Retinal issues


Hello Dr.
Chang: I previously underwent a dilated fundus examination, and the doctor mentioned signs of retinal degeneration, stating that this phenomenon is quite common.
I then went to Chang Gung Memorial Hospital to see a retinal specialist, who said everything was normal (I am approximately -7.00 diopters nearsighted).
I was advised to monitor my vision.
Could it be that the first doctor confused vitreous degeneration with retinal degeneration? (I have floaters.) Additionally, if there is retinal degeneration, what is the usual management? Is it necessary to pursue active treatment, or is observation sufficient depending on the situation? Will it affect my vision? Currently, I have no symptoms of flashes or shadows.
Should I consider another examination?

Dear netizens; since you have already consulted two ophthalmologists and both found no issues, try not to worry too much.
Generally, patients with high myopia often experience peripheral retinal degeneration and vitreous degeneration.
It is possible that you are experiencing physiological degeneration related to typical high myopia, which is why the doctors mentioned that this situation is quite common and did not recommend any treatment.
Both physicians are correct, as retinal degeneration often accompanies vitreous degeneration, and not every case requires immediate intervention.
Some may only need to be monitored with regular check-ups every six months or annually.
The decision on whether and how to treat should be made by a specialist.
I recommend that you follow your doctor's advice, pay attention to your vision status, and have regular dilated eye examinations.
Dr.

Hello, thank you for your question regarding retinal issues, particularly concerning retinal degeneration and treatment options. It’s understandable to feel concerned about your eye health, especially when dealing with conditions like myopia and floaters.

Firstly, it’s important to clarify the distinction between vitreous degeneration and retinal degeneration. Vitreous degeneration, often associated with aging or high myopia, involves changes in the gel-like substance (vitreous humor) that fills the eye. This can lead to symptoms such as floaters, which are small specks or strands that drift through your field of vision. On the other hand, retinal degeneration refers to changes in the retina, the light-sensitive layer at the back of the eye, which can lead to more serious conditions, including vision loss.

In your case, it seems that the first physician may have been referring to vitreous degeneration rather than retinal degeneration. This is a common occurrence, especially in individuals with high myopia, and it typically does not pose a significant risk to vision unless it leads to complications such as retinal tears or detachment. The second opinion you received, which indicated that everything was normal, is reassuring. It suggests that there are no immediate concerns regarding your retina.

Regarding the management of retinal degeneration, it largely depends on the specific type and severity of the degeneration. In many cases, especially if there are no symptoms like flashes of light or new floaters, a watchful waiting approach is taken. Regular monitoring through eye exams is essential to ensure that any changes are detected early. If degeneration progresses or if there are signs of complications, more active treatment may be necessary, which could include laser therapy or surgical interventions.

You mentioned that you currently have no symptoms such as flashes or dark shadows, which is a positive sign. The absence of these symptoms typically indicates that there is no acute issue with the retina at this time. However, it’s always wise to stay vigilant and maintain regular check-ups with your eye care professional, especially given your history of high myopia and floaters.

In terms of lifestyle modifications, there are several strategies you can adopt to support your eye health. These include:
1. Regular Eye Exams: Continue to have your eyes checked regularly, especially if you notice any changes in your vision.

2. Protective Eyewear: If you are exposed to bright lights or screens for extended periods, consider wearing protective eyewear to reduce strain and potential damage.

3. Healthy Diet: A diet rich in antioxidants, omega-3 fatty acids, and vitamins C and E can support overall eye health. Foods like leafy greens, fish, nuts, and fruits are beneficial.

4. Limit Screen Time: Reducing the amount of time spent on screens can help alleviate eye strain and discomfort.

5. Manage Underlying Conditions: If you have any systemic conditions, such as diabetes or hypertension, managing these effectively can also help protect your vision.

In conclusion, while vitreous degeneration is common and often benign, it’s crucial to remain proactive about your eye health. Regular check-ups and being aware of any changes in your vision are key. If you have any lingering doubts or if your symptoms change, don’t hesitate to seek further evaluation from an eye care specialist. Your vision is invaluable, and staying informed is the best way to protect it.
