How are High Blood Pressure and Eye Disease interrelated?

This is a common known fact that if you have high blood pressure, you may be more prone to heart, kidney problems or strokes but it has also been found that high blood pressure often affects the eye vision and can lead to eye disease. Hypertension affects the eyesight by damaging the blood vessels in the retina which is usually responsible for image formation in the eye. It is also known as hypertensive retinopathy. The damage could be serious and permanent if hypertension remains untreated.

Know more about Hypertensive Retinopathy:

When your tiny blood vessels that are responsible for supplying the blood to light sensitive areas in the back of eye are damaged because of your high blood pressure, then the damage is usually called as retinopathy. If hypertension is not treated, then the problem can turn to be really serious. Higher the blood pressure, higher will be the severity of retinopathy, therefore it must be treated as soon as possible.

What are the symptoms?

There are not much symptoms related to eye problem as this is directly related to hypertension. Only an Eye specialist could diagnose hypertensive retinopathy, but still there are a few symptoms that may arise like

                                                                      1.  Headache

                                                                      2.  Blurred Vision

Diagnosis of Hypertensive Retinopathy:

Ophthalmoscope is a device which is generally used by eye specialist to diagnose whether the patient has hypertensive retinopathy or not. This equipment projects light to examine the back of eye and see the signs of damage.

If you don’t want any complications in the eye and want to get rid of all the threats, it is most important to keep your blood pressure under control. Regularly visit your doctor and get the proper prescription. Keep track of your blood pressure. Do not change your treatment or stop the medications without consulting with the doctor.

There are various ways in which you can treat hypertensive retinopathy:
