Is this considered floaters?
Hello doctor, I have noticed that whenever I turn my head to the left or blink my eyes, I see a "C"-shaped shadow in the lower left area of my left eye.
Sometimes, I also see a "C"-shaped bright white light, but it disappears quickly.
It may reappear when I turn left or blink again, and it occurs intermittently.
I have had my retina examined, and it is normal.

More Info
The symptoms you are describing, particularly the appearance of "C"-shaped shadows or flashes of light in your left eye when you turn your head or blink, could indeed be related to floaters or other vitreous changes in the eye. Floaters are small, shadowy shapes that can appear in your field of vision, often described as spots, threads, or cobwebs. They are typically caused by changes in the vitreous gel that fills the eye, which can become more liquid and less gel-like as we age. This process can lead to the formation of floaters, which are more noticeable against bright backgrounds.
In your case, the intermittent nature of the symptoms, along with the specific shapes you are seeing, suggests that these could be related to the vitreous gel pulling away from the retina, a condition known as posterior vitreous detachment (PVD). While PVD is common and often harmless, it can sometimes lead to more serious conditions, such as retinal tears or detachment, especially if accompanied by flashes of light or a sudden increase in floaters.
The fact that your retinal examination was normal is reassuring, but it is essential to continue monitoring your symptoms. If you notice any sudden changes, such as a significant increase in floaters, the appearance of new flashes of light, or a shadow or curtain effect in your peripheral vision, you should seek immediate medical attention. These could be signs of retinal issues that require prompt treatment.
Additionally, the presence of white flashes could indicate that the vitreous is tugging on the retina, which can happen during PVD. These flashes are often brief and can occur in bursts, typically fading quickly. However, if they persist or worsen, it is crucial to consult with an eye care professional.
In summary, while your symptoms may be related to floaters or changes in the vitreous, it is essential to remain vigilant and report any new or worsening symptoms to your eye doctor. Regular eye examinations are vital, especially if you have a history of eye conditions or if you are experiencing new visual disturbances. Your eye health is paramount, and staying proactive about any changes will help ensure that any potential issues are addressed promptly.
