The nasal endovision system or the nasal endoscopy unit is a useful addition to the oculoplastic clinic due to its prominent role in the disorders of the lacrimal sac and nasolacrimal duct. The preoperative evaluation of the nasal cavity before primary or revision, endonasal or external DCR, postoperative ostium evaluation, and monitoring of the lacrimal stents are of paramount importance. Moreover, its role in the management of failed probing has been established to look for and manage the inferior turbinate or inferior meatus-related factors responsible for the failure of previous probing(s).
