One-hundred and seventy-five labradoodles underwent slit-lamp biomicroscopy and direct and indirect ophthalmoscopy between January 2008 and December 2009. These examinations were performed at shows by the first author. In addition, labradoodle eye certificates from the 2008 and 2009 British Veterinary Association/Kennel Club/International Sheep Dog Society (BVA/KC/ISDS) Eye Scheme were analysed (n=260). The results of the examinations were reviewed, and all ophthalmic abnormalities were recorded. The prevalence of any abnormality was compared with that reported by the Eye Scheme and the KC during 2009 for the labrador retriever, miniature, toy and standard poodles. Multifocal retinal dysplasia (MRD) was identified in 20 labradoodles (4.6 per cent), and cataracts were identified in 16 labradoodles (3.7 per cent). The prevalence of MRD in labradoodles was significantly greater than in labrador retrievers (P<0.0001). There was no difference in the prevalence of cataract between labradoodles and labrador retrievers (P=0.4866). The results of this study suggest that MRD is a relatively common finding in the labradoodle population in the UK. Given such an apparent high prevalence of MRD, routine screening for hereditary eye disease before breeding is advised for this increasingly popular new crossbreed.
2008 年 1 月至 2009 年 12 月期间,175 只拉布拉多贵宾犬接受了裂隙灯生物显微镜检查、直接和间接检眼镜检查。这些检查是由第一作者在展览会上进行的。此外,还分析了 2008 年和 2009 年英国兽医协会/养犬俱乐部/国际牧羊犬协会(BVA/KC/ISDS)眼部计划的拉布拉多贵宾犬眼部证书(n=260)。回顾了检查结果,并记录了所有眼部异常。将检查结果的异常发生率与 2009 年眼部计划和 KC 报告的拉布拉多猎犬、迷你型、玩具型和标准型贵宾犬的异常发生率进行了比较。在 20 只拉布拉多贵宾犬(4.6%)中发现了多灶性视网膜发育不良(MRD),在 16 只拉布拉多贵宾犬(3.7%)中发现了白内障。拉布拉多贵宾犬的 MRD 发生率明显高于拉布拉多猎犬(P<0.0001)。拉布拉多贵宾犬和拉布拉多猎犬的白内障发生率没有差异(P=0.4866)。本研究结果表明,MRD 在英国拉布拉多贵宾犬群体中是一种相对常见的发现。鉴于 MRD 的明显高发生率,建议在这种日益流行的新型杂交犬种中,在繁殖前进行遗传性眼病的常规筛查。
