Eye Flashes: Should You Seek Further Evaluation? - Ophthalmology

Hello! Thank you for reaching out with your concerns regarding the persistent flashes and floaters in your vision. It’s understandable to feel anxious about these symptoms, especially given your history of floaters and the recent changes you’ve experienced. Let’s break down your questions and concerns regarding eye flashes and the need for further evaluation.


Understanding Flashes and Floaters
1. Flashes and Floaters: Floaters are often caused by changes in the vitreous gel that fills the eye, which can become more liquid and pull away from the retina as we age. This is a common occurrence and can lead to the perception of floaters. Flashes, on the other hand, are typically caused by the vitreous pulling on the retina, which can create a sensation of light or flashes in your vision.
2. Evaluation of Symptoms: Since you have already undergone a dilated eye exam and your retina was found to be normal, this is reassuring. However, if you notice a significant increase in the frequency or intensity of the flashes, or if you experience new symptoms such as a sudden increase in floaters, shadows in your vision, or a curtain-like effect, it is crucial to seek immediate evaluation. These could be signs of retinal tears or detachment, which require prompt attention.

3. Persistent Flashes: The fact that you are experiencing persistent flashes could be related to the ongoing changes in the vitreous. It’s not uncommon for people with floaters to also experience flashes, and while it can be distressing, it does not always indicate a serious problem. However, if this is a new symptom for you, it’s worth discussing further with your eye care provider.

4. Adaptation: Many people learn to adapt to the presence of floaters and flashes over time. While they may not completely go away, your brain can often learn to ignore them. However, if the flashes are bothersome or if they worsen, it’s important to keep your eye doctor informed.


When to Seek Further Evaluation
- Increased Symptoms: If you notice that the flashes are becoming more frequent or intense, or if you develop new visual symptoms, it’s advisable to return to your eye doctor or seek a second opinion. Regular monitoring is essential, especially for individuals with a history of floaters or other eye conditions.

- Understanding Flashes: Flashes can vary in intensity and frequency. If you experience a sudden increase in the number of flashes, or if they appear in a different pattern than before, this could warrant further investigation.


Regarding Your Medication
- Use of Eye Drops: You mentioned being prescribed a medication called "Scopalamine" (散克巴). It’s important to consult your eye care provider regarding the use of any eye drops while wearing contact lenses. Some medications can cause dryness or irritation, which may be exacerbated by contact lens wear.


Conclusion
In summary, while your recent eye exam showed no immediate issues, it’s essential to stay vigilant about any changes in your vision. If you feel uncertain or anxious about your symptoms, don’t hesitate to seek further evaluation. It’s better to be cautious when it comes to eye health. Regular check-ups and open communication with your eye care provider are key to managing your concerns effectively.

If you have any more questions or need further clarification, feel free to ask. Your eye health is important, and it’s great that you’re taking proactive steps to understand and manage your symptoms.
