Few epidemiological data describe the prevalence of blindness and visual impairment in Senegal. Data from West African studies estimate blindness prevalence between 1.2 - 3.4% and that of visual impairment between 10.4 - 17.1%. IRIS Mundial (IM) is a non-governmental organization collaborating with l'Association St-Louisienne pour la Vue (ASV) to develop eye care in Senegal.
Describe the relative importance of and causes of blindness and visual impairment in a population consulting for vision problems in the Senegalese region of St. Louis, to assist in planning of relevant eye care programs.
Results from eye exams carried out by a team from IM in 2018 have been complied and analyzed.
In all, 1944 patients were examined (56.5% female). Some 25.7% of patients presented a visual impairment (22.5% moderate; 3.2% severe). Regarding refractive error, 15.3% of patients had myopia, 10.7% had hyperopia, 54.8% had astigmatism and 55.8% were presbyopic. Clinically significant cataracts is present in 17.4% of patients and glaucoma in 2.5%.
Our data give a glimpse of the prevalence of visual impairment and ocular disease in St. Louis, Senegal. Uncorrected refractive error, cataracts and glaucoma are present in this population and may guide the planning of relevant eye care interventions.
关于塞内加尔失明和视力损害患病率的流行病学数据很少。西非研究的数据估计失明患病率在1.2%-3.4%之间，视力损害患病率在10.4%-17.1%之间。国际虹膜组织（IM）是一个非政府组织，与圣路易视力协会（ASV）合作在塞内加尔开展眼保健工作。
描述在塞内加尔圣路易地区因视力问题就诊的人群中失明和视力损害的相对重要性及病因，以协助规划相关眼保健项目。
对IM团队在2018年进行的眼部检查结果进行了汇总和分析。
共检查了1944名患者（56.5%为女性）。约25.7%的患者存在视力损害（22.5%为中度；3.2%为重度）。关于屈光不正，15.3%的患者有近视，10.7%的患者有远视，54.8%的患者有散光，55.8%的患者有老花眼。17.4%的患者存在具有临床意义的白内障，2.5%的患者患有青光眼。
我们的数据让我们初步了解了塞内加尔圣路易地区视力损害和眼病的患病率。该人群中存在未矫正的屈光不正、白内障和青光眼，这可能为相关眼保健干预措施的规划提供指导。
