Therefore, the main characteristics of macular oedema in OCT, apart from increased retinal thickness, include intraretinal spaces of reduced reflectivity, disintegration of the layered retinal structure, and usually also flattening of the central foveal depression.
Those included the presence of highly reflective dots in the inner retina corresponding with vessels on FA, presence of hyporeflective intraretinal spaces within and under the retina, blunting of the foveal pit, and presence of an area of outer and inner retina with similar reflectivity.
