Transcorneal Electrical Stimulation (TES) for the Treatment of Amblyopia

Status Recruiting

Clinical Trial Summary

This is a prospective, randomized, parallel group sham-controlled blinded clinical trial to assess the feasibility and efficacy of transcorneal electrical stimulation (TES) in the improvement of visual function outcomes in adults with amblyopia. The trial will assess the treatment effect of TES to Sham TES in the amblyopic eye of affected patients.

Clinical Trial Description

Amblyopia is defined as a decrease in visual acuity in one eye, despite the correction of any refractive error with glasses and in the absence of any ophthalmoscopically visible lesion of the retina, especially of the macular region. Amblyopia is associated with histologic and electrophysiologic abnormalities in the visual pathways.

Transcorneal electrical stimulation (TES), through neural stimulation, works by non-invasively stimulating the retina via passage of electrical current directly to the retina, bypassing the usual light activation pathway, resulting in the activation of the same areas of the brain as would be activated with a light stimulus alone. Electrical stimulation with TES has shown potential in recent reports as an efficacious treatment modality to improve visual function.

The success of electrical stimulation in neurodegenerative disorders provides a reasonable rationale and significant precedent to investigate its potential for use in disorders of the visual processing system, which functions via an integration of biochemical and electrical interactions transmitted from the retina. ;
