**Flashes and Floaters: What’s Normal and When to Act Fast**
Most of us have noticed them at some point: small specks, threads or cobweb-like shapes drifting across our vision, most visible against a bright sky or a white wall. Floaters are extremely common, and in the majority of cases they are completely harmless. But there are times when floaters, particularly when accompanied by flashes of light, warrant urgent attention. At Brian D Suttie Opticians in Chesham, we want every patient to know the difference.
Floaters are tiny clumps of collagen within the vitreous, the clear gel that fills the inside of the eye. As we age, the vitreous naturally becomes more liquid and can shrink away from the retina, a process called posterior vitreous detachment. This is usually harmless, though it often produces a sudden increase in floaters and brief flashes of light as the gel tugs on the retina.
However, in a small number of cases, this tugging can tear the retina, and a retinal tear can progress to a retinal detachment, a sight-threatening emergency. Warning signs include a sudden shower of new floaters, persistent flashing lights, a dark curtain or shadow spreading across your vision, or a sudden drop in sight. If you experience any of these, seek urgent eye care the same day.
Our independent practice is exceptionally well equipped to assess flashes and floaters. UltraWide-field imaging and OCT scanning allow our optometrists to examine the retina in fine detail, checking carefully for tears or areas of weakness and providing genuine reassurance when all is well.
If you have noticed new floaters or flashes, don’t ignore them and don’t panic either. Contact Brian D Suttie Opticians in Chesham and our experienced team will make sure your eyes are examined promptly and thoroughly. When it comes to your retina, it is always better to check.
