the Occurrence of Black Spots in Your Vision - Ophthalmology

More Info

---

The phenomenon you are experiencing, where you see small black dots or spots in your vision when your eyes are closed, can be concerning, but it is not uncommon. These visual disturbances can be attributed to several factors, and understanding them can help alleviate some of your worries.

Firstly, what you are describing may be related to a common condition known as "visual snow" or "phosphene." Phosphenes are the perception of light without light actually entering the eye, often experienced when pressure is applied to the eyes or when they are closed. This can manifest as spots, flashes, or patterns of light. The small black dots you see could be a result of the way your brain processes visual information in the absence of external stimuli.

Another possibility is that these dots are related to the vitreous humor in your eyes. The vitreous is a gel-like substance that fills the eye and can sometimes become less transparent with age or due to other factors. This can lead to the formation of floaters, which are small particles that can cast shadows on the retina, creating the appearance of spots or dots in your vision. However, floaters are typically more noticeable when looking at a bright background, such as a clear sky or a white wall, rather than when your eyes are closed.

Additionally, the presence of these dots could be linked to a phenomenon known as "entoptic phenomena," where you perceive visual effects that originate from within your own body, particularly from the structures of your eyes. When your eyes are closed, the pressure from your eyelids can stimulate the retina, leading to the perception of these dots.

It's important to note that while these occurrences can be benign, they can also be indicative of underlying issues, especially if they are accompanied by other symptoms such as flashes of light, sudden changes in vision, or a significant increase in the number of floaters. Conditions such as retinal detachment or other retinal disorders can present with similar symptoms and require prompt medical attention.

Given that you only notice these dots when your eyes are closed and they are not present during the day or when your eyes are open, it is less likely to be a serious condition. However, it is always advisable to consult with an eye care professional for a comprehensive eye examination. They can assess your symptoms in detail, perform necessary tests, and rule out any potential issues that may require treatment.

In summary, while the small black dots you see when your eyes are closed may be benign and related to normal visual phenomena, it is essential to monitor your symptoms. If you notice any changes in your vision or if the dots become more frequent or bothersome, seek professional advice. Regular eye check-ups are crucial for maintaining eye health and addressing any concerns you may have.
