The prevalence of focal and panretinal photocoagulation and its relationship to demographic and other characteristics were examined in a population-based study in southern Wisconsin. For participants whose age at diagnosis was less than 30 years and who were taking insulin (996 persons) the prevalence rate of panretinal photocoagulation (13.9%) was higher than that of focal photocoagulation (3.6%). For those whose age at diagnosis was 30 years or older (1370 persons), the prevalence rate for panretinal photocoagulation (3.6%) was slightly higher than that of focal photocoagulation (3.0%). Seventy-two percent of eyes of younger onset and 45% of eyes of older onset persons that had received panretinal photocoagulation treatment were found to have incomplete regression of retinal new vessels, and in approximately half of these eyes severe proliferative retinopathy (Diabetic Retinopathy Study High Risk Characteristics [DRS-HRC]) was present. Among eyes with DRS-HRC, 55% were found to be untreated.
在威斯康星州南部的一项基于人群的研究中，对局部和全视网膜光凝的患病率及其与人口统计学和其他特征的关系进行了检查。对于诊断时年龄小于30岁且正在使用胰岛素的参与者（996人），全视网膜光凝的患病率（13.9%）高于局部光凝（3.6%）。对于诊断时年龄为30岁或以上的参与者（1370人），全视网膜光凝的患病率（3.6%）略高于局部光凝（3.0%）。在接受全视网膜光凝治疗的年轻发病者的眼中，72%发现视网膜新生血管未完全消退，在这些眼中约一半存在严重的增殖性视网膜病变（糖尿病视网膜病变研究高危特征[DRS-HRC]）。在患有DRS-HRC的眼中，55%未接受治疗。
