ABSTRACT

AIM: To investigate the effect of unilateral endoscopic dacryocystorhinostomy on binocular surface indexes.METHODS: Totally 45 cases with monocular primary acquired nasolacrimal duct obstruction(PANDO)who successfully underwent endoscopic dacryocystorhinostomy between 1 December 2022 and 31 July 2023 were enrolled in the study. Ocular surface indexes, including the non-invasive tear break-up time(NIBUT), Sjögren's International Collaborative Clinical Alliance ocular staining score(SICCA OSS), Korb score of lid wiper and Schirmer test scores, were collected preoperatively and at 0.5, 1 and 3 mo post-operatively. Subsequently, various indexes were compared at each time point between the operated and healthy eyes pre- and post-operatively.RESULTS: There was no significant differences between operated and healthy eyes in NIBUT, SICCA OSS, Korb scores and Schirmer test(all P>0.05). Furthermore, the Korb scores of operated eye at 0.5, 1 and 3 mo post-operatively were significantly lower than the preoperative value(P=0.034, 0.044, 0.027). Moreover, the Schirmer test score of the operated eye at 1 mo post-operatively was significantly lower than the preoperative value(P=0.0461).CONCLUSION:After a successful endoscopic dacryocystorhinostomy, tear drainage is restored, however, ocular surface damage worsens. These changes typically peak at 1 mo post-operatively before gradually improving.
