Vascular Changes of the Choroid and Their Correlations With Visual Acuity in Pathological Myopia

Abstract

Choroidal vascular alterations, especially decreased CVI, occurred in patients with pathological myopia. The CVI decreased with axial elongation beyond the flexion point and was correlated with visual impairment, indicating that the CVI might be a reliable imaging biomarker to monitor the progression of pathological myopia.
