Abstract:
AIM: To explore the efficacy and safety of repeated low-energy red light irradiation combined with visual training for the treatment of adolescent myopia based on vision and tear film function.METHODS: A total of 104 adolescent myopic patients(208 eyes)from the Second Hospital of Hebei Medical University from January 2022 to July 2023 were selected and randomly divided into two groups by random number table method, with 52 cases(104 eyes)in the control group and 52 cases(104 eyes)in the study group. Both groups were treated with orthokeratology lenses, while the control group received visual training and the study group received repeated low-energy red light treatment on top of visual training. Follow-up for 1 a, the improvement of vision, changes in the choroid, tear film function, adverse events, and visual acuity growth after 1 a were compared between the two groups before and after treatment.RESULTS: The uncorrected visual acuity(LogMAR)and axial length of the study group were lower than those of the control group after 6 mo and 1 a of treatment(all P<0.05). The thickness of the choroid under the center recess and the density of choroidal capillary blood flow were higher in the study group than in the control group at 6 mo and 1 a after treatment(all P<0.05); there was no statistically significant difference in the thickness of tear film lipid layer and tear film break-up time between the two groups at different time points(all P>0.05); and the incidence of adverse events during the treatment period of the two groups was not statistically significant(P>0.05). After treatment for 1 a and removing the orthokeratology lens for 2 wk, there was no significant difference in the uncorrected visual acuity(LogMAR)between the study group and the control group before treatment(P>0.05), and the uncorrected visual acuity of the control group was better than that before treatment(P<0.05).CONCLUSION: Repeated low-energy red light combined with visual training can effectively improve the choroid, control the axial length growth, effectively correct the vision of the cornea, and does not affect the tear film function, with high safety.
