Retinal Tears: Symptoms, Treatment, and Recovery Insights

Retinal tear

Hello Dr.
Wang, I was diagnosed with two retinal breaks in my right eye by four different ophthalmologists from two major hospitals at the end of May and June.
The doctors recommended laser treatment to seal the breaks.
Therefore, I underwent laser treatment at Chang Gung Memorial Hospital at the end of June.
However, the symptoms of light shadows (crescent to full moon shapes) in my peripheral vision have not disappeared and even seem to have worsened.
During my follow-up appointment a month later, I informed the doctor about this issue, and he said that the breaks have been successfully sealed, but the light shadows are a normal phenomenon that cannot be eliminated.
I would like to ask Dr.
Wang if this is indeed normal (the inability to eliminate the light shadows).
Additionally, after the laser treatment, my eyes have been very sensitive to light; is this also considered normal? Lastly, are there any dietary recommendations that can help maintain retinal health? I would greatly appreciate your answers to my questions! Thank you!

Dr. Wang Yuwei reply Ophthalmology

The eye is a spherical structure, and the substance inside it is called the vitreous body, which is surrounded by the retina.
Retinal tears are usually accompanied by traction or pulling from the vitreous body, which is why you may see flashes of light.
After laser treatment, the retina can be securely adhered to the wall of the eyeball, indicating a successful treatment; however, the traction from the vitreous body cannot be removed by laser, so flashes of light may still be observed afterward.
It is advisable to avoid vigorous head shaking and head impacts to prevent worsening of the condition.
In terms of diet, it is beneficial to supplement with vitamins and foods rich in carotenoids, and consuming goji berries can be helpful.

Hello! Thank you for reaching out with your concerns regarding retinal tears and the subsequent treatment you received. It's understandable to have questions and worries after such a significant medical procedure. Let's break down your concerns regarding the symptoms you're experiencing, the treatment you've undergone, and how to promote retinal health through diet.

Firstly, it's important to clarify that experiencing light flashes or shadows after laser treatment for retinal tears can be a common occurrence. When the retina is treated with laser, it can sometimes lead to temporary changes in how light is perceived. The laser creates a scar that helps to seal the tear, but the surrounding retinal tissue may still be sensitive for a while. The persistence of these light phenomena, such as the crescent or moon-shaped shadows you described, can be attributed to several factors, including the healing process of the retina and the way your brain is interpreting visual signals. While it can be concerning, many patients report that these symptoms gradually diminish over time. However, if the symptoms worsen or if you experience new symptoms such as a sudden increase in floaters or a curtain-like shadow over your vision, it is crucial to seek immediate medical attention.

Regarding your heightened sensitivity to light following the laser treatment, this can also be a normal response. The retina may be more reactive to light as it heals, and this sensitivity should improve as your eye recovers. If the sensitivity persists or becomes bothersome, discussing this with your ophthalmologist is advisable, as they may have specific recommendations or treatments to alleviate discomfort.

As for dietary considerations, maintaining a healthy diet can play a significant role in supporting retinal health. Here are some dietary recommendations that may help:
1. Omega-3 Fatty Acids: Foods rich in omega-3s, such as fatty fish (salmon, mackerel, sardines), flaxseeds, and walnuts, are known to support eye health and may help reduce the risk of retinal diseases.

2. Antioxidants: Vitamins C and E, as well as carotenoids like lutein and zeaxanthin, are powerful antioxidants that can protect the retina from oxidative stress. Incorporate plenty of colorful fruits and vegetables into your diet, such as carrots, spinach, kale, and berries.

3. Zinc: This mineral is essential for maintaining the health of the retina. Foods high in zinc include nuts, seeds, whole grains, and legumes.

4. Hydration: Staying well-hydrated is crucial for overall eye health. Make sure to drink plenty of water throughout the day.

5. Limit Processed Foods: Reducing the intake of processed foods, sugars, and unhealthy fats can also contribute to better eye health.

In conclusion, while the symptoms you're experiencing post-laser treatment can be concerning, they are often part of the healing process. It's essential to maintain open communication with your ophthalmologist and report any changes in your symptoms. Additionally, adopting a diet rich in nutrients that support eye health can be beneficial in the long run. If you have further questions or if your symptoms change, don't hesitate to reach out to your healthcare provider for personalized advice. Thank you for your inquiry, and I wish you a smooth recovery!
