Blackfly syndrome and some eye issues?


Doctor, I didn't do much at first; my eyes were just dry, and after using the eye drops, I noticed black spots and lines that weren't there before...
Is it just a coincidence that they appeared? Recently, sometimes when I look at the floor, I see a small yellow patch that appears.
Is it an illusion? It happens very occasionally, suddenly, and I don't see it often, but I see a small yellow spot on the floor, and then it disappears...
Should I go to the hospital for some tests? Should I just tell them I need a fundus examination?

Hello: Based on your description, it seems that your issue may be related to floaters.
A thorough fundus examination should suffice.
Wishing you peace and happiness.

It sounds like you are experiencing some concerning visual disturbances, including the appearance of black spots and lines, as well as occasional yellow patches on the floor. These symptoms can be quite unsettling, and it's important to understand what might be happening with your eyes.

Firstly, the black spots and lines you are seeing could be related to a condition known as "floaters." Floaters are tiny clumps of gel or cells inside the vitreous, the clear gel-like substance that fills the eye. As we age, the vitreous can shrink and pull away from the retina, causing these floaters to become more noticeable, especially in bright light or when looking at a plain background. While floaters are usually harmless, a sudden increase in their number or the appearance of new floaters, especially if accompanied by flashes of light or a shadow in your peripheral vision, can indicate a more serious issue, such as a retinal tear or detachment. Therefore, if you notice any significant changes in your vision, it is crucial to seek an eye examination promptly.

Regarding the occasional yellow patches you see on the floor, this could be a form of visual phenomenon known as a "visual aura" or a transient visual disturbance. These can occur for various reasons, including migraine-related visual disturbances, which can happen even without a headache. Sometimes, these visual auras can manifest as bright spots, zigzag patterns, or even temporary blind spots. However, if these yellow patches are frequent or concerning, it is advisable to discuss them with your eye care professional.

When you visit the eye doctor, it is essential to communicate all your symptoms clearly. You should mention the following:
1. The appearance of black spots and lines, including when they occur and any changes in their frequency or intensity.

2. The occasional yellow patches on the floor, including how often they happen and any associated symptoms (like headaches or other visual changes).

3. Any other symptoms you may have experienced, such as dry eyes, headaches, or changes in your overall vision.

The eye doctor will likely perform a comprehensive eye examination, which may include:
- Visual acuity tests to assess how well you see at various distances.

- Dilated eye examination to get a better view of the retina and vitreous, allowing the doctor to check for any abnormalities.

- Visual field tests to evaluate your peripheral vision and check for any blind spots.

- Ocular coherence tomography (OCT), if necessary, to get detailed images of the retina and assess for any structural issues.

In summary, while some visual disturbances can be benign, it is always better to err on the side of caution. Given your symptoms, it is advisable to schedule an appointment with an eye care professional for a thorough examination. Early detection and intervention can help address any potential issues before they become more serious. Your eye health is vital, and understanding the nature of your symptoms is the first step toward ensuring your vision remains clear and healthy.
