Rhinogenic Retrobulbar Neuritis, Oculomotor-Abducens Paralysis and Ocular Involvement in Parasinusitis of Dental Origin

緒言

　鼻性球後視神経炎はOnodi,A．^1）（1904）により"Die Sehstörungen und Erblindung nasa—len Ursprungs,bedingt durch Erkrankungender hinteren Nebenhöhlen"と題して論ぜられて以来，幾多の迂余曲折を経た疾患である。

　本邦においては1925年増田教授（鼻副竈疾患と眼との関係），石原教授（眼と鼻副竈との関係）により日本耳鼻咽喉科学会で宿題報告された。

Rhinogenic retrobulbar neuritis can be clas-sified, in the order of severity of the condition, into : (1) those simulating orbital apex syndro-me, (2) those accompanied by choked disc, (3) those with central scotoma which disappearsfollowing surgery on paranasal sinuses and (4) those with 'floating' sensation curable by similar surgery. Oculomotor and/or abducens paralysis mayalso develop as complications of paranasal diseases processes inclusive of those of dental origin.

The rhinogenic retrobulbar neuritis is amena-ble to cure through radical surgery of involved paranasal sinuses and the bony optic canal.
