In what cases should we see a doctor for the treatment of lightheadedness and blurred vision?




If we know and become familiar with the causes of lightheadedness and the factors that cause blurred vision, this knowledge will help us to be able to quickly understand the situation and discuss it with our doctor in cases where we encounter these symptoms. We can also know the possibilities we will face.

This awareness helps us to identify the underlying disease behind these symptoms, namely dizziness, lightheadedness, and blurred vision, before it cripples us and makes us incurable.

In other words, by being aware of these cases and possibilities, we will realize our underlying disease sooner and our worries about the disorder we are suffering from will decrease.


What can be the cause of blurred vision?

We have selected a few common ones. We will name these in the following and we will explain a little about each of them:


  • Poor eyesight

With anatomical changes in the size and shape of the eyeball, or changes that occur in the lens and cornea, a person may no longer be able to focus light on the object in the right place on the screen at the base of the eye. This can cause the images to be incomplete and person can’t look and see objects clearly from far and near distances and these refractive errors are corrected with glasses, lenses and simple surgeries.


  • Eye fatigue

If you are a person who spends a lot of time looking at the pages of a computer, mobile phone, laptop and tablet, or staring at the pages of a book for a long time, you will probably get eye fatigue. When a person focuses on something, he blinks less. In fact, every time you blink, tears spread to the surface of the eye and keep the surface of the eye soft and moist and It is also the surface of the eye that is cleansed by these tears and its fatigue is reduced. To prevent eye strain, you need to remind yourself to blink when working with digital screens, working with computer equipment, and studying.

In the middle of work, be sure to stop work and rest. Close your eyes and look around and away to rest your eyes.


  • diabetes Mellitus

If blood sugar is not well controlled, fluids will enter the lens of the eye and swell it. This can happen when your diabetes mellitus has not yet been diagnosed or treated properly, such as when a person has not started insulin injections.

Also, blood sugar over time affects the retina, which is a membrane at the base of the eye and plays a major role in vision, causing retinal disorders and causing diabetic retinopathy and major problems.

Therefore, it is recommended that the eye be regularly examined in patients with diabetes.

Another important point to know is that a person with type 1 diabetes or a person with type 2 diabetes can have different eye examination programs and protocols, so if one of you and those around you have diabetes, It is best to ask your doctor about your eye examination schedule.


  • Inflammations

The tissue of the eye and each of its layers becomes inflamed. For example, inflammation can be caused by an allergy, or a virus such as the herpes simplex virus can cause inflammation. Improperly cleaning the lens of the eye and sleeping with the lens, not throwing the lens away at the end of the use period and many other cases can cause infection in the eye. Immune system diseases such as rheumatoid arthritis, inflammatory bowel disease, psoriasis and etc , can also be associated with eye inflammation.


  • Hypertension

If you feel weak and dizzy, it may be due to frequent and intermittent hypotension. Dehydration due to excessive activity in hot weather, use of medications and heart problems, malnutrition as well as hormonal imbalances may cause a drop in blood pressure. As a result of hypotension, the person experiences dizziness, lightheadedness, and blurred vision.


  • Low blood pressure

If you feel weak and dizzy, it may be due to frequent and intermittent hypotension due to dehydration due to excessive activity in hot weather, use of medications and heart problems, malnutrition, as well as hormonal imbalances may cause a drop in blood pressure. As a result of low blood pressure, the dizzy person experiences lightheadedness and blurred vision.


  • Accumulation of fluid in the eye

When fluid accumulates in the eye, pressure is applied to the optic nerves and the optic nerve fibers are damaged. You see halos around the light sources

And your eyes will be red and very painful.

This complication occurs very quickly and may destroy your vision within a day if not treated in time, but the more common types of glaucoma are open-angle glaucoma and usually do not affect vision at first.


  • Onset of migraines  /  visual auras in migraines

Statistics show that a quarter of patients with migraines develop vision problems before the onset of their headache and an hour before the onset of the headache. These problems, called migraine auras, as follows:

  • See lines of light
  • Luminous zigzag lines
  • Sparks
  • Arrows
  • See black spots as well as find tunnel views

The person may feel that he is looking around from behind a container of water or a broken glass

In some cases, these episodes of visual impairment may even occur after a headache or without the onset of the headache itself. If this only happens in one eye, you should see a doctor right away.


  • Cataracts

The part of the lens of the eye that should naturally be completely clear becomes cloudy for a variety of reasons, including aging. Cataracts develop slowly and usually involve both eyes. This complication usually appears after the age of 55, but cataracts can occur in young people and even children. Cataracts blur the vision of colors. Vision in the dark or so-called night vision is reduced and hardened. The eye becomes sensitive to light. There are special glasses and lenses that help improve vision in the early stages. These people constantly need to change the number of their glasses. Sometimes it becomes necessary to replace a opaque lens with a practical synthetic lens called a fico.


  • Aging

As a person in their fifth decade of life, they may find it difficult to do things that require close vision, such as reading a book. In these cases, your doctor may recommend that you wear appropriate glasses or contact lenses.


  • Scratches on the surface of the cornea

When the cornea is scratched, the person feels that a foreign object is left in the eye. No matter what happens, nothing can be found in his eyes. The cornea may be scratched following an injury and scratching with a nail, but moreover, dust or environmental pebbles may cause scratches on the surface of the cornea. In this case, it is usually recommended that the first thing a person does is Rinse eyes with clean water pressure. You should blink several times after washing to spread more tears on the surface of your eyes.

