Eye Flashes and Their Possible Causes: When to Seek Help - Ophthalmology

Share to:

I inquired about the meteorological conditions some time ago?


A few days ago, I inquired about the sensation of shooting stars around my eyes.
The frequency of these occurrences has decreased over the past few days, but occasionally I notice a bright spot in the corner of my eye that flickers like a light switch.
The occurrences are infrequent.
What could this situation indicate? Could it be a retinal tear or something similar? Should I get checked again? I had my pupils dilated on August 15, and there were no issues at that time, but I have high myopia, cataracts, and floaters, which makes me more anxious.
😓 Also, can eye problems cause headaches? Since my menstrual period is approaching, I can't distinguish which condition is causing the symptoms! Additionally, when I close my eyes, I experience flashes that seem to move from a bright area to a darker area and last for a while.
What could this typically indicate? Is it vitreous traction? Will it persist?

Hello: 1.
Flashes and floaters: The sensation of flashes and floaters may be related to changes in the vitreous body, such as vitreous traction or vitreous opacities.
These symptoms may occasionally occur, but if you notice a significant increase in their frequency or if they persist, it is advisable to have an eye examination to ensure the health of the retina and vitreous.
2.
Retinal tears: A retinal tear is a condition affecting the retina, often accompanied by symptoms such as flashes, floaters, or spots.
If there are signs suggesting a retinal issue, especially in cases of high myopia, it is best to seek an eye examination as soon as possible, as retinal tears may require treatment to prevent more serious retinal problems.
3.
Headaches: Eye problems can sometimes lead to headaches, particularly if you have been using your eyes for extended periods or if there is increased intraocular pressure.
However, headaches can also be caused by other factors, such as menstrual cycles.
If headaches persist or worsen, it is advisable to consult your physician for further evaluation.

More Info


Understanding eye flashes and their potential causes is crucial, especially for individuals with pre-existing eye conditions such as high myopia, cataracts, and floaters. Your description of experiencing flashes of light, particularly in the corners of your eyes, raises several important considerations.


Possible Causes of Eye Flashes
1. Vitreous Detachment: As we age, the vitreous gel that fills the eye can shrink and pull away from the retina. This process can cause flashes of light, often described as "lightning streaks" or "shooting stars." This is generally a normal occurrence but can sometimes lead to more serious conditions if the vitreous pulls too hard on the retina.

2. Retinal Tears or Detachment: Flashes of light, especially if accompanied by new floaters or a shadow in your vision, can indicate a retinal tear or detachment. This is a serious condition that requires immediate medical attention. Given your history of high myopia, you are at a higher risk for these issues.

3. Migraine Aura: Some individuals experience visual disturbances, including flashes of light, as part of a migraine aura. This can occur even in those who do not have a history of migraines. The symptoms typically resolve within 30 minutes to an hour.

4. Ocular Migraines: Similar to migraine aura, ocular migraines can cause temporary visual disturbances, including flashes of light, without the headache that usually accompanies migraines.

5. Dry Eyes: Dry eye syndrome can lead to visual disturbances, including flashes or a sensation of light. This is often exacerbated by prolonged screen time or environmental factors.

6. Other Neurological Causes: Although less common, visual disturbances can sometimes be related to neurological issues. If you experience persistent symptoms, it is essential to rule out these conditions.


When to Seek Help
Given your symptoms and medical history, it is advisable to seek further evaluation from an eye care professional. Here are specific indicators that warrant immediate attention:
- New or Increased Flashes: If the frequency or intensity of the flashes increases, it is crucial to get evaluated.

- Accompanied Symptoms: If you notice new floaters, a shadow or curtain effect in your vision, or any significant changes in your eyesight, seek help immediately.

- Persistent Symptoms: If the flashes continue or worsen over several days, a follow-up examination is necessary.


Connection Between Eye Issues and Headaches
Eye problems can indeed contribute to headaches. Strain from focusing, especially if you have uncorrected vision issues, can lead to tension headaches. Additionally, if you experience migraines, the visual disturbances may precede or accompany headache episodes. It’s essential to monitor your symptoms and discuss them with your healthcare provider, especially if they coincide with your menstrual cycle, as hormonal changes can also influence headache patterns.


Flashes When Closing Your Eyes
The flashes you experience when closing your eyes, particularly transitioning from a bright to a dark environment, may be related to the way your eyes adjust to light changes. This could be a normal physiological response, but if it persists or is accompanied by other symptoms, it’s worth discussing with your eye doctor.


Conclusion
In summary, while some flashes of light can be benign, your history of high myopia and other eye conditions necessitates a cautious approach. Regular eye examinations and open communication with your eye care provider are essential for monitoring your eye health. If you experience any concerning symptoms, do not hesitate to seek immediate medical attention. Your vision is invaluable, and proactive care is the best way to protect it.
