脉络膜脱离型视网膜脱离是特殊类型的孔源性视网膜脱离，其具有发病急、治疗困难、预后不佳等特点，手术是目前主要治疗方法。糖皮质激素具有抗炎、降低血管通透性、抑制新生血管与成纤维细胞增生的作用。研究发现，激素有助于提高手术成功率，并改善患者预后的作用。但使用激素具有并发症多、可延误手术治疗时机等问题，使其应用未能普及。该文就糖皮质激素在脉络膜脱离型视网膜脱离患者中的应用时机、安全性等方面进行综述。“,”Choroidal detachment accociated with retinal detachment is a special type of retinal detach-ment,which has a rapid development and poor prognosis.Surgery is the main treatment currently.The glu-cocorticoids have the function of anti-inflammatory , reducing vascular permeability , inhibiting angiogenesis and fibroblast cell proliferation .Studies found that using steroid can improve the success rate of surgery and improve patient′s quality of life.However,it has not yet reached a consensus to use before or after surgery becauseof side effects of the drug and possible delay of the optimal time of surgery .Here is to make a review of the timing and safety of glucocorticoids in patients of choroidal detachment accociated with retinal detach-ment.
