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.

Purpose. To evaluate the effect of applied suction during microkeratome-assisted laser in situ keratomileusis (LASIK) procedure on peripapillary retinal nerve fiber layer (RNFL) thickness as well as macular ganglion cell-inner plexiform layer (GC-IPL) thickness. Methods. 89 patients (124 eyes) with established myopia range from −3.0 to −8.0 diopters and no associated ocular diseases were included in this study. RNFL and GC-IPL thickness measurements were performed by spectral domain optical coherence tomography (SD OCT) one day before LASIK and at 1 and 6 months postoperatively. Results. Mean RNFL thickness prior to LASIK was 93.86±12.17 μm while the first month and the sixth month postoperatively were 94.01±12.04 μm and 94.46±12.27 μm, respectively. Comparing results, there is no significant difference between baseline, one month, and six months postoperatively for mean RNFL (p>0.05). Mean GC-IPL thickness was 81.70±7.47 μm preoperatively with no significant difference during the follow-up period (82.03±7.69 μm versus 81.84±7.64 μm; p>0.05). Conclusion. RNFL and GC-IPL complex thickness remained unaffected following LASIK intervention.

Background/Aims. To investigate the patterns of retinal ganglion cell damage at different stages of glaucoma, using the circumpapillary retinal nerve fiber layer (RNFL) and macula ganglion cell-inner plexiform layer (GCIPL) thicknesses. Methods. In 296 eyes of 296 glaucoma patients and 55 eyes of 55 healthy controls, the correlations of mean deviation (MD) with the superior and inferior quadrant RNFL/GCIPL thickness (defined as the average of three superior and inferior sectors, resp.) were analyzed. Results. In early to moderate glaucoma, most of the RNFL/GCIPL thicknesses had significant positive correlations with the MD. In advanced glaucoma, the superior GCIPL thickness showed the highest correlation with MD (r=0.495), followed by the superior RNFL (r=0.452) (all; P<0.05). The correlation coefficient of the inferior RNFL thickness with MD (r<0.471) was significantly stronger in early to moderate glaucoma compared to that in advanced glaucoma (r=0.192; P<0.001). In contrast, the correlations of the superior GCIPL thickness with MD (r=0.452) in advanced glaucoma was significantly stronger compared to that in early to moderate glaucoma (r=0.159; P<0.001). Conclusions. The most preserved region in advanced glaucoma appears to be the superior macular GCIPL, whereas the most vulnerable region for initial glaucoma is the inferior RNFL around the optic disc.
