Randomized, Double-Blind, Controlled Study to Evaluate the Effect of Vidian Nerve Cauterization on Lacrimation

Abstract

The significant advantage of preservation of the SPG function is justified by Schirmer's test, although the effect did not appear to be comparable with the clinical manifestations evaluated by OSDI at 30 days. Nevertheless, the preservation of distal stump from preventive cauterization can still offer better eye ball moisture in the early evaluation of DES.
