Purpose: To explore the association of choroidal vascularity and choriocapillaris blood perfusion with myopic severity in anisomyopes. Methods: Refractive error, axial length (AL), other biometric parameters were measured 34 anisomyopic young adults. Macular thickness (ChT) vascularity, including total area (TCA), luminal (LA), stromal (SA), index (CVI), determined from swept-source optical coherence tomography (SS-OCT) vertical horizontal B-scans. The percentage flow voids (FV%) was obtained en face SS-OCT-angiography. Results: spherical equivalent refraction (SER) –3.35 ± 1.25 diopters more eyes –1.25 1.17 less (P < 0.001). interocular difference SER highly correlated that AL macular ChT, TCA, LA, SA smaller than both scans (all P Importantly, CVIs FV% greater 0.05). In scans, SER, AL, ChT ChTs Conclusions: Choroidal lower These changes myopia thinning, indicating is disturbed human myopia.
