Enhanced depth imaging optical coherence tomography: a study of the choroid in high axial myopia

ABSTRACT

Background: High myopia is one of the main causes of visual impairment worldwide. About 1% of the population has high myopia. There is significant evidence from research with animal models and humans that the development of refractive errors is associated with changes in the structural characteristics of the choroid. Studies from a range of different animal species, including chicks, macaque monkeys, indicate that alterations in choroidal thickness [CT] can precede and accompany the development of myopic refractive errors
