視神経症を疑い，入院精査できた61症例

Sixty-one cases suspected of optic neuropathy

要約　目的：九州大学眼科外来を受診時に視神経症が疑われ，入院精査を行った症例について検討した。

対象と方法：2013年1月〜2015年12月の間に視神経症が疑われ，入院精査した61症例について，診療録をもとに後ろ向きに検討した。

結果：原因としては炎症性が最も多く，16例（26％）であった。次いで虚血性，圧迫性，遺伝性，感染性と多彩な原因を認めた。髄液検査を施行した症例は22例（36％）であった。ステロイドパルスを施行した症例は27例（44％）であった。

結論：視神経症の原因に報告と比べて年代間での差はなかった。髄液検査やステロイドパルスを施行した症例も多く，入院での精査・管理は有用と思われた。

Abstract　Purpose：To report 61 cases who were initially suspected of optic neuropathy.

Cases and Method：This retrospective study was made on 61 cases who were seen at Kyushu University Hospital during the past 3 years and who were initially suspected of optic neuropathy. The series comprised 34 males and 27 females. The age ranged from 7 to 89 years, average 51 years. All the cases were examined by magnetic resonance imaging（MRI）. Lumbar puncture was performed in 22 cases. Findings were analyzed based on clinical records.

Results：The most common underlying lesion was inflammatory in 16 cases（26％）, followed by ischemic（13％）, compression（11％）, hereditary（7％）and infectious（5％）among others. Pulsed corticsteroid therapy was performed in 27 cases（44％）.

Conclusion：There was no difference among age groups regarding the underlying cause of optic neuropathy. Hospitalization was useful in the diagnosis and treatment by enabling lumbar puncture and pulsed corticosteroid therapy.
