Optical Coherence Tomography Angiography Findings in Branch Retinal Arterial Occlusion Associated to Uveitis
Purpose
To describe Optical Coherence Tomography Angiography (OCTA) findings in eyes with branch retinal artery occlusion associated with posterior uveitis.
Methods
This was a retrospective case series of four young women who presented BRAO associated with active posterior uveitis. After comprehensive ophthalmic examination, they were evaluated using fluorescein angiography (FA), swept-source Optical Coherence Tomography (SS-OCT), and OCTA.
Results
Four eyes of four women in their thirties showed BRAO secondary to IRVAN syndrome, acute toxoplasmosis chorioretinitis, CMV retinitis, and Rickettsial retinitis. Fundus examinations showed sectorial areas of retinal whitening adjacent to active retinal lesions. FA revealed slow perfusion of the affected arterial branch in three of the cases and no perfusion in one. Respectively, OCTA showed a positive flow in the occluded artery in three eyes and no flow in one eye. Additionally, in all eyes, OCTA exhibited loss of microvasculature in the superficial and deep retinal capillary plexuses which extension was proportional to the area of arterial occlusion.
Conclusion
OCTA imaging provides a detailed view of the retinal microvasculature in uveitis-associated retinal arterial occlusion. It also allows non-invasive monitoring of vascular flow in the affected arterial branch.
