Immediate effect in retina and choroid after 650 nm low-level red light therapy in children

Introduction: To investigate the changes in the retina and choroid of children after 650 nm low-level red light therapy (LLRLT). Methods: In this prospective study, 25 subjects in the Shanghai Eye and ENT Hospital of Fudan University were included from August 2021 to September 2021. One eye was randomly selected to receive LLRLT for 3 minutes. Swept-source optical coherence tomography (OCT) and OCT angiography (OCTA) were used to measure retinal fovea perfusion density (RFPD), retinal fovea thickness (RFT), choroidal fovea blood flow (CFBF), and choroidal fovea thickness (CFT) before LLRLT, 5 minutes and 1 hour after LLRLT. Baseline characteristics between LLRLT and non-LLRLT eyes were compared. Changes in the retinal and choroidal parameters were analyzed by ANCOVA models. SAS software was used for data analysis. The difference was considered statistically significant if p
