title: Ganglion Cell-Inner Plexiform Layer, Peripapillary Retinal Nerve Fiber Layer, and Macular Thickness in Eyes with Myopicβ-Zone Parapapillary Atrophy.
abstract: Purpose. To assess the correlations of myopicβ-zone parapapillary atrophy (β-PPA) with the optic nerve head (ONH) and retina.Methods. We selected 27 myopic patients who showed prominentβ-PPA in one eye and noβ-PPA in the other eye. We studied their macula, macular ganglion cell-inner plexiform layer (mGCIPL), peripapillary retinal nerve fiber layer (pRNFL) thickness, and ONH parameters using optical coherence tomography.Results. The average of five out of six sectors and minimum values of mGCIPL thicknesses in eyes with prominentβ-PPA discs were significantly less than those of the control eyes. The results of clock-hour sector analyses showed significant differences for pRNFL thickness in one sector. In the ONH analyses, no significant difference was observed between myopicβ-PPA and control eyes. The macular thickness of theβ-PPA eyes was thinner than control eyes in all sectors. There was a significant difference between the two groups in three sectors (the inner superior macula, inner temporal macula, and inner inferior macula) but there was no significant difference in the other sectors, including the fovea.Conclusions. The myopicβ-PPA eyes showed thinner mGCIPL, parafovea, and partial pRNFL layers compared with myopic eyes withoutβ-PPA.
