Abstract

PURPOSE: To evaluate the effect of one TrueTear session on change in tear volume and symptoms of dryness and ocular pain.

METHODS: Retrospective interventional case series of patients seen in a dry eye clinic. Seventy-five individuals underwent an ocular surface examination and one session of neurostimulation. Outcome measures included objective change in tear volume measured via phenol red test, and subjective change in sensations of dryness and ocular pain measured on a 0-10 Numerical Rating Scale.

RESULTS: The mean age of the 75 individuals was 59±13 years, and the majority were male (73%). Intranasal neurostimulation increased tear volume (mean 13.40±8.00 mm, p

CONCLUSION: Intranasal neurostimulation increased tear volume and reduced intensities of dryness and ocular pain, independently of one another.
