Despite recent improvements in the care of diabetic patients, diabetic retinopathy remains the most common cause of blindness among the diabetic population. The aim of this study is to identify the incidence and severity of diabetic retinopathy among diabetic patients followed-up at the metabolic clinics of the Chang Gung Memorial Hospital in Taoyuan, Taiwan.
We investigated the retinas of diabetic patients who were followed-up at the metabolic clinics and received non-mydriatic fundus photograph from April 1994 through June 1994.
There were 694 patients with type 2 diabetes enrolled in this study. Their mean age was 56.2 +/- 11.1 years and the mean number of years since diagnosis was 5.9 +/- 5.7 years. Among them, 171 (25%) patients had diabetic retinopathy, including 109 (15.7%) background, 45 (6.5%) preproliferative and 17 (2.4%) proliferative cases. The presence of diabetic retinopathy correlated with the number of years since diagnosis of these diabetic patients (odds ratio: 1.03; p = 0.0024).
Non-mydriatic fundus photography is a good screening method for diabetic retinopathy detection. Twenty-five percent of type 2 diabetic patients followed-up at our metabolic clinics had diabetic retinopathy with background retinopathy being the most predominant. The most significant risk factor of diabetic retinopathy is the number of years since the patient was diagnosed with diabetes.
尽管近期糖尿病患者的护理有所改善，但糖尿病视网膜病变仍是糖尿病患者失明的最常见原因。本研究的目的是确定在台湾桃园长庚纪念医院代谢门诊接受随访的糖尿病患者中糖尿病视网膜病变的发病率和严重程度。
我们调查了1994年4月至1994年6月在代谢门诊接受随访并接受非散瞳眼底照相的糖尿病患者的视网膜。
本研究纳入了694例2型糖尿病患者。他们的平均年龄为56.2±11.1岁，自诊断以来的平均年数为5.9±5.7年。其中，171例（25%）患者患有糖尿病视网膜病变，包括109例（15.7%）背景性、45例（6.5%）增殖前期和17例（2.4%）增殖性病例。糖尿病视网膜病变的存在与这些糖尿病患者自诊断以来的年数相关（优势比：1.03；p = 0.0024）。
非散瞳眼底照相是检测糖尿病视网膜病变的一种良好筛查方法。在我们代谢门诊接受随访的2型糖尿病患者中，25%患有糖尿病视网膜病变，其中背景性视网膜病变最为常见。糖尿病视网膜病变最显著的危险因素是患者自诊断糖尿病以来的年数。
