Purpose: To assess the quality of vision (QOV) of patients with chronic dacryocystitis and explore the impact of endoscopic dacryocystorhinostomy (En-DCR) on patients' QOV, with the aim of increasing clinicians' attention to the potential QOV changes in patients with chronic dacryocystitis.
Patients and methods: Chronic dacryocystitis patients who attended the Department of Oculoplastics, Zhongshan Ophthalmic Center, Sun Yat-sen University from January 2022 to June 2022 and had En-DCR were included. The QOV was evaluated preoperatively and postoperatively using the Quick-contrast sensitivity function test (qCSF) and the OPD ScanIII comprehensive visual quality analyser, and the contrast sensitivity function (CSF), higher-order aberrations (HOAs), and modulation transfer function (MTF) data were recorded.
Results: Thirty-eight patients with chronic dacryocystitis were included. QOV analysis of those with monocular chronic dacryocystitis revealed that HOAs were significantly higher in affected eyes than in contralateral eyes (P < 0.05), and CSF and MTF were significantly lower in affected eyes than in contralateral eyes (P < 0.05). One month after En-DCR, patients' HOAs, CSF, and MTF were significantly improved (P < 0.05), and there was no statistically significant difference in the effect of intraoperative combined silicone intubation versus no intubation on QOV (P > 0.05).
Conclusion: Chronic dacryocystitis can significantly affect the QOV of patients. Successful En-DCR significantly improves the CSF, HOAs and MTF, which can effectively improve the QOV.
