Photobiomodulation therapy for congenital color vision deficiency: results of a preliminary randomized clinical trial.

ABSTRACT:

Purpose

This study presents a novel randomized controlled trial investigating photobiomodulation (PBM) therapy as an intervention method for color vision deficiency (CVD).

Methods

A total of 74 participants with CVD were assigned to either the PBM group or the control group. In the PBM group, participants wore virtual reality (VR) goggles twice daily, with a 12-h interval, over a four-week period. The VR video consisted of alternating red and green images, each presented for 5 s, totaling 6 min and 20 s. No treatment was administered to the control group. Color vision improvement was assessed using Yu's, Ishihara's pseudoachromatic plates, Color Blindness Check (CBC), and FM-100 Hue total error score (TES).

Results

After 4 weeks, in terms of Yu's and Ishihara's Plates
