Unsatisfaction after cataract surgery in five cases with blepharospasm

要約　目的：両眼に白内障手術を受けたあとに強い不満を訴え，その原因が眼瞼けいれんであった5症例の報告。症例：過去18か月間に両眼への白内障手術を224例に行った。術後の屈折と視力が良好で，ほかに疾患がない148症例中，12例が強い不満を訴えた。結果：12例中5例で，当初はドライアイが原因として疑われ，ドライアイに対する治療を行った。男性2例，女性3例で，年齢は67～78歳（平均74歳）であった。A型ボツリヌス毒素による治療が奏効し，白内障手術から平均8.8か月後に眼瞼けいれんが不満の原因であると判明した。結論：白内障手術後に不満を訴える場合には，眼瞼けいれんが原因である可能性がある。

Abstract.　Purpose：To report five cases who were unsatisfied after uneventful cataract surgery and whose ultimate cause proved to be blepharospasm. Cases：A total of 224 cataract surgery were performed during the past 18 months in our institution. There were 148 cases who showed no problems about postoperative refraction or visual acuity and who were free of other diseases. Twelve out of 148 cases were not satisfied with the outcome of cataract surgery. Results：There were 5 out of 12 cases who were suspected of dry eye as the cause of complaints. The series comprised 2 males and 3 females. The age ranged from 67 to 78 years,average 74 years. These 5 cases were found to have blepharospasm. Treatment with botulinum toxin was effective in all the 5 cases,resulting in identification of blepharospasm as the ultimate cause of complaint 8.8 months after surgery. Conclusion：Blepharospasm may be present at the time of cataract surgery and may act as the cause of complaint about the outcome of uneventful cataract surgery.
