IOP = intraocular pressure; SD = standard deviation; PDCT IOP = Pascal dynamic contour
tonometry intraocular pressure; GAT IOP = Goldmann applanation tonometry intraocular
pressure; IOPg = Goldmann-correlated intraocular pressure as measured from the Ocular
Response Analyzer; IOPcc = Corneal-compensated intraocular pressure as measured from
the Ocular Response Analyzer; IOPDOUG = Intraocular pressure after adjustment with the
correction formula described by Doughty & Zaman; IOPWHIT = Intraocular pressure after
adjustment with the correction formula described by Whitacre et al; IOPSHIM
=
Intraocular
pressure after adjustment with the correction formula described by Shimmyo et al; IOPPACH =
Intraocular pressure after adjustment based on the correction table provided with the
Pachmate DGH55 Portable Pachymeter.
