Use of Coronary Angioplasty Balloon Catheters in Dacryology
Nandini Bothra
Purpose
To discuss the use of coronary angioplasty balloon catheters in the practice of Dacryology.
Methods
Balloon dacryoplasty has been majorly used for congenital nasolacrimal duct obstructions (CNLDO) and recently for acquired NLDO. The ophthalmic dacryoplasty balloon catheters are available in limited sizes (mainly 2mm and 3mm) and are expensive. The Coronary angioplasty balloons available in various sizes from 1mm to 4mm and beyond with comparable physical properties and safety, enable its use in the various portions of the lacrimal drainage system. We used these balloons with different sizes in cases with CNLDO (2.5mm x 10mm), failed endoscopic dacryocystorhinostomy (4mm x 10mm) and punctal stenosis (1.25mm x 10mm).
Results
Coronary angioplasty balloons were used in cases with CNLDO (2.5mm x 10mm balloons) [23 eyes of 22 children, average age – 4.33 years, mean follow up – 6.17 months, anatomical and functional success – 87% cases (n = 20/23)]; for revision endoscopic dacryocystorhinostomy (4mm x 10mm balloons) [10 cases (6 failed external DCR and 4 failed endoscopic DCR) with grossly stenosed ostium in 5 (50%) cases and organized granulomas threatening the internal common opening in 5 (50%) cases, mean follow-up – 20 months, anatomical and functional success in 9 cases (90%)]; and punctoplasty (1.25mm x 10mm balloon) [pilot case – round, well dilated punctum, with direct view of the vertical canalicular mucosa]. The cost of coronary balloon catheter was approximately $60.
Conclusion
The outcomes of balloon dacryoplasty in patients with congenital nasolacrimal duct obstruction with coronary balloons catheters is comparable to that of traditional balloons and gives good outcomes in cases with revision dacryocystorhinostomy and punctal stenosis. It also offers significant economic advantage for developing nations.
