Being visually impaired or legally blind (having vision that is uncorrectable or cannot be corrected to a legally acceptable level) is inherently uncertain. Although uncertainty can result in positive, negative, or neutral consequences, little is known about how uncertainty is experienced and negotiated in this understudied population. Thus, through in-depth, semi-structured interviews of 24 individuals with a visual impairment, we apply uncertainty management theory (UMT) to examine the communication strategies visually impaired individuals used to manage the personal, vision-related, and social uncertainty they experienced. Many participants appraised the uncertainty negatively and consequently aimed to reduce it by seeking social support and information, using instrumental strategies, and proactively disclosing their visual impairment. Interviewees who preferred to remain uncertain maintained it by avoiding thinking about their visual impairment or worsening vision and/or by concealing their low vision and passing as sighted. Last, some participants, particularly those who were born with low vision or had been visually impaired longer, learned to adapt to the uncertainty through reframing and accepting, self-care, and by turning to God. The study also uncovered that some participants' uncertainty management was limited by ableist constraints, such as inadequate support systems, systemic barriers, and stigma. The study also underscores the universal and fluid nature of uncertainty and uncovers tangible ways individuals with visual impairment can navigate uncertainty within a pervasive cultural biomedical model of disability.

Background: Gait impairment in Parkinson's disease (PD) occurs early and pharmaceutical interventions do not fully restore this function. Visual cueing has been shown to improve gait and alleviate freezing of gait (FOG) in PD. Technological development of digital laser shoe visual cues now allows for visual cues to be used continuously when walking.

Phototaxis is a critical behavior in insects and is closely linked to vision and environmental adaptation. Understanding how insects perceive light and exhibit phototactic responses is crucial for assessing the ecological impact of artificial light at night. However, the molecular and neural mechanisms that regulate phototactic responses in insects remain largely unknown.

Background: This study aimed to explore the barriers and facilitators of implementing rehabilitation interventions for visual field loss due to stroke.
Methods: The study was a qualitative exploration using one-to-one interviews coded using template analysis and the COM-B a-priori framework. Participants were five occupational therapists from hospital (n=4) and community (n=1) National Health Service (NHS) stroke care settings in England.

Clinical Relevance: Good vision is critical for childhood development and education. Pre-school vision screening is important for early detection and treatment of visual problems, and prevention of life-long vision loss.
Background: The aim of this study was to determine the prevalence of vision impairment (VI) and refractive error (RE) in rural Nepalese children under five years of age.

Cognitive functions emerge from dynamic functional interplay of cortical and subcortical areas that form networks. Preterm birth poses a risk for the formation and functionality of brain networks which may lead to severe brain dysfunctions. Infants born extremely preterm have the highest risk of developing neurocognitive impairments.
