Changes in each retinal and choroidal vascular layer according to changes in IOP from 15 to 90 mmHg, and the recovery state. Retinal capillary attenuation was found at 30 mmHg of IOP. At 45 mmHg, arterioles and venules were observed, but capillary perfusion significantly diminished. In the recovery state, all the retinal capillary layers seemed to have similar signal intensity to baseline. All scale bars indicate 1000 μm.
