Follow-up question #151697 Eye issues


Dear Dr.
He,
Thank you very much for your response and explanation regarding the eye issue in article #151697.
You mentioned that "seeing flashes is usually caused by the vitreous pulling on the retina," which I am aware of.
However, I have another phenomenon: when I turn my eyes to the extreme right, in addition to seeing flashes, I also hear a popping sound (similar to the sound of electrical wires short-circuiting).

I would like to ask you:
1.
In your experience, what is the cause of the popping sound (similar to the sound of electrical wires short-circuiting) that accompanies the flashes?
2.
Furthermore, could this popping sound (similar to the sound of electrical wires short-circuiting) have any impact or cause harm to my eyes?
Thank you, Dr.
He.

In my personal practice, I have never encountered the above situation, so I am unable to answer the questions you have raised.

More Info


Flashing lights and unusual sounds in the eyes can be concerning symptoms that warrant careful consideration. Based on the information provided, it appears that you are experiencing a phenomenon where you see flashes of light accompanied by a popping sound when you turn your eyes to the extreme right. This situation raises several important questions regarding the underlying causes and potential implications for eye health.

1. Understanding the Flashing Lights and Popping Sounds: The flashes of light you are experiencing are likely related to the vitreous body of the eye. The vitreous is a gel-like substance that fills the eye and is attached to the retina. When you move your eyes, especially to the extremes, the vitreous can pull on the retina, leading to the sensation of flashes of light. This is a common occurrence, particularly in individuals with myopia (nearsightedness) or those who have experienced changes in the vitreous due to aging or other factors.

The popping sound you describe, which resembles an electrical short circuit, is less common and may be attributed to a few different factors. One possibility is that it could be related to the movement of the vitreous or the muscles around the eye. When you turn your eyes sharply, the muscles and tendons may create a sound that you perceive as a pop. Another possibility is that it could be related to the auditory system, where the sound is not directly produced by the eye but rather by the movement of the head or neck, which can create sounds that resonate in the ear.

2. Potential Impact on Eye Health: As for whether this popping sound could cause any harm to your eyes, it is essential to differentiate between benign phenomena and those that may indicate a more serious condition. Generally, if the flashes of light and popping sounds are occasional and not accompanied by other symptoms such as significant vision changes, persistent pain, or an increase in floaters, they are likely benign. However, if you notice a sudden increase in the frequency of these flashes, or if they are accompanied by other concerning symptoms, it would be prudent to seek a comprehensive eye examination.

In summary, while the flashes of light are likely related to the normal physiological response of the vitreous pulling on the retina, the popping sound may require further investigation to rule out any underlying issues. It is always advisable to consult with an eye care professional if you have any concerns about your vision or if you experience new or worsening symptoms. Regular eye exams are crucial, especially for individuals with pre-existing conditions such as myopia, as they can help detect any potential problems early on.

In conclusion, while the experiences you describe may be common and benign, it is essential to remain vigilant about any changes in your symptoms. If you have any doubts or if your symptoms persist, do not hesitate to reach out to an eye specialist for a thorough evaluation. Your eye health is paramount, and proactive care can help ensure that any potential issues are addressed promptly.
