Studies focusing on the electrophysiology of the retina.
| Year | Title | Authors | Subjects | Element of Study | Primary Endpoint | Type of Study | Outcome |
|---|---|---|---|---|---|---|---|
| 2011 | Impact of blue vs. red light on retinal response of patients with seasonal affective disorder and healthy controls | Gagné et al. [46] | 20 | Cones and rods | ERG | Prospective controlled study | Positive: blue light decreases maximal ERG response |
| 2018 | Effect of Heat-Killed Lactobacillus paracasei KW3110 Ingestion on Ocular Disorders Caused by Visual Display Terminal (VDT) Loads: A Randomized, Double-Blind, Placebo-Controlled Parallel-Group Study | Morita et al. [47] | 62 | Cones and rods | CFF, VAS, CS |
Prospective, randomized, controlled study | Neutral: significant improvement 4 weeks after intake, but not during the 8th week |
| 2021 | Blue Light from Cell Phones Can Cause Chronic Retinal Light Injury: The Evidence from a Clinical Observational Study and a SD Rat Model | Li et al. [48] | 25 | Cones and rods | mfERG | Prospective, randomized, controlled study | Positive: reduced amplitude of parafoveal regions |
ERG = electroretinogram; CFF = critical flicker frequency; VAS = visual analog scale; mfERG = multifocal ERG.
