Abstract

Recent clinical studies have shown that abnormal retinal blood is associated with many ocular diseases such as age-related macular degeneration, glaucoma, and diabetic retinopathy. Several ocular imaging techniques have been developed to measure retinal blood flow both invasively and non-invasively, including optical coherence tomography angiography (OCTA), erythrocyte mediated angiography (EMA), laser speckle imaging (LSI) and adaptive optics - scanning laser ophthalmoscopy (AO-SLO). Here we present a simple, compact, well-controlled clinical flow phantom model which allows flow evaluation across several techniques to aid in the clinical diagnosis of ocular diseases with abnormal blood flow.
