Progressive rod cone degeneration

From Dog

Progressive rod cone degeneration (PRCD) is an autosomal-recessive genetic ocular disease characterised by degeneration of the photoreceptor cells in the retina, eventually leading to complete blindness.

This genetic disease has been reported in many breeds.

Most PRCD cases are clinically indistinguishable from other forms of progressive retinal atrophy and affected dogs often present with hemeralopia.

PRCD is a late onset form of PRA, however there is variation of the age of onset between the many breeds it affects. Variation in the time of onset is due to a combination of genetic and environmental factors.

A breed-specific PCR test is available for testing for this condition.

There is no known treatment for this condition and severely affected individual dogs often remain blind.
