小児涙道疾患の統計および考察

Statistical Investigation on Atresia of Naso-Lacrimal Ducts of Children

緒言

　小児，特に乳児の涙道疾患（主に先天性鼻涙管閉鎖）については，成書にも記載され，一般にもよく知られていてこと新しくのべ立てるほどのものでもない。しかし，すぐれた綜説記事には出会つても，多数の治験例に立つての考察は案外少ない。成書に記載された事項も必ずしも正確でなく，あいまいな記載や，誤りに近い記載も見うけられる。一方，実地医家のこの疾患の取り扱いに至つては，はなはだ消極的である。消極的にすぎることは，誤つた治療と言わざるを得ない。

　これらのことは，この疾患の症状，原因，治療がいたつて単純であるだけに，かえつて残念である。
