Visual Impairment in Diabetes
Visual acuity was measured in a population-based study of diabetic retinopathy in southern Wisconsin. Persons diagnosed prior to 30 years of age and taking insulin (younger onset, n = 996) and those diagnosed at 30 years of age or older (older onset, n = 1370) were examined. 
Causes and prevalence of visual impairment among adults in the United States.
OBJECTIVES: To estimate the cause-specific prevalence and distribution of blindness and low vision in the United States by age, race/ethnicity, and gender, and to estimate the change in these prevalence figures over the next 20 years. 
Age-Specific Causes of Bilateral Visual Impairment
Objectives To describe the age-specific prevalence of common eye diseases causing bilateral visual impairment and estimate the total number of Australians with cause-specific visual impairment. 
Prevalence of Visual Impairment among Deaf and Mute Schools Children

Visual Impairment Following Stroke – The Impact on Quality of Life: A Systematic Review
Background: The visual impairments caused by stroke have the potential to affect the ability of an individual to perform activities of daily living. An individual with visual impairment may also have reduced level of independence. The purpose of this review was to investigate the impact on quality of life from stroke related visual impairment, using subjective patient reported outcome measures.
