and types of low vision rehabilitation services, types of providers, and referral patterns were determined. The results of the current study showed that only 4% of the entities provided low vision rehabilitation services and most (75%) were located in the central region. Additionally, the majority of the services (95%) were basic optometric rehabilitation services whereas other services were either rarely offered or not offered at all. Overall, the current low vision rehabilitation services in Saudi Arabia are inadequate to meet the increasing prevalence of the low vision population. Thus, careful planning of eyecare services is required to meet this demand.

Low Vision Rehabilitation Service Utilization Before and After Implementation of a Clinical Decision Support System in Ophthalmology

Electronic clinical decision support systems apply clinical guidelines in real time and offer a new approach to improve referral and utilization of low vision rehabilitation (LVR) care. To characterize patients and factors associated with LVR service utilization with and without the use of an electronic health record (EHR) clinical decision support system (CDSS) alert. Quality improvement study using EHR data to compare patients who did and did not utilize LVR service after referral between November 6, 2017, and October 5, 2019, (primary) and to assess overall service utilization rate from September 1, 2016, to April 2, 2021, regardless of referral status (secondary). Participants in the primary analysis were patients at a large ophthalmology department in an academic medical center in the US who received an LVR referral recommendation from their ophthalmologist according to the CDSS alert. The secondary analysis included patients with best documented visual acuity (BDVA) worse than 20/40 before, during, and after the CDSS implementation. Data were analyzed from August 2021 to April 2022. Number and locations of referral recommendations for LVR service according to the CDSS alert in the primary analysis; active CDSS implementation in the secondary analysis. LVR service utilization rate was defined as the number of patients who accessed service among those who were referred (primary) and among those with BDVA worse than 20/40 (secondary). EHR data on patient demographics (age, sex, race, ethnicity) and ophthalmology encounter characteristics (numbers of referral recommendations, encounter location, and BDVA) were extracted. Of the 429 patients (median [IQR] age, 71 [53 to 83] years; 233 female [54%]) who received a CDSS-based referral recommendation, 184 (42.9%) utilized LVR service. Compared with nonusers of LVR, users were more likely to have received at least 2 referral recommendations (12.5% vs 6.1%; χ21 = 5.29; P = .02) and at an ophthalmology location with onsite LVR service (87.5% vs 78.0%; χ21 = 6.50; P = .01). Onsite LVR service (odds ratio, 2.06; 95% CI, 1.18-3.61) persisted as the only statistically significant factor after adjusting for patient demographics and other referral characteristics. Among patients whose BDVA was worse than 20/40 before, during, and after the CDSS implementation regardless of referral status, the LVR service utilization rate was 6.1%, 13.8%, and 7.5%, respectively. In this quality improvement study, ophthalmologist referral recommendations and onsite LVR services at the location where patients receive other ophthalmic care were significantly associated with service utilization. Ophthalmology CDSSs are promising tools to apply clinical guidelines in real time to improve connection to care.

Vision rehabilitation in glaucoma patients.

Vision rehabilitation services are important but underutilized resources for patients with glaucoma. Glaucoma and its impact on vision can affect patients' abilities to read and drive, two activities of daily living that are associated with quality of life and functional independence. In this review, we provide an overview of low vision, discuss barriers to vision rehabilitation, and outline various strategies and interventions to optimize visual function and quality of life in patients with glaucoma. Studies have shown that glaucoma negatively impacts reading, driving and overall quality of life. Decreased visual acuity, visual field loss and reduced contrast sensitivity play a role. Low vision services and interventions can help patients maximize visual function and improve their quality of life. Barriers to receiving these services exist at multiple levels and an increased awareness and integration into routine ophthalmic care are needed to deliver comprehensive care. Glaucoma is one of the leading causes of low vision. Ophthalmologists who treat glaucoma often tend to focus on objective measures to monitor progression and disease severity, but the functional impact of glaucoma should also be addressed. Low vision services can benefit patients, particularly for reading and driving, and should be considered as an essential component of patient care.

Parent-Reported Visual Concerns in Children with Cerebral Visual Impairment Presenting to a Pediatric Neurology Clinic.

