After undergoing laser treatment for a retinal tear, there are still black spots present?


A few days ago, I noticed a small black spot in my vision.
Yesterday, I underwent laser treatment at Chang Gung Memorial Hospital, but today I still see the black spot.
Is this a normal phenomenon, or should I visit the clinic again?

Black spots are generally caused by floaters, and laser treatment cannot make floaters disappear; therefore, black spots typically do not go away.
This is for your reference.

Experiencing persistent black spots in your vision after undergoing laser treatment for a retinal tear can be concerning. It's important to understand that while some changes in vision can be expected following such procedures, any new or worsening symptoms should be taken seriously.

Firstly, it is not uncommon for patients to notice floaters or dark spots in their vision after laser treatment. This can occur due to the laser's impact on the vitreous gel in the eye, which may cause it to shift or pull away from the retina. These floaters can appear as small black dots, cobwebs, or even flashes of light. However, if these spots persist or if you notice an increase in their number, it is crucial to follow up with your eye care provider.

Here are some key points to consider regarding your situation:
1. Normal Post-Procedure Symptoms: After laser treatment for a retinal tear, some patients may experience transient visual disturbances, including floaters. These symptoms can be a normal part of the healing process. However, they should gradually improve over time.

2. When to Seek Further Evaluation: If the black spots remain persistent or if you experience any additional symptoms such as flashes of light, a sudden increase in floaters, or a shadow or curtain effect in your vision, it is essential to contact your eye doctor immediately. These could be signs of complications, such as a retinal detachment, which requires urgent attention.

3. Follow-Up Appointments: Regular follow-up appointments with your ophthalmologist are crucial after any retinal procedure. They can monitor your healing process and address any concerns you may have. If you haven't already scheduled a follow-up, it would be wise to do so.

4. Managing Symptoms: While you wait for your next appointment, try to avoid straining your eyes. This includes limiting screen time and ensuring you take breaks during activities that require intense focus. Staying hydrated and maintaining a healthy diet can also support overall eye health.

5. Understanding Floaters: Floaters are generally harmless, but their sudden appearance or increase can be alarming. They are often more noticeable against bright backgrounds or when looking at a plain surface. Over time, many people learn to ignore them as they become accustomed to their presence.

6. Long-Term Outlook: In many cases, floaters may diminish or become less bothersome as your brain adapts to them. However, if they are related to a more serious underlying issue, timely intervention is key to preserving your vision.

In summary, while some visual disturbances can be expected after laser treatment for a retinal tear, persistent black spots warrant further evaluation. It is always better to err on the side of caution when it comes to your vision. Schedule a follow-up with your eye care provider to discuss your symptoms and ensure that your eyes are healing properly. Your eye health is paramount, and proactive management is essential for maintaining good vision.
