Congenital Nasolacrimal Duct Obstruction Update Study (CUP Study): Report III. Analysis of Earlier Failed Probing without Endoscopy Guidance

Comparison of success rates of probing surgery in congenital nasolacrimal duct obstruction by age range

“…Nakayama et al reported that spontaneous resolution of CNLDO occurred after the age of 12 months in 45% of infants 7 . Nasolacrimal probing is the treatment of choice for CNLDO that does not have a spontaneous resolution [4][5][6][7] because probing, which is performed by inserting a small blunt probe into the punctum and throughout the nasolacrimal drainage system, has several advantages over more complex procedures such as short surgical time, minimal surgical manipulation, low risk of bleeding, and no need for subsequent tube removal [5][6][7][8] . However, there is no consensus about the best time for probing [1][2][3][4] .…”

“…The sensitivity and specificity of the FDDT are 100% and 85%, respectively [1][2][3][4] . Conservative treatment, which includes massaging the pouch area, is widely preferred in clinical practice due to the high chance of spontaneous opening within the first year in the treatment of CNLDO 7,8 .…”

“…Probing surgery has been advocated as the first-line treatment option with a 75-90% success rate in patients who do not improve with conservative treatment [7][8][9][10] . Alternative treatments after probing surgery have been used including silicone intubation, balloon dacryoplasty, and dacryocystorhinostomy [6][7][8][9] . However, these treatments are more invasive interventions than probing procedures.…”

“…The timing of probing is the subject of debate, and there is no definite consensus in the literature for the ideal probing time. [5][6][7][8][9] Probing surgery seems to be more successful at an early age; however, studies have reported that it has been effective at a later age [4][5][6][7][8] .…”

Success Rate of Probing in Congenital Nasolacrimal Duct Obstruction: Case Series

“…Yakın zamanda yapılmış akut dakriyosistiti olan 27 infantın değerlendirildiği retrospektif bir çalışmada ise sistemik antibiyotik tedavisi ve endoskop kılavuzluğunda sondalama iş-lemi ile ortalama 8 aylık takipte %90,4 oranında başarı elde edildiği bildirilmiştir. 31 Retrospektif tasarımı nedeniyle çalışmamızın bazı kısıtlılıkları mevcuttur. Verileri eksik olan hastaların olması hasta sayımızı azaltmıştır.…”
