Data are expressed in micron, reported as mean ± standard deviation; thickness values are reported for the specific analyzed areas: mean, inner ring superior (S3), temporal (T3), inferior (I3) and nasal (N3); outer ring superior (S6), temporal (T6), inferior (I6) and nasal (N6); and central (C1). Statistical analysis between the two groups is also reported. Mean macular thickness is slightly increased in FEs as compared to CEs, but the difference is not statistically significant. Subfield analysis shows a retinal thickness significantly higher in the FEs in the central area (C1) and temporal inner ring (T3), lower in nasal outer ring (N6) and superior outer ring (S6). No statistically significant differences were found in the other subfield.
