Abstract

Optical coherence tomography (OCT) is one of imaging technologies to diagnose ophthalmic diseases and to monitor progresses of treatments. Therefore, OCT and OCT-angiography (OCTA) have actively developed in the field of ophthalmology, and retinal phantoms for evaluation of performance of OCT and OCTA also have been studied. In this presentation, we will show methods and results of a retinal phantom that can evaluate the optical performance of OCT and OCTA. The retinal phantom not only mimicked superficial vascular networks more realistically, but also implemented retinal layers with curvature. It consists of two microfluidic channels corresponding to superficial and deep retinal vessels, two multi-layered thin films, and base plate with retinal curvature. Each was attached with oxygen plasma for 1-min and fluorinated ethylene propylene (FEP) tubes was connected to the inlet and outlet holes. We could obtain cross-sectional OCT images and en-face OCTA images using lab-made OCT system.
