Floaters can be really annoying. They are visible bits of the vitreous jelly at the back of the eye. Most of us have small ones which are most visible when looking at the sky or a painted wall i.e. a blank background. But some have them so severely they can appear like a cobweb which blurs vision or a dense ring, wiggly line or an fly near your eye. They aren’t usually significant, but if they are accompanied by flashing lights in peripheral vision it is worth having a retinal membrane check. The floaters may just go away. They can sometimes be treated with a YAG laser but this isn’t always possible or effective. A vitrectomy operation is a more invasive option for which the risks and benefits must be carefully considered.
But wouldn’t it be great if there was an eyedrop which dissolved the floaters? There is some evidence that Microplasmin injections do dissolve the vitreous jelly, but it hasn’t been shown to reduce floaters, nor is it available as an eyedrop ... yet! So at the moment all we can do is cross our fingers & hope they go away, or have a YAG laser or vitrectomy treatment.
