To determine the incidence, etiology, and concurrent ophthalmic findings in small breed dogs that presented with cataracts.
Five hundred and sixty-one small breed dogs (942 eyes) were presented to the Veterinary Medical Teaching Hospital of Seoul National University between July 2002 and December 2007 with cataract.
The medical records of small breed dogs with cataract were reviewed. The reason for presentation, cataract duration, bilaterality, breed, gender, age, vision, etiology, stage of cataract development, concurrent ophthalmic findings, IOP, ocular ultrasonography findings, and scotopic electroretinography (ERG) findings were investigated.
The most frequently presented breeds were the Miniature/Toy Poodle (n = 112, 20.0%), Yorkshire Terrier (n = 110, 19.6%), and Shih Tzu (n = 95, 16.9%). The Miniature/Toy Poodle showed a significantly higher odds ratio for cataract formation (2.6). The proportion of female cataract patients was significantly higher than that of male cataract patients in the overall population (P < 0.05). The Miniature/Toy Poodles had significantly higher numbers of females affected with cataract (P < 0.01). The mean age for cataract formation was 8.3 +/- 3.9 years. The mean age at onset in the Miniature/Toy Poodle and Yorkshire Terrier was significantly higher, whereas that in the Miniature Schnauzer group was significantly lower (P < 0.0001). Clinical signs related to lens induced uveitis had a tendency to increase with cataract progression (P < 0.05). There were no significant differences in the b-wave amplitude for mixed rod cone response by stage (P = 0.137).
Small breed dogs with cataracts had characteristics with regard to age of onset and gender distribution, depending on the breed.
确定患有白内障的小型犬的发病率、病因及并发的眼科检查结果。
2002年7月至2007年12月期间，561只小型犬（942只眼）被送至首尔国立大学兽医学院教学医院，均患有白内障。
回顾患有白内障的小型犬的病历。调查就诊原因、白内障持续时间、双侧性、品种、性别、年龄、视力、病因、白内障发展阶段、并发的眼科检查结果、眼压、眼部超声检查结果及暗视视网膜电图（ERG）检查结果。
最常出现的品种是迷你/玩具贵宾犬（n = 112，20.0%）、约克夏梗犬（n = 110，19.6%）和西施犬（n = 95，16.9%）。迷你/玩具贵宾犬患白内障的优势比显著更高（2.6）。总体人群中，雌性白内障患者的比例显著高于雄性白内障患者（P < 0.05）。迷你/玩具贵宾犬中受白内障影响的雌性数量显著更多（P < 0.01）。白内障形成的平均年龄为8.3±3.9岁。迷你/玩具贵宾犬和约克夏梗犬的平均发病年龄显著更高，而迷你雪纳瑞组的平均发病年龄显著更低（P < 0.0001）。与晶状体诱导性葡萄膜炎相关的临床症状有随白内障进展而增加的趋势（P < 0.05）。不同阶段混合视杆视锥反应的b波振幅无显著差异（P = 0.137）。
患有白内障的小型犬在发病年龄和性别分布方面具有因品种而异的特点。
