AIM:To observe the different effects of three intervention approaches on related biometric parameters in children diagnosed with latent myopia, and to investigate different control effects on children with latent myopia.METHODS:Prospective cohort concurrent controls trials. A total of 60 cases(120 eyes)of children who were initially diagnosed as latent myopia and untreated previously at ophthalmology clinic of the Affiliated Hospital of Chengde Medical University from December 2021 to May 2022 were recruited. They were randomly divided into three groups, with 20 cases(40 eyes)in group A treated with 0.01% Atropine eye drops, 20 cases(40 eyes)in group B treated with vision training with a flip chart, and 20 cases(40 eyes)in group C treated with esculin and digitalis glycosides eye drops. They were followed-up for 12 mo, and the spherical equivalent(SE), axial length(AL), corneal curvature(CC), accommodative facility(AF), and macular retinal thickness of the three groups of children were compared at 6 and 12 mo post-intervention.RESULTS:Significant statistical differences were found in AL, SE and AF of the three groups of children at 6 and 12 mo(all P0.05). The retinal thickness of the temporal, nasal, inferior and macular fovea of the outer ring at 6 and 12 mo after intervention in the three groups was significantly different from that at the initial diagnosis(all P0.05).CONCLUSION:When it comes to preventing and controlling myopia, 0.01% Atropine is more effective than flip chart training and esculin and digitalis glycosides eye drops. Therefore, the administration of 0.01% atropine and the implementation of flip chart training can effectively slow down the advancement of latent myopia. |
