Cat Blocked Tear Duct -

A 4-year-old Persian cat presented with chronic left-sided brownish ocular discharge. Schirmer tear test and corneal staining were normal. Fluorescein dye failed to reach the left nostril after 15 minutes. Nasolacrimal flushing with saline encountered mild resistance, followed by reflux of mucoid debris. No foreign body or mass was seen on skull CT. The cat was diagnosed with chronic idiopathic partial obstruction. Treatment consisted of weekly ductal flushing under sedation and topical antibiotic-steroid ointment for 4 weeks, resulting in decreased discharge. The owner was advised of possible recurrence.

Epiphora is a common presenting complaint in feline veterinary practice. While differential diagnoses include excessive tear production (e.g., reflex tearing due to corneal ulcers or uveitis) or poor eyelid conformation (e.g., entropion), a significant proportion of cases are attributed to obstruction of the nasolacrimal drainage system. The condition can be congenital, often seen in brachycephalic breeds, or acquired secondary to trauma, inflammation, or neoplasia. Chronic obstruction can lead to mucoid discharge, bacterial dacryocystitis (inflammation of the lacrimal sac), and discomfort. This paper aims to provide a comprehensive overview of NLDO in cats, equipping clinicians with the knowledge to diagnose and manage this condition effectively.
