Seeing dark spots?

Hello, doctor.
I have myopia in my left eye of -6.75 and -5.25 in my right eye, along with floaters.

1.
Recently, I've been seeing small black spots when looking at things; sometimes they appear as a dot and other times as a small blot, but they are always very small.
I would like to know if this is also considered floaters.
Typically, I see transparent floaters that only appear in bright areas, but these black spots appear even in dim lighting.
2.
When I do jumping jacks or when I first wake up in the morning and my eyes are still adjusting, I suddenly see something that looks like lightning.
However, when I close my eyes, I don't see anything.
This occurs only for a brief moment when my eyes are open.
What could this be?
3.
Six months ago, during an eye examination, the doctor mentioned that my retina is quite thin.
Is this a common condition for all myopic individuals? How can I prevent it from becoming thinner?

Hello:
1.
Regarding the small black objects you described, this may be a condition known as floaters.
Floaters are typically caused by changes in the gel-like substance within the vitreous humor of the eye, which creates shadows or spots that you see in your field of vision.
They can appear in both bright and dim lighting conditions.
If you notice a significant change in these phenomena or if they cause discomfort, it is advisable to see an ophthalmologist for an evaluation as soon as possible.
2.
Seeing lightning-like flashes when you open and close your eyes or just after waking up may be due to structural changes within the vitreous body that cause these flashes.
However, flashes can also be a sign of potential retinal issues, so it is recommended that you seek an eye examination promptly for further assessment.
3.
Regarding your thin retina, it is important to note that each individual's eye structure is unique, and not all myopic individuals will have a thin retina.
A thin retina may increase the risk of retinal detachment.
It is advisable to have regular eye examinations and maintain good eye care to ensure stable myopia and prevent further thinning of the retina.

Hello! Thank you for your questions regarding your eye health, particularly concerning floaters and retinal issues. Let's break down your concerns one by one.

1. Black Spots and Floaters: The black spots you are seeing could indeed be a variation of floaters. Floaters are typically small specks or strands that drift through your field of vision, often more noticeable against a bright background. They are usually caused by changes in the vitreous gel that fills the eye, which can become more liquid and allow tiny fibers to clump together, casting shadows on the retina. The fact that you are seeing these black spots in dim lighting is noteworthy. While floaters are common, especially in individuals with myopia (nearsightedness), any sudden increase in floaters or changes in their appearance should be evaluated by an eye care professional. This is particularly important because it could indicate a more serious condition, such as a retinal tear or detachment.

2. Seeing Lightning-Like Flashes: The phenomenon of seeing flashes of light, often described as "lightning," can be related to a few different factors. These flashes occur when the vitreous gel pulls on the retina, which can happen during activities that involve rapid eye movement, such as jumping or sudden head movements. This is known as "photopsia." If these flashes are new or have increased in frequency, it is crucial to consult with an eye doctor. They may perform a dilated eye exam to check for any signs of retinal issues, especially since you have a history of thin retina.

3. Thin Retina and Myopia: It is common for individuals with high myopia to have a thinner retina. The elongation of the eyeball in myopia can lead to changes in the retina, making it more susceptible to thinning and potential complications. Not every myopic individual will experience retinal thinning, but it is a risk factor. To help prevent further thinning, it is essential to manage your myopia effectively. This can include regular eye exams, wearing prescribed corrective lenses, and possibly discussing options like orthokeratology or refractive surgery with your eye care provider. Additionally, protecting your eyes from excessive strain, such as taking regular breaks from screens and ensuring proper lighting while reading or working, can also be beneficial.

In summary, while floaters and flashes can be common occurrences, any changes in your vision, especially with your history of myopia and retinal thinning, warrant a thorough examination by an eye care professional. They can provide a detailed assessment and recommend appropriate management strategies tailored to your specific needs. Regular monitoring and proactive care are key to maintaining your eye health. If you have any further questions or concerns, don’t hesitate to reach out to your eye doctor. Your vision is invaluable, and taking care of it is paramount.
