人工涙道とくにJones tubeについて

Artificial Lacrimal Passage Using the Pyrex Tube (Jones)

緒言

　復旧困難な涙小管閉塞については，涙嚢・鼻涙管の通過障害併発の有無によつて，涙道の全部，あるいは涙小管だけを廃管にして，バイパスをつくる方法しかない。

Thirteen cases of obstructed lacrimal passage, consisting of 10 cases with stenosed lacrimal canaliculi and 3 cases following unsuccessful surgery for dacryocystitis, have been operated on by means of conjunctivodacryocystorhino-stomy (Jones). As a particular procedure, a polyethylene tube was left in place after recon-struction of the lacrimal passage. On the 7thpostsurgical day, the polyethylene tube is re-placed by a Pyrex tube (Jones). The Jones tube is left in situ indefinitely.

During the followup period of 5 to 24 months, a satisfactory spontaneous lacrimal drainage resulted in 12 out of the 13 thus treated cases.
