“…The prevalence of blindness among the unemployed was 0.6%. Possibly, because the unemployed were elderly who had decreased expectations in life (10). The data suggest that the burden of VI in Kibera is ten times higher than that of blindness.…”

Objective: To determine the prevalence and causes of visual impairment and blindness among Kibera slum dwellers. Design: Population based Survey. Setting: Kibera Slums, Kibera Division, Nairobi, Kenya. Subjects: One thousand four hundred and thirty eight randomly selected slum dwellers. Results: The prevalence of blindness and visual impairment was 0.6% (95% CI: 0.21 to 1.0), and 6.2% (95% CI: 4.95 to 7.15) respectively. 37.5% of those found blind were due to cataract followed by refractive errors 25.0%. 58.1% of those with visual impairment had refractive errors while 35.5% had cataracts. Females had a higher prevalence of visual impairment compared to males but the difference was not statistically significant (P = 0.104). Conclusions: Prevalence of blindness in Kibera slums is slightly lower than the estimated national average (0.7%) while that of visual impairment is almost three times higher. The leading causes of blindness are cataract followed by refractive errors. For visual impairment, refractive error was the leading cause followed by cataract. Recommendation: Kibera slum dwellers are in need of comprehensive eye care services offering cataract surgery and low cost spectacles.

“…Where necessary, alternative arrangements should also be considered. The implications of not doing anything are social isolation with increased risk of depression [37][38][39][40]. Ensuring a safe walking environment would not only improve the independence of people with vision impairment but it is also an important element of quality of life and provides a method of low impact exercise, which in turn can maintain and improve the health of the walker [32].…”

“…1 A systematic review of clinical trials, performed in older people in a community setting, included the assessment of visual function and concluded that evidence for effectiveness of visual screening was lacking, but a small beneficial effect cannot be excluded. 8 In this respect the United States Preventive Services Task Force (USPSTF) recommends visual screening for impaired vision in people aged over 65 years using the Snellen chart (grade B recommendation). 7 The Canadian Task Force on Preventive Health Care (CTF) points out that the high prevalence of visual defects in elderly people and the existence of effective treatment are sufficient reasons for including periodical visual acuity testing with a Snellen sight chart.…”
