Mayombian 种族，蔬菜低吸入，胰岛素处理，糖尿病的 nephropathy 和严重糖尿病的 retinopathy 是在糖尿病的非洲人的盲目的决定因素

AIM:to determine the frequency and causes of blindness in diabetic Africans.METHODS:The study was a cross-sectional survey carried out among known black diabetics consecutively admitted at the Teaching Hospital,University of Kinshasa,between 2005 and 2007.Examination methods included interviewer-administered structured question naire,eye examinations(visual acuity,tonometry,funduscopy),and fasting plasma glycaemia test.RESULTS:Of the 227 patients examined,15.9% had blindness.Univariate analyses showed significant association between female,severity of diabetic retinopathy,Mayombian ethnic group,use of insulin treatment,low intake of vegetables,diabetic nephropathy,open angle glaucoma and blindness in all diabetics.After logistic regression,only diabetic nephropathy,use of insulin treatment,macular oedema,Mayombian ethnic group and vegetables low intake were the independent risk factors of blindness in all diabetics.However,after logistic regression in the sub-group with diabetic retinopathy,only open angle glaucoma and proliferative diabetic retinopathy were the independent determinants of blindness.CONCLUSION:The majority of the causes of blindness in these diabetic Africans are avoidable.It is recommended that appropriate diabetes care,nutrition education,periodic eye examination and laser photocoagulation facilities should be provided for treating diabetics in sub-Saharan Africa.
