In North Cameroon, the vector of Onchocerca volvulus (causative agent of human onchocerciasis) also transmits 2 filariae of animals: O. ochengi from cattle and O. ramachandrini from wart hogs. In order to assess the qualitative and quantitative roles of these 'animal filariae' in the epidemiology of O. volvulus, the transmission of the 3 parasites was(More)
In 26 villages (1987 population 12,302), hyperendemic for savanna onchocerciasis in North Cameroon, ivermectin was distributed annually between 1987/89 and 1995. Each year until 1992, ophthalmologic examinations were performed before treatment. A final examination was made in 1995. The effects of ivermectin on ocular onchocerciasis were assessed by(More)
Prior to the initiation of an onchocerciasis control program based on the mass administration of ivermectin in the rain forest of southwestern Cameroon, a preliminary baseline study of the area was conducted. The results of this study showed that onchocerciasis was hyperendemic in the area. Skin symptoms and signs were observed including pruritus (67.4% of(More)
OBJECTIVES To determine the prevalence and the various types of glaucoma in a Black urban Cameroonian population. MATERIAL AND METHOD A retrospective analysis of 1,343 glaucomatous patients' files (757 men and 586 women) from a total of 24,462 Cameroonian patients of all ages was carried out from January 1991 to December 2001 in the Douala General(More)
In the onchocerciasis-endemic rain forest area of the Rumpi Hills in southwestern Cameroon, a community-based trial of ivermectin, given either once or twice a year over a three-year period (1988-1991), confirmed that the drug is a potent microfilaricide. The side effects recorded following the first treatment were edema, fever, pruritus, generalized body(More)
AIM To study the particularities of late post-traumatic glaucoma with irido-corneal angle injuries in black Cameroonians. MATERIAL AND METHODS Retrospective analysis of 1343 files of glaucomatous patients was carried out from January 1991 to December 2001 at the Douala General Hospital in Cameroon in Central Africa. Fifty seven of them had post-traumatic(More)
Glaucoma is one of the major causes of blindness throughout the world; mostly because patients come to consultation late. We performed a prospective study of the intraocular pressure, fundus and perimetry in 307 young Cameroonians (20 to 39 years old). Glaucoma was found in 5.8% of cases. This study shows that the disease appears early in black people and(More)
Authors report the results of a retrospective study of epidemiological, clinical and therapeutical aspects of pterygium carried at the ophthalmological service of the Douala General Hospital. During the period of the study, 167 patients with pterygium were registered, which means a prevalence of 1.10%. The mean age of the patients was 41.76 years with(More)
The authors carried out a retrospective study in order to assess the efficacy of intrabled autologous blood injections after trabeculectomy. The indication for treatment was hypotony associated with overfiltration. Twelve eyes of 12 patients including seven men (58.3%) and five women (41.67 %) underwent from one to four (mean 1.7) subconjunctival(More)
