Eye Symptoms: Flashing Lights and Sounds When Moving Eyes - Ophthalmology

Eye problems


Dear Dr.
He,
When I turn my eyes to the right to the extreme limit, I experience flashes of light (similar to lightning) accompanied by popping sounds (similar to the sound of electrical wires short-circuiting).
However, there are no such phenomena when I move my eyes up, down, or to the left.
Currently, I do not have any discomfort or significant vision impairment.
I would like to ask you, Dr.
He:
1.
Based on your clinical experience or perspective, what condition or phenomenon is most likely affecting my eyes?
2.
In relation to the aforementioned condition or phenomenon, will it impact my vision or cause any impairment?
3.
What would be the best course of action for me at this time? (For example: seek immediate medical attention or continue to observe)
Thank you, Dr.
He.

Dr. He Jianxian reply Ophthalmology


Typically, seeing flashes of light is caused by the vitreous pulling on the retina.
It is recommended to consult an ophthalmologist for a dilated eye examination.
If the retina is found to be intact, simple monitoring is sufficient.
However, if there is any damage, laser treatment may be necessary.

More Info


When experiencing flashing lights and accompanying sounds while moving your eyes, particularly when looking to the right, it can be concerning and confusing. Based on your description, there are several potential explanations for these symptoms, and I will address your questions in detail.

1. Possible Conditions: The phenomenon you are experiencing could be related to several ocular conditions. The most common cause of flashing lights is the traction of the vitreous gel on the retina, which can occur when the vitreous body shrinks or pulls away from the retina. This is often benign, especially if there are no other symptoms such as significant vision loss or a curtain-like shadow in your vision. However, it is essential to rule out more serious conditions such as retinal tears or detachments, which can also cause similar symptoms. The sound you describe, akin to a popping or crackling noise, could be related to the movement of the vitreous gel or even the muscles around the eye contracting as you move your gaze.

2. Impact on Vision: If the flashing lights are indeed due to vitreous traction, they may not necessarily lead to vision loss. However, if there is a retinal tear or detachment, it could result in significant vision impairment if not treated promptly. It is crucial to monitor your symptoms closely. If you notice any changes in your vision, such as an increase in the frequency or intensity of the flashes, the appearance of new floaters, or any loss of peripheral vision, you should seek immediate medical attention.

3. Recommended Actions: Given your symptoms, it is advisable to consult an eye care professional, preferably an ophthalmologist, for a comprehensive eye examination. This examination should include a dilated fundus exam to assess the retina and vitreous gel thoroughly. If the examination reveals no significant issues, you may be advised to monitor your symptoms over time. However, if any abnormalities are detected, appropriate treatment can be initiated.

In summary, while your symptoms may not indicate a severe problem, it is essential to take them seriously. Regular eye exams are crucial, especially if you have a history of eye conditions or if your symptoms change. Maintaining eye health through proper care and regular check-ups can help prevent potential complications. If you have any further concerns or if your symptoms worsen, do not hesitate to seek medical advice promptly.
