Marilyn T Posted December 21, 2007 Report Share Posted December 21, 2007 What is the purpose of doing a Cerf eye exam on a puppy if both parents are DNA normal for Cea, and are cerf'd yearly at the Finals? Just curious! Quote Link to comment Share on other sites More sharing options...
Lenajo Posted December 21, 2007 Report Share Posted December 21, 2007 What is the purpose of doing a Cerf eye exam on a puppy if both parents are DNA normal for Cea, and are cerf'd yearly at the Finals? Just curious! CERF exams cover more than CEA, they also examine for injury, as well other genetic diseases and disorders that can occur. For pup it's part of the pre-sale/pre-training exam for me. Things a CERF exam is looking for (genetic and congenital) are: Entropion Ectropion Distichiasis Ectopic cilia Eury/Macroblepharon Third Eyelid: Cartilage anomaly/eversion Prolapsed gland Cornea: Corneal dystrophy-epithelial/stromal Corneal dystrophy-endothelial Inherited/Pannus Exposure/Pigmentary Keratitis Iris: Iris/Ciliary Body Cyst Iris Coloboma Persistent pupillary membrane iris to iris Persistent pupillary membrane all others Iris Hypoplasia Lens: Cataract*significance unknown Vitreous: Persistant hyloid artery Vitreous degeneration syneresis Vitreous degeneration ant chamber Fundus: Retinal dysplasia-folds Choroidal hypoplasia Staphyloma/Coloboma Retinal hemorrhage Micropapilla CERF exams also track disease within breeds so a problem can be addressed by the breed clubs according to signficance.

Marilyn T Posted December 21, 2007 Author Report Share Posted December 21, 2007 And all these are possible on a 7 week old puppy? The reason I ask, is prior to DNA testing, I tested all my babies I purchased or raised before 12 weeks to catch the go normals. The Opthamalogist acted like I was nutty but took my money. I am expecting a litter in 10 days from two normal DNA individuals, and was surprised to hear of someone else cerfing all the puppies anyway.

I am expecting a litter in 10 days from two normal DNA individuals, and was surprised to hear of someone else cerfing all the puppies anyway. I have no idea if all are possible, but I have seen mild entroprian and iris colobomas in another closely related breed at that age. So far all the BCs I've looked at at that age are normal, and I hope it stays that way. I would be reluctant not to check - both for buyers and for myself. Some opthal. vets are relucatant to formally "CERF" pass the pups at that age, but they will do the exam and fill out the form. Which is all I want myself. If all you are worried about is CEA then don't do it. Quote Link to comment Share on other sites More sharing options...
Bill Fosher Posted December 22, 2007 Report Share Posted December 22, 2007 If all you are worried about is CEA then don't do it. And in a seven week old puppy, you're not likely to be looking for anything else. I would go as far as to say that as a breeding tool in Border collies the opthalmic exam is pretty much done. There's nothing regarding CEA that the exam will tell you that the optigen test won't, and you can learn a whether a dog is an unaffected carrier from the DNA test; something the eye exam can't tell you.
