Does anemia affect your vision?

According to the Northern Illinois Eye Clinic, anemia can affect the eyes in other ways, too.

Sometimes bleeding in the eyes might not be obvious, but an eye doctor can diagnose anemia during a dilated exam.

Can chronic diseases cause anemia?

Some conditions can cause anemia by over one mechanism (two or even all the three mechanisms). Anemia of chronic disease is a common form of anemia seen in hospitalized patients caused by long-standing diseases, infections, inflammations, and malignancies. These chronic conditions cause increased production of hepcidin[5] by the liver.

How many people are affected by anemia?

Did you know that more than two billion people worldwide are affected by anemia? According to the Cleveland Clinic, not everyone who has it may even realize it. This common condition prevents oxygen from being carried to your body's organs and tissues, often resulting in symptoms such as fatigue, headaches, pale and dry skin, and a fast heartbeat. While there are different types of anemia, the most common is caused by an iron deficiency. It results in a lack of red blood cells, which are essential to delivering oxygen to your lungs and other organs.

What does it mean when your eye is pale?

Paleness is another symptom of anemia, and that includes your eyes.

When a person has a low blood count, they can experience bleeding in their eyes, which can lead to vision loss — both temporary and permanent. Sometimes bleeding in the eyes might not be obvious, but an eye doctor can diagnose anemia during a dilated exam.

What does it mean when you are anemic?

This means when a patient is anemic, they aren’t getting enough oxygen to tissues throughout their body. The treatment for anemia depends on the cause – and there are several – but the causes can be thought of as three groups: blood loss, decreased RBC production and destruction of RBCs.

What causes anemia in the second group?

The most common causes of the second group are iron, B12 and/or folate deficiencies, and this is because those minerals and vitamins are needed to make RBCs. You can also get this type of anemia from bone marrow or stem cell problems. The final type of anemia (when RBCs are being destroyed) is called hemolytic anemia and is rarer than the first two. It’s caused by conditions such as sickle-cell anemia and advanced liver or kidney disease.

Is anemic retinopathy a hypoxic disease?

The hypoxic pathophysiology of anemic retinopathy is similar to – but subtly different from – (but nevertheless intertwined with) ischemia. Ischemia is the interruption of blood flow to tissue, and hypoxia is the decrease of oxygen saturation within tissue. So hypoxic retina could likely be getting a full blood supply, but that blood is deficient in oxygen. Diabetic retinopathy is more caused by ischemic damage, and anemic retinopathy is an example of hypoxic damage ; but they can have similar findings and are often confused for one another. Hypoxia affects the superficial retinal nerve fiber layer more than the deeper retinal vasculature, causing CWSs and FSHs or occasionally sub-hyaloid hemorrhages. So when you see a retinopathy consisting mostly of superficial CWSs and FSHs, think about hypoxia and work the patient up for anemia.

Is anemic retinopathy similar to ischemia?

The hypoxic pathophysiology of anemic retinopathy is similar to – but subtly different from – (but nevertheless intertwined with) ischemia. Ischemia is the interruption of blood flow to tissue, and hypoxia is the decrease of oxygen saturation within tissue.

Is hypoxic retina a blood supply?

So hypoxic retina could likely be getting a full blood supply, but that blood is deficient in oxygen. Diabetic retinopathy is more caused by ischemic damage, and anemic retinopathy is an example of hypoxic damage; but they can have similar findings and are often confused for one another.

Can anemia cause retinopathy?

But keep in mind that true anemic retinopathy is typically found when hemoglobin values are quite low, not your typical mild anemia found in an elderly vasculopath. The range for normal hemoglobin concentration (for men) is 13.5 g to 17.5 g/dL; the concern for anemic retinopathy increases when that value falls below 6 g/dL.

What are the symptoms of anemia?

Commonly, there would be paleness of the skin and mucus membranes in these cases, as well as feeling profoundly tired and fatigue, especially with exercise. Your symptoms could also be caused simply by something known as vasovagal syncope, which is less of a serious problem, often brought out in times of stress, temperature extremes, illnesses like colds or flus, and dehydration. Your doctor will perform a complete physical examination, which might include an electrocardiogram to look at your heart and basic blood work. Based on what the lab work shows and what they find on the physical examination, they will be able to help you figure out what the next steps might be. Make an appointment today!

What does ferritin mean in blood test?

What is the term for the condition where iron is stored in the eye?

Oftentimes the storage protein for iron, ferritin, can reach the eye instead of the mineral itself. The result is hereditary hyperferritinemia cataract syndrome (HHCS), an inherited condition of early-onset cataracts which could be dangerously confused with hemochromatosis (iron overload) unless a person is diagnosed using the full iron panel: ...

How can the body's storage sites for iron be full without iron overflowing into other organs?

But how can the body’s storage sites for iron be full without iron overflowing into other organs? The answer is that a genetic mutation has turned off the body’s ability to make ferritin in response to changing iron levels. This means that ferritin is constantly being made no matter whether iron levels are high or low. In HHCS, components of ferritin accumulate in the eye lens and crystalize – disrupting the light transmission which enables a person to see.

What is the only treatment for HHCS?

Right now, the only known treatment for HHCS is cataract surgery.

What causes vision loss in older people?

Age-related macular degeneration (AMD) is regarded as the leading cause of vision loss for people over the age of 50. The macula, a small portion of the retina which is responsible for sharp and detailed vision, deteriorates over time when the retinal pigment epithelium (RPE) surrounding the macula oxidizes – triggering an inflammatory response.

What is iron chelation therapy?

Iron chelation therapy is the removal of excess iron from the body with special drugs. “Deferiprone can protect the retinas of mice by entering the retina and removing iron from it,” said Dunaief, whose lab is currently testing additional drugs to prevent iron accumulation in the eye.

What happens if you don't have enough iron?

It’s not clear why, but a study in the journal Medical Hypotheses suggests that it may give a boost in mental sharpness the same way a cup of coffee does. Some people may even have cravings for paper and clay too. 8.
