Q: Seeing Lightning in Your Eyes: Visual Disturbances After Surgery

Waking up to see flashes of light in my vision?

Hello, Doctor! Recently, when I wake up in the morning and blink, I often see shapes resembling blood vessels, like flashes of lightning, which have been occurring for over a week.
In the past few days, it seems that I also see them after taking a shower or before going to bed—just at the moment I blink, and then they disappear immediately.
I would like to ask what this situation might be.
Additionally, about three weeks ago, I underwent laser surgery to repair a retinal tear in my right eye.
Now, whenever I close my eyes, I see a slight green light—not very noticeable—just a bit of a green sensation in the central field of vision, and it does not appear at the site of the repaired tear.
Could you please explain what this might be? Thank you, Doctor!

More Info

Seeing visual disturbances such as flashes of light or "lightning" in your eyes can be concerning, especially after undergoing eye surgery like laser treatment for retinal tears. These phenomena can be attributed to several factors, and understanding them can help alleviate your worries.

1. Understanding Visual Disturbances: The flashes of light you are experiencing, often described as "lightning," are typically caused by the vitreous gel in the eye pulling on the retina. This is known as vitreous traction. When the vitreous gel, which is a clear, jelly-like substance that fills the eye, begins to shrink or pull away from the retina, it can stimulate the retinal cells, leading to the perception of flashes of light. This is a common occurrence, especially after surgeries that involve manipulation of the retina or vitreous, such as laser surgery for retinal tears.

2. Post-Surgical Changes: After your laser surgery for a retinal tear, it is not uncommon to experience visual disturbances as your eye heals. The surgery itself can cause changes in the vitreous gel, leading to sensations of light flashes. These flashes can be more noticeable during certain activities, such as blinking or moving your eyes quickly, which may explain why you see them when you wake up or after bathing.

3. Green Light Perception: The green light you see when your eyes are closed may be related to the healing process of the retina or the effects of the surgery. Sometimes, patients report seeing colors or light patterns due to the way the retina is responding to light or due to residual effects from the surgery. This phenomenon is often benign and may diminish as your eye continues to heal.

4. When to Seek Further Evaluation: While many visual disturbances post-surgery are normal and resolve over time, it is essential to monitor your symptoms. If the flashes of light become more frequent, if you notice a significant increase in floaters, or if you experience any changes in your vision (such as a curtain-like shadow), you should contact your eye care professional immediately. These could be signs of complications, such as retinal detachment, which requires prompt attention.

5. Follow-Up Care: Regular follow-up appointments with your ophthalmologist are crucial after any eye surgery. They can assess the healing process and determine if any further intervention is necessary. Your doctor may perform a dilated eye exam to check the health of your retina and vitreous.

6. Managing Anxiety: It is natural to feel anxious about changes in your vision, especially after surgery. Understanding that some visual disturbances are part of the healing process can help ease your concerns. However, maintaining open communication with your healthcare provider about your symptoms is vital.

In summary, the flashes of light and green light perception you are experiencing are likely related to the changes in your vitreous and retina following your recent laser surgery. While these symptoms can be common, it is essential to keep your eye doctor informed about any changes or concerns you have. Regular monitoring and follow-up care will help ensure your eyes heal properly and any potential issues are addressed promptly.

Your light sensitivity should still be intact; you are not completely blind, so having light perception is normal. As long as the corresponding stress is applied to the retina, there should be light perception.
