中心性浆液性脉络膜视网膜病变眼底近红外线成像特征

目的分析中心性浆液性视网膜脉络膜病变(central serous chorioretinopathy,CSC)患者眼底近红外线(near infrared,NIR)成像的特点。方法对26例(28眼)CSC患者应用Kowa眼底照相机进行眼底照相、新型海德堡造影系统HRA2进行NIR成像、荧光素眼底血管造影、吲哚菁绿脉络膜血管造影检查,并对结果进行分析。结果眼底照相:20眼急性CSC表现为黄斑区神经上皮浆液性脱离,2眼伴视网膜色素上皮脱离(pigmented epithelial detachment,PED);8眼慢性迁延性CSC表现为黄斑区色素脱失。FFA检查显示:20眼急性CSC均有视网膜色素上皮(retinal pigment epithelium,RPE)渗漏;慢性迁延性CSC FFA早期表现为斑驳样透见荧光,晚期可见荧光素缓慢渗漏。ICGA检查:早期20眼可见区域性脉络膜血管充盈迟缓;ICGA中期可见脉络膜血管通透性增高,呈强荧光;18眼ICGA揭示的病灶要比FFA多。PED在FFA和ICGA均表现为边界清晰的盘状强荧光。NIR检查:神经上皮层脱离区表现为椭圆形暗区,边界清晰或模糊;PED在NIR表现为边界清晰的圆形暗区;RPE损害在NIR表现为灰白色区域。结论红外线成像技术为CSC的诊断提供了一个新的无创性的检查方法,但有关CSC NIR像的特征尚需进一步总结。

Characteristics of near infrared imaging in central serous chorioretinopathy

Objective To investigate the characteristics of near infrared(NIR) imaging in central serous chorioretinopathy(CSC).Methods About 28 eyes of 26 patients with CSC were examined with fundus photography by Kowa fundus camera,Heidelberg Retina Angiography 2(HRA2) with NIR imaging,fundus fluorescein angiography(FFA) and indocyanine green angiography(ICGA).The results were anlayzed.Results Twenty eyes were with acute CSC showing serous macular neurosensory detachment and two eyes combined with pigmented epithelia...
