Moreover, while the nonperfusion group showed a trend toward higher proportions of severe stenosis and occlusion, the overall carotid stenosis distributions between the two chronic CRAO subtypes were not statistically different (delayed perfusion vs. nonperfusion, p = 0.392), suggesting that both persistent ischemia groups share comparable underlying advanced vascular disease burden.
