短头犬种具有导致眼部临床体征的解剖学颅骨变化，称为短头眼综合征（BOS）。近年来，它们的受欢迎程度有所增加，但过度的选择压力导致头骨形状的极端构象，导致面部变化，可能会使这些狗的视力处于危险之中。本研究旨在分析93只短头犬样本中的眼部疾病，以更好地表征疾病复杂BOS。对短头犬进行全面眼科检查。研究的参数包括动物的性别、年龄和品种、年龄、进行的眼科检查、补充检查的结果、临床体征、眼部疾病、治疗方案及其结局。使用Microsoft Office Excel 2007®组织数据，并使用IBM SPSS Statistics 20®进行统计分析。研究群体包括93只短头犬，45只雄性（48%）和48只雌性（52%），来自不同品种：法国斗牛犬（n = 38）、西施犬（n = 22）、哈巴狗（n = 17）、英国斗牛犬（n = 5）、北京犬（n = 4）、拳击犬（n = 4）和波士顿梗（n = 3），年龄在0.2-16岁之间，平均年龄4.65岁。最常见的眼部异常是44%的动物发生角膜溃疡，36%的动物发生角膜色素沉着，25%的动物发生角膜纤维化，22%的动物发生睑内翻。普格犬角膜色素性角膜炎（53%）和西施犬角膜纤维化（36%）的发病率较高。最常见的手术方法是内眦成形术（22%）、结膜瓣成形术（10%）和电脱毛术（7%），无术后并发症。结论：这项研究有助于更好地描述疾病复杂的短头眼综合征。眼睑内翻、角膜色素沉着、纤维化和溃疡等眼部疾病的比例很高，突出了定期眼科检查和早期诊断原发性疾病的重要性。哈巴狗的角膜色素沉着发生率较高，西施犬的角膜纤维化发生率较高，这表明某些短头犬种可能易患某些眼部异常。应实施负责任的繁殖策略，以避免将异常性状不希望的遗传给后代。
Brachycephalic breeds have anatomical skull changes that are responsible for ocular clinical signs, known as the brachycephalic ocular syndrome (BOS). Their popularity has increased in recent years but the excessive pressure of selection lead to extreme conformation of skull shapes, resulting in facial alterations that can put these dogs’ vision at risk. This study aimed to analyse the ocular disorders in a sample of 93 brachycephalic dogs to better characterize the disease complex BOS. Brachycephalic dogs were submitted to a complete ophthalmological examination. The studied parameters included animal’s sex, age and breed, age, ophthalmological tests performed, results of complementary exams, clinical signs, ocular disorders, treatment protocols and their outcomes. Data were organized using Microsoft Office Excel 2007® and statistical analysis was performed with IBM SPSS Statistics 20®. The studied population included 93 brachycephalic dogs 45 males (48%) and 48 females (52%) from different breeds: French Bulldog (n = 38), Shih-Tzu (n = 22), Pug (n = 17), English Bulldog (n = 5), Pekingese (n = 4), Boxer (n = 4) and Boston Terrier (n = 3), aged between 0.2–16 years, median 4.65 years. The most frequent ocular abnormalities were corneal ulcers in 44%, corneal pigmentation in 36%, corneal fibrosis in 25% and entropion in 22% of the animals. There was a higher incidence of corneal pigmentary keratitis in Pugs (53%) and corneal fibrosis in Shih Tzus (36%). The most common surgical techniques were medial canthoplasty in 22%, conjunctival flap in 10% and electroepilation in 7% of the cases, without post-operative complications. Conclusions: This study contributed to a better characterization of the disease complex brachycephalic ocular syndrome. The percentage of ocular disorders like entropion, corneal pigmentation, fibrosis and ulcers was high, highlighting the importance of a regular ophthalmological check-up, and early diagnosis of the primary disorders. A higher incidence of corneal pigmentation was noticed in Pugs and corneal fibrosis in Shih Tzus, which suggests that some brachycephalic breeds may be predisposed to certain ocular abnormalities. A responsible reproductive strategy should be implemented to avoid undesired transmission of the abnormal traits to the offspring.
