Introduction: To evaluate the long-term effect of corneal transplantation on mental health outcomes and to assess potential predictors of these outcomes.
Methods: For this multicentre prospective cohort study, patients awaiting corneal transplantation were recruited from 11 (academic) hospitals and eye clinics in the Netherlands. Participants (n = 238) completed the Centre for Epidemiological Studies Depression scale (CES-D), the Hospital Anxiety and Depression Scale-Anxiety subscale (HADS-A) and the Dutch ICF Activity Inventory Emotional Health subscale (DAI-EH) and Fatigue subscale (DAI-F) 1 month prior and 3, 6, 12 and 24 months after corneal transplantation.
Significance: This research contributes to the concept of cognitive overload and the association between concentration and fatigue in individuals with visual impairment (VI). Gaining more insight into these and other factors explaining cognitive overload is essential for a better understanding, prevention, and treatment of fatigue severity in individuals with VI.
Purpose: Individuals with VI need to use additional cognitive resources to compensate for their loss of vision.
The multiple mediating effects of vision-specific factors and depression on the association between visual impairment severity and fatigue: a path analysis study.

Background: Severe fatigue is a common symptom for people with visual impairment, with a detrimental effect on emotional functioning, cognition, work capacity and activities of daily living. A previous study found that depression was one of the most important determinants of fatigue, but less is known about disease-specific factors in this patient population. This study aimed to explore the association between visual impairment severity and fatigue in adults with low vision, both directly and indirectly, with vision-specific factors and depression as potential mediators.

- The study aimed to compare physical activity (PA) levels between children with visual impairment (VI) and those with normal sight using wearable devices for one week.
- Results showed that children with VI engaged in lower overall activity levels, particularly vigorous PA, and were more sedentary during school hours, despite being less sedentary before school and on weekends.
- The findings suggest a need for schools to implement more intense physical activity programs specifically designed for children with visual impairment to improve their overall activity levels.
Purpose: Little is known about the utilization of low vision services (LVS) in Germany. To understand which persons and how often these services would be utilized, this study aimed to investigate low vision aids (LVAs) provision in an urban setting and to describe user characteristics and trends in their characteristics.
Methods: A retrospective study based on a population-based healthcare claims database in Cologne (N = ~ 500,000), Germany.
