Fig. 4From: Comparability of three intraocular pressure measurement: iCare pro rebound, non-contact and Goldmann applanation tonometry in different IOP groupCorrelation between the three IOP measurement in four IOP groups. Horizontal panel a-d: correlation between NCT and iCare pro; horizontal panel e-h: correlation between iCare pro and GAT; horizontal panel i-l: correlation between NCT and GAT; low IOP group: vertical panel a, e, and i; normal IOP group: vertical panel b, f and j; moderate elevated IOP group: vertical panel c, g and k; higher IOP group: vertical panel d, h and lBack to article page
