Eye problems

Hello, Doctor.
I would like to ask about something that happened just now.
While I was taking a shower, I suddenly saw a flash of light for 1-2 seconds.
I'm not sure if it was just the bathroom light flickering, as it felt like the flash came from that direction.
A few weeks ago, I had a dilated eye exam, and the doctor said everything was fine and healthy.
They even used a strange instrument to check my retina, which looked like a donut or a volcano—I'm not quite sure.
The doctor mentioned that my floaters would not go away and that I would have to coexist with them.
I also had an eye exam earlier this year.
I would like to know if the flashes I experienced are similar to what is typically described by doctors.
Additionally, do these flashes need to occur multiple times? My family says I might be too anxious, and that the flash could just be a problem with the light.
I would like to hear your opinion on whether I should get another dilated eye exam or if I should just observe the situation for now.
Thank you, and Happy New Year!

Hello: The sensation of flashes may be a physiological phenomenon of the eye, but it can sometimes indicate a retinal issue.
Flashes are typically described as sudden bursts of light that can last for a few seconds or even shorter.
This phenomenon is usually caused by changes in the internal structure of the vitreous body, such as vitreous opacities or traction on the retina.
However, flashes can also be a precursor to retinal detachment.
When the retina separates from the back of the eye, it may produce a sensation of flashes.
This condition is often accompanied by other symptoms, such as a sudden increase in floaters, black spots, or shadows in the visual field.
Since your recent eye examination showed no issues and the doctor did not indicate any serious problems, it is advised to monitor the situation.
If the flashes occur only occasionally and are not accompanied by other symptoms, immediate medical attention may not be necessary.
However, if the flashes occur frequently, increase in intensity, or are accompanied by other concerning symptoms, I recommend seeking medical attention as soon as possible.

More Info

When it comes to experiencing flashes of light in your vision, especially if you have a history of eye conditions such as myopia or floaters, it is essential to understand the potential implications and when to seek further medical advice. Based on your description, it seems you experienced a brief flash of light while in the shower, which you suspect may have been caused by the bathroom light flickering. This situation raises a few important points to consider.

Firstly, flashes of light, also known as photopsia, can occur for various reasons. In some cases, they may be benign and related to the normal functioning of the eye, such as the stimulation of the retina or the vitreous gel pulling away from the retina. However, in individuals with high myopia or a history of retinal issues, flashes can sometimes indicate more serious conditions, such as retinal tears or detachment.

Given that you recently underwent a thorough eye examination, including dilation, and were informed that your retina appeared healthy, it is reassuring. However, it is crucial to remain vigilant. If the flashes of light become more frequent, last longer, or are accompanied by other symptoms such as a sudden increase in floaters, a shadow or curtain effect in your vision, or a significant decrease in vision, you should seek immediate medical attention. These symptoms could indicate a more serious issue that requires prompt evaluation.

In your case, since the flash you experienced was brief and may have been related to an external light source, it might not be a cause for concern. However, if you find yourself frequently questioning whether your symptoms warrant further investigation, it is always better to err on the side of caution. If you experience additional flashes or any new symptoms, it would be prudent to schedule another appointment with your eye care professional for a comprehensive evaluation.

Moreover, anxiety and stress can exacerbate your perception of visual disturbances. If you feel that your anxiety is affecting your vision or overall well-being, consider discussing this with your healthcare provider. They may recommend strategies to manage stress, which can, in turn, help alleviate some of the visual symptoms you are experiencing.

In summary, while your recent eye examination suggests that your retina is in good condition, it is essential to monitor your symptoms closely. If you experience any changes or new symptoms, do not hesitate to seek further evaluation. Regular check-ups with your eye doctor are vital, especially with your history of myopia and floaters. Remember, your eye health is paramount, and staying informed about your symptoms will empower you to make the best decisions for your vision. Happy New Year, and take care of your eyes!
