Black Spots in Vision: What High Myopia Patients Should Know - Ophthalmology

Share to:

There are shadows in the corners of the vision in the eyes?


Hello, doctor! I am a patient with high myopia, with my right eye at -7.20 and my left eye at -9.20.
I do not see any signs of floaters when I look up, down, left, or right.
However, when I focus on the edge of my vision to the right, I see a "fixed" blurry black dot.
When I try to concentrate on the dot, it gradually fades until I can no longer see it.
When I look again, the dot is still in the same position and will fade away again.
Additionally, the dot only moves when I move my neck, while my eyes remain completely still.
What could be happening? Is there a problem with my retina? I am really anxious about this.
2.
My left eye has a history of floaters, and during my last visit to the ophthalmologist, it was diagnosed as benign floaters.
Recently, I have noticed that when I close my eyes in sunlight, I can see the shadows of floaters more clearly.
Has my condition worsened? Could it turn into malignant floaters? I am really worried.
With the recent surge in COVID-19 cases, I am hesitant to visit a crowded hospital for an eye exam, as I am concerned about bringing illness home to my family.
Therefore, I can only seek advice here.
Thank you, doctor, for patiently addressing my concerns.

Hello, Xin Min: It is recommended that you visit a clinic for an examination to ensure peace of mind, and try to avoid areas with severe outbreaks.
Without an examination, it is impossible to determine if there is an issue.
If you truly cannot go, you should carefully monitor any changes in your symptoms, and if there is any impact on your vision, seek medical attention immediately.
Online responses can only serve as a reference; if necessary, you should still seek care at a medical facility.
I hope to have the opportunity to serve you.
Best regards, Gao Pi-Lin.

Understanding black spots in vision, especially for high myopia patients, is crucial for maintaining eye health and addressing potential concerns. Based on your description, it appears that you are experiencing some visual phenomena that can be quite alarming, particularly given your history of high myopia.

1. Black Spots and Visual Phenomena: The black spots you see, especially when you focus on them, could be related to a phenomenon known as "floaters." Floaters are tiny clumps of gel or cells inside the vitreous, the clear gel-like substance that fills the eye. They can cast shadows on the retina, which is why you might see them as black spots, especially in bright light or when looking at a plain background. The fact that these spots seem to fade when you focus on them is typical of floaters, as they are often more noticeable when your eyes are moving or when you are looking at a bright surface.

2. High Myopia and Retinal Concerns: High myopia (or severe nearsightedness) increases the risk of retinal problems, including retinal tears or detachments. The presence of persistent floaters, especially if accompanied by flashes of light or a sudden increase in the number of floaters, should prompt a visit to an eye care professional. While your current symptoms may not indicate an immediate retinal issue, it is essential to monitor any changes in your vision closely.

3. Changes in Vision: Your concern about the left eye and the visibility of floaters in bright light is also valid. While benign floaters are common, any significant changes in their appearance or an increase in their number can be a cause for concern. It is essential to differentiate between benign and potentially harmful floaters. If you notice any new symptoms, such as flashes of light, a shadow or curtain over your vision, or a sudden increase in floaters, you should seek medical attention promptly.

4. COVID-19 Considerations: Given the current COVID-19 situation, it is understandable to be cautious about visiting healthcare facilities. However, many eye care providers have implemented safety measures to minimize the risk of virus transmission. If you are experiencing significant changes in your vision or have concerns about your eye health, it is advisable to contact your eye doctor. They may offer telehealth consultations or have specific protocols in place to ensure patient safety.

5. Regular Eye Exams: Regular eye examinations are crucial for high myopia patients. These exams can help detect any changes in the retina or other parts of the eye that may require intervention. If you have not had a comprehensive eye exam recently, consider scheduling one as soon as it is safe to do so.

6. Managing Anxiety: It is natural to feel anxious about changes in your vision, especially with a history of high myopia. However, staying informed and proactive about your eye health can help alleviate some of that anxiety. Keeping a journal of any changes in your vision and discussing them with your eye care provider can also be beneficial.

In summary, while the black spots you are experiencing may be related to benign floaters, it is essential to remain vigilant, especially given your high myopia. Regular check-ups with an eye care professional are vital for monitoring your eye health and addressing any concerns promptly. If you notice any new symptoms or significant changes in your vision, do not hesitate to seek medical advice, even during the pandemic. Your eye health is paramount, and taking proactive steps can help ensure your vision remains stable.
