家族性先天性眼筋麻痺症例

Familiar congenital ophthalmoplegia

　先天性外眼筋運動障害は，1781年WrisbergOlbers等により報告されて以来，多数の報告があるが，家族性先天性眼筋麻痺は数少く，本邦に於ける文献上記載の明らかなものは，鈴木氏（1925），中野氏（1948），斎藤氏（1954），大石，益田氏（1954）等の僅か四家族にすぎない。最近私達は姉弟にあらわれた症例を観察したので，その眼球運動を映画で供覧し，本症の本邦に於ける文献的考察をも含めて報告したいと思う。

Familiar congenital ophthalmoplegia is uncommon in Japan. The authors reported cases of sister and brother with congenital ptosis who showed abnormal ocular movements.

Case 1, a female aged 11 years, and Case 2, a male aged 10 years, the visual acuity of the sister was r. : 0.08 (0.6 ×-3.5D. ),

1:0.3 (0.8 × -3.5D.) and that of the brother was r. : 0.7 (1.0 × -0.5D. )

1:0.7 (0.8 × -0.5D.). They had not specific finding with internalmedical examinations. They had disturbances of accommodation (1/3~1/4 of normal value). The ocular move-ments were very limited in all directions, especially on elevation.
