Choroidal circulation disturbance is an initial factor in outer retinal degeneration in rats under simulated weightlessness
Objective: Microgravity contributes to ocular injury yet the underlying mechanism remains unclear.This study aims to elucidate the mechanism behind choroidal circulation disorder and outer retinal degeneration in rats with simulated weightlessness.Methods: Optical coherence tomography angiography (OCTA) was used to evaluate choroidal circulation an
