  1. ↑ = difference increase between the two methods (GAT and DCT) after correcction: poor usefull equation, ↓ = difference decrease between two methods (GAT and DCT) after correction: usefull equation. P = intraocular pressure, provided by GAT and expressed in mmHg.
  2. In Asejczyk-Widlika et al.25 study subjects were divided in 3 groups (A, B, C) according to IOP values. In Ghee S et al.24 study subjects were divided in two groups (glaucoma suspect and glaucoma group).