Children with cerebral visual impairment (CVI) present with delayed developmental milestones. Pediatricians and pediatric neurologists are usually the first point of contact, and eye exam largely remains referral based. This study documented the visual concerns reported by parents of children with CVI visiting a pediatric neurology clinic. Additionally, we investigated the association between visual concerns, functional vision measures and visual functions. A cross-sectional study was undertaken in children with CVI (chronological age range: 7 months-7 years). Visual concerns reported by the parents/caregivers were documented as open-ended statements. Additionally, a functional vision assessment was conducted using the CVI Range instrument with phase 1, 2 and 3 indicating low, moderate and high visual functioning, respectively. Grating acuity and contrast sensitivity were measured using Teller acuity cards-II and Ohio contrast cards respectively. A total of 73 children (mean age of 2.84 ± 1.87 years) were recruited. Sixty-eight parents reported visual concerns that were broadly grouped into 14 unique concerns. Nineteen parents (27.9%) reported more than one visual concern. Difficulty maintaining eye contact and recognizing faces were the top two visual concerns in phases 1 and 2. Missing objects in the lower visual field was the top concern in phase 3. A larger number of visual concerns were reported in phase 1 (43%) than phase 2 (40.6%) and phase 3 (16.2%). Multiple regression analysis revealed that grating acuity, contrast sensitivity and chronological age were able to predict the functional vision, F (3, 55) = 63.0, p < 0.001, r2 = 0.77. Targeted questions enquiring about eye contact and face recognition can be included in history elicitation in children with CVI in pediatric neurology clinics. In the presence of visual concerns, it will be important to assess grating acuity and contrast sensitivity. A poor functional vision score requires referral for eye examination and vision rehabilitation services.

Improving assistive technology access to students with low vision and blindness in Delhi: A school-based model.

Assistive technology (AT) has recently received considerable attention around the world. Studies have shown poor access to assistive technology for visual impairment (ATVI) in schools for the blind in India. The present article aimed at designing a school-based model to improve AT access in schools and provide hands-on training, and identify types of ocular morbidities present among students. The vision rehabilitation (VR) team of a tertiary eye-care center visited schools for the blind as a part of community-based VR services. The team conducted a basic eye examination and assessed best-corrected vision acuity (BCVA) and provided VR services. Furthermore, two schools were selected to establish an ATVI learning center as a pilot model. In total, 1887 students were registered for VR and obtained their disability certificates in 2019-20. Retina problems (25.7%), globe abnormalities (25.5%), optic nerve atrophy (13.6%), and squint (12.0%) were common ocular problems identified in students. Around 50.3% of students had BCVA3 1/60 in the better eye who would be benefited from visual-based AT, and the remaining students with visual substitution AT. Further, 20.8% of them who had near vision between N18 to N24 would be benefitted from large print books. Two schools were provided ATVI with support from the WHO. Familiarization, demonstration, and initial training for ATVI were carried out. A sizable number of the students would be benefitted from visual-based AT apart from visual substitutions AT. Students were interested to have such ATVI centers in the school for academic and non-academic skills development.

The Basic VRS-Effect Study: Clinical Trial Outcomes and Cost-Effectiveness of Low Vision Rehabilitation in Portugal.

The aim of this study was twofold: (1) to investigate the clinical impact of vision rehabilitation in patients with vision impairment and (2) to investigate the cost-effectiveness of a basic vision rehabilitation service in Portugal. The trial recruited patients diagnosed with age-related macular degeneration or diabetic retinopathy (DR) and visual acuity in the range 0.4-1.0logMAR in the better-seeing eye. Participants were randomised to one of the study arms consisting of immediate intervention and delayed intervention. The intervention included: new refractive correction, optical reading aids, in-office training and advice about modifications at home. Visual ability, health-related quality of life and costs were measured. Economic analysis was performed to evaluate whether the intervention was cost-effective. The trial compared the outcomes 12 weeks after the start in both arms. Of the 46 participants, 34 (74%) were diagnosed with DR, 25 (54%) were female, and mean age was 70.08 years (SD = 8.74). In the immediate intervention arm visual ability increased a mean of 0.523 logits (SE = 0.11) (p < 0.001). Changes in the delayed intervention arm were not statistically significant (p = 0.95). Acuity in the better-seeing eye, near acuity and critical print size also improved during the study. The mean cost of the intervention was €118.79 (SD = 24.37). The incremental cost-effectiveness ratio using the EQ-5D-5L was 30,421€/QALY and 1186€/QALY when using near acuity. The current study gives evidence of positive clinical impact of a basic vision rehabilitation intervention and shows that a basic vision rehabilitation service is cost-effective. These findings are important to clinical and rehabilitation practices and for planning vision rehabilitation services. Retrospectively registered, 21/01/2019.

