the Progression of Floaters: When to Seek Help - Ophthalmology

It seems that my floaters are gradually worsening?


Hello, Doctor.
I discovered I had floaters about two months ago.
There are about two or three in my right eye and five or six in my left eye (all are semi-transparent gray).
I had an examination two months ago and went for another check-up last week; both doctors said my retina is normal and that I should just have regular follow-ups.
However, I’ve noticed that the floaters seem to be gradually worsening.
It’s not that I suddenly see many more, but rather that they are slowly increasing (for example, two originally unconnected points seem to slowly connect with a semi-transparent line over a few weeks; I’m not sure if they were always there or if it’s worsening).
I would like to ask: 1.
How should I handle this situation? Is this a worsening of the floaters? 2.
Currently, I do not see any flashes or lightning, but there was a time when a bright spot appeared in my right eye (without any particularly glaring light), just one spot that flashed briefly, leaving a blue afterimage that disappeared after about three to five seconds, located right in my line of sight.
This has occurred about three times in the past two weeks.
Does this indicate retinal detachment? Should I return for a follow-up?

More Info


Floaters, or "flying flies," are a common visual phenomenon, particularly among individuals with myopia (nearsightedness) or those who are aging. They are typically caused by changes in the vitreous gel that fills the eye, which can lead to the formation of small clumps or strands that cast shadows on the retina, resulting in the perception of floaters. Given your recent experiences and concerns, let's address your questions in detail.

1. Management of Floaters: The gradual increase in the number of floaters you are experiencing can be concerning, especially if they seem to be connecting or forming new shapes. However, it's important to note that floaters can fluctuate in visibility and quantity over time. Since your previous examinations have indicated that your retina is normal, this is a positive sign. Regular monitoring is essential, and you should continue to follow up with your eye care provider as recommended. If the floaters become significantly bothersome or if you notice a sudden increase in their number, it would be prudent to seek further evaluation. In some cases, if floaters are particularly disruptive to vision, a procedure called vitrectomy may be considered, although this is typically reserved for severe cases due to the associated risks.

2. Flashes of Light: The occurrence of brief flashes of light or bright spots in your vision, especially if they are accompanied by a blue afterimage, can be indicative of vitreous traction on the retina. While these flashes are not uncommon, they can sometimes signal a more serious condition, such as retinal detachment, particularly if they are new or have changed in character. Given that you have experienced these flashes multiple times over the past two weeks, it is advisable to return to your eye doctor for a thorough examination. They may perform a dilated fundus examination to assess the retina more comprehensively and ensure that there are no signs of retinal tears or detachment.

In summary, while floaters are often benign, the combination of increasing floaters and the occurrence of flashes warrants careful monitoring. Your eye health is paramount, and any new symptoms or changes in your vision should be promptly evaluated by a qualified eye care professional. Regular check-ups will help ensure that any potential issues are caught early, allowing for timely intervention if necessary.
Additionally, managing anxiety related to these visual changes is important. Many individuals find it helpful to engage in relaxation techniques, such as mindfulness or deep breathing exercises, to alleviate stress. Understanding that floaters are a common experience can also help reduce anxiety. However, always prioritize your health and do not hesitate to seek medical advice when you have concerns about your vision.
