Retinopathy caused by increased blood pressure and retinal haemorrhage

2021-03-16 12:00 AM

Prolonged hypertension leads to endothelial thickening and ischemia. Degenerates blood vessels of the retina to the point of oozing plasma and bleeding on the retina.

Retinopathy caused by increased blood pressure

Are associated with the pathological changes seen in retinal blood vessels due to (or as an indicator of) increased blood pressure. Several signs are also used as indicators of the severity of high blood pressure.

There has been a renewed interest in retinopathy due to hypertension as a marker, prognosis and risk factor for the disease.

Retinopathy caused by mild and moderate hypertension increases the risk of high blood pressure 1-2 times.

Retinopathy caused by mild and moderate hypertension increases the risk of stroke 1-8 times.

Retinopathy caused by mild hypertension increases the risk of coronary artery disease by 2-3 times.

Retinopathy caused by moderate hypertension increases the risk of cognitive decline.

Retinal haemorrhage

Description

Bleeding in the retina or overflowing to the retina. It can be in the form of 'spots and marks' or 'streaks'.

Figure. Spot and stains haemorrhages and microaneurysms

Reason

Frequent

Hypertension.

Diabetes.

Injury.

Less common

Clogged retinal veins.

Retinal artery occlusion.

Mechanism

Prolonged hypertension leads to endothelial thickening and ischemia. Degenerates blood vessels of the retina to the point of oozing plasma and bleeding on the retina.
