Persistent Visual Disturbances: Are They Signs of Retinal Degeneration?

Q: Persistent Visual Disturbances: Are They Signs of Retinal Degeneration?

Flashing, flickering, lightning—it's hard to describe?

In mid-June, I underwent a dilated eye exam, and the doctor explained that there were no symptoms, only the presence of floaters.
Since I have not experienced any retinal tears or detachments, the doctor advised that I only need to have an examination once a year.
During the exam, I also mentioned a situation that I am unsure how to describe—whether it is "flashes, lightning, flickering, or wavy lines." However, since the dilated eye exam showed no abnormalities, does this mean I do not need to be overly concerned?
Nonetheless, the "flashes, lightning, flickering, wavy lines" I described have been continuously present (24 hours a day, except when I am asleep; they are also present when my eyes are closed).
Although there is no significant increase in floaters or blurred vision, I can perceive flashes and flickering when I focus on darker areas.
I have high myopia and floaters due to cataracts, which makes me more anxious.

In summary, I would like to ask the doctor if this condition could be a sign of "retinal degeneration." Is there anything specific I should be particularly aware of?

Hello: Based on the symptoms you described, the persistent phenomenon of "flashes, lightning, flickering, and water patterns," which occurs even when your eyes are closed, is indeed concerning.
However, since you underwent a dilated eye examination in mid-June and no abnormalities were found by the physician, that is certainly good news.

1.
Retinal Degeneration: While you are worried about retinal degeneration, if no holes or detachments were detected during your recent dilated examination, there may not be a need for excessive concern at this time.
However, the health of the retina should be continuously monitored, especially for individuals like you who have high myopia and floaters.
2.
Visual Snow: The condition you mentioned, visual snow, does share some similarities with the symptoms you described.
Visual snow is characterized by the presence of persistent tiny flickering dots in the visual field, resembling the static seen on a television with no signal.
Currently, there is no specific treatment for this condition, but symptoms can be alleviated through certain medications or lifestyle adjustments.
It is advisable to consult a neuro-ophthalmologist or neurologist for further evaluation to determine if it is indeed visual snow.
3.
Environmental Factors: Spending long periods indoors and lacking natural light may affect eye health.
It is recommended to increase outdoor activity time to allow your eyes to receive stimulation from natural light, which can help maintain visual health.
4.
Precautions:
- Regular Eye Exams: Even if no abnormalities are currently detected, it is still necessary to have an eye examination annually, especially for individuals with high myopia and floaters.
- Monitor Symptom Changes: If the flashing phenomena suddenly increase, or if you experience blurred vision or a significant increase in floaters, please seek an eye examination immediately, as this may be a warning sign of retinal issues.
Finally, while there is currently no cure for visual snow, symptoms can be managed through lifestyle adjustments and appropriate treatment.
Wishing you good health!

More Info

Understanding persistent visual disturbances, especially in the context of retinal health, can be quite concerning. Based on your description, it seems you are experiencing ongoing visual phenomena such as flashes, flickers, or wave-like patterns. While these symptoms can be alarming, it's important to contextualize them within your recent eye health evaluations and existing conditions.

Firstly, you mentioned that you underwent a dilated eye exam in June, during which your ophthalmologist found no signs of retinal tears or detachments. This is a positive indication, as these conditions can lead to serious vision loss if left untreated. The fact that your doctor advised annual check-ups suggests that they are monitoring your eye health appropriately, especially given your history of high myopia (nearsightedness) and floaters.

The visual disturbances you describe—flashes, flickers, or wave-like patterns—can sometimes be attributed to a phenomenon known as "visual snow" or other forms of visual disturbances that are not necessarily indicative of retinal degeneration. Visual snow is characterized by a persistent perception of tiny flickering dots across the visual field, similar to the static seen on a television screen without a signal. While this condition can be distressing, it is not typically associated with retinal damage.

However, it is crucial to remain vigilant about any changes in your symptoms. Here are some key points to consider:
1. Monitor Symptoms: Keep a close eye on any changes in your visual disturbances. If you notice an increase in the frequency or intensity of the flashes, or if you begin to experience new symptoms such as significant vision loss, blurred vision, or a sudden increase in floaters, it is essential to seek immediate medical attention.

2. Regular Eye Exams: Continue with your annual eye exams, as recommended by your ophthalmologist. Regular check-ups are vital for monitoring the health of your retina, especially given your high myopia, which increases the risk of retinal issues.

3. Environmental Factors: Consider your environment and lifestyle. Prolonged exposure to screens, inadequate lighting, and lack of outdoor activity can contribute to visual fatigue and disturbances. Ensure you take regular breaks when using digital devices and maintain a healthy balance of indoor and outdoor activities.

4. Consult a Specialist: If your symptoms persist or worsen, consider consulting a neuro-ophthalmologist or a retina specialist. They can provide a more in-depth evaluation of your symptoms and rule out any underlying neurological or retinal conditions.

5. Manage Anxiety: It's natural to feel anxious about your vision, especially with a history of eye conditions. Engaging in relaxation techniques, such as mindfulness or yoga, may help alleviate some of the stress associated with your symptoms.

In conclusion, while your current symptoms may not necessarily indicate retinal degeneration, it is essential to remain observant and proactive about your eye health. Regular check-ups and open communication with your healthcare provider will help ensure that any potential issues are addressed promptly. Remember, maintaining a healthy lifestyle and managing screen time can also contribute positively to your overall eye health.
