Is this floaters?


Hello, Dr.
Tsai.
Recently, I have been experiencing flashes of white circular spots in my peripheral vision, occurring approximately every twenty minutes.
It's not directly in front of me, but rather in my left rear field of vision.
I remember being startled the first time it happened, thinking something was behind my shoulder.
After a few occurrences, I confirmed that it was a cluster of white light spots.
Is this a type of floaters, or could it be due to eye fatigue? I have allergic rhinitis, which often leads to excessive eye discharge and itching in the corners of my eyes.
Additionally, I have large eyes, and sometimes debris gets blown into them.
I haven't felt any significant discomfort lately, but the persistent appearance of these white light spots has left me puzzled about what they could be.

Furthermore, I previously visited a doctor for red and swollen eyes, and they prescribed me allergy-specific eye drops.
Recently, I purchased another allergy-specific eye drop from the pharmacy, but it feels very cooling—so much so that I need to rest for about three minutes before I can open my eyes comfortably.
If it's too cooling, could that be harmful to my eyes? For my allergic eyes, do I need to regularly use eye drops for maintenance? If so, how should I choose them? I would appreciate your guidance on this.
Thank you very much.
3Q.
Ling.

What has been mentioned above is indeed a manifestation of floaters.
If there is a history of ocular trauma or high myopia, it is best to undergo a dilated retinal examination, which will alleviate concerns regarding the presence of flashes of light.
Antihistamine eye drops, if not too strong or containing steroid components, can be used regularly in the morning and evening; however, it is important to monitor intraocular pressure and corneal health.
Excessive cooling is often caused by the components of the eye drops, so reducing the frequency of use or switching medications may be advisable.
It is recommended to visit an outpatient clinic for evaluation and follow the physician's advice thereafter.

More Info


Understanding eye floaters, or "myodesopsia," is essential for anyone experiencing these symptoms. Floaters are small spots or lines that appear in your field of vision, often described as cobwebs or specks that drift as you move your eyes. They are typically caused by changes in the vitreous humor, the gel-like substance that fills the eye, which can become more liquid and form clumps as we age. This process is often benign, especially in individuals without other eye conditions.

In your case, the white circular spots you are seeing in your peripheral vision could indeed be a form of floaters. The fact that they appear intermittently and are not accompanied by other troubling symptoms such as flashes of light or significant vision loss is reassuring. However, it is crucial to monitor these symptoms, especially if their frequency or intensity increases. If you experience a sudden increase in floaters or flashes of light, or if you notice a shadow or curtain effect in your vision, you should seek immediate medical attention, as these could be signs of retinal detachment.

Your mention of having allergic rhinitis and experiencing itchy eyes, along with the use of allergy eye drops, suggests that your eye discomfort may also be related to environmental factors. Allergies can lead to inflammation and irritation of the eyes, which might exacerbate the perception of floaters or even cause additional visual disturbances. The use of allergy-specific eye drops can help alleviate symptoms, but it’s important to ensure that these drops are appropriate for your condition. If the drops feel excessively cold or uncomfortable, it may be worth discussing with your healthcare provider to find a formulation that is more suitable for your needs.

Regarding the management of your allergic conjunctivitis, regular use of prescribed eye drops can be beneficial in controlling symptoms and preventing flare-ups. It’s essential to follow your doctor’s instructions regarding the frequency and dosage of these medications. If you find that over-the-counter options are too harsh or uncomfortable, consider consulting with an ophthalmologist who can recommend alternatives that may be less irritating.

In terms of eye care, maintaining good habits can also help reduce discomfort. Here are some additional tips:
1. Limit Screen Time: Prolonged use of screens can lead to eye strain, which may exacerbate floaters and other visual disturbances. Follow the 20-20-20 rule: every 20 minutes, take a 20-second break and look at something 20 feet away.

2. Stay Hydrated: Proper hydration can help maintain the health of your eyes and reduce dryness, which may contribute to discomfort.

3. Protect Your Eyes: If you are prone to allergies, consider wearing sunglasses outdoors to shield your eyes from wind and allergens.

4. Regular Eye Exams: Regular check-ups with an eye care professional are crucial, especially if you have a history of eye issues or if you notice changes in your vision.

5. Manage Allergies: Continue to manage your allergic rhinitis with appropriate medications and avoid known allergens when possible.

In summary, while the appearance of floaters can be concerning, they are often a normal part of aging and not necessarily indicative of a serious problem. However, given your history of allergies and eye discomfort, it’s essential to maintain regular communication with your eye care provider to ensure that your symptoms are managed effectively. If you have any further questions or if your symptoms change, don’t hesitate to reach out for professional advice.
