[Optic disc pit-associated maculopathy and iris-retinochoroidal-coloboma - a rare combination].

Kranenburg's syndrome is defined as central serous detachment associated with an optic disc pit. We report the interesting and very seldom combination of Kranenburg's syndrome and iris-retinochoroidal-coloboma. Reattachment was achieved after vitrectomy, peeling of epiretinal membranes, laser coagulation adjacent and temporal to the optic disc and gas endotamponade. Coincidence of this syndrome with an iris-retinochoroidal-coloboma is extremely rare. Both coloboma and optic disc pit are based on closure defects during week 6 of embryogenesis.
