Flashes of light in the eyes?


I had a fundus examination on Friday, but on Sunday night, I experienced flashes of light that lasted for 30 seconds.
Since then, there have been no further occurrences.
Should I be concerned or schedule a follow-up appointment?

At the Puzih Hospital Eye Clinic in Taiwan: Monday, Tuesday, Thursday, and Friday mornings from 8:00 AM to 12:00 PM, and Wednesday afternoons from 2:00 PM to 4:30 PM.
Online responses should only be used as a reference; it is still necessary to seek medical attention at a healthcare facility if needed.
I hope to have the opportunity to serve you.

Experiencing eye flashes after a fundus exam can be concerning, but it’s important to understand the context and the nature of these flashes. Eye flashes, often described as brief bursts of light in your vision, can occur for various reasons, including changes in the vitreous gel inside the eye, which is common as we age. However, they can also be indicative of more serious conditions, such as retinal detachment or other retinal issues.

In your case, since the flashes occurred after a fundus exam and lasted for only about 30 seconds without any recurrence, it may not be a cause for immediate concern. Fundus exams can sometimes lead to temporary changes in vision due to the dilation of pupils or the manipulation of the eye during the examination. However, it is crucial to monitor your symptoms closely.

Here are some key points to consider regarding eye flashes:
1. Nature of the Flashes: If the flashes are brief and infrequent, they might not be alarming. However, if they become persistent, increase in frequency, or are accompanied by other symptoms such as a curtain-like shadow over your vision, it is essential to seek medical attention promptly.

2. Associated Symptoms: Pay attention to any additional symptoms. If you experience a sudden increase in flashes, new floaters, or any changes in your peripheral vision, these could be signs of retinal issues that require immediate evaluation.

3. Follow-Up Care: Since you recently had a fundus exam, it’s advisable to follow your eye care provider's recommendations regarding follow-up appointments. If your symptoms change or worsen, do not hesitate to contact your eye doctor for further evaluation.

4. Understanding Risk Factors: Certain risk factors, such as high myopia (nearsightedness), a history of eye trauma, or previous retinal issues, can increase the likelihood of serious conditions associated with eye flashes. If you have any of these risk factors, it’s even more important to be vigilant about changes in your vision.

5. Anxiety and Eye Health: It’s natural to feel anxious about changes in your vision, especially if you have a history of eye problems. Stress and anxiety can sometimes exacerbate the perception of visual disturbances. Engaging in relaxation techniques and ensuring you get adequate rest can help manage anxiety levels.

6. Consultation: If you have any doubts or if the flashes recur, it’s always best to consult with your eye care professional. They can perform a thorough examination to rule out any serious conditions and provide peace of mind.

In summary, while a brief episode of eye flashes following a fundus exam may not be a cause for alarm, it is essential to remain observant of your symptoms and consult with your eye doctor if anything changes. Regular eye exams and open communication with your healthcare provider are key to maintaining good eye health.
