Blurry vision and dizziness frequently take place together because of the complex relationships in between visual processing and other organ systems of the body. In addition to conditions of the eye, blurry vision and dizziness can be caused by systemic conditions, diseases of the nervous system, complications of cardiovascular disease and other medical conditions. Treatment for blurry vision and dizziness differs, depending upon the underlying cause.
Dizziness and Blurred Vision: Diseases Related These Symptoms
Any problem with the eyes that causes blurry vision and distorted perception can cause a feeling of dizziness. For example, individuals with nearsightedness, farsightedness, astigmatism or presbyopia– age-related problem seeing near objects– may occasionally experience bouts of dizziness along with blurry vision. Cataracts are another common eye ailment that can lead to blurry vision and mild dizziness. Even pregnancy-related eye changes can result in periods of distorted vision and dizziness. Although some vision changes that can cause dizziness do not reflect a serious medical issue, it is very important to have any change in vision evaluated by an optometrist, especially if the change happens unexpectedly.
Anything that decreases blood flow to the brain can lead to dizziness and blurry vision. When this develops unexpectedly, it usually feels as though fainting will take place. Individuals with heart failure typically experience these episodes, specifically when getting up from sitting or lying down. A heart attack might set off the same symptoms. Some types of heart valve or rhythm problems can cause comparable episodes. Severe dehydration due to overheating or long term vomiting or diarrhea can cause low blood pressure with dizziness and blurry vision. Specific blood pressure and heart medications can also cause these symptoms.
Nervous System Conditions
Lots of conditions can affect the nerves and brain centers associated with vision, resulting in blurred vision and dizziness. A head injury, stroke or rupture of a blood vessel in the brain cause unexpected symptoms. Infections of the brain and surrounding tissues might also activate these and other nervous system symptoms. Growths and chronic brain conditions, such as multiple sclerosis, frequently cause more subtle and transient symptoms.
Several other medical conditions that cause vision problems may cause blurry vision and dizziness. People living with diabetes might experience these symptoms when their blood glucose levels are high. Severe anemia might cause dizziness and blurred vision because of minimized oxygen delivery to the brain and low blood volume, according to iytmed.com. Thyroid problems, adrenal gland disorders and severe kidney disease are among the numerous other medical conditions that in some cases cause blurred or misshaped vision and dizziness.
See Your Doctor
Because blurry vision and dizziness can accompany a broad variety of medical conditions, it is very important to see your doctor for a precise diagnosis. Look for immediate medical treatment if you experience a sudden change in vision with dizziness, particularly if accompanied by other symptoms.
