渗出性视网膜炎,又名Coats病,系1908年Coats描述的一种少见的外层视网膜病变,常伴有大量渗出物。他认为是由视网膜深层出血引起,故命名外层出血性视网膜炎,并将其分为三种类型:①无明显血管改变。②有明显血管改变。③有动静脉贯通。1912年Coats本人又排除第三种类型,认为是属于视网膜血管瘤病,即Von Hippel-Lindau病,此后习惯上即称上述第一、二类型为Coats病。 Exudative retinitis, also known as Coats disease, is a rare case of outer retinopathy described by Coats in 1908, often accompanied by a large exudate. He believes it is caused by deep retinal hemorrhage, so named hemorrhagic retinitis, and divided into three types: ① no significant vascular changes. ② obvious vascular changes. ③ arteriovenous. In 1912, Coats himself excluded the third type, which is considered to be retinal hemangiomatosis, Von Hippel-Lindau disease, since then habitually referred to as the first and second types of Coats disease.
