Although there are several classifications of the disease according to the age of onset of the disease and the types of retinal pathology which occur, almost all forms of PRA eventually lead to complete blindness.
In some breeds of dogs, such as the Irish Setter and Norwegian Elkhound the disease begins very early in life ( as early as 6 weeks of age. )
In this type of PRA, there is a problem with the initial development of the rods and cones ( the light receptor cells in the retina ).
www.basenji.deObwohl es unterschiedliche Klassifikationen der Erkrankung ( Alter des Auftretens, Art der Netzhautpathologie ) gibt, führen fast alle Ausprägungen von PRA schließlich zur Erblindung.
In einigen Hunderassen, wie der des irischen Setter und des norwegischen Elchhund fängt die Krankheit sehr früh im Leben an ( schon ab der 6. Lebenswoche ).
Bei dieser Form von PRA gibt es ein Problem mit den hellen Empfängerzellen in der Retina.
