Abstract

Aim: To investigate the influence of BTX-A on corneal parameters & tear film in patients with blepharospasm or hemifacial spasm. Objectives 1. To compare the difference between Corneal Astigmatism by using corneal topography in Hemifacial Spasm or benign essential Blepharospasm before and after injecting Botox –A. 2. To compare the differences of Tear film break up time values in Hemifacial Spasm or benign essential Blepharospasm before and after injecting Botox –A. 3. To compare the schirmer values in Hemifacial Spasm or benign essential Blepharospasm before and after injecting Botox –A. 4. To compare the difference between OSDI Scoring in Hemifacial Spasm or benign essential Blepharospasm before and after injecting Botox –A. 5. To compare the difference between JRS Severity & Frequency in Hemifacial Spasm or benign essential Blepharospasm before and after injecting Botox –A.
