Symptoms may include: Double vision, dim vision, or vision loss Headaches Sudden symptoms are a medical emergency. It often means that the blood pressure is very high. Exams and Tests. The degree of damage to the retina retinopathy is graded on a scale of 1 to 4: Grade 1: Usually you would not have symptoms.

Grades 2 to 3: There are a number of changes in the blood vessels, leaking from blood vessels, and swelling in other parts of the retina. Grade 4: You will have swelling of the optic nerve and of the visual center of the retina macula. This swelling can cause decreased vision. You may need a special test to examine the blood vessels.

Outlook Prognosis. This layer transforms light into nerve signals that are then sent to the brain for interpretation. This may cause your blood vessels to become narrow, which then restricts blood from reaching the retina. In some cases, the retina becomes swollen.

This condition is called hypertensive retinopathy HR. Possible signs and symptoms include:. Get medical help immediately if your blood pressure is high and you suddenly have changes in your vision.

Prolonged high blood pressure, or hypertension, is the main cause of HR. High blood pressure is a chronic problem in which the force of the blood against your arteries is too high.

The force is a result of the blood pumping out of the heart and into the arteries, as well as the force created as the heart rests between heartbeats.

When the blood moves through the body at a higher pressure, the tissue that makes up the arteries will begin to stretch and eventually become damaged. This leads to many problems over time. HR generally occurs after your blood pressure has been consistently high over a prolonged period.

Your blood pressure levels can be affected by:. In the United States, high blood pressure is fairly common. According to the Food and Drug Administration FDA , the condition affects 1 in 3 adults in the United States.

After the first round of pictures, your doctor will inject a dye called fluorescein into a vein. The extent and severity of the retinopathy is generally represented on a scale of 1 to 4. The scale is called the Keith-Wagener-Barker Classification System.

The four grades increase in severity:. On the lower end of the scale, you may not have any symptoms. At grade 4, however, your optic nerve may begin to swell and cause more serious vision problems.

High-grade retinopathy tends to indicate serious blood pressure concerns. People with HR are at risk of developing complications related to the retina. These include the following:. People with HR are also at an increased risk of having a stroke or heart attack. One study of 2, people between the ages of 50 and 73 found that those with HR were more likely to have a stroke than people without the condition.

This was true even in people with blood pressure controlled by treatment. A study of 5, people between the ages of 25 and 74 showed both an increased risk of stroke or cardiovascular disease in those with HR. Effective treatment for HR involves controlling and lowering high blood pressure with a combination of medications and lifestyle changes.

The best course of action to take in order to avoid Hypertensive Retinopathy is to pair your healthy lifestyle with regular visits to your eye doctor. Stay ahead of the game on any issues, and your chances of developing any dangerous conditions will be limited.
