緑内障家系調査—第2報文献的考察及び家系調査に見られた緑内障の様相

Investigation of the Family Trees on Glaucoma:Part 2 : Comparison of Our Cases with Those in the References and Phase of Glaucoma Found during Our Observation of Glaucoma Families.

I．緒言

　第1報で緑内障の9家系について仔細に報告し，家系調査が，一般の集団検診に比して緑内障の早期発見には如何に確率が高く，而も実施し易い方法である事を述べると共に，今後，確実な緑内障家系の精しい報告例を多数集めるならば，原因不明の緑内障も遺伝学的立場から追求する事が出来，やがては本態解明の資ともなる事を強調した。

　今回は洋の東西で報告されている緑内障家系で，調べ得た範囲のものについて比較考案すると共に，緑内障の様相について述べて見たい。

1) Family tree No. 1 with consanguinous marriage suggested us that glaucoma might he of recessive heredity.

2) Family tree No. 4 and No. 5 impressed us that glaucoma might be of dominant here-dity.

3) None of family trees on our study sho-wed that glaucoma might be of sex-linked heredity.

4) Generally speaking, the statistics of glaucoma showed us that the glaucoma could be found most frequently at the ages of 41 to 60, but during our investigation of glau-coma pedigrees, glaucoma could be found mostly at the ages less than 40.
