Subjective outcome and quality of life following external dacryocystorhinostomy

PURPOSE: To assess the patient reported outcome and quality of life in post external dacryocystorhinostomy operated patients. METHODS: A prospective questionnaire based study was carried out on 112 patients diagnosed with chronic dacryocystitis who underwent external dacryocystorhinostomy in the department of Orbit and Oculoplasty at a tertiary eye hospital in South India. RESULTS: We included 112 cases in our study. Mean (SD) of the age of patients was 48.03 (12.79) years and ranged from 7 to 72 years of age. 44 (39.3%) patients were males and 68 (60.7%) were females. All cases had subjective symptoms of tearing, pain and swelling at baseline which were relieved by post-operative 3 in all cases. The mean (SD) best corrected visual acuity was 0.28 (0.39) at baseline and 0.25 (0.37) at postoperative 3 (p < 0.001). All four parameters studied in the GBI questionnaire - total mean GBI (32.22 vs 48.86, P < 0.001), general subscale (31.21 vs 44.08, P < 0.001), social health (46.28 vs 61.01, P < 0.001), physical outcome (22.17 vs 55.80, P = 0.0001) scores showed significant improvement from 1 vs 3 months post DCR. CONCLUSION: The GBI questionnaire is an effective tool for assessing patients’ quality of life following DCR. External DCR can not only produce a successful anatomical outcome but also bring about a measurable improvement in subjective symptoms and quality of life among patients with symptomatic NLDO.
