Visual Phenomena: Active Light Patterns with Eyes Closed

Q: Visual Phenomena: Active Light Patterns with Eyes Closed

When closing the eyes, the play of light and shadow becomes very active?

Hello Doctor: In the past few days, when I close my eyes in the dark, the light and shadows I see are more active than usual.
Sometimes, I even see a group of light spots flashing rhythmically.
Today, I even experienced a moment where I saw a whole field of white light, as if someone suddenly turned a light on and then off again.
(This has happened several times.) I would like to ask the doctor: 1.
Is this a physiological phenomenon of visual phosphenes, or should I be concerned about these flashes? 2.
I was recently diagnosed with migraines; could this be a visual symptom related to my migraines? Thank you for taking the time to respond, Doctor.

Hello: Based on the symptoms you described, the phenomena of light shadows and spots may involve several different causes.

1.
Physiological phosphenes? Seeing light shadows or spots with closed eyes in the dark is a relatively common phenomenon known as "physiological phosphenes." These phosphenes are usually caused by spontaneous activity in the retina or visual pathways, and they are more likely to be noticed in quiet or dark environments.
2.
Flashes that require attention? However, the description of a broad white light and rhythmic flickering, especially the sensation of lights suddenly turning on and off, may indicate flashes that require attention.
These flashes could be related to retinal traction or tears, which necessitate an immediate ophthalmologic examination to rule out the risk of retinal tears or detachment.
3.
Visual symptoms of migraine? You mentioned that you were recently diagnosed with migraines, which could also be a cause of the visual symptoms.
Migraines often accompany visual auras, such as flashes, zigzag lines, or visual field defects.
These symptoms typically occur before or during a migraine attack and are caused by activity in the brain areas that process visual information.
Recommendations:
1.
If these light phenomena occur frequently or are accompanied by other visual issues (such as blurred vision or visual field loss), you should seek an ophthalmologic examination as soon as possible to ensure retinal health.
2.
Discuss with your neurologist to see if these visual symptoms are related to your migraines and to confirm whether any adjustments to your treatment plan are necessary.
In summary, these phenomena may be benign physiological responses, but they could also indicate potential ophthalmic issues or migraine-related symptoms.
Early ophthalmologic evaluation and discussion with your neurologist are essential to ensure your eye and overall health.
Wishing you a speedy recovery.

More Info

The visual phenomena you are experiencing, particularly the active light patterns and rhythmic flashes of light while your eyes are closed, can be intriguing and concerning. Let's break down your questions and provide some insights based on medical knowledge.

1. Physiological Visual Phenomena vs. Concerning Symptoms: The phenomenon of seeing light patterns or flashes when your eyes are closed can indeed be a physiological response. This is often referred to as "phosphene," which is the perception of light without light actually entering the eye. Phosphenes can occur due to pressure on the retina, spontaneous activity in the visual system, or even as a result of neural activity in the brain. In a dark environment, the contrast between the absence of light and the internal visual stimuli can make these sensations more pronounced. However, if these visual disturbances are new, persistent, or accompanied by other symptoms (like headaches, vision loss, or other neurological signs), it is essential to consult with an eye care professional or a neurologist to rule out any underlying conditions.

2. Connection to Migraine: You mentioned that you have recently been diagnosed with migraines. Visual disturbances, including flashes of light, zigzag patterns, or even temporary vision loss, can indeed be associated with migraine aura. This is a phenomenon that occurs in some individuals before or during a migraine attack. The visual symptoms can vary widely among individuals, and they may last from a few minutes to an hour. If your visual disturbances coincide with headache episodes, it could be related to your migraine condition. However, it’s crucial to differentiate between typical migraine aura and other potential causes of visual disturbances, especially if the symptoms are changing or worsening.

Additional Considerations
- Eye Health: Given your history of high myopia and other visual symptoms, it is advisable to have regular comprehensive eye exams. High myopia can increase the risk of retinal issues, including tears or detachments, which can also manifest as flashes of light or visual disturbances.
- Neurological Evaluation: If the visual phenomena persist or are accompanied by other neurological symptoms (such as severe headaches, dizziness, or changes in coordination), a neurological evaluation may be warranted. Conditions like retinal detachment, vitreous detachment, or even neurological conditions can sometimes present with similar symptoms.

- Lifestyle Factors: Stress, fatigue, and dehydration can exacerbate migraine symptoms and may also influence visual phenomena. Maintaining a healthy lifestyle, managing stress, and ensuring adequate hydration can be beneficial.

- When to Seek Help: If you experience sudden changes in your vision, such as a significant increase in the frequency or intensity of the light patterns, or if you notice any new symptoms like vision loss, it is crucial to seek immediate medical attention.
In conclusion, while the visual phenomena you are experiencing could be benign and related to physiological processes or migraine, it is essential to monitor the symptoms closely. Regular check-ups with an eye care professional and a neurologist can help ensure that any potential issues are addressed promptly. Always prioritize your health and seek professional advice when in doubt.
