Blindness and eye disease in Kenya: ocular status survey results from the Kenya Rural Blindness Prevention Project.

Prevalence and Causes of Blindness and Low Vision in Southern Sudan

“…Cataract was considered the commonest cause of blindness in Mankien (41.2%). This is consistent with findings from other countries in Africa where cataract has been found to be the leading cause of blindness: Kenya (38%) [25], Nigeria (48%) [22], Malawi (40%) [23], and the Gambia (45%) [20]. However, trachoma was almost as common a cause of blindness as cataract (35.3%) and was the leading cause of all forms of visual impairment (46.8%).…”

“…However, trachoma was almost as common a cause of blindness as cataract (35.3%) and was the leading cause of all forms of visual impairment (46.8%). The proportion of blindness due to trachoma by far exceeds what has been observed in other countries where trachoma is endemic: Mali (12.1%) [29], Kenya(18.7%) [25], Ethiopia (20.6%) [27], and Tanzania (26%) [24]. In Mankien, trachomatous trichiasis (TT) has been documented in children as young as 4 y, overall (all ages) TT prevalence was 9.6%, and prevalence of bilateral trachomatous corneal opacity was 3.1% [30].…”

Ophthalmology in Luanda (Angola): a hospital based report.

“…Trauma was found to be the second most prevalent blinding condition in the Kenya Rural Blindness Prevention Project. 13 Vitamin A deficiency and measles are responsible for more than half the childhood blindness in Africa.3 In our series, xerophthalmia was ranked in fifth place for all age groups. Among children under 6, xerophthalmia and cataracts share first place.…”

Evaluation of E-optotypes as a screening test and the prevalence and causes of visual loss in a rural population in SW Uganda

“…10 The prevalence of bilateral blindness in this rural population is higher than in the U.S. (0.4% versus 0.2%) especially considering that American estimates are based on a more liberal visual acuity cut-off criterion for blindness (equal or worse than 6/60). 17 However, compared with other countries, bilateral blindness was less common than in rural Kenya (0.7%), 9 and much lower than in Nepal (0.9%), 18 Malawi (1.3%) 19 or Tanzania. 4 Similarly, the prevalence of bilateral visual impairment (1.6%) observed in the study was lower than that observed in Kenya (2.5%), 9 Ethiopia (2.5%) 6 and Tanzania 4 but close to that in Nepal (1.6%).…”
