The presence of a nondrusenoid RPE elevation: a pigment epithelial detachment (PED). If confluent drusen and a PED exist, a drusenoid PED was ruled out by the use of point to point correlation with the B scan and the OCT colour photograph. The PED can range in appearance from a large dome-shaped elevation of RPE with low reflectivity within and a visible Bruch's membrane, to an irregular and corrugated detachment that may be shallow with moderate reflectivity throughout or on the underside of the RPE. A PED was graded with or without SRF, IRF, or haemorrhage.
