What Are Flashes and Floaters?

Flashes and floaters are visual disturbances that many people experience at some point in their lives.

  • Floaters appear as small dots, strands, or cobweb-like shapes drifting across your field of vision, especially when looking at a bright background. They occur when tiny clumps form in the vitreous gel inside the eye.
  • Flashes are brief bursts or streaks of light, often in the peripheral vision. These happen when the vitreous gel pulls on or tugs at the retina.

While flashes and floaters are often harmless and related to the natural ageing process, they can sometimes indicate serious conditions such as a retinal tear or retinal detachment, which can lead to permanent vision loss if untreated.

Why Am I Seeing Flashes or Floaters?

Several factors can increase the likelihood of developing flashes and floaters:

  • Age: Most commonly seen in people over 50.
  • Nearsightedness (myopia): Increases the likelihood of vitreous changes.
  • Eye trauma
  • Diabetes
  • Cataract surgery

In some cases, flashes and floaters are caused by posterior vitreous detachment (PVD), where the vitreous gel pulls away from the retina. Although usually harmless, PVD can occasionally lead to a retinal tear or detachment, which requires urgent treatment.

When to Seek Immediate Attention

At Edgbaston Eye Clinic, we emphasise the importance of seeking prompt medical evaluation if you notice:

  • A sudden onset of flashes
  • An increase in floaters
  • A dark shadow or curtain over your vision

These symptoms could indicate a retinal detachment, a medical emergency requiring immediate intervention to prevent vision loss.

Diagnosis and Monitoring

Our clinic in Birmingham specialises in the diagnosis and management of flashes and floaters. We use advanced imaging technologies such as:

  • Optos Ultrawide Field Imaging
  • Optical Coherence Tomography (OCT)

These tools capture detailed images of the retina and optic nerve, allowing us to detect retinal abnormalities early and ensure appropriate care.

Treatment Options

In most cases, flashes and floaters are benign and do not require treatment.

However, if a retinal tear or detachment is detected, treatment may include:

  • Laser therapy
  • Vitrectomy surgery

Our team works closely with leading retinal specialists to provide timely and effective treatment when necessary.

Regular Eye Check-Ups

We recommend regular eye examinations, especially if you have risk factors such as diabetes or myopia, to monitor retinal health and prevent complications.

Flashes and floaters can be distressing, but early evaluation and expert care can protect your vision. At Edgbaston Eye Clinic, we provide advanced solutions and peace of mind to ensure your eyes remain healthy.