Remember that rubbing or touching the eyeball is forbidden. This will make the situation worse. If there is no improvement, we should see a doctor as soon as possible.


  • Retinal and macular damage

The retina is the sensitive membrane at the base of the eye. There is a sensitive point called the macula that if for any reason these parts are damaged, such as swollen or torn, part or all of the image will be lost, and it makes you not have the right vision. Improper diets, high cholesterol and uncontrolled diabetes mellitus increase the risk of problems such as retinal detachment and edema and macular edema.


  • MS

If the optic nerve is damaged, it is difficult to send messages from the eye to the brain. Doctors do not know exactly what causes optic nerve inflammation or optic neuritis. But 50% of people with the condition develop MS within 15 years of the disorder. It is said that the first sign of MS was vision problems.


  • Pregnancy and vision problems

Blurred vision along with headache, nausea and shortness of breath can be a sign of a very serious and dangerous complication called preeclampsia or pregnancy poisoning. Pregnancy poisoning occurs when the blood vessels in the placenta become narrow and the entire arteries of the placenta become dysfunctional.

The first sign of preeclampsia or pregnancy poisoning is considered by doctors to be high blood pressure after the twentieth week of pregnancy. In such cases, you should see a doctor sooner. This complication, if left untreated, can endanger the mother's life and take the mother's life. Preeclampsia can be managed with close control and care by the medical and drug team.

In the next part, we will go to the definition of lightheadedness and the causes of lightheadedness.


What is the lightheadedness?

Lightheadedness is when a person feels weak and faint, when the head feels a lack of blood supply. Another way to describe the lightness of the head is to use the title; feeling of stumbling which is often heard from the affected people. This condition is accompanied by blurred vision and loss of balance.

It can be said that often, lightheadedness does not have worrying causes, but you should know that sometimes lightheadedness can be a manifestation of a medical problem, an important field that increases the risk of falling.

When a person feels light-headed, he should be careful and try to sit in a safe place immediately. This complication occurs when a person changes position quickly For example, he moves from a sleeping position to a sitting position, or suddenly gets up and stands from a sitting position.

This change in state causes the blood flow to the brain to change, disrupting blood flow and oxygen supply to the brain.

It can also cause a drop in blood pressure that can make a person feel weak and faint. You should encourage these people to drink enough water and also be sure to urge them to see a doctor to find out the cause behind this lightheadedness.


What are the symptoms associated with lightheadedness?

Lightheadedness can be accompanied by other symptoms and manifestations. These symptoms can include the following:

  • Nausea
  • Feeling
  • The lack of balance
  • And instability in standing and moving

Many of these problems can be caused by problems with the inner ear, inflammation of the inner ear, brain and cardiovascular problems, as well as following the use of certain medications. Lightheadedness can be potentially dangerous.

In medicine, there is another term that refers to when a person feels that his surroundings are spinning around his head or that he is spinning around his surroundings. While in reality both of them are fixed to each other. This definition is equivalent to real dizziness in medicine.

Lightheadedness feels like swinging and floating. Most cases of lightheadedness can be caused by disorders of the inner ear, which, the signals that the ear sends to the brain, are inconsistent with the signals and signals that the eye and peripheral nerves receive, and these have caused the lightheadedness and Create imbalance in the person.

Another symptom that can be accompanied by lightheadedness is temporary vision changes, such as blurred vision and loss of visual acuity.


What causes lightheadedness?

The most common cause of lightheadedness is a sudden drop in blood pressure. When a person changes position and suddenly sits down from a sleeping position and suddenly stands up from a sitting position, this condition is called orthostatic hypotension by doctors.

Dehydration is also a very common cause that can be associated with lightheadedness. In addition to the two above that are common, namely orthostatic hypotension and dehydration, other common causes of lightheadedness are:

  • Colds
  • Flu
  • Lower blood sugar
  • Acrophobia
  • Allergies
  • Dehydration followed by vomiting and diarrhea

  • Fever and other diseases and problems
  • Alcohol, tobacco and drug use

Apart from these controllable factors, lightheadedness can occur due to more serious factors. Among these factors, the following can be mentioned:

  • Neurological problems such as Parkinson's disease and MS
  • Head injury
  • Problems with the inner ear
  • Strokes
  • Heart disease
  • Arrhythmias
  • Internal bleeding
  • Loss of large amounts of blood
  • As well as shocks that cause a significant reduction in blood pressure


How is lightheadedness treated?

The cause of lightheadedness, if it is followed by heavy bleeding or a heart attack, arrhythmia or stroke, should be treated urgently by the treatment team as soon as possible according to the treatment protocol.

If there is no lightheadedness to these causes, it often gets better over time. There are treatments for minor causes of lightheadedness that we will mention below.

Treatments for minor causes that lead to lightheadedness include:

  • Taking anti-migraine medications
  • Use of antiemetic drugs
  • And the use of drugs such as diazepines


Balance therapy, for example, the use of rehabilitation programs in which changes are made to reduce the sensitivity of the balance and movement system.

Psychotherapy is recommended to control anxiety and stress

Sometimes an antibiotic injection is used in the inner ear to treat ear disorders, which causes balance problems, which deactivates the ear, which causes a balance problem, and allows the other ear to regain balance.

Another method is to remove the sensitive organ of the inner ear, which is known as removing the labyrinth. This is a rare operation performed to disable the function of the inner ear. In fact, the balance problems created by this deactivation are eliminated and the other ear can establish balance.


Prevent lightheadedness
