Vitreous Macula

Hello Doctor: I have vitreous degeneration, which is pulling on the macula and causing a tear.
During my last two follow-up visits, the vitreous continued to exert traction, and the tear has been getting larger.
The doctor mentioned that a vision of 0.9 is still good and recommended continued observation.
If one day it leads to a macular hole, is there still a possibility of blindness after surgery? Or would the vision recovery be limited, potentially dropping to 0.1 due to the hole, with little improvement post-surgery? One eye has a vision of 0.6 and has already experienced a detachment, so I thought it wouldn’t pull anymore.
However, during these last two visits, I found that the vitreous on the right side continues to pull, causing the tear to enlarge.
The other eye, with a vision of 0.9, is also under traction; it hasn't torn yet, but the hole is also getting larger.

Hello:
1.
Risk of Macular Hole
The macula is an important area of the retina responsible for central vision.
A macular hole refers to a defect in the macula that can lead to severe vision loss, distortion, and other symptoms.
In some cases, a macular hole may result in blindness.
Based on your description, the macular hole in your left eye has not yet fully developed, but it is showing a tendency to continue expanding.
This indicates that you are at risk for a macular hole.
2.
Surgical Treatment
The treatment for a macular hole is surgical intervention.
The goal of the surgery is to close the hole and promote retinal repair.
The success rate of the surgery depends on various factors, including the size and location of the hole, as well as the patient's age and overall health.
In your case, since the hole has not yet fully developed, the success rate of the surgery may be higher.
However, even if the surgery is successful, there is no guarantee that vision will fully recover.
In some instances, postoperative vision may still experience decline or distortion.
3.
Recommendations
I recommend that you follow your physician's advice and continue to closely monitor the condition of your left eye.
If you experience any of the following symptoms, you should seek medical attention immediately:
* Sudden vision loss
* Distortion of vision
* Dark spots in your central vision
If you have any questions or concerns about your condition, you should also feel free to consult your treating physician.

More Info

Understanding vitreous degeneration and its potential impact on macular health is crucial, especially for individuals experiencing symptoms like you described. Vitreous degeneration refers to the changes that occur in the vitreous humor, the gel-like substance that fills the eye. As we age, the vitreous can become less gel-like and more liquid, leading to a condition known as vitreous syneresis. This process can cause the vitreous to pull away from the retina, which may lead to complications such as retinal tears or holes, particularly in the macular region.

In your case, the ongoing vitreous traction on the macula is concerning. The macula is responsible for central vision, and any disruption in its integrity can lead to significant visual impairment. If the vitreous continues to exert traction and eventually causes a macular tear, the consequences can be serious. While your current vision of 0.9 is good, the risk of vision loss increases if a tear occurs. Surgical intervention, such as vitrectomy, may be necessary to address the issue, but it is important to understand that surgery does not guarantee a full recovery of vision. The outcome can vary significantly depending on the extent of the damage and the timing of the intervention.

If a macular hole develops, the vision may drop to 0.1 or worse, and while surgery can improve vision, the extent of recovery is often limited. Many patients experience only partial restoration of vision, and some may not regain their previous level of visual acuity. Factors such as the duration of the macular hole before surgery, the presence of other retinal conditions, and individual healing responses all play a role in the final visual outcome.

Regarding your concern about the vitreous traction on both eyes, it is essential to maintain regular follow-ups with your ophthalmologist. Continuous monitoring is crucial, as the situation can change rapidly. If you notice any new symptoms, such as an increase in floaters, flashes of light, or a shadow in your vision, you should seek immediate medical attention.

In terms of prevention and management, while there are no specific dietary changes or supplements proven to reverse vitreous degeneration, maintaining overall eye health is beneficial. A diet rich in antioxidants, omega-3 fatty acids, and vitamins such as A, C, and E can support retinal health. Regular eye exams are vital, especially for individuals with a history of vitreous degeneration or retinal issues.

In conclusion, while vitreous degeneration is a common condition, its implications for macular health can be serious. The risk of developing a macular tear or hole necessitates vigilant monitoring and timely intervention. Although surgery can help, it is essential to have realistic expectations regarding visual recovery. Always consult with your eye care professional for personalized advice and treatment options tailored to your specific situation.
