Swept-Source OCT En Face Imaging of Paravascular Inner Retinal Defects

Widefield swept-source optical coherence tomography angiography (SS-OCTA) was performed on eyes with paravascular inner retinal defects (PIRDs) and the morphological alterations of PIRDs were described. Patients with PIRDs were imaged using 12 mm × 12 mm SS-OCTA scans. En face structural and angiographic images of the superficial retinal layers were reviewed along with retinal thickness maps. SS-OCTA en face structural images identified dark, scalloped regions along major retinal veins that corresponded to PIRDs on B-scans. The authors concluded that imaging with both structural and angiographic en face OCT was useful for the diagnosis and monitoring of patients with PIRDs. [.
