We help to maintain vision through regular VisionSafe Eye Checks


Are you over 40 and haven’t had a comprehensive eye check done in the last year? A VisionSafe Eye Check can help you know if flashes and floaters are anything to be concerned about


Flashes and floaters

Symptoms of flashes of lights or floating dots in the vision can be indicative of a separation of the gel-like fluid (vitreous) in the eye from the retina (posterior vitreous detachment). Rarely, these symptoms can be associated with retinal detachment in which the light-detecting layer at the back of the eye (the retina) comes away from the eye leading to loss of vision.

Get a consultation for flashes and floaters in St Albans

If you suspect you have flashes or floaters, book an eye consultation that includes:

  • Clinical History
  • Vision measurements
  • Eye examination (dilated examination of the peripheral retinal to exclude retinal tears or retinal detachment)
  • Retinal imaging tests (colour fundus photography and optical coherence tomography imaging)

An urgent assessment of the problem is warranted to help identify people with retinal detachment needing treatment. All patients with new floaters and flashing lights should have an eye examination and appropriate tests within 24 hours of the onset of symptoms wherever possible to help exclude a diagnosis of retinal detachment or retinal tear. If the problem turns out to be a separation of the gel (posterior vitreous detachment) with no evidence of retinal tears or retinal detachment then in most cases the symptoms should settle over time.
