Investigation of choroidal vascular alterations in eyes with myopia using ultrawidefield optical coherence tomography angiography.

ABSTRACT:

Background/aims

The study aims to evaluate choroidal vascular changes in younger patients with myopia using ultrawidefield swept-source optical coherence tomography angiography (SS-OCTA).

Methods

Overall, 724 eyes of 362 participants (177 males, 185 females, age: 32.43±6.20 years) underwent SS-OCTA imaging (24×20 mm). The eyes were divided into normal, low myopia (LM), moderate myopia (MM), high myopia and superhigh myopia groups according to the spherical equivalent refraction (SER). Changes in choroidal vascular thickness (ChVT) and density (ChVD) in nine grids of the fundus were analysed using the latest version of the built-in analysis software.

Results

Axial length (AL) showed a negative correlation with SER (r=0.822, p=0.000); ChVT and ChVD showed a negat
