Eye Care and Prevention of Blindness Programme, Ministry of Health, Accra, Ghana.


The clinical features of onchocercal dermatitis include itching, papular and papulomacular rash, skin atrophy and depigmentation. The results of a multi-country study have shown that > 30% of the population in communities where onchocerciasis is endemic have onchocercal dermatitis. The most troubling symptom suffered by those affected was itching and this was closely related to reactive onchocercal dermatitis (acute papular, chronic papular and/or lichenified lesions). Reactive onchocercal dermatitis and troublesome itching were common in all age-groups and were an important cause of stigma in most endemic communities, those affected suffering from poor self-esteem. Concern about onchocercal depigmentation varied between study sites and subjects.
