Table 3 Intraclass coefficient and coefficient of variance of each intraocular pressure in the sitting and supine positions

From: Evaluation of rebound tonometer iCare IC200 as compared with IcarePRO and Goldmann applanation tonometer in patients with glaucoma

Tonometer/position ICC (95% CI) CoV (%)
Sitting
 GAT 0.984 (0.979–0.988) 1.6 ± 2.2 (0.0–7.1)
 IcarePRO 0.945 (0.929–0.959) 5.0 ± 3.2 (0.0–19.4)*
 IC200-single 0.967 (0.957–0.975) 4.4 ± 2.2 (0.0–16.9)*
 IC200-continuous 0.971 (0.962–0.978) 4.1 ± 2.8 (0.0–14.9)*
Supine
 IcarePRO 0.963 (0.952–0.973) 4.6 ± 3.1 (0.0–17.2)
 IC200-single 0.987 (0.984–0.991) 3.9 ± 2.2 (0.0–10.5)
 IC200-continuous 0.984 (0.979–0.984) 3.5 ± 2.3 (0.0–13.7)
