Figure 3

 (A) Colour fundus photograph of the left eye of a 54 year old female patient shows a subfoveal green-grey lesion with minimal haemorrhage. The arrow indicates the location and direction of the optical coherence tomographic (OCT) scan. (B) OCT passing through the fovea illustrating bilaminar foveal thickness (BFT), intraretinal fluid (IRF), and subretinal fluid (SRF). BFT is the distance between the inner high reflectivity band and the inner margin of the outer high reflectivity band at the foveal centre in the presence of subretinal hyporeflective area. NFT = 473 μ and BFT = 722 μ in this scan.
