摘要Coats病以视网膜毛细血管扩张伴大量脂质渗出为特征，可导致视网膜脱离和新生血管性青光眼等严重并发症。Coats病一般独立存在，亦可在其他遗传代谢性疾病及综合征中发现Coats样视网膜病变的合并存在。伴发其他疾病的Coats样视网膜病变与典型Coats病有着很多不同，如无年龄性别差异、可双眼发病、进展迅速、部分有明确的遗传相关因素等。其中，视网膜色素变性和面肩肱型肌营养不良等遗传代谢性疾病合并Coats样视网膜病变的部分患者可分别有CRB1基因和4号染色体的4q35区等变异。深入了解与遗传代谢性疾病及综合征相关的Coats样视网膜病变临床特征，探讨两者之间的可能关系可为分析Coats病病因提供更多思维路径。

abstractsCoats disease is a relatively rare and idiopathic disorder characterized by retinal telangiectasia and massive intra-retinal and (or) sub-retinal lipid accumulation, resulting in complications including retinal detachment and neovascular glaucoma. Previous reports have revealed that Coats disease can be associated with other disorders, especially some inherited diseases, such as retinitis pigmentosa (RP) and facioscapulohumeral muscular dystrophy (FSHD). Coats disease associated with other inherited disorders is generally called Coats-like retinopathy, which has some unique features that differs from the classic Coats disease, for example there is no sex and age preference, more bilateral cases, more severe cases and more genetic factors involved. Patients of Coats-like retinopathy with RP and FSHD may have mutations in Crumbs homologue gene 1 and D4Z4 genes.
