Abstract :
Purpose: To compare the benefits and complications of External dacryocysto rhinostomy (EXDCR) with
Silicone tube (ST) intubation in anatomical primary acquired naso lacrimal duct obstruction (APANDO)and
functional primary acquired naso lacrimal duct obstruction(FPANDO) patients.
Materials and Methods: Patients with epiphora/discharge/mucocele are grouped into group A
(APANDO) and group B (FPANDO) based on diagnostic probe test, positive syringing and Fluorescein
Dye Disapearance (FDD) test. Both group underwent EXDCR with ST intubation. Patients were evaluated
for subjective and objective resolution of epiphora/discharge/mucocoele, complications and subjective
satisfaction at the end of 6 months.
Result: There were 23 patients each in group A and group B and no difference in demographic and laterality
of eye involvement. Epiphora was common presentation in FPANDO (91%) and discharge in APANDO
(57%). (P =0.01). The success rate is 78.3% (18/23) in group A and 86.9% (20/23) in group B and the
difference is not significant (P=0.69). Tube related complications are high in group B 82.6% (P = 0.01)
and inflammation related complications in group A 61.2% (P=0.49). In group A 82.6% (19/23) and group
B 73.9% (17/23) were satisfied with the procedure (P =0.72). Tube related complication and additional
financial burden are the main factors for dissatisfaction in group B (P= 0.72)
Conclusion: Use of silicone tube does not alter the success rate of EXDCR in APANDO and FPANDO.
Preoperative counseling and eye health educations are very important before doing such procedure on rural
population.
