Twenty-four consecutive patients with Hemifacial spasm and 25 age and gender-matched randomly selected eyes of healthy volunteers underwent corneal pachymetry and intraocular pressure measurements using Goldmann Applanation Tonometer and non-contact tonometer. An interval of 15 minutes was maintained between Goldmann Applanation Tonometer and non-contact tonometer measurements. Intraocular pressure measurements were performed before (during hemifacial spasm) and 2 weeks after Botox injections in Hemifacial spasm patients and in healthy volunteers without Botox injections. All the measurements with Goldmann Applanation Tonometer were carried out by a single physician while those with the non-contact tonometer were done by another physician who was masked to the results of the Goldmann Applanation Tonometer. All measurements were taken between 10:00 and 11:00 a.m.

To evaluate the effect of Hemifacial spasm on Intraocular pressure measurement.
Effect of Hemifacial Spasm on Intraocular Pressure Measurement Change
intraocular pressure measurements will be performed before and 2 weeks after Botox injections in patients with Hemifacial spasm (involved and uninvolved eyes of Hemifacial spasm both) and in healthy volunteers without Botox injections. The change between measurements will be evaluated.
Time frame: 2 week
