Floaters and Eye Health: When to Seek Help

Floaters are already an eye problem; I would like to inquire about it?

Hello, Doctor Gao.
I have two questions I would like to ask.
Recently, I have noticed that when I deliberately focus on a certain spot and then move my head or turn my eyes, I occasionally see a small gray or black dot float by, or sometimes a wave-like pattern that is a bit difficult to describe.
I would like to know if this is normal.
About six months ago, I visited an ophthalmologist for eye pressure and other tests, and the doctor said everything was healthy, except for slightly dry eyes, for which I was advised to use eye drops.
However, I did not specifically mention this symptom to the doctor.
I feel like I have experienced this before, but I only noticed it when I was paying special attention.
I am concerned that it might be related to floaters.
Is treatment necessary, or do you have any suggestions for improvement or prevention of worsening? I also noticed that some blood vessels are visible in the white part of my eyes.
Is this really not a concern? The previous doctor said there was no problem, but I would like to consult you further.
Thank you.

Hello, based on your symptoms, it seems you are experiencing floaters.
If there have been no changes over a long period, it is likely harmless.
However, if there are changes such as a sudden increase in floaters or seeing flashes of light, you should undergo a dilated eye examination.
Floaters are a normal part of aging and there is no way to prevent or treat them.
The conjunctiva covering the white part of the eye contains blood vessels, and irritation, allergies, or excessive eye strain can cause these vessels to become congested, leading to visible red streaks.
If there is a growth in the eye, it is important to avoid ultraviolet light and wear sunglasses when outdoors.
If you are not experiencing any discomfort, it should not be a concern.
The ophthalmology department at Puzi Hospital in Taiwan is open Monday, Tuesday, Thursday, and Friday mornings from 8:00 AM to 12:00 PM, and Wednesday afternoons from 2:00 PM to 4:30 PM.
Please note that online responses are for reference only, and it is advisable to seek medical attention at a healthcare facility if necessary.
I hope to have the opportunity to assist you.

Hello! Thank you for reaching out with your questions about floaters and overall eye health. It’s understandable to be concerned about any changes in your vision, especially when it comes to symptoms like floaters or seeing blood vessels in the sclera (the white part of your eye). Let’s break down your concerns and provide some clarity.

Understanding Floaters
Floaters are small specks or strands that drift through your field of vision. They are often more noticeable when looking at a plain background, such as a blue sky or a white wall. These floaters are typically caused by changes in the vitreous humor, the gel-like substance that fills the eye. As we age, the vitreous can become more liquid and may pull away from the retina, leading to the perception of floaters.
From your description, it sounds like you are experiencing typical floaters, especially since you mentioned that they occur when you move your head or eyes. This is a common experience and is usually not a cause for concern. However, if you notice a sudden increase in floaters, flashes of light, or a shadow in your peripheral vision, it is crucial to seek immediate medical attention, as these could be signs of retinal detachment.

When to Seek Help
Since you had a comprehensive eye exam six months ago and your eye pressure and overall health were deemed good, it’s likely that what you’re experiencing is benign. However, if the floaters become more frequent or bothersome, or if you experience any other visual disturbances, it would be wise to consult with your eye care professional again. They can perform a thorough examination to ensure that there are no underlying issues.

Eye Dryness and Treatment
You mentioned experiencing dry eyes and using eye drops. Dry eyes can exacerbate visual disturbances, including the perception of floaters. It’s essential to manage dry eye symptoms effectively. Here are some tips:
1. Stay Hydrated: Drink plenty of water throughout the day.

2. Use Artificial Tears: Regularly use preservative-free artificial tears to keep your eyes moist.

3. Take Breaks: Follow the 20-20-20 rule when using screens: every 20 minutes, look at something 20 feet away for 20 seconds.

4. Consider Humidifiers: Using a humidifier in your home can help maintain moisture in the air, especially in dry environments.

Blood Vessels in the Sclera
Seeing blood vessels in the sclera is generally normal and not a cause for concern. The sclera is a fibrous tissue that provides structure to the eye, and it contains blood vessels that supply nutrients to the eye. If your previous eye doctor indicated that everything was fine, it’s likely that this is just a normal anatomical feature. However, if you notice any changes in the appearance of your sclera, such as increased redness or swelling, it would be prudent to have it checked.

Conclusion
In summary, what you are experiencing with floaters seems to be typical, especially given your recent eye health assessment. Maintaining good eye care practices, managing dryness, and monitoring any changes in your vision will help you maintain optimal eye health. If you have any further concerns or if symptoms change, don’t hesitate to reach out to your eye care provider for a follow-up. Regular eye exams are essential, especially as you age or if you have a family history of eye conditions. Take care of your eyes, and thank you for your thoughtful questions!
