Temporary White Fog in Vision: When to Seek Further Eye Care - Ophthalmology

More Info

---

The experience of temporary white fog in vision, particularly when accompanied by high myopia (nearsightedness) like your case with both eyes having over 800 degrees, can be concerning. The phenomenon you describe—seeing a white fog that appears momentarily when you turn your head—might be indicative of several underlying issues, and it’s essential to understand when further evaluation is necessary.

From your description, it seems that your eye doctor has already conducted a thorough examination, including a dilated fundus exam, and suggested that the symptoms could be related to vitreous liquefaction, which is often associated with posterior vitreous detachment (PVD). This condition can lead to the perception of floaters or flashes of light, but it can also cause temporary visual disturbances like the white fog you mentioned.


Understanding the Symptoms
1. Vitreous Changes: As we age or due to high myopia, the vitreous gel that fills the eye can begin to liquefy and pull away from the retina. This process can lead to symptoms like floaters or temporary visual disturbances. The white fog you experience could be a transient effect of this change, especially if it occurs during head movements.

2. Visual Perception: The fact that the fog appears only during specific movements and dissipates quickly suggests it may not be a constant issue like typical floaters. Instead, it could be related to how the vitreous interacts with the retina during those movements.

3. Differentiating from Other Conditions: While floaters are usually perceived as moving spots or strands, the white fog you describe is more akin to a transient visual disturbance. This could be due to a variety of factors, including changes in the vitreous, but it’s crucial to rule out more serious conditions.


When to Seek Further Eye Care
Given your history of high myopia and the recent onset of these symptoms, it’s advisable to monitor the situation closely. Here are some guidelines on when to seek further evaluation:
- Persistent Symptoms: If the white fog becomes more frequent, lasts longer, or is accompanied by other symptoms such as flashes of light, a sudden increase in floaters, or a shadow or curtain effect in your peripheral vision, you should seek immediate medical attention. These could be signs of retinal detachment, which is a medical emergency.

- Changes in Vision: Any significant changes in your overall vision, such as blurriness, difficulty focusing, or changes in color perception, warrant a visit to an eye care professional.

- Regular Check-ups: Given your high myopia, regular eye examinations are crucial. If you haven’t had a comprehensive eye exam in the last year, it would be wise to schedule one, even if your symptoms are currently mild.

- Consulting a Specialist: If your symptoms persist or worsen, consider consulting a retinal specialist. They can perform more detailed imaging tests, such as Optical Coherence Tomography (OCT), to assess the health of your retina and vitreous more thoroughly.


Conclusion
In summary, while your symptoms may be benign and related to vitreous changes, it’s essential to remain vigilant. Keep track of any changes in your vision and don’t hesitate to seek further evaluation if your symptoms evolve or worsen. Regular eye care is particularly important for individuals with high myopia, as they are at a higher risk for retinal issues. Always prioritize your eye health and consult with professionals when in doubt.
