Floaters and Retinal Issues

1.
I have myopia in both eyes of over 500 degrees and have experienced floaters (only one or two) for a long time.
However, in the past few weeks, the floaters have increased to 7-8 black spots.
When I look at the sky at a certain height, several black spots turn into a short black line.
Initially, it was only in one eye, but now both eyes are affected.
Is this normal? Does this increase indicate a serious condition?
2.
When I look at the sky and move my eyes, I see a fleeting black line at the outer corner of my right eye that disappears quickly.
Is this also a floater?
3.
When I close my eyes in a dark place or cover my eyes, I see many small white dots moving.
What could that be?
4.
I would like to ask what it feels like to see flashes of light or lightning with closed eyes.
Can you describe it? I'm not sure if I have experienced this, and a few weeks ago, I had a dilated eye exam, and the doctor said my retina looks good with no holes detected.
5.
Does the term "floaters with flashes" mean that when I see floaters, flashes of light may also appear?

When it comes to understanding floaters and potential retinal issues, it's important to recognize that these symptoms can be common, but they can also indicate underlying problems that require medical attention. Let's address your questions one by one.

1. Increased Floaters: The appearance of new floaters, especially if they have increased from one or two to seven or eight, can be concerning. Floaters are typically caused by changes in the vitreous gel of the eye, which can occur with age or due to other factors. While having a few floaters is common, a sudden increase in their number or a change in their appearance (like turning into lines) can sometimes indicate a more serious condition, such as retinal tears or detachment. Given your history of myopia (nearsightedness), which increases the risk of retinal issues, it is advisable to seek an eye examination from an ophthalmologist to rule out any serious conditions.

2. Transient Black Lines: The fleeting black line you see when moving your right eye could also be related to floaters or possibly a phenomenon known as "visual snow." However, if this occurs frequently or is accompanied by other symptoms, it would be wise to consult with an eye care professional. They can perform a thorough examination to determine the cause.

3. Seeing White Spots in Darkness: The small white dots you see when your eyes are closed or covered are likely due to a phenomenon called "phosphene." Phosphenes are the perception of light without light actually entering the eye, often caused by pressure on the retina or the optic nerve. This is generally harmless, but if you notice any changes in your vision or if these spots become more pronounced, it’s worth discussing with your doctor.

4. Seeing Flashes or Lightning: When you close your eyes and see flashes or lightning-like effects, this could be related to the same mechanisms that cause phosphenes. These sensations can occur due to pressure on the retina or as a result of the vitreous gel pulling on the retina. If these flashes are frequent or accompanied by other visual disturbances, it is important to seek medical advice, as they can sometimes indicate retinal issues.

5. Floaters with Flashes: The combination of seeing floaters and flashes can be significant. It often indicates that the vitreous gel is pulling away from the retina, which can lead to retinal tears or detachment. This combination should be taken seriously, and you should consult an ophthalmologist as soon as possible for a comprehensive eye exam.

In summary, while floaters and occasional flashes can be normal, significant changes in your visual symptoms warrant immediate attention. Given your myopia and the recent changes you've experienced, it is crucial to have a thorough examination to ensure that there are no serious underlying conditions. Regular eye check-ups are essential, especially if you notice any new symptoms or changes in your vision. Always prioritize your eye health and seek professional advice when in doubt.
