[Handmann's optic nerve anomaly and "morning glory" syndrome (author's transl)].

Both "Handmann's optic nerve anomaly" and "Morning Glory Syndrome" are pronounced rearward displacements of the optic disk. The resultant peripapillary scleral staphyloma may be either the cylindrical "Handmann's optic nerve anomaly" or the funnel-shaped "Morning Glory Syndrome". The peripapillary scleral staphyloma is frequently filled to a variable extent with embryonal (Bergmeister papilla), reddish-grey tissue with a white center. The central vessels branching in the depths of the scleral staphyloma then mainly protrude as small vessels at the inner margin of the scleral staphyloma. The optic nerve anomaly is mostly surrounded (in the area of former embryonal tissue?) by circular pigmentation, depigmentation or atrophy of the chorioid of variable extent. "Handmann's optic nerve anomaly" and the "Morning Glory Syndrome" are likely to be variations of the same anomaly.
