Marked global thinning of the peripapillary retinal nerve fibre layer in Twin 1. OCT measurements were obtained with the Topcon 3D OCT-2000™ platform (Topcon Medical Systems, Oakland, NJ). The analysis software automatically selects the appropriate normative range for the patient and the peripapillary retinal nerve fiber layer measurements (dark traces) are represented within color-coded distribution centiles (bottom panel): (i) red < 1%, (ii) yellow 1-5%, and (iii) green 5-95%.
