To understand the pathophysiology of central serous chorioretinopathy or bullous retinal detachment in patients under systemic corticosteroid treatment. Little is understood about the mechanism of the development of serous retinal detachment.
Three patients who had developed central serous chorioretinopathy or bullous retinal detachment during systemic corticosteroid administration were examined by fluorescein angiography and indocyanine green angiography.
Indocyanine green angiography revealed dilated choroidal veins, delayed choroidal filling, intrachoroidal hyperfluorescence, and patchy hypofluorescence at or near the sites of dye leakage examined by fluorescein angiography.
The primary change caused by central serous chorioretinopathy is thought to occur in the choroid, followed by the breakdown of the outer blood-retinal barrier in the pigment epithelium, resulting in the development of serous retinal detachment.
了解全身使用皮质类固醇治疗的患者发生中心性浆液性脉络膜视网膜病变或大泡性视网膜脱离的病理生理学。目前对浆液性视网膜脱离的发病机制了解甚少。
对3例在全身使用皮质类固醇期间发生中心性浆液性脉络膜视网膜病变或大泡性视网膜脱离的患者进行了荧光素血管造影和吲哚菁绿血管造影检查。
吲哚菁绿血管造影显示脉络膜静脉扩张、脉络膜充盈延迟、脉络膜内高荧光以及在荧光素血管造影检查的染料渗漏部位或其附近出现斑片状低荧光。
中心性浆液性脉络膜视网膜病变引起的主要变化被认为发生在脉络膜,随后色素上皮中的外血视网膜屏障遭到破坏,导致浆液性视网膜脱离的发生。
