Figure 1.

Simplified version of the ocular fundus (left) and the model used for the eye phantom (right). Retinal vessel diameters are within 10 and 250 μm. The layer starting with the inner limiting membrane (ILM) and ending with the photoreceptor (PR) is the neural retina (NR). The retinal pigmented epithelium (RPE) is a 10-μm-thick layer. The main absorber in this layer is the melanin. The choroid (CH) is a complex 250-μm-thick structure comprising large blood vessels, melanocytes, and connective tissues including collagen. The sclera (SC) is a 700-μm-thick layer composed of collagen fibrils.
