This Population based Prospective interventional study was carried out in 120 eyes of 120 patients of outpatient department Detailed history was taken regarding onset, duration, preceding symptoms, ocular morbidity, data related to risk factors, past illness, systemic illness if any recorded and through clinical examination along regurgitation test, fluorescent dye disappearance test, jones dye test, probing, syringing. Epiphora is most common in the age group of 40-50 years (66 patients). Prevalence of epiphora is more in common in females (70%) than males (30%). The mean period of epiphora in our study was 1.5 years ranged from 0.5 years to 3.5 years. Syringing and probing are the main tests for the investigation of epiphora and level of block in Nasolacrimal system. Our study suggests that canalicular trephination and silicone stem intubation should be considered as an alternative treatment for distal canalicular obstructions. Highest success rates were seen in dist al lower canalicular obstructions followed by distal bicanalicular obstructions and common canalicular obstructions. Complication rates are low, particularly when compared with the DCR with Jones tube placement. No correlation was found between infectious and idiopathic causes of epiphora to the surgical outcome. Eye with proximal canalicular obstruction may have increased risk of recurrence. Factors significantly associated with recurrence of epiphora during follow up of patients after surgery included proximity of block and chronicity of disease. This study identifies punctoplasty is the surgery of choice for punctal occlusion. In unicanalicular obstruction trephination with mini monaka stent has better surgical outcome. In patients with distal common canalicular obstruction bicanalicular silicone tube intubation with external dacryocystorhinostomy is the procedure of choice. In patients with nasolacrimal duct obstruction external dacryocystorhinostomy has a good surgical outcome. Distal monocanalicular obstructions have the highest degree of symptomatic epiphora relief, followed by distal bicanalicular, common and proximal obstructions.
