Retinale Dysplasie (OSD) – Labrador Retriever
Retinal dysplasia (OSD) - Labrador Retriver*
General description
Retinal Folds, also called Retinal Dysplasia (RD) can be associated with the syndrom OculoSkeletal Dysplasia(OSD). Clinical signs of OSD are skeletal malformations comprising shortened limbs (dwarfism) as well as blindness at early age. Blindness results from a partial or complete detachment of the retina and cataract due to a generalized malformation of the retina.

Detailed description
Retinal Folds, also called Retinal Dysplasia (RD), is observed in many dog breeds without any pathological consequence. However in the Labrador Retriever breed as well as in Samoyeds, Retinal Folds can be associated with a more severe syndrom, the OculoSkeletal Dysplasia (OSD). Clinical signs of OSD are skeletal malformations comprising shortened limbs (dwarfism) as well as blindness at early age. Blindness results from a partial or complete detachment of the retina and cataract due to a generalized malformation of the retina. The mode of inheritance is still not fully understood but an autosomal-dominant trait with incomplete penetrance is assumed.
