Abstract
Around 1.5 million Canadians live with some form of vision impairment. The demand for vision rehabilitation (VR) services is projected to increase as the number of older adults with age-related vision loss rises. To inform programmes and policies for VR, we aimed to answer two research questions: (1) How are VR services delivered in Canada? and (2) If gaps exist in current delivery of VR services, how can they be characterized? We used Arksey and O’Malley scoping review framework. A comprehensive search of five databases (PubMed, CINAHL/EBSCO, EMBASE, ProQuest, and Global Health) was performed during January 2019 and then updated in March 2021. Index terms and keywords relating to vision loss or impairment and rehabilitation were used. Non-peer-reviewed (grey) literature, in the form of reports and policies on VR in Canada, was sourced via Google/Google Scholar. To be included, sources had to (1) focus on VR services in Canada, (2) be available in English or French, and (3) be published after 2003. Data were extracted and analysed thematically to describe VR services across provinces and to identify gaps in service delivery in Canada. Out of 1311 studies identified, 62 were included. Findings indicate that the structure of VR services as well as provincial funding for assistive devices varies across provinces. The reported gaps at the level of service providers, users, and delivery systems were lack of awareness about the benefits of VR, limited collaboration and coordinated services between eye care and VR services, delayed referral to VR, shortage of specialists, and insufficient funding and training for vision devices. This article describes VR services in Canada and documents important gaps in VR services and research evidence across provincial jurisdictions. Future work to address gaps, and develop and evaluate interventions to facilitate optimal VR services is imperative.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
