Jones lacrimal bypass tubes in children and adults

摘要

Background/aims Although a Jones tube is considered the mainstay for epiphora in patients with total blockage of the canalicular system, it has been discouraged in children for reasons of inadequate self-care and maintenance. The purpose of this study is to compare the long-term outcome of Jones tube surgery in paediatric versus adult patients. Methods Retrospective, interventional case series of a single academic institution. The medical records of all children ( 16 years old) who underwent conjunctivorhinostomy with placement of a 130 degrees angled extended Jones tube were reviewed. The outcome measures were patency and anatomical position of the tube, type and frequency of complications and subjective relief of epiphora. Results The study included 10 children (11 eyes) (range, 5.1-16.0 years old) and 102 adults (127 eyes) (range, 19.7-82.4 years old). The success and complication rate did not differ between the two age groups. Tube dislodgement and obstruction occurred in 4 (36.4%) of the paediatric tubes with an incidence rate of 6.1%/year and in 47 (37.0%) of the adult tubes with an incidence rate of 9.3%/year (p=0.3867). Two adults required routine self-irrigation of the tube. The median follow-up was 6.7 years for the children and 8.7 years for the adults (p=0.3430). Conclusion With a similar outcome profile and minimal self-care, young age is not a prognostic nor limiting factor for surgery with angled Jones tubes. Exchange with tubes of a longer length is not required during growth.
