Low Blood Pressure and Eyesight

High Blood Pressure and Eyes Feel Weird

Table of Contents

Low blood pressure may seem harmless at first, but if left untreated it can quickly lead to serious consequences if left untreated – including dizziness and fainting due to temporary lack of blood supply to the brain, and blurred vision caused by decreased circulation to eyes.

Blood pressure tests measure the force of your blood against the walls of your arteries. If it falls below 90 systolic/60 diastolic, that indicates low blood pressure.

Causes

Blood pressure refers to the force of your blood pushing against the walls of your arteries. It reaches its maximum when your heart contracts and pumps blood, and drops when at rest between beats. Your reading can be represented with two numbers: systolic pressure over diastolic pressure (for example 120/80). Blood pressure typically falls when relaxed or not drinking alcohol or stressed out whereas it typically increases when exercising or stressed. Most people don’t notice they have low blood pressure continuously but sudden drops, worsening, dizziness or fainting could present problems which require medical intervention if left unchecked – especially if dizzyness or fainting occurs unexpectedly or causes dizziness or fainting.

Your eye doctor can evaluate the arteries and blood vessels in your eyes to detect hypertension or other conditions that could impair your vision. High blood pressure can damage small blood vessels in the retina (the layer lining the back of your eye) restricting blood flow to this layer and potentially leading to glaucoma.

High blood pressure can negatively impact the arteries that supply the brain with blood. Clogged arteries can inhibit circulation to your mind and hinder vision as a result.

High blood pressure often manifests itself through multiple micro clots in the brain that may result in stroke or mini-strokes, and which may even compromise vision causing blurriness or even blindness. These micro clots may even impact eyesight negatively leading to blurred or even blind vision in some individuals.

Intraocular pressure (IOP) can also be a risk factor for glaucoma. A healthy intraocular pressure ranges between 10-21mm Hg. If your intraocular pressure falls outside this range, this indicates ocular hypertension which needs treatment to protect vision loss from glaucoma.

Other risk factors of ocular hypertension can include age, diabetes or its history and medications that cause side effects that contribute to elevated eye pressure. If any of these are present in your life, an eye doctor will recommend regular exams to detect possible cases of ocular hypertension.

Shock occurs when blood pressure quickly and unexpectedly drops below safe levels and doesn’t rebound quickly to restore itself, such as due to trauma, infection (such as septic shock) medications or medical conditions like cardiac arrest. This condition should never be taken lightly!

Symptoms

Low blood pressure symptoms may include dizziness or lightheadedness upon suddenly standing up, caused by insufficient blood flow to the brain for a short period. Other indicators of low blood pressure can include blurred vision due to oxygen deprivation reaching eyes through blood. In severe cases, low blood pressure can even result in shock; an extreme situation in which organs no longer receive enough blood flow to function effectively.

As part of diagnosing low blood pressure, doctors typically use a device known as a sphygmomanometer to take readings on an arm cuff that has been placed around and inflated until blood flow restriction creates an audible “pounding sound” audible to physicians or nurses using stethoscopes on elbows. This measurement provides two numbers; first being the systolic pressure responsible for filling up arteries when the heart beats, followed by diastolic pressure which measures pressure inside arteries between beats.

Other diagnostic tools may also be employed to ascertain the underlying causes of low blood pressure, including blood tests and an electrocardiogram (ECG), which measures electrical activity within the heart. A cardiologist may suggest an echocardiogram instead, which produces images that help doctors assess cardiac chambers and blood vessels in order to diagnose abnormalities such as abnormal valves.

A dilated eye exam may also be performed to inspect the structures of the retina and eye for signs of high cholesterol or other health conditions. For example, in someone suffering from hypertensive retinopathy an ophthalmologist will be able to observe narrowing of blood vessels within the retina, hemorrhages as well as areas that seem brighter due to lower blood flow to their eyes.

Though occasional episodes of low blood pressure can be harmless, long-term low blood pressure should be addressed as it poses health concerns and should be treated. When lifestyle modifications and other therapies fail to control normal levels, medications may be prescribed by medical practitioners as a solution. To determine an individual’s ideal medication combination, doctors usually consider age, overall health status, medical history and individual preference when prescribing appropriate doses of medication.

Diagnosis

Many people with low blood pressure experience no symptoms and don’t require treatment; long-term (chronic) low blood pressure doesn’t need either. If your blood pressure drops too far though, heart and organs could not get enough blood to function normally – your doctor can check whether this is happening by taking your pulse and measuring both systolic and diastolic blood pressures.

Eye doctors can detect high blood pressure by observing retinal blood vessel damage. Clogged arteries block or slow down blood flow to the eye, leading to vision loss. Only in the eye can doctors directly observe arteries and veins, providing insight into whether hypertension or atherosclerosis has damaged other blood vessels in the body.

Hypertensive Retinopathy, the condition that results from uncontrolled high blood pressure, is often discovered during routine eye exams. A dilated exam allows an eye doctor to observe narrowing of blood vessels in the retina, hemorrhages or areas with poor blood flow as well as swelling in the optic disc (papilledema), all signs that you need your high blood pressure treated immediately in order to protect both eyes and other parts of your body from potential irreparable damage.

Ocular hypertension, another side effect of chronically high blood pressure, increases your risk for glaucoma. A doctor can use a tonometer to measure your intraocular pressure during a dilated eye exam and also look for family history of ocular hypertension or glaucoma as well as evaluate symptoms; African American individuals and those who are extremely nearsighted have an increased chance for developing it.

If you have ocular hypertension, seeing an eye doctor will help treat it by prescribing medicated eye drops that reduce pressure inside the eye. They may also need to understand your medical history including any medications taken and any over-the-counter vitamins and supplements taken; this can help your physician avoid potential drug interactions that might be contributing to or causing your hypertension.

Treatment

Hypotension (low blood pressure) can have serious repercussions for your eye health, particularly when combined with other medical conditions like diabetes or heart disease. Routinely monitoring your blood pressure is critical if symptoms such as dizziness or fainting arise, so that changes can be linked to modifications and you can take timely steps.

As a rule of thumb, blood pressure readings between 90 systolic mm Hg and 60 diastolic mm Hg are considered low. However, doctors always interpret this number within the context of individual’s baseline measurements, past measurements and current health status.

At home and with different people, blood pressure can fluctuate considerably throughout the day and from person to person. Therefore, it’s wise to measure your BP at least once every day at home and carry around a small wrist monitor in order to keep track of it. Do keep in mind that various factors could alter measurements, including arm positioning, white-coat syndrome, bladder urgency or recent smoking; too large of cuff sizes can also lead to inaccurate readings; ensure you use one suitable for your body size when taking measurements.

Low blood pressure usually isn’t a cause for alarm unless symptoms like fainting or loss of consciousness arise, since significant drops usually indicate that heart and brain aren’t getting enough blood, leading to symptoms like fainting or losing consciousness. However, sudden loss of blood due to severe injuries, infection or shock-inducing medications like antidepressants, diuretics, alpha and beta blockers or Parkinson’s drugs can drastically decrease your BP levels and be life-threatening.

If you have been diagnosed with low blood pressure, treatment typically entails treating its root cause. In Addison’s disease for instance, hormone replacement therapy might be needed, while diet changes, increasing fluid intake and compression stockings could all be useful strategies. In extreme cases medications like fludrocortisone may help by increasing how much sodium your kidney retains while also increasing blood volume.
