Functional Outcome in Primary Nasolacrimal Duct Obstruction after Successful External Dacryocystorhinostomy Surgery
Aim: To assess the functional outcomes of external dacryocystorhinostomy(DCR) surgery in symptomatic patient with primary nasolacrimal duct obstruction .
Settings and Design: Prospective, clinical interventional study
Methods: This study was conducted in 50 consecutive (50 eyes) patients of Primary Acquired Nasolacrimal Duct Obstruction admitted in a tertiary eye care centre. Functional outcome comprises of symptom improvement which include absence of epiphora, improvement in vision, routine work, occupational work, mood, embarrassment. Assessment was done by pre and post-operative questionnaires at 2 ,6 and 12 months postoperatively.. Anatomic success was assessed by Lacrimal syringing , Fluorescein dye disappearance test(FDDT) and endoscopic view of osteotomy. Statistical significance between preoperative and postoperative symptoms (Functional outcome assessment) was analysed using McNemars test
Results: Postoperatively, marked improvement in subjective symptoms i.e. difficulty in vision (93.5%), routine work (95.6%),occupational work (95.8%),mood(95%) and embarrassment (94%) was seen with anatomic success of 96%.
Conclusions: In PANDO population, symptoms bother patient significantly. However, successful DCR surgery has a beneficial effect on the patient physical and social health thus changing the quality of life of patients markedly.
