Study on the Changes of Macular Retinal Thickness in Myopia

摘要

With the increasing use of eyes at close range, myopia has become a public health problem in many areas. Fundus changes caused by high myopia have become one of the main causes of vision loss. In order to have a deeper understanding of myopia, we need to clarify the characteristics of myopia. In this paper, the retinal tomographic images obtained by optical coherence tomography (OCT) were used to analyze the changes of retinal thickness and retinal boundary morphology of myopia with the myopic diopter. The results showed that the retinal thickness and diopter have the highest correlation in the 2-2.5 mm region of the macula from the nasal side. The retinal thickness in this region was reduced by approximately 3.189 µm per unit of myopic diopter degrees. The subretinal boundary can be modeled by a quadratic function, and the quadratic coefficient decreases with increasing diopter.
