Uncorrected refractive errors in sub-Saharan Africa
Sherwin et al extracted data from population-based prevalence surveys (11) performed in 10 countries, encompassing 39 458 adults. The prevalence of blindness (presenting visual acuity (PVA) <3/60 in better eye) ranged from 1.1% in an urban district of Cameroon to 7.9% in a rural district in Ethiopia. The proportion of moderate visual impairment (PVA ≤6/60 and >6/18) ranged from 12.3% to 57.1%. The highest proportion of visual impairment due to uncorrected aphakia was found in Gambia (15.2%) and Nigeria (15.8%), respectively. Uncorrected refractive error is not a major cause of blindness in sub-Saharan Africa (see page 927).
RNFL thickness in preterm and at term born children
Åkerblom et al measured the retinal nerve fibre layer (RNFL) thickness in 62 children born at gestational age of ≤32 weeks and a control group of 54 children born at term with normal birth weight (BW). RNFL thickness was measured with Stratus OCT 3 at mean age of 8.6 years in the preterm children …
