Visual Noise: What Causes TV-Like Disturbances in Vision? - Ophthalmology

More Info

---

Dear Patient,
Thank you for sharing your concerns regarding the visual disturbances you are experiencing. Your description of seeing a "TV-like disturbance" or "visual noise" when closing your eyes, particularly in relation to the activation of electrical appliances, raises several interesting points that merit further exploration.


Understanding Visual Noise
Visual noise, as you describe it, can be understood in several contexts. It often refers to the perception of random patterns or disturbances in one's visual field, which can occur under various circumstances. In your case, the phenomenon seems to be linked to external stimuli, such as the activation of electrical devices. This could suggest a heightened sensitivity of your visual system to environmental changes, which may be influenced by several factors.


Possible Causes
1. Visual Snow Syndrome: This condition is characterized by the perception of visual "snow" or static, similar to what you describe. It can occur in various lighting conditions and may be exacerbated by stress or fatigue. Individuals with visual snow often report seeing small, flickering dots in their visual field, which can be more pronounced in low-light situations.

2. Phosphenes: These are the sensations of seeing light without light actually entering the eye. They can occur when pressure is applied to the eyes or during moments of extreme fatigue. The phenomenon you experience when closing your eyes could be related to this, especially if you notice it more when transitioning from light to dark environments.

3. Neurological Factors: The brain's processing of visual information can sometimes lead to visual disturbances, especially if there are fluctuations in electrical activity. This could explain why you notice these disturbances when electrical appliances are activated. The brain's response to external stimuli can sometimes manifest as visual sensations.

4. Eye Health: Given your history of high myopia and other visual symptoms, it is essential to consider that changes in your eye health could contribute to these experiences. Conditions such as retinal issues or vitreous detachment can lead to various visual disturbances, including flashes or floaters.


Recommendations
1. Consult an Eye Specialist: Given the complexity of your symptoms, it would be prudent to consult with an ophthalmologist or a neuro-ophthalmologist. They can conduct a thorough examination to rule out any underlying eye conditions that may be contributing to your visual disturbances.

2. Keep a Symptom Diary: Documenting when these disturbances occur, their duration, and any accompanying symptoms can provide valuable information for your healthcare provider. Note any correlations with environmental factors, such as the use of electrical devices.

3. Manage Stress and Fatigue: Stress and fatigue can exacerbate visual disturbances. Implementing relaxation techniques, ensuring adequate sleep, and managing screen time can help alleviate some symptoms.

4. Consider Neurological Evaluation: If your symptoms persist or worsen, a referral to a neurologist may be warranted to explore any potential neurological causes for your visual disturbances.


Conclusion
Your experience of visual noise, particularly in relation to electrical stimuli, is intriguing and warrants further investigation. While some of these sensations may be benign, it is essential to ensure that there are no underlying issues that need to be addressed. I encourage you to seek a comprehensive evaluation from a qualified specialist who can provide you with a clearer understanding of your symptoms and appropriate management strategies.

Thank you for reaching out, and I hope this information helps clarify your concerns. Please feel free to ask any further questions or share additional details about your experience.
