Memory guide way of lacrimal duct circular catheter for congenital nasolacrimal duct obstruction

Abstract

Objective To develop a kind of domestic congenital nasolacrimal duct obstruction treatment.Methods Reviewed 35 cases and eye successively in Xinjiang Urumuqi autonomous region in the 474th hospital of PLA army ophthalmic center after a diagnosis of congenital nasolacrimal duct obstruction (CNLDO) of children,they were first in other hospital or outpatient service in our hospital to conservative treatment,pressure lacrimal duct flushing and/or lacrimal duct agent through law,follow-up of 3-16 months,in the treatment of invalid cases in our hospital eye hospital,under general anesthesia to take a new and unique treatment-special lacrimal duct probe lacrimal duct general agent in memory steel core under the guidance of upper and lower lacrimal duct ring into super soft silicone tube operation.Were followed up for 6 to 24 months,to overflowing with tears and purulent secretion disappear completely cure for standard.Results The operation method was used to treat 35 cases with cure rate 91.7％; 3 eye still had a few tears,along with purulent significantly reduce; 1 eye for preoperative had formed lacrimal sac fistula,three weeks after treatment when reviewed again from acute dacryocystitis,there were a large number of purulent secretion,take timely demolition of lacrimalduct circular catheter and systemic adequate application of antibiotic and eye local point with antiphlogistic eye drops,inflammation could be able to control.Conclusions The surgical method to treat in the young child CNLDO is a kind of home,our eye center independent fish out of the way of operation,safe and reliable,and has good curative effect,simple,low cost,can be in hospital at all levels widely develops,is worthy to be popularized.
