Abstract:
AIM: To compare the differences in choroidal structure between hyperopic amblyopia and normal children of the same age by the enhanced depth imaging optical coherence tomography(EDI-OCT)technique.METHODS: There were 35 cases in 50 eyes of children with hyperopic amblyopia visiting our hospital in January 2021 to December 2021 selected in the amblyopic group, and 30 cases in 51 eyes of healthy children who matched general data in the same period were selected in the control group. EDI-OCT examination was performed to measure the choroidal thickness(CT). After image processing, the total choroidal area(TCA), luminal area(LA), stromal area(SA)and choroidal vascularity index(CVI)were obtained.RESULTS: TCA(except inferior quadrant), SA(except inferior quadrant of the outer ring), LA and CT(except inferior and temporal quadrant )in the amblyopic group of each area were significantly larger than that in the control group(P<0.05), and there was no significant difference in CVI between the two groups except the temporal quadrant of the outer ring(P>0.05). There was no significant difference in CT for all degrees of hyperopic amblyopia, with the exception of the nasal quadrant(P>0.05).CONCLUSION: Hyperopic amblyopia is accompanied with abnormal choroidal structure. As the degree of hyperopia increases, TCA, LA and SA exhibit increasing trends. The changes in choroidal structure are presumed to be related to hyperopic amblyopia.
