Almost everyone eventually sees floaters, and many people notice occasional flashes. Most of the time these are a normal part of the eye's aging — but new flashes or a sudden change in floaters needs a prompt dilated exam, because a small percentage signal a retinal tear that is very treatable when caught early.
The inside of the eye is filled with a clear gel called the vitreous. With age, the gel becomes more liquid and small strands clump within it; what you "see" are their shadows drifting across the retina — specks, cobwebs, or squiggles that dart away when you try to look at them. They're more common with age, in nearsighted eyes, and after cataract surgery.
Brief sparkles, streaks, or camera-flash sensations — often in your side vision, and more noticeable in the dark — happen when the vitreous gel tugs on the retina. Tugging itself is common; the question that matters is whether the tug has torn anything.
At some point — typically in one's 50s to 70s — the vitreous gel pulls away from the retina entirely. This event, called a PVD, classically announces itself with a new floater (often a ring or cobweb) and some flashes. The large majority of PVDs settle harmlessly, and the floaters fade from notice over weeks to months. But in the early weeks after a PVD begins, the risk of a retinal tear is at its highest — which is why new symptoms deserve an exam even when they're probably benign.
We dilate your pupils and examine the entire retina, including its far edges where tears most often hide, supported by retinal imaging when useful. If everything is intact — which is the most common outcome — you leave with reassurance and clear instructions on what changes to watch for. If we find a tear, we arrange urgent referral to a retina specialist, where laser treatment can usually seal it before it progresses.
Long-standing, stable floaters that have already been examined are a nuisance, not a danger. Most people's brains learn to ignore them. They don't need treatment — just an annual exam, and a prompt visit if their pattern ever suddenly changes.
