[Differential diagnosis of hereditary vitreoretinal degenerations ]

Vitreoretinal degenerations constitute the main cause of manifestation of an amotio retinae during youth. Seven different hereditary forms can be distinguished. For the individual types, characteristic or obligatory symptoms can be postulated. In this connection, five main symptoms of hereditary vitreo-retinal degenerations are presented: (1) foveal retionoschisis, (2) "white plains", (3) peripheral retinoschisis, (4) vitreal strands with insertion on the retina, (5) peripheral band-shaped vitreoretinal degeneration.
