Between December 1999 and September 2000, an investigation on 326 inhabitants who voluntarily participated in screening for eye lesions and onchocerciasis in a rural farm settlement in Aniocha North local government area of Delta State, Nigeria was carried out.

The percentage prevalence of the clinical signs of onchocerciasis in the farm settlement was hanging groin 14.1%, onchocercal nodules 25.1%, onchocercal dermatitis 27.6% and scrotal enlargement 3.7%. The percentage prevalence of the eye lesions among the onchocerciasis infected inhabitants was cataract 7.4%, glaucoma 3.7%, optic atrophy 0.6% and uveitis 18 (5.5%).
