Hypertension has profound effects on various parts of the eye. Traditionally, elevated blood pressure brings about a series of retinal microvascular changes called hypertensive retinopathy, comprising of generalized and focal retinal arteriolar narrowing, arteriovenous scratching, retinal hemorrhages, microaneurysms and, in severe cases, optic plate and macular edema. Studies have given that gentle hypertensive retinopathy indications are normal and seen in about 10% of the general grown-up non-diabetic population.
Hypertensive retinopathy signs are related to different pointers of end-organ harm (for instance, left ventricular hypertrophy, renal impairment) and perhaps a risk marker of future clinical events, for example, stroke, congestive heart failure, and cardiovascular mortality. Furthermore, hypertension is one of the major risk factors for the development and progression of diabetic retinopathy, and control of pulse has been appeared in huge clinical trials to keep visual loss from diabetic retinopathy.
In addition, several retinal diseases, for example, retinal vascular impediment (artery and vein occlusion), retinal arteriolar emboli, microaneurysm, ischemic optic neuropathy, and age-related macular degeneration may also be related to hypertension; however, there is as yet no evidence that treatment of hypertension prevents vision loss from these conditions. In the management of patients with hypertension, physicians should be aware of the full spectrum of the relationship between blood pressure and the eye.
Hypertension is related to significant, regularly asymptomatic, multisystem impacts. The eye isn’t saved the impacts of elevated blood pressure. In any case, the eye is distinctive in that it permits the direct sequel of elevated blood pressure to be visualized early, particularly changes in the retinal microvasculature. The most well-known effect of hypertension on the eye is therefore the condition called hypertensive retinopathy, wherein the retinal circulation undergoes a series of changes in response to high blood pressure.
Hypertensive retinopathy has long been regarded as a risk marker for systemic morbidity and mortality. However, besides hypertensive retinopathy, elevated blood pressure has a key role in the pathogenesis of diabetic retinopathy, a major cause for vision loss in working adults. In fact, control of blood pressure has been shown in large clinical trials to prevent the progression of diabetic retinopathy and prevent blindness, an effect that is almost equivalent to control of hyperglycemia.

Finally, several retinal diseases, for example, retinal vascular occlusion (artery and vein occlusion), retinal arteriolar emboli, microaneurysm, ischemic optic neuropathy, and age-related macular degeneration may also be related to hypertension, yet these relationships are not as well known to physicians. This review will summarize the board ocular effects of hypertension, concentrating on literature published in the most recent decade.
We know about the many serious consequences of living with high blood pressure or hypertension. Delayed, untreated hypertension can negatively affect your heart and your kidneys, but how can hypertension affect your eyesight?
High blood pressure can lead to a condition known as hypertensive retinopathy and the harm can be very serious if not addressed.
The retina is a layer of tissue situated at the rear of the eye and contains cells that are sensitive to light. These cells trigger nerve impulses that pass via the optic nerve to the brain, where a visual image is formed. When your blood pressure is too high, the walls of the retina may thicken, which restricts blood flow to the retina and limits its function, resulting in potentially permanent vision problems, including blindness.
A person with hypertensive retinopathy wouldn’t commonly show any symptoms until the condition has progressed. Potential signs may include:
- Decreased vision
- Eye swelling
- Bursting of a blood vessel
- Double vision accompanied by headaches
In most cases, an eye specialist can diagnose hypertensive retinopathy during an examination utilizing an instrument called an ophthalmoscope to examine the retina. Your doctor will look for signs of narrowing of blood vessels, spots on the retina, swelling, or bleeding in the back of the eye.
Effective treatment for hypertensive retinopathy includes controlling your blood pressure. This should be possible through medication and lifestyle changes. Most importantly, doctors recommend maintaining ideal body weight, eating, and a healthy diet and exercising regularly as methods to lower your blood pressure.
