To evaluate the influence of the visual acuity after congenital surgery on the retinal and visual cortex structure.
According to the visual acuity after congenital cataract surgery, 30 patients are divided into 3 groups.SD-OCT and MRI were used to measure the parameters of the retina and the visual cortex, to compare the differences between different groups, and to analyze the relationship between the structure of the retina and the visual cortex and visual acuity.
