How vision is processed
When a person is suffering from Hypertensive retinopathy they usually do not suffer or show signs from changes in the vision until changes are in the advanced stages (Garg, 2014). Hypertensive retinopathy is caused by high blood pressure which can cause damage to the retina. Abnormalities come from high blood pressure causing blockage in the small arteries, blockage of the retinal blood vessels (sometimes bleeding from the retinal blood vessels) and inflammation in the optic nerve (Retinopathy).
