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.

Complete slit-lamp biomicroscopy should rule out corneal disease (ulcers, keratitis), uveitis, or glaucoma as causes of reflex tearing. A 4-year-old Persian cat presented with chronic left-sided

Using a lacrimal cannula (e.g., 24-26 gauge), sterile saline is gently flushed through the superior punctum. Patency is confirmed if fluid flows freely from the nostril. Resistance or reflux from the same punctum indicates obstruction.
