High blood pressure causes eyeground bleeding.

High blood pressure can cause ocular fundus bleeding, which may be related to vasospasm, increased aqueous outflow resistance, eye diseases and other factors.

1, vasospasm

High blood pressure will accelerate blood flow, which will lead to increased pressure on the blood vessel wall, causing vasospasm, causing hardening of the blood vessel wall, resulting in rupture, resulting in ocular fundus bleeding.

2, aqueous outflow resistance increased for a

long time High blood pressure will also affect the trabecular meshwork part of the aqueous outflow resistance increased, resulting in increased intraocular pressure, causing capillary rupture, resulting in ocular fundus bleeding.

3, Eye diseases

themselves Patients with conjunctivitis, conjunctivitis, glaucoma and other diseases, the eye blood vessels are relatively fragile, affected by increased blood pressure, but also prone to rupture, causing ocular fundus bleeding.
