Prevalence of blindness and low vision of people over 30 years in the Wenchi district, Ghana, in relation to eye care programmes.
A population based survey on the prevalence of major blinding disorders was conducted in the Wenchi district in central Ghana between March and May 1991.
In 10 villages, 1425 people of 30 years and older were screened, using the WHO eye examination record.
The prevalence of bilateral blindness above 30 years proved to be 1.7% (best acuity <3/60): the prevalence of low vision above 30 years was 2.0% (best visual acuity 6/18 to 3/60).
The causes of blindness were determined as cataract (62.5%), onchocerciasis (12.5%), corneal opacity (non-trachomatous) (8.2%), refraction anomalies (4.2%), phthisis bulbi (4.2%), optic atrophy (4.2%), and vascular retinopathy (4.2%).
