劣性硝子体網膜変性症（Goldmann-Favre）の一家系

A pedigree of Goldmann-Favre disease

緒　言

　硝子体と網膜が関連して起る疾患をHyaloido-retinal degenerationと呼称したのは，Wagner（1938）が最初である。その後，Ricci（1960）はこの疾患を遺伝形式により3型に分けた。

（1）　Idiopathic retinoschisis in young persons　with sex-linked recessive inheritance

A 23-year-old male and his 19-year-old sister, offsprings of consanguineous marriage of apparently normal parents, developed visual impairment and night blindness since adolescence. They showed fibrillar vitreous opacities, cystic macular degene-ration and atypical pigmentary retinopathies. Stereofunduscopy and slitlamp examination re-vealed the characteristic macular change to be due to a fibrous network intervening between the pre-retinal vitreous membrane and the retinal surface without causing true cystic formation. The observed fibrous network seemed to be in contact with the component of nerve fiber layer.
