Retinal issues

Hello Doctor: I have been experiencing issues with floaters for several months.
A few days ago, I underwent dilation and discovered a hole in my left eye, and I have also had laser surgery.
I would like to ask a few questions:
1.
After having a hole, am I more likely to develop another one in the future?
2.
I am relatively young and not highly myopic; what other factors could cause a hole?
3.
The doctor did not specify any restrictions after my laser surgery, but I have seen some people mention avoiding heavy lifting, water exposure, or vigorous exercise.
Should I be cautious about these activities, or can I maintain my normal lifestyle?
4.
Is it possible for floaters to appear as small black spots? I can see them with my eyes open and closed, but the doctor said everything is fine during my examination.
5.
How can I differentiate between flashes caused by retinal tears or detachment and those caused by normal vitreous traction?
6.
It has been five days since my laser treatment, but I still feel a pulling sensation and occasionally experience sharp pain.
Is this normal?
Thank you for your response, Doctor.

More Info

Hello! Thank you for your questions regarding retinal issues, particularly in relation to floaters and the recent laser surgery you underwent. It's understandable to have concerns after experiencing such conditions, and I will address your queries one by one.

1. Risk of Future Retinal Holes: After having a retinal hole, there is a possibility of developing additional holes, especially if there are underlying conditions such as lattice degeneration or if the vitreous gel continues to pull on the retina. However, the risk isn't significantly higher for everyone. Regular follow-ups with your ophthalmologist are crucial to monitor your retinal health.

2. Causes of Retinal Holes: While age and high myopia are common risk factors for retinal holes, other factors can contribute as well. These include trauma to the eye, certain eye diseases, and even genetic predispositions. In younger individuals, the vitreous gel can become less cohesive and may pull away from the retina, leading to holes or tears.

3. Post-Laser Surgery Precautions: After laser surgery, it is generally advisable to avoid heavy lifting, vigorous exercise, and activities that could strain your eyes for a short period. While your doctor may not have specified strict limitations, it's wise to err on the side of caution. Engaging in normal daily activities is typically acceptable, but listen to your body and avoid anything that causes discomfort.

4. Appearance of Black Shadows: Floaters can manifest as small black spots or shadows in your vision. If you notice these consistently, it's essential to keep track of their frequency and any changes. If they increase in number or if you experience flashes of light, you should consult your ophthalmologist promptly, as these could indicate retinal issues.

5. Distinguishing Between Types of Flashes: Flashes of light can occur due to vitreous traction on the retina or from retinal tears. Generally, flashes associated with retinal tears are more persistent and may be accompanied by a sudden increase in floaters or a shadow in your peripheral vision. If you experience these symptoms, seek immediate medical attention.

6. Post-Surgery Sensations: Experiencing a pulling sensation or occasional sharp pain five days post-surgery can be normal as your eye heals. However, if the pain worsens or if you notice any significant changes in your vision, you should contact your doctor. Healing can vary from person to person, and it's essential to monitor your symptoms closely.

In summary, while some discomfort and concerns are typical after laser surgery, maintaining regular follow-ups with your ophthalmologist is vital for monitoring your retinal health. If you notice any new symptoms or changes, do not hesitate to reach out to your healthcare provider. They can provide personalized advice based on your specific situation and medical history. Remember, your vision is precious, and proactive management is key to maintaining it.

Hello, 1. Laser treatment is aimed at retinal reinforcement, not specifically for floaters (the source of flashes). 2. These all fall within the scope of floaters. 3. Astigmatism correction, like myopia, primarily involves glasses, contact lenses, laser treatments, and so on.
