TitleImprovement of Choroidal Blood Void in a Case of Acute Macular Neuroretinopathy
Accept poster if oral is not possible ?Yes
PurposeTo report a case of acute macular neuroretinopathy (AMN) which responded well to systemic corticosteroid. The clinical course and treatment results, especially the features observed by optical coherence tomography angiography (OCT-A) will be discussed along with a review of the literature.
MethodsThis was a retrospective case report. Systemically corticosteroids were administrated across three months for the AMN. The best-correct visual acuity (BCVA), as well as the color fundus, near-infrared reflectance images, optical coherence tomography (OCT), OCT-A and visual field (VF) exams were documented.
ResultsThe improvement after treatment in the patient not only could be detected by BCVA, VF and OCT but also could be noticed by OCT-A, which disclosed improvements of choroidal flow void in the choriocapillaris layer in both eyes.
ConclusionIn the present study, the choroidal flow void revealed by the OCT-A improved after systemic corticosteroid, along with the recovered of BCVA, OCT and VF defects. These findings may suggest inflammation plays a role in vascular compromise, and that steroid treatment may be beneficial to AMN patients at the acute stage.
