Eye Care: Addressing Retinal Detachment and Flashing Lights

Maintenance issues?

1.
I underwent gas treatment to reattach the detachment above my eye, but fluid has accumulated below.
The doctor recommended laser surgery to seal it.
After a week post-procedure, during my follow-up, the doctor mentioned that some areas were not adequately sealed and needed further treatment.
Could my use of electronic devices after the procedure have caused the treated areas to thin? The doctor only advised against lifting heavy objects.
2.
Although I experienced a detachment, I have no symptoms.
The doctor indicated that the hole I have does not affect my vision, which is why I have no symptoms.
I have only experienced flashes of light for the past year or two, which are persistent rather than intermittent.
3.
I would like to ask if the flashes I see, which extend from light bulbs, occur when I tilt my head back at a certain angle.
Is this considered a normal flash?

1.
Watching 3C devices does not cause thinning of the retina.
2 & 3.
The flashes you described are likely not caused by the retina, as true retinal flashes would feel like being flashed by a camera's flash and would typically disappear quickly.

When it comes to understanding eye care, particularly in the context of retinal detachment and the experience of flashing lights, there are several important factors to consider. Your situation involves a history of retinal issues, including gas treatment for retinal detachment and subsequent laser surgery. Let's address your questions systematically.

1. Post-Surgery Concerns: After undergoing gas treatment for retinal detachment, it is crucial to follow your doctor's advice regarding activity restrictions. The concern about whether using electronic devices (like computers or smartphones) could affect the healing process is valid. While there is no direct evidence that screen time can cause the laser-treated areas to thin, excessive eye strain can lead to discomfort and may exacerbate existing symptoms like flashing lights or floaters. It is advisable to take regular breaks from screens, practice the 20-20-20 rule (every 20 minutes, look at something 20 feet away for 20 seconds), and maintain a balanced lifestyle that includes proper hydration and nutrition to support eye health.

2. Symptoms and Monitoring: The fact that you have no significant symptoms despite having a retinal tear is somewhat reassuring. However, the presence of persistent flashing lights is noteworthy. Flashing lights can occur due to the vitreous gel pulling on the retina, which is common in individuals with a history of retinal issues. Since you have been experiencing these flashes for one to two years, it is essential to monitor them closely. If the frequency or intensity of the flashes increases, or if you experience new symptoms such as a sudden increase in floaters or a shadow in your vision, you should seek immediate medical attention. Regular follow-ups with your ophthalmologist are crucial to ensure that your retina remains stable.

3. Understanding Flashing Lights: The phenomenon of seeing light streaks or flashes, especially when looking at bright lights or when your head is tilted, can be attributed to the way light interacts with the retina and the vitreous body. When the vitreous gel pulls on the retina, it can create sensations of light flashes, which may be more pronounced in certain positions. This is generally considered a normal occurrence, especially in individuals with a history of retinal issues. However, if these flashes become more pronounced or occur in conjunction with other visual disturbances, it could indicate a need for further evaluation.

In summary, while some degree of flashing lights can be normal, especially after retinal surgery, it is essential to remain vigilant. Regular check-ups with your eye care provider are crucial for monitoring your condition. If you notice any changes in your vision or the nature of the flashes, do not hesitate to reach out to your ophthalmologist. Additionally, maintaining a healthy lifestyle and minimizing eye strain can contribute positively to your overall eye health. Always prioritize your eye care and follow your doctor's recommendations closely.
