My information comes from Cynthia Wheeler, breed review coordinator for the book published by the Genetics Committee of the American College of Veterinary Ophthalmologists, "Ocular Disorders Presumed to be Inherited in Purebred Dogs". I quote: "I find before 6 weeks (when the tapetum begins to form) and after 10 weeks to be the best time to evaluate. Between 6 and 10 weeks, the tapetal coloring can make the rd lesions less visible."
Also, from the CERF website: http://www.vmdb.org/dx.html "Retinal dysplasia can be detected as early as 6-8 weeks on a CERF examination. However, because the size of the eye is small and young puppies are often wiggling during examination, a 6 month recheck is recommended in order for the ophthalmologist to better see the back of the eye." I agree that the puppies need to be examined at least once before the folds have a chance to heal, but I don't think that you can say for certain that dogs examined at 6-10 weeks of age are free of retinal dysplasia.
