Fig 1.
A single scan with macular fluid and Diffuse Retina Edema.
Arrows points to the following features: a) Vitreomacular traction (VMT), b) Intraretinal Fluid (IRF); c) Subretinal Fluid (SRF), d) Hyper-reflective Foci (HRF).

(a-d) Optical coherence tomography images which demonstrate the disparity of assessments between the 2 graders.
(a) foveal line scan, with disagreement on presence of Subretinal Fluid (SRF). (b-c) scans from 1mm zone which demonstrates disagreement on presence or absence of Diffuse Retinal Edema (DRE). Both graders agreed Macular Fluid [1] was present. (d) fovea line scan which graders disagreed on presence or absence of Macular Fluid.
