无糖尿病视网膜病变的糖尿病性视神经病变患病率调查

Survey on prevalence rate of diabetic optic neuropathy in patients without diabetic retinopathy

目的分析无糖尿病视网膜病变的糖尿病性视神经病变(DON)在无糖尿病视网膜病变的糖尿病群体中的患病率。方法通过糖尿病社区筛查和糖尿病眼病门诊筛查,经免散瞳眼底照相筛选出无糖尿病视网膜病变的DON患者,分别计算社区筛查和糖尿病门诊中DON在无糖尿病视网膜病变的糖尿病群体中的患病率,并计算DON在上述两个糖尿病群体中的总患病率。结果社区糖尿病免散瞳眼底照相筛查无糖尿病视网膜病变的DON患者105例(123眼),社区无糖尿病视网膜病变的DON在无糖尿病视网膜病变的社区糖尿病患者中的患病率为6.23%;糖尿病眼病门诊经免散瞳眼底照相和荧光素眼底血管造影诊断为无糖尿病视网膜病变的DON为76例(91眼),糖尿病眼病门诊中无糖尿病视网膜病变的DON在无糖尿病视网膜病变的糖尿病眼病门诊人群中的患病率为10.36%。无糖尿病视网膜病变的DON在上述两个群体中的总患病率为7.50%。结论无糖尿病视网膜病变的DON在无糖尿病视网膜病变的社区糖尿病患者和糖尿病眼病门诊患者中的患病率较高,且其可严重损伤视力,早期和定期的糖尿病眼病筛查可及时发现DON,从而降低对患者的视力损伤。

Objective To analyze the prevalence rate of diabetic optic neuropathy（DON）in diabetic patients without diabetic retinopathy.Methods The DON patients were screened out by non-mydriatic fundus photography in the diabetes community screening and diabetes eye disease clinic screening.The DON prevalence rate among diabetic populations without diabetic retinopathy in community and diabetes clinic was calculated and the total prevalence rate in these two diabetic populations was also calculated.Results One hundred and five cases（123 eyes）were DON without diabetic retinopathy screened by community non-mydriatic fundus color photography.The prevalence rate of community DON without diabetic retinopathy was 6.23% among the community diabetic patients without diabetic retinopathy;76 cases（91 eyes）were DON without diabetic retinopathy diagnosed by non-mydriatic fundus color photography and fundus fluorescein angiography in diabetic clinic,the prevalence rate of DON without diabetic retinopathy was 10.36% among the diabetic outpatients without diabetic retinopathy.The total prevalence rate of DON without diabetic retinopathy was 7.50% among above two populations.Conclusion The prevalence rate of DON without diabetic retinopathy is higher among the community diabetic patients without diabetic retinopathy and patients in diabetic eye disease clinic.DON can seriously damage vision,early and regular diabetic eye diseases screening can timely find DON,thus reduces its damage to patient′s visual acuity.
