To quantify the thickness of the inner retinal layers in the foveal pit where the nerve fiber layer (NFL) is absent, and quantify changes in the ganglion cells and inner plexiform layer. Pixel-by-pixel volumetric measurements were obtained via Spectral-Domain optical coherence tomography (SD-OCT) from 50 eyes of Parkinson disease (PD) (n = 30) and 50 eyes(More)
Purpose. To quantify interocular asymmetry (IA) of foveal thickness in Parkinson disease (PD) versus that of controls. Design. Prospective case-control series. Methods. In vivo assessment of foveal thickness of 46 eyes of 23 PD patients and 36 eyes of 18 control subjects was studied using spectral domain optical coherence tomography (SD-OCT). Inner versus(More)
