Effect of Hemifacial Spasm on Intraocular Pressure Measurement

Table 1

Average intraocular pressure^a in the involved eyes of patients with hemifacial spasm before and after Botox injections using Goldmann applanation tonometry and noncontact air puff tonometry.

IOP	Before Botox injection	After Botox injection (at second week)	value
Goldmann	14.5 ± 1.8	14.3 ± 1.9	0.33
NCT	16.2 ± 1.5	16.2 ± 1.9	0.80

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