Figure 1. — Heat maps and comparison of each retinal sublayer's thickness and the mean thickness of peripapillary retinal nerve fiber layers. (A) The comparison of each retinal sublayer's horizontal thickness is shown. Nasal TRL, NFL thickness in the inner ring is thicker than temporal thicknesses. Nasal TRL, IRL, GCC, and NFL thickness in the outer ring are thicker than temporal thicknesses. (B) The comparison of each retinal sublayer's vertical thickness is shown. Inferior TRL, IRL, GCC, and NFL thicknesses in the outer ring are thicker than superior thicknesses. (C–M) The heat maps of each sublayer in the ETDRS circle are shown. (C) The TRL thickness is shown. In the 1- to 3-mm zone, the nasal TRL is thicker than the temporal TRL. In the 3- to 6-mm zone, the thickness is different among the four quadrants, thickest at nasal, followed by inferior, superior, and temporal. (D) The IRL thickness is shown. In the 3- to 6-mm zone, the thickness differs among the four quadrants, thickest at nasal, inferior, superior, and temporal (no significant difference between superior and temporal). (E) The ORL thickness is shown. There is no difference between the ORL thickness among the four quadrants in the 1- to 3- and 3- to 6-mm zones. (F) The GCC thickness. In the 3- to 6-mm zone, the GCC thickness differs among the four quadrants, thickest at nasal, followed by inferior, superior, and temporal. (G) The nerve fiber layer (NFL) thickness is shown. In the 3- to 6-mm zone, the NFL thickness is different among the four quadrants, thickest at nasal, followed by inferior, temporal, and superior (no significant difference between at inferior and at nasal). (H) The GCL thickness is shown. No difference among the four quadrants is observed. (I) The IPL thickness is shown. In the 3- to 6-mm zone, the superior IPL thickness is thinner than other IPL thicknesses. (J) The INL thickness is shown. In the 3- to 6-mm zone, the INL thickness is different among the four quadrants, thickest at nasal, followed by inferior, temporal, and superior (no significant difference between at inferior and at nasal). (K) The OPL thickness is shown. No difference among the four quadrants is observed. (L) The ONL thickness is shown. No difference among the four quadrants is observed. (M) The RPE thickness is shown. No difference among the four quadrants is observed. (N) The peripheral thickness of GCC, ORL, IRL, and TRL are thinner than those of the foveola. (O) The peripapillary retinal NFL (ppRNFL) thickness is shown. Superior and temporal ppRNFL thickness is thicker than nasal and temporal ppRNFL thickness.
