Abstract

Purpose: 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. Observations: 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. Conclusions: Wide field SS-OCTA was sufficient for the diagnosis and longitudinal evaluation of retinal and choroidal occlusions without the need for dye-based angiography.
