Effect of Hemifacial Spasm on Intraocular Pressure Measurement

Table 3

Average intraocular pressure^a in the eyes of healthy volunteers with two weeks interval using Goldmann applanation tonometry and noncontact air puff tonometry.

IOP	First measurement	Second measurement (at second week)	value
Goldmann	15.2 ± 2.1	15.0 ± 1.5	0.63
NCT	16.0 ± 1.7	16.2 ± 1.5	0.54

Mean ± SD (mmHg). Paired samples t-test. NCT: noncontact tonometry; IOP: intraocular pressure.
