Managing Post-Injection Eye Floaters
Recently we had a question from one of our great community members regarding post-injection floaters. Most of us who get the injections have floaters lasting anywhere from a few hours to a few weeks. Many seniors have floaters even without any injections, just as part of aging.
Eye injection floaters
Most times, I will have what looks like a single, round black sequin with a small white center. It gradually shrinks so that by the next day, it will have become just a very few small specks.
Calling the doctor
Another cause of my floaters happened about 2 years ago when I had the symptoms of posterior vitreous detachment or PVD. A flicker of flashing lights in the corner of one eye, which lasted barely a second, followed by a few fuzzy threads and cobwebs in that same area.
A call to my eye doctor suggested it was probably posterior vitreous detachment, a common occurrence in old age. About one-quarter of people have some vitreous shrinkage with floaters by their 60s; that rises to about two-thirds of 80-year-olds.
To make sure this wasn’t the beginning of a retinal detachment or tear, he called me in for a check. Some symptoms of a retinal detachment are a sudden onset of floaters, or flashes of light, or even a curtain across your vision. A detached retina is a medical emergency that requires immediate treatment to prevent permanent vision loss.1
Floaters began to settle
But back to my floaters. Those threads and squiggles from the PVD have slowly settled down to just barely noticeable in my peripheral vision when I look at the sky or my computer with a light background.
A bit of floater trivia I recently discovered: The floaters we see are not the actual bits of debris, clumps of the vitreous, or even the injected medication, but the shadows which they cast on the retina.
Treatment options for post-injection floaters
Until recently, the only treatment for intrusive floaters was surgery. A vitrectomy removes the vitreous from your eye and replaces it with a sterile saline solution. But this is a procedure where the risk may outweigh the benefits and is only done in severe cases.
YAG laser vitreolysis
A newer treatment is YAG laser vitreolysis, which is still in its infancy in medical timelines. This too comes with risks that may outweigh the rewards. It also isn’t suitable for all types of floaters.
As an example, those with soft borders aren’t good candidates. Most doctors still prefer to wait until the brain will hopefully adapt to them, and we wouldn’t notice them. They do tend to settle below the field of vision.
Giving it time
I’m sorry to say there is no natural treatment available that can help make floaters dissolve, except for time. But even time isn’t perfect.
The only thing I’ve found helps after an injection is to invert the colors when reading or working on my iPad. Using white letters on a black background makes the floaters almost magically disappear.
