- Severe hypertension in retinal precapillary arterioles causes endothelial disruption, leakage of plasma into arteriolar wall, and fibrinous necrosis
- Necrotic vessels can then bleed into nerve fiber layers causing the flame shaped hemorrhages
- Fundus pictures of malignant hypertensive retinopathy with bilateral disc edema, peripapillary splinter hemorrhages, cotton wool spots, vascular tortuosity, macular star, venous engorgement
