RESUMO
A study of 326 volunteers from a rural farm settlement in Aniocha North, Delta State, Nigeria, was conducted between December 1999 and September 2000. Volunteers were screened for eye lesions and onchocerciasis. Microfilariae were found in the skin tissues of 134 (41.1%) inhabitants; of these, males had greater microfiladermia (49.9%) than females (33.3%). The percentage prevalence of the clinical signs of onchocerciasis in the farm settlement were: hanging groin 14.1%, onchocercal nodules 25.1%, onchocercal dermatitis 27.6%, scrotal enlargement 3.7%. The percentage prevalence of the eye lesions among those with onchocerciasis were: cataract 24 (7.4%), glaucoma 12 (3.7%), optic atrophy 2 (0.6%) and uveitis 18 (5.5%). Impaired vision was found in 80 (24.5%) inhabitants and blindness was suffered by 2(0.6%) inhabitants.

Une etude a ete entreprise dans la Vallee du Mbam afin de mieux repartir l'onchocercose dans cette region. Dans chacun de ces villages; environ 150 sujets ages de cinq ans et plus ont ete examines du point de vue clinique et parasitologique. Il ressort de cette etude que tous ces villages etudies sont hyperendemiques. Cependant; les charges microfilariennes moyennes varient largement. Ainsi; cette enquete confirme qu'au Cameroun; en zone de transition savane-foret; l'onchocercose a des repercussions oculaires graves. Un traitement de masse par ivermectine serait certainement souhaitable dans la region de Bafia