Increased quantity and diversity of patient referrals following the introduction of a novel vision rehabilitation model

Despite effective vision rehabilitation (VR) interventions, no gold standard model of care delivery has been established. The institution of the South East Ontario Vision Rehabilitation Service (SOVRS) introduced a centralized intake, an occupational therapist as a systems navigator, and improved communication pathways between low vision services in order to optimize regional VR care. The aim of this study is to compare the SOVRS model of VR to a traditional, hospital-based pre-SOVRS-implementation model using referral data. A single-site (Vision Rehabilitation Clinic at Kingston Health Sciences Center), retrospective medical chart review was performed. Data were gathered from the electronic medical records of patients who received a low vision assessment at the pre-SOVRS-implementation clinic (2017) and the SOVRS clinics (2019). A total of 245 charts were reviewed over the two study periods. There were no significant differences in the age, gender, or diagnoses causing vision loss between 2017 and 2019. One hundred nine incoming referrals were received in 2017, with 136 in 2019, representing a 25% increase in incoming referrals ( p &lt; .001). The proportion of incoming referrals from non-ophthalmologists rose from 3.7% in 2017 to 31.9% in 2019 ( p &lt; .001). The number of outgoing referrals also increased significantly, from 113 outgoing referrals in 2017 to 259 in 2019 ( p &lt; .001), equivalent to a mean of 1.04 ± 0.68 (± standard deviation) outgoing referrals per incoming referral in 2017 and 1.90 ± 0.97 outgoing referrals per incoming referral in 2019. Outgoing service referrals also diversified significantly in 2019 ( p &lt; .001), with more referrals to services such as VR health service organizations and community services. The SOVRS model was able to increase both the quantity and diversity of incoming and outgoing referrals by adopting several key strategies during its development. By expanding referrals, SOVRS increased the services available to patients and enabled a larger population to receive VR care.

Providing Accessible Fall Prevention Education for Older Adults With Low Vision

This study modified the educational content of an evidence-based fall prevention intervention to make it visually accessible for older adults with low vision. We piloted the intervention on 9 older adults receiving low vision rehabilitation services. Following the intervention, participants demonstrated increased comprehension of the content, perceived a greater understanding of fall prevention strategies, and reported high satisfaction with the intervention's accessibility. Individuals with low vision may have difficulty reading and comprehending printed educational materials. Modifying print materials to improve readability may result in greater understanding of the educational content.

Intersectionality and access to visual rehabilitation services: Experiences of people with low vision, a qualitative study

Low vision is a condition of visual impairment, generated by an underlying pathology that affects visual functioning and the development of daily activities. In the field of visual impairment, the developments in the analysis of access to rehabilitation services are scarce and incipient. The study approaches the understanding of the experiences of people with low vision in Medellín, Colombia, in their search for visual rehabilitation services. Ethnographic collective case study was conducted. Intersectionality was adopted to explore people’s experiences with low vision management health services. Five women and four men with low vision who attended the healthcare center participated in the study. Twenty-nine interviews and 16 participant observation exercises were carried out. Three categories emerged in the study: (1) I had never heard of low vision services; (2) Interaction with the health system: A path of struggles; and (3) Barriers that are exacerbated by the intersection of multiple identities and systems of oppression. The Colombian health system acts as an axis of structural oppression that interacts with the economic condition, educational level, and geographical location to generate greater difficulties for the identification of low vision management options, which also interact with the multiple and dynamic identities of each subject.
