Influence of a New Software Version of the RTVue-100 Optical Coherence Tomograph on Ganglion Cell Complex Segmentation in Various Forms of Age-related Macular Degeneration

Purpose: Previously, we have shown that age-related macular degeneration (AMD) influences glaucoma classification with the ganglion cell complex (GCC) parameters of the RTVue-100 optical coherence tomograph (RTVue-OCT) in nonglaucomatous eyes. Now, we reevaluated the influence of AMD on GCC image …
