Short-Term Effect of Stimulating the Pterygopalatine Ganglion Via Electroacupuncture on Choroidal Structure in Human Subjects.

ABSTRACT:

Purpose

Choroidal dysfunction is implicated in various ocular pathologies. The parasympathetic pterygopalatine ganglion (PPG) innervates orbital vessels supplying the choroid. While PPG stimulation has been shown to dilate cerebral blood flow, its effects on the choroid, particularly in human subjects, require further elucidation. This study aimed to investigate the short-term influence of PPG stimulation via electroacupuncture on choroidal structure.

Methods

In this crossover study, 22 healthy adults received PPG electrical stimulation and sham stimulation for one session each on two separate days in a randomized order. Measurements including choroidal thickness (ChT), choroidal vascularity index (ChVI), central subfield thickness, axial length, anterior chamber depth, and
