R = right eye, L = left eye; IT = inferotemporal; SN = superonasal, MC = medial canthus; H = horizontal (transverse) section; C = coronal (frontal) section; S = sagittal section; IMMS = intermuscular membrane score (from 0 [evidence there is no membrane in the four quadrants] to 8 [total evidence there is a barrier to the dye spread at the supposed place where the septum lies]); diffusion score = presence of latex in the space not injected (i.e. , extraconal space); IFS = intracone filling score by latex (0 = total or massive, 1 = incomplete or partial, 2 = not at all).
