Elevated Nasal-Temporal Asymmetry of the Choroidal Vascular Index in Pathologically Myopic Eyes.

ABSTRACT:

Purpose

This study aimed to investigate regional variations in choroidal parameters and to assess whether intraocular symmetry can aid in identifying pathological myopia.

Methods

Optical coherence tomography (OCT) images were analyzed from 53 eyes with non-high myopia (NHM), 30 eyes with simple high myopia (HM), and 29 eyes with pathological myopia (PM). Choroidal thickness (CT), luminal area (LA), stromal area (SA), and choroidal vascularity index (CVI) were measured within a 6 mm diameter macular region centered on the fovea. Intraocular symmetry of choroidal parameters was quantified by calculating absolute differences between the nasal and temporal, as well as the superior and inferior, regions. These measurements were combined with existing clinical data to help disting
