Multifocal retinal arterial occlusions and choroidal infarctions due to embolic triamcinolone acetonide (TA) administered during a septoplasty were imaged using swept source OCT angiography (SS-OCTA) to demonstrate the utility of this imaging modality for the diagnosis and longitudinal follow-up of retinal and choroidal vascular diseases.
A 37-year-old man presented with vision loss in his left eye upon awakening from a left-sided septoplasty during which TA was injected. Examination of the left eye demonstrated retinal whitening in the macula, white material in the distal lumen of retinal arterioles, and multifocal hypopigmented choroidal lesions. SS-OCTA imaging showed the absence of detectable flow in areas of retinal and choroidal whitening. Corresponding B-scans demonstrated hyperreflective material, thought to be embolic TA, within the retinal vessels and inner choroid.
Wide field SS-OCTA was sufficient for the diagnosis and longitudinal evaluation of retinal and choroidal occlusions without the need for dye-based angiography.
使用扫频源光学相干断层扫描血管造影（SS-OCTA）对鼻中隔成形术期间注射的栓塞性曲安奈德（TA）导致的多灶性视网膜动脉阻塞和脉络膜梗死进行成像，以证明这种成像方式在视网膜和脉络膜血管疾病诊断及纵向随访中的实用性。
一名37岁男性在接受左侧鼻中隔成形术并注射TA后醒来时出现左眼视力丧失。左眼检查显示黄斑区视网膜变白、视网膜小动脉远端管腔内有白色物质以及多灶性色素减退的脉络膜病变。SS-OCTA成像显示视网膜和脉络膜变白区域无可检测到的血流。相应的B扫描显示视网膜血管和脉络膜内层有高反射物质，推测为栓塞性TA。
宽视野SS-OCTA足以对视网膜和脉络膜阻塞进行诊断和纵向评估，无需基于染料的血管造影。
