The Pattern of Retinal Nerve Fiber Layer and Macular Ganglion Cell-Inner Plexiform Layer Thickness Changes in Glaucoma

Figure 4

Average threshold sensitivity maps of the advance glaucoma subgroups (I to V) in cross-sectional analysis. The grayscale applied is shown on the top left. With increasing disease severity, the deepening and enlargement of scotomas occurred more frequently in superior hemifield. The scotomas in both hemifields spread toward the physiologic blind spot and toward the nasal periphery in an arcuate pattern. The scotomas in superior hemifield occurred very closely to the area corresponding to the papillomacular bundle, whereas the parafoveal area of inferior hemifield was relatively spared (a). With the disease severity (I to V), superior RNFL and superior GCIPL thickness became significantly thinner (, resp.), whereas changes of inferior RNFL and inferior GCIPL were not significant (, resp.) (b and c). “X” indicates blind spot; dB = decibel.
