    Author: Wearne MJ, Beigi B, Davis G, Rose GE.
    Journal: Ophthalmology; 1999 Dec; 106(12):2325-8; discussion 2328-9. PubMed ID: 10599666.
    Abstract:
    OBJECTIVE: Retrograde intubation of canaliculi during dacryocystorhinostomy can restore canalicular patency in cases otherwise managed with bypass tubes. The surgical technique and success for this procedure are discussed. DESIGN: A retrospective, noncomparative case series with clinic or telephone interview for long-term follow-up of patients' symptoms. PARTICIPANTS: One hundred two patients who had undergone this particular lacrimal drainage surgery at Moorfields Eye Hospital between 1992 and 1997. INTERVENTION: All patients underwent a dacryocystorhinostomy and retrograde canaliculostomy while under general anesthetic. MAIN OUTCOME MEASURES: Relief or reduction of epiphora and discharge. RESULTS: One hundred twenty-three lacrimal systems of 102 patients were included. There were 53 females and 49 males, with ages at surgery ranging from 6 to 83 years (mean, 49 years). The etiology was idiopathic (30%), herpetic canaliculitis (24%), punctal agenesis (18%), and trauma (11%); less-common causes included dacryocystitis, Stevens-Johnson syndrome, eczema, and prior radiation therapy. Both upper and lower canalicular systems were involved in the majority (73%) of patients, and in 13 (11%) systems a dacryocystorhinostomy had previously been performed. The silicone tube was placed for a mean of 2 months (range, 1 week-9 months), and the mean postoperative follow-up was 8 months (range, 2-24 months). Epiphora subjectively improved in 90 (73%) of 123 systems, of which 27 (22%) of 123 were asymptomatic. In 33 systems (27%) in which epiphora persisted, 14 (11%) have undergone closed placement of a Jones canalicular bypass tube with control of symptoms. CONCLUSIONS: Retrograde canaliculostomy and intubation can spare a significant number of patients the long-term inconvenience of Jones tubes. Failure of this technique does not, however, compromise or complicate the future placement of a bypass tube.
