To describe foreign bodies (FBs) in the nasolacrimal sac of dogs, the history, and simple diagnostic and therapeutic approaches. Animals studied Fourteen dogs of different breeds, ages, and sexes were presented with unilateral dacryocystitis and had been treated without success for over 1-8 months.
Patient history, including prior treatment, was obtained from medical records. Slit-lamp examination was performed in all cases (SL 17, Kowa Company Ltd.). Jones tests 1 and/or 2 were performed in 13/14 cases. Dacryocystotomy was initiated with an incision into one canaliculus until the lacrimal sac was exposed and could be explored. After extracting the FB from the nasolacrimal sac, the surgical wound and canaliculus were left open. Aftercare included the administration of antibiotic eye drops with or without dexamethasone and systemic analgesia.
All 14 dogs were mesocephalic. Four of them were Dachshunds. Dacryocystotomy revealed plant-related FBs in all cases. The purulent discharge disappeared immediately after removal and did not recur during follow-up.
A simple dacryocystotomy is recommended for dogs with a strong suspicion of a foreign body in the lacrimal drainage system. Dacryocystorhinography appears to be an optional tool in these cases.
描述犬鼻泪管中的异物(FB)、病史以及简单的诊断和治疗方法。
14 只不同品种、年龄和性别的犬因单侧泪囊炎就诊,且在 1-8 个月以上的时间内接受过治疗但均未成功。
从病历中获取患者病史,包括既往治疗情况。对所有病例进行裂隙灯检查(SL 17,Kowa 公司)。13/14 例进行了琼斯 1 号和/或 2 号检查。泪囊切开术通过在一个泪小管上切开,直到暴露泪囊并可进行探查。从鼻泪管中取出 FB 后,开放手术伤口和泪小管。术后护理包括使用或不使用地塞米松的抗生素眼药水滴眼和全身镇痛。
所有 14 只犬均为中头型。其中 4 只为达克斯猎犬。泪囊切开术显示所有病例均存在与植物有关的 FB。取出后脓性分泌物立即消失,随访期间未再复发。
对于强烈怀疑泪道系统中有异物的犬,建议行简单的泪囊切开术。对于这些病例,泪囊造影似乎是一种可选的工具。
