Blurry Vision and Dizziness: Causes and Solutions

Blurred vision?

A few months ago, after finishing a physical education class, my vision around the eyes became blurry (not in the center, but around the edges), similar to how things look when viewing them through moving water.
After a while, my vision returned to normal, but then I started experiencing dizziness and headaches.
However, this eventually resolved itself.
Recently, during a walk for exercise, I experienced the same symptoms: first blurry vision, then dizziness.
After lying down to rest, I felt much better upon waking, but that day, any quick movement of my head would trigger dizziness again.
Is this an issue with my eyes? Thank you, doctor.

Dear "Sky Blue",
Your symptom description closely aligns with visual aura migraines.
Patients experiencing this type of migraine often report visual disturbances prior to the onset of a headache, such as wave-like patterns, flashes of light, dark spots, or a mosaic effect.
These symptoms typically occur about half an hour before the headache begins.
Standard analgesics are generally less effective for this type of headache, and medications specifically designed for migraines are recommended.
The exact cause of these issues is unknown, but they are often related to abnormal constriction of blood vessels in the brain.
It has also been found to have familial and constitutional links, and individuals who have experienced these migraines may have recurrent episodes.
If you are concerned, I recommend undergoing an ophthalmological examination; if no abnormalities are found, you can feel more at ease.
However, if the frequency of your episodes continues to be bothersome, you should consult a neurologist.
Wishing you good health,
Changhua Hospital

More Info

Blurry vision and dizziness can be concerning symptoms, and understanding their potential causes is crucial for proper diagnosis and treatment. Based on the symptoms you've described, it appears that you may be experiencing a combination of visual disturbances and vestibular (balance-related) issues. Let's break down the possible causes and solutions.

Possible Causes
1. Visual Disturbances: The initial symptom of blurry vision, particularly after physical exertion, could be related to several factors:
- Refractive Errors: If you have uncorrected refractive errors (like myopia or astigmatism), physical activity can sometimes exacerbate these issues, leading to temporary blurriness.

- Eye Fatigue: Engaging in physical activities can lead to eye strain, especially if you are not used to it or if you have been focusing on something for a prolonged period.

- Dry Eyes: Physical exertion can lead to decreased blinking, which may cause dry eyes and result in temporary blurriness.

2. Vestibular Issues: The dizziness you experience after blurry vision could indicate a vestibular problem:
- Vestibular Neuritis: This is an inner ear condition that can cause dizziness and balance issues, often triggered by viral infections.

- Benign Paroxysmal Positional Vertigo (BPPV): This condition occurs when tiny crystals in the inner ear become dislodged, causing brief episodes of dizziness with changes in head position.

- Migrainous Vertigo: If you have a history of migraines, they can sometimes present with dizziness and visual disturbances.

3. Neurological Causes: While less common, neurological issues could also be a factor:
- Transient Ischemic Attack (TIA): This is a temporary period of symptoms similar to those of a stroke. It is crucial to seek immediate medical attention if you suspect this.

- Multiple Sclerosis (MS): MS can cause a variety of neurological symptoms, including visual disturbances and dizziness.

4. Blood Pressure Fluctuations: Physical activity can lead to changes in blood pressure, which might cause dizziness, especially if you have orthostatic hypotension (a drop in blood pressure when standing up).

Solutions and Recommendations
1. Eye Examination: It is essential to have a comprehensive eye exam to rule out refractive errors, dry eyes, or other ocular conditions. An optometrist or ophthalmologist can provide a thorough evaluation.

2. Vestibular Assessment: If dizziness persists, consider consulting an ear, nose, and throat (ENT) specialist or a neurologist. They may perform tests to assess your vestibular function and determine if there is an underlying issue.

3. Monitor Symptoms: Keep a diary of your symptoms, noting when they occur, their duration, and any associated activities. This information can be valuable for your healthcare provider in diagnosing the issue.

4. Hydration and Nutrition: Ensure you are well-hydrated and maintain a balanced diet, as dehydration and low blood sugar can contribute to dizziness.

5. Gradual Movements: When transitioning from lying down to standing or moving your head, do so slowly to minimize dizziness.

6. Physical Therapy: If vestibular issues are diagnosed, vestibular rehabilitation therapy may help improve balance and reduce dizziness.

7. Follow-Up: If symptoms persist or worsen, follow up with your healthcare provider for further evaluation and management.

In conclusion, while blurry vision and dizziness can be related to eye problems, they may also indicate vestibular or neurological issues. A thorough evaluation by healthcare professionals is essential to determine the underlying cause and appropriate treatment. Always prioritize your health and seek medical attention if you experience concerning symptoms.
