title: Onchocerciasis and optic atrophy in the Savannah area of Ghana.
abstract: The ocular findings in the male population of 3 villages from a hyperendemic area of onchocerciasis in North Ghana have been recorded. Vector control in the Volta River Basin has led to reduced microfilarial loads and improved tolerance of treatment with diethylcarbamazine-citrate (DEC-C). Prevalence of posterior eye lesions increased sharply above the age of 30 years in the survey population. In patients with palpable onchocercomas (nodules) serious pathology of the posterior segment of the eye was found twice as frequently as in onchocerciasis patients without nodules. In the village visited by the Mobile Eye Team since 1978 the prevalence of serious eye lesions was slightly lower than in the two villages never visited by the eye team. Desirability to give treatment to the younger population with low incidence of serious eye lesions is expressed. Attention is drawn to the increased danger of adverse reactions to treatment in the presence of posterior eye lesions.
