[Idiopathic retinal detachment and congenital anomaly of vitreo-retinal insertion (author's transl)].

V-shaped retinal defects which are usually parallel to the equator, develop as a congenital anomaly at the insertion of vitreous fibrils. The vitreous overlying these retinal areas is without structure. Progressive degenerative-sclerotic areas, equatorial degeneration-or lattice degeneration can develop in the region of these vitreo-retinal adhesions.
