Changes To Eye Screening Advice From The British Veterinary Association (BVA) / KC
Pectinate ligament dysplasia (PLD for short, also known as goniodysgenesis) is a condition that may lead to glaucoma.
In the light of research, the BVA have reviewed the advice on how often dogs should have a gonioscopy test which assesses your dogs' eyes for evidence of PLD . The reason for this is that ophthalmologists now know that there may be changes over time in these structures (and also in the drainage angle of the eye). Previously it was thought this did not happen, hence the test was only done once-in-a-lifetime. The recommendation is now to test once every three years.
We do not know how many dogs will go on to develop glaucoma, but we do know that glaucoma is a painful and blinding condition. The Flatcoated Retriever Club of Scotland support the BVA/KC recommendation to screen dogs every three years in the future.
Please see the FCRS Goniodysgenesis article below for more about this, and a suggested breeding strategy from geneticist Aimee Llewellyn, in order to minimise the risk of breeding affected dogs.
Work is also ongoing at the Animal Health Trust to find out more about the genetics of glaucoma under the Canine Goniodysgenesis and Glaucoma project. Please visit AHT CGAG

BVA Gonioscopy Grading Scheme Pilot Project (July 2017)
The BVA Eye Panel Working Party agreed to pilot a grading scheme for Gonioscopy under the BVA/KC/ISDS Eye Scheme
At the start of the project the KC health dept. stated,
"This pilot study aims to give potential breeders the best scientific advice about reducing/eliminating primary closed angle glaucoma (PCAG)/primary angle closure glaucoma (PACG) without compromising genetic diversity.
The pilot study started July 2017 and the Eye Panel Working Party will assess its progress in November 2017. There may be minor amendments during this interim stage if any new scientific evidence emerges.
Please note that while the Gonioscopy grading scheme is being piloted, the BVA will record the grades and the Kennel Club will continue to publish the results of Gonioscopy, as either 'Clinically unaffected' or 'Clinically affected' - as is done at present. The only change to the current arrangement is that owners will have access to the grading system proposed and agreed by the Eye Panel Working Party."
