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 < 0.05. Results: There was no difference in baseline characteristics between LLRLT eyes and non-LLRLT eyes. The RFPD in LLRLT eyes significantly increased 5 minutes after LLRLT and the increment was 1.70±0.83 % (p = 0.0389). The RFPD significantly decreased from 5 minutes to 1 hour after LLRLT with a mean of -2.62±0.86 % decrement (p = 0.0031). The RFPD levels returned to baseline at 1 hour after LLRLT (p = 0.8646). However, compared with insignificant RFPD changes in non-LLRLT eyes, there was no significant difference in RFPD changes at any sampling point. No significant changes in RFT, CFBF, and CFT were found in LLRLT eyes at each sampling point. Conclusion: Although LLRLT has no effect on the choroid, it may cause a short-term transient increase in RFPD. It will provide theoretical support for the role of LLRLT in myopia control.

Markers of the functional state of the hepatobiliary system — enzymatic activities of alanine aminotransferase (ALT), aspartate aminotransferase (AST), γ-glutamyltransferase (GGT), levels of total and direct bilirubin, the value of thymol probe in the plasma of the diaphragm waves and the introduction of ω-3 PUFA were investigated. It has been found that the action of laser irradiation in blood plasma increases the enzymatic activities of aminotransferases and GGT, along with an increase in the level of total and direct bilirubin and thymol index. The corrective effect on the liver functional state is shown by ω-3 polyunsaturated fatty acids (PUFA). It has been established that the protective properties of ω-3 PUFAs depend on the scheme of their introduction. The highest hepatoprotective effect of ω-3 PUFAs is manifested under the conditions of their previous introduction to the action of laser irradiation, as evidenced by a decrease in hyperenzymemia ALT, AST, GGT, a decrease in total and direct bilirubin and thymol in plasma. The introduction of ω-3 PUFA after the end of the laser diode does not change the markers of the functional state of the liver in blood plasma compared with irradiated animals that were not injected with the studied lipophilic nutrients.
