To review clinical data on dogs that suffered a corneal and anterior segment foreign body (CASFB) trauma and to determine the risk factors for foreign body (FB) trauma and subsequent enucleation.
Dogs with CASFB presented to the Animal Health Trust (AHT) from January 2000 to December 2012.
Clinical data for CASFB cases were compared to those available for the remaining AHT ophthalmic population over the same period. The depth of the FB trauma was divided into five categories. The type of FB and method of removal were described for each category. The degree of secondary uveitis and lens involvement was graded and correlated with subsequent enucleation.
The mean age (standard deviation) of 218 identified CASFB cases was 3.96 (2.95) years. Risk factors for CASFB trauma were dogs younger than 5 years, English Springer Spaniels, Labrador Retrievers, and working dogs. Most dogs required general anesthesia for FB removal, and hypodermic needles were the most commonly used instrument. The lens was involved in some cases with a full-thickness CASFB trauma (n = 49, 45%), but most suffered a minor lens trauma (n = 37, 76%). The lens trauma and phacoclastic uveitis were managed medically in most dogs (n = 37, 76%), and phacoemulsification was only elected as initial treatment in some dogs (n = 10, 20%). Enucleation was required overall in 6% of dogs. Statistically significant associations were found between enucleation and depth of FB trauma, degree of uveitis, and severity of lens trauma (P < 0.001).
Young dogs, English Springer Spaniels, Labrador Retrievers, and working dogs had an increased risk of CASFB trauma. Risk factors for enucleation were full-thickness FB penetration, severe lens trauma, and severe uveitis.
回顾角膜及眼前段异物（CASFB）创伤犬的临床资料，确定异物（FB）创伤及后续眼球摘除的危险因素。
2000年1月至2012年12月间就诊于动物健康信托（AHT）的患有CASFB的犬。
将CASFB病例的临床资料与同期AHT其余眼科病例的可用资料进行比较。FB创伤深度分为五类。描述了每类FB的类型和取出方法。对继发性葡萄膜炎和晶状体受累程度进行分级，并与后续眼球摘除相关联。
218例确诊的CASFB病例的平均年龄（标准差）为3.96（2.95）岁。CASFB创伤的危险因素为年龄小于5岁的犬、英国激飞猎犬、拉布拉多寻回犬和工作犬。大多数犬在取出FB时需要全身麻醉，皮下注射针头是最常用的器械。在一些全层CASFB创伤病例中晶状体受累（n = 49，45%），但大多数为轻度晶状体创伤（n = 37，76%）。大多数犬（n = 37，76%）的晶状体创伤和晶状体溶解性葡萄膜炎采用药物治疗，仅在一些犬（n = 10，20%）中选择超声乳化作为初始治疗。总体上6%的犬需要眼球摘除。在眼球摘除与FB创伤深度、葡萄膜炎程度和晶状体创伤严重程度之间发现有统计学意义的关联（P < 0.001）。
幼犬、英国激飞猎犬、拉布拉多寻回犬和工作犬发生CASFB创伤的风险增加。眼球摘除的危险因素为全层FB穿透、严重晶状体创伤和严重葡萄膜炎。
