Vision Loss and Comorbid Conditions
A CDC study (Crews, Jones, & Kim, 2006) revealed that older people who report vision loss are more likely to experience comorbid conditions than people without vision loss. Moreover, these combinations of conditions among older people have serious consequences for overall health, ability to perform tasks, and to participate in social roles. This study estimated a total population of people older than age of 65 experience vision loss to be 5.7 million people.
The number of older people experiencing vision loss and other comorbid conditions is substantial: 1.2 million experience both vision loss and diabetes; 3 million have compromised hearing and vision; 3 million report vision loss and mild/moderate risk of depression; 350,000 report severe risk of depression; and nearly 900,000 report stroke and vision loss. The population estimates are for older people residing in the community and not institutional settings. The combination of vision impairment and other health conditions substantially compromises the performance of activities and social participation (Crews, Jones, & Kim, 2006).

In addition to chronic conditions being more common among older people with vision loss, a variety of studies indicate that older people with vision loss have greater risk of falls and fear of falling (Freeman, Muñoz, Rubin, & West, 2007), cognitive decline (Lin, Gutierrez, Stone, Yaffe, Ensrud, Fink, Sarkisian, Coleman, & Mangione, 2004), and greater risk of premature death (Freeman, Egleston, West, Bandeen—Roche, & Rubin) than people without vision loss.
