A 74-year-old woman complained of recurrent redness, purulent discharge, and occasional tearing of the left eye for 1 year. She has a 40-year untreated sinusitis history, with recurrent mucopurulent rhinorrhea, nasal obstruction and hyposmia, and loss of smell for 2 years. The patient\u2019s various symptoms, such as epiphora, purulent discharge, rhinorrhea, nasal obstruction, and anosmia, poorly responded to antibiotics and canaliculotomy. However, relief came from the unintentional usage of systemic corticosteroids. Canaliculitis is a rare form of inflammation involving the proximal lacrimal drainage system. Unfortunately, it is often misdiagnosed, has frequent recurrences, and fails to respond to therapy. This case highlights the importance of medical history, lacrimal examinations, and regular therapy in managing recurrent canaliculitis. For those canaliculitis patients with nasal symptoms, simultaneous treatment of nasal-related disorders should be considered.<\/jats:p>","DOI":"10.1177\/2050313x251340479","type":"journal-article","created":{"date-parts":[[2025,5,20]],"date-time":"2025-05-20T07:58:07Z","timestamp":1747727887000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Lacrimal canaliculitis related to chronic rhinosinusitis with nasal polyps: Case report and literature review"],"prefix":"10.1177","volume":"13","author":[{"given":"Chen","family":"Chen","sequence":"first","affiliation":[{"name":"Department of Ophthalmology, The First People\u2019s Hospital of Changzhou, Changzhou, Jiangsu, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yan","family":"Shen","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngology, The First People\u2019s Hospital of Changzhou, Changzhou, Jiangsu, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yanting","family":"Yang","sequence":"additional","affiliation":[{"name":"Department of Ophthalmology, The First People\u2019s Hospital of Changzhou, Changzhou, Jiangsu, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yuru","family":"Gao","sequence":"additional","affiliation":[{"name":"Department of Ophthalmology, The First People\u2019s Hospital of Changzhou, Changzhou, Jiangsu, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6784-3841","authenticated-orcid":false,"given":"Yang","family":"Bian","sequence":"additional","affiliation":[{"name":"Department of Ophthalmology, The First People\u2019s Hospital of Changzhou, Changzhou, Jiangsu, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2025,5,13]]},"reference":[{"key":"e_1_3_2_2_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00417-004-0871-5"},{"key":"e_1_3_2_3_2","doi-asserted-by":"publisher","DOI":"10.1097\/IOP.0b013e3181b8c185"},{"key":"e_1_3_2_4_2","doi-asserted-by":"publisher","DOI":"10.1159\/000310528"},{"key":"e_1_3_2_5_2","doi-asserted-by":"publisher","DOI":"10.1076\/orbi.23.1.19.28985"},{"issue":"2","key":"e_1_3_2_6_2","first-page":"73","article-title":"Canaliculitis: review of 12 cases","volume":"15","author":"Demant E","year":"1980","unstructured":"Demant E, Hurwitz JJ.
