Heatmap and correlation matrix of all analyzed numeric parameters (A) and the respective significance levels (B). The stars symbolize statistical significance in the gradations; p ≤ 0.05 (*), p ≤ 0.01 (**), p ≤ 0.001 (***) and p ≤ 0.0001 (****). This map demonstrates that apart from axial length, there are numerous significant interdependencies and correlations between almost all clinical- and OCT-based parameters. Abbreviations: MLD: minimum linear diameter; BD: base diameter; H: height; MHI: macular hole index; DHI: diameter hole index; THI: tractional hole index; Ar: MH area, Cy: cyst area; VA: visual acuity; ns: not significant
