Choroidal thickness analysis in keratoconus patients | López-Jiménez A, et al. 256 Actual Med. 2021; 106(814): 252- 259 No correlation was observed between anterior segment parameters and mean subfoveal CT (M) in the KC group (Table 3). Correlation between M and: Q (r=- 0.004, p=0.408), KI (r=-0.110, p=0.601) and VIA (r=- 0.218, p=0.269) was not detected (using Pearson test). Correlations between M and KM (r=0.040, p=0.848) and pachymetry (r=-0.173, p=0.408) was neither significant (using Spearman test). The choroid is being studied profusely nowadays using SS-OCT and EDI OCT. Anatomical choroidal alterations have been identified in different inflammatory eye disorders such as: as ankylosing spondylitis, psoriasis (9), Vogt-Koyanagi-Harada syndrome( 10), Behçet´s disease Table 3. Corneal parameters in both groups. KC: keratoconus, KI: keratoconus index, KM: mean corneal curvature, Pachy :minimal pachymetry, Q: corneal asphericity, TKC: staging of KC and VIA: index of vertical asymmetry.
