          Abstract

          OBJETIVO: Determinar a variação da ceratometria em olhos de pacientes portadores de espasmo hemifacial submetidos a tratamento com toxina botulínica. MÉTODOS: Foram incluídos 18 pacientes portadores de espasmo hemifacial que foram submetidos ao exame oftalmológico completo, além da topografia corneana e Orbscan previamente à aplicação de toxina botulínica tipo A e 1 mês após o procedimento. RESULTADOS: Não houve diferença estatisticamente significante entre a ceratometria encontrada pela topografia corneana ou diferença no BFS ("best fit sphere") anterior e posterior e índice de Roush avaliados pelo Orbscan nos olhos acometidos pelo espasmo em relação ao olho contralateral quando comparados antes e após o procedimento. CONCLUSÃO: Neste estudo, não encontramos diferença entre olhos com espasmo hemifacial e olhos sem essa condição quando avaliados a ceratometria, o índice de Roush e o BFS corneano antes e após tratamento.

          PURPOSE: To determine the corneal keratometric variation in patients' eyes with unilateral hemifacial spasm which underwent treatment with botulinum toxin and set against control group. METHODS: Eighteen patients with hemifacial spasm were submitted to complete ophthalmologic exam, corneal topography and Orbscan previously botulinum toxin application and one month afterwards. They were evaluated for keratometry, BFS (anterior and posterior) and Roush value. RESULTS: There were no statistical differences between eyes with hemi facial spasm and normal eyes related to keratometric values by topography and in the parameters evaluated by Orbscan as Roush and best fit sphere (anterior or posterior) prior to or after treatment with botulinum toxin. CONCLUSION: This study has not shown statistical difference between the corneal curvatures when compared eyes with hemi facial spasm with the opposite normal eyes.
