Coats病治疗的关键是破环异常扩张的视网膜毛细血管及小动脉 ,临床上常用的治疗方法有激光和冷冻。激光适用于渗出水肿较轻的病例 ,但当渗出水肿严重引起视网膜脱离时 ,激光则难以达到治疗效果 ,部分病例可通过冷凝治疗来达到治疗目的。我们观察伴有视网膜脱离行视网膜冷凝病例 The key to the treatment of Coats disease is the abnormal expansion of broken retinal capillaries and arterioles, clinically used treatment methods are laser and frozen. Laser is suitable for exudative edema cases lighter, but when the exudate edema caused by retinal detachment, the laser is difficult to achieve the therapeutic effect, in some cases by condensation treatment to achieve the purpose of treatment. We observed retinal detachment associated with retinal condensation cases
