PURPOSE:Toinvestigate the classification and the age incidence of Coats disease. METHODS:75 cases(79 eyes)of Coats disease were analysed,which were diagnosed by fundus fluorescein angiograpy(FFA)between Jan.1981 and Dec.1994. RESULTS:The patients included 59 males and 16 famales.Average age of the first presentation was 26 years old,and there were 45(60%)cases aged from 19 to 60 years old.In 5 eyes,the ophthalmoscopic examination revealed no obviously abnormal retinal blood vessel,but a number of dilated retinal vessels and microaneuryms were demonstrated by FFA. CONCLUSIONS:The autors consider that there is no essential distinction between type Ⅰand type ⅡCoats disease and it is no longer suitable to apply the traditional classification.Coats disease affects not only juvenile patients but also persons of all ages. （Chin J Ocul Fundus Dis,1996,12: 77-79）
