Eye floaters


Hello doctor, I recently noticed that when I look up slightly or lower my neck after looking up, my vision shows a round, blurry, and slightly dark hollow circle.
As I lower my neck further, the hollow circle enlarges, and when I raise my neck, it shrinks.
If I don't look up excessively, my vision remains normal without any abnormalities.
I would like to ask the doctor what this might be.
I feel like I didn't have this symptom before, and I just discovered it recently.
I'm worried that it might be due to pressure on my optic nerve or something similar...

Hello, anxious college student: Looking up excessively can lead to ocular pressure, which may cause such phenomena.
It is advisable to avoid such movements.
This should not be a significant issue.

Hello! It sounds like you're experiencing some concerning visual symptoms, particularly with the appearance of circular, blurry, and somewhat dark hollow shapes in your vision when looking upward or adjusting your neck position. Let’s break down what you might be experiencing and address your concerns.

Firstly, the phenomenon you are describing could be related to a few different factors, but it is important to note that visual disturbances like floaters are quite common, especially as we age. Floaters are tiny clumps of gel or cells inside the vitreous, the clear gel-like substance that fills the eye. When light passes through the vitreous, these clumps cast shadows on the retina, which you perceive as floaters. They can appear as spots, threads, or, in your case, hollow circles.
The fact that these floaters seem to change size based on your neck position could suggest that they are indeed related to the vitreous gel's movement within your eye. When you tilt your head or look in certain directions, the vitreous may shift slightly, causing the floaters to appear more prominent or change shape. This is generally a benign condition, especially if you have had recent eye examinations that did not reveal any serious issues.

However, your concern about potential pressure on the optic nerve or other serious conditions is understandable. While floaters are usually harmless, there are instances where they can be associated with more serious conditions, such as retinal tears or detachments, particularly if they are accompanied by flashes of light or a sudden increase in the number of floaters. If you notice any of these additional symptoms, it is crucial to seek immediate medical attention.

In your case, since you mentioned that this is a new symptom and you are feeling anxious about it, I recommend scheduling a follow-up appointment with your eye care provider. They can perform a comprehensive eye exam, including a dilated fundus examination, to ensure that your retina and optic nerve are healthy. It’s also important to communicate any changes in your vision, as this can help your doctor assess your situation more accurately.

Additionally, it’s worth noting that stress and anxiety can exacerbate the perception of visual disturbances. If you find yourself overly worried about your symptoms, consider discussing your concerns with a healthcare professional who can provide reassurance and support.

In summary, while the symptoms you are experiencing may be related to benign floaters, it is always best to err on the side of caution and consult with an eye care professional for a thorough evaluation. Regular eye exams are essential for maintaining eye health, especially if you notice any changes in your vision. Remember, early detection and intervention are key in addressing any potential issues. Take care of your eyes, and don’t hesitate to seek help when needed!
