Retinal images technology such as optical coherence tomography (OCT), OCT-angiography (OCTA) and fluorescein angiography (FA) are an important for diagnosing eye diseases. As retinal imaging technology continues to evolve, standard test methods and optical phantoms for demonstrating image quality and performance also need to be developed and advanced. We used mixture solution of polydimethylsiloxzne (PDMS) and different titanium dioxide (TiO2) to develop a more realistic retinal phantom. The retinal phantom consists of two multilayer membranes, a base plate with retinal curvature, and three microfluidic channels. In addition, we developed retinal phantom for fluorescence imaging using micro-fluorescence beads. We could obtain OCT, OCTA, and fluorescence images.
