Summary

This pilot study will test the preliminary efficacy and feasibility of an intervention protocol for one method of electric current stimulation, repetitive transorbital alternating current stimulation (rtACS), to treat visual impairment in people with glaucoma. We will evaluate a study protocol to use in future clinical trials to test the effectiveness of rtACS to ameliorate the progressive effects of vision loss both structurally and functionally in the eye, the visual pathway, and in regard to people's independence (i.e., functional ability). In this prospective, randomized controlled, double-masked pilot study, we will: 1) determine an effect of rtACS on ophthalmic structure and function (from retina to visual brain), 2) assess the methodology of procedures for assessment of people's functional ability and quality of life (QoL) to determine an effect of rtACS, and 3) assess the feasibility and implementation of the pilot study protocol for a larger multi-site, randomized controlled trial.

Conditions

Interventions

DEVICE

rtACS Stimulation

Electric current stimulation; rtACS is a non-invasive application of electric current to stimulate the retina to induce synaptic efficacy, in particular those cells that have some measure of dysfunction but are not dead, and oscillations of nearby neuronal ensembles.

DEVICE

Sham Intervention

A computer-controlled sham stimulation function for masking interventionist to study group. The device will be used to deliver a weak electric current stimulation protocol to participants via electrodes placed transorbitally, with one reference electrode positioned elsewhere.
