Retina Clinical Trial
Official title:
Effect of Different Wavelengths of Repeated Low-Level Light Therapy on Choroidal and Retinal Blood Flow Among Adults
The purpose of this clinical trial is to evaluate the effect of different intensity of repeated low-level red-light (RLRL) therapy on the choroidal and retinal blood flow among adults.
Repeated low-level red-light (RLRL) therapy is an emerging innovative and non-invasive treatment for a variety of eye diseases. Notably, RLRL was found to be effective in thickening choroidal thickness in a 1-year randomized controlled trial, indicating its potential in modulating blood flow in the fundus. However, it remains unclear how long it takes for the RLRL to make a difference in fundus blood flow and whether there is a dose-response. The purpose of this study is to evaluate the different wavelengths of of repeated low level light therapy on the choroidal and retinal blood flow among adults. This study will be conducted with a randomized cross-over design with a total follow-up of 3 months. The repeated low level light therapy will be carried out in the study site under supervision according to a standard protocol. Detailed ophthalmic examinations, including visual acuity, intraocular pressure, optical coherence tomography/angiography, optical coherence tomography angiography, cycloplegic spherical equivalent refraction, slit lamp, and biological parameters will be evaluated at enrollment and during follow-ups. ;
