    Notes: Abstract Onchocerciasis is a devastating blinding disease caused by the parasite Onchocerca volvulus that infects about 80 million people, causing blindness and visual impairment in 1–2 million people. In hyperendemic areas, more than half of the population will become blind from onchocerciasis before they die. Blindness is the most important effect of the disease and results, in part, from direct invasion of the eye by microfilariae. The recent development of ivermectin has revolutionized our ability to treat this disease. An annual oral dose of only 150 mg/kg completely suppresses the disease manifestations. Programs for the community-based mass distribution of ivermectin are now being conducted and promise to control this major blinding scourge.

    Prevalence and causes of vision loss in central Tanzania (1991)

    Notes: Abstract A population-based survey of the prevalence of major blinding disorders was conducted in three villages in central Tanzania. Overall, 1827 people overthe age of seven years old were examined. In those age seven and older, the prevalence of bilateral blindness (visual acuity in the better eye of 〈3/60) was 1.26% and monocular blindness (visual acuity of 〈3/60 in one eye) was 4.32% and the prevalence of visual impairment (visual acuity 〈6/18 but ≥3/60 in both eyes was 1.04% and in one eye was 1.75%. Corneal opacities were responsible for 44% of bilateral and 39% of monocular blindness and resulted from trachoma, measles often in association with Vitamin A deficiency, keratoconjunctivitis, and the use of traditional eye medicines. Cataracts accounted for 22% of bilateral and 6% of monocular blindness. Readily preventable or reversible causes of blindness were responsible for 65% of cases of bilateral and 46% of monocular blindness.

    Etiology of corneal opacification in central Tanzania (1993)

    Notes: Abstract The frequency and causes of visually significant corneal opacification in central Tanzania was assessed by a population-based survey. The overall prevalence of bilateral corneal opacification was 1.16% (95% CI 0.31–1.44) and unilateral corneal opacification was 2.07% (95% CI 1.55–2.73). Bilateral corneal opacification was most frequently associated with trachoma, keratoconjunctivitis, vitamin A deficiency and measles. Unilateral corneal opacification had similar causes with the addition of cases caused by trauma. Corneal scarring is a frequent occurence in this region. The majority of cases of corneal opacification are secondary to potentially preventable or treatable causes.
