Relevance Rating: The test is unknown, there is no evidence (i.e. research) available, or it has not been evaluated yet. These tests may or may not be meaningful for these breeds


Disease Name

Test Type
Genetic Disease/Disorder
ERD is an early onset hereditary retinal degeneration characterized by retina cells being lost, leading first to problems seeing in dim light. Affected dogs are initially nightblind, but may become totally blind between 12- and 18 months of age.
Details 2
Affected dogs are initially nightblind, and become totally blind between 12- and 18 months of age. The postnatal development of their rod and cone photoreceptors is abnormal both structurally and functionally. Morphologically, rod and cone inner- and outer-segment growth occurs but appears uncoordinated. Adjacent rods become very disparate in the size and proportions of their inner- and outer segments. Subsequent to these abnormalities of development, the rods and cones degenerate, rapidly at first and later more gradually. (from Ackland 1987)
