Post-Laser Treatment Effects on Retinal Health - Ophthalmology

Post-retinal laser treatment


Hello, doctor.
I have high myopia, which has caused some peripheral retinal degeneration.
Previously, my right eye was accidentally hit by a hand, and the next day I experienced flashes of light.
I immediately went to a general ophthalmologist for a dilated fundus examination.
The doctor mentioned that there was a retinal tear and referred me to a larger hospital for further evaluation.
After the examination at the larger hospital, the doctor stated that there was no tear, just thinning of the retina, but recommended laser treatment for reinforcement, which I received immediately.
The doctor said he performed a circumferential laser treatment.
However, afterward, when I looked up, I noticed a slight white haze in the lower right part of my vision.
Since the pupil was not dilated, I was advised to return for a follow-up in two weeks.
During that follow-up, I mentioned this issue to the doctor, who examined my fundus and noted that there was some fibrous traction at the edge of the laser treatment area that needed reinforcement.
Therefore, I underwent another laser treatment.
The doctor mentioned that the white haze would gradually disappear in about 2 to 3 weeks.
Is it normal to experience this after laser treatment? Also, does the presence of the white haze indicate that it is close to the visual center? Thank you, doctor.
I appreciate your help.

The sensation of white fog is usually caused by localized opacities in the vitreous body.
It is advisable to have another physician examine the fundus to understand the situation better.

After undergoing laser treatment for retinal health, particularly in the context of high myopia and associated retinal degeneration, it is essential to understand the potential effects and recovery process. Your experience with the laser treatment, including the subsequent white haze you are noticing, raises several important points that merit discussion.

Firstly, it is not uncommon for patients to experience visual disturbances following retinal laser treatments. The white haze you describe can be attributed to several factors, including the healing process of the retina after laser application. When laser energy is applied to the retina, it creates a controlled injury that stimulates healing and strengthens the retinal tissue. This healing process can temporarily alter your vision, leading to sensations such as blurriness or a haze, particularly in the treated area. The fact that your doctor indicated this haze should diminish over the next few weeks is a positive sign that your eye is healing.

Regarding the concerns about the laser treatment affecting your vision, it is important to note that while the laser is designed to target specific areas of the retina, it does not typically damage surrounding tissues such as the cornea or lens. The focused nature of laser energy minimizes collateral damage, which is one of the reasons why laser treatments are favored in ophthalmology. However, some patients may experience transient visual disturbances as the retina adjusts post-treatment.

The presence of a white haze, especially if it is localized to the area where the laser was applied, suggests that the treatment is having its intended effect. The additional laser treatment your doctor recommended to reinforce the initial application is a common practice, particularly if there are signs of traction or if the initial treatment did not fully address the area of concern. This follow-up treatment aims to ensure that the retinal tissue remains stable and to prevent further complications.

It is also crucial to monitor your symptoms closely. If the white haze persists beyond the expected recovery period or if you experience any new symptoms, such as increased flashes of light, new floaters, or a significant change in vision, you should contact your eye care provider immediately. These could be signs of complications that require further evaluation.

In summary, experiencing a white haze after retinal laser treatment can be a normal part of the healing process. The fact that your doctor is actively monitoring your condition and has provided additional treatment indicates a proactive approach to your care. As your eye heals, it is likely that the haze will gradually resolve, restoring your vision to its optimal state. Always feel free to discuss any concerns with your healthcare provider, as they can provide personalized insights based on your specific situation and medical history.
