RESUMO
Ocular hypertension(OH)can cause a variety of ocular structural and functional damage, among which the effect on ocular refraction has long been recognized in the clinic. The effect of OH on ocular refraction is related to the transparency and shape of refractive media, as well as the changes of the axial length. Due to the different speed and degree of intraocular pressure(IOP)elevation, the changes of refraction are reversible or irreversible. Irreversible changes in refraction are often accompanied by visual transmission impairment, and have a certain reference value for the evaluation of the latter condition. IOP changes lead to changes in the axial length, which are related to scleral remodeling and choroidal perfusion changes, and have a certain impact on the development of myopia and refractive error after cataract surgery. In this paper, the research progress of the changes of refractive media and axial length caused by OH, as well as the characteristics of the effects on ocular refraction are summarized, hoping to deepen the understanding of the effect of OH on ocular refraction, and provide reference for preventing irreversible ocular refractive changes, guiding the assessment of visual transmission damage and preventing or controlling the development of axial myopia.
