Six dogs were diagnosed with punctal stenosis following the long‐term use of topical neomycin‐polymyxin B‐dexamethasone ( NPD ). All patients were initially presented for ophthalmic diseases requiring ongoing anti‐inflammatory therapy. Five of the 6 dogs had previously or concurrently been treated with topical anti‐inflammatory medications other than NPD . One patient exclusively received topical NPD prior to the diagnosis of punctal stenosis. The onset of punctal stenosis following therapy with NPD was variable among patients, ranging from 4 months to over 1 year. Diagnosis of punctal stenosis was made based upon the presence of epiphora and visualization of fibrotic tissue over the nasolacrimal puncta.
