Seeing patterns in the eyes?

Hello doctor, three months ago, I started seeing dense, radiating patterns that resemble blood vessels in certain areas when my eyes are closed.
However, it is not similar to lightning.
Could this indicate some kind of pathology?

Hello: Based on your symptoms, it appears to be a phenomenon of vitreous degeneration.
The shapes can be dot-like (such as black dots, sand, bubbles, gas bubbles, or fish eggs), linear (such as black strands, cotton-like fibers, hair, spider webs, or hooks), or surface-like (such as circles, shadows, bees, or mosquitoes), and even three-dimensional (like clouds, rain, swarms of locusts, or blobs of ink).
We commonly refer to this as "floaters." The degeneration and shrinkage of the vitreous itself does not affect our visual function; however, because the vitreous is tightly connected to the retina, and adheres closely to the optic nerve head, retina, blood vessels, and peripheral serrated area, there is a possibility that during the process of vitreous shrinkage, the retina may be pulled and even torn, which could lead to retinal detachment and severely impact our visual function.
Therefore, a thorough examination is indeed necessary, especially when there is a sudden increase in floaters or flashes of light in the eye, which warrants a detailed check-up.
If the examination reveals issues with the retina, early treatment can be initiated; if the retina is found to be normal, there is no need for excessive concern, and one can gradually get used to the presence of floaters, much like tolerating the existence of gray hair.
Thank you for your inquiry.

More Info

The symptoms you're describing, particularly the appearance of radiating patterns or "blood vessel-like" lines in your vision when your eyes are closed, can be concerning and may indicate several underlying eye conditions. It's essential to understand that visual disturbances can arise from various factors, and a thorough evaluation by an eye care professional is crucial for accurate diagnosis and treatment.

One potential cause for the visual phenomenon you are experiencing could be related to the vitreous humor, the gel-like substance that fills the eye. As we age, the vitreous can undergo changes, leading to what is known as vitreous detachment. This condition can cause floaters or flashes of light, and in some cases, individuals may perceive unusual patterns or shapes when their eyes are closed. While vitreous detachment is often benign, it can sometimes lead to more serious issues, such as retinal tears or detachment, which require immediate medical attention.

Another possibility is the presence of migraine aura, which can manifest as visual disturbances, including zigzag lines or radiating patterns. These auras can occur with or without a headache and may last from a few minutes to an hour. If you have a history of migraines, this could be a plausible explanation for your symptoms.

Additionally, conditions affecting the retina, such as retinal tears or holes, could also lead to unusual visual experiences. These conditions can sometimes present with symptoms like flashes of light or the perception of patterns, particularly in low-light conditions. Given that you mentioned seeing these patterns with your eyes closed, it is essential to rule out any retinal issues, as they can lead to more severe complications if left untreated.

Moreover, the phenomenon you describe might also be related to ocular migraines or even issues with the optic nerve. In some cases, inflammation or other pathological changes in the optic nerve can lead to visual distortions.
Given the complexity of visual disturbances and the potential for serious underlying conditions, it is highly recommended that you seek a comprehensive eye examination. An eye care professional can perform various tests, including a dilated fundus examination, optical coherence tomography (OCT), and visual field testing, to assess the health of your retina and optic nerve.
In summary, while the symptoms you are experiencing could be benign, they warrant further investigation to rule out any serious conditions. Early detection and treatment are crucial in preserving vision and preventing complications. If you notice any changes in your vision, such as an increase in the frequency or intensity of these patterns, or if you experience other symptoms like flashes of light or a sudden increase in floaters, seek medical attention promptly.
