要約 目的:軽症の眼瞼けいれんに対するボツリヌス毒素による治療の結果の報告。対象と方法:過去5年間にボツリヌス毒素で治療した眼瞼けいれん28人を対象とした。男性8例,女性20例であり,若倉分類で7例は軽症,21例は重症であった。VFQ-25によるアンケート調査で治療効果を判定した。結果:軽症群では全例で症状が軽快し,5例(71%)で無症状になった。重症群では無症状化はなく,61%で症状が改善,19%で症状が不変であった。VFQ-25では,両群ともに症状が有意に改善した。治療後の総合スコアは,軽症群が84.3,重症群が65.7であった。結論:眼瞼けいれんに対するボツリヌス毒素による治療では,重症者よりも軽症者で効果が高かった。
Abstract. Purpose:To report the outcome of treatment with botulinum toxin for mild and severe blepharospasm. Cases and Method:This retrospective study was made on 28 cases of blepharospasm who received treatment with botulinum toxin in the past 5 years. The series comprised 8 males and 20 females. Seven cases were diagnosed with mild and 21 cases with severe blepharospasm. Outcome of treatment was evaluated by questionnaire using VFQ-25. Results:Subjective symptoms improved in all cases with mild blepharospasm. Five cases(71%)reported absence of complaints. Subjective symptoms improved in 61% and remained unchanged in 19% of cases with severe blepharospasm. There was no case who reported absence of complaints. VFQ-25 showed significant improvement in both groups. Comprehensive score after treatment averaged 84.3 in mild cases and 65.7 in severe cases. Conclusion:Treatment with botulinum toxin resulted in better outcome in patients with mild than severe blepharospasm.
