1. A system for evaluating an eye of a patient from a set of OCT data comprising: a processor; and a non-transitory computer readable medium storing executable instructions comprising: a layer segmentation component configured to identify and segment a plurality of retinal layers within the set of OCT data, the plurality of layers comprising a layer of interest; a mapping component configured to generate at least one of an en face representation of the layer of interest and a three-dimensional reconstruction of the layer of interest from the segmented plurality of layers; a parameter generator configured to derive at least one parameter, representing a thickness of the layer of interest, from the at least one of the en face representation of the layer of interest and the three-dimensional reconstruction of the layer of interest; and a user interface configured to provide the determined at least one parameter to a display.
