Understanding Flashes and Floaters

Have you ever noticed tiny spots, lines, or flashes in your vision? These are known as flashes and floaters, and while they are common and usually harmless, it’s essential to understand when they might signal a more serious issue.

At EK Eyewear, we’re here to provide clarity on these symptoms and guide you on what steps to take if you experience them.

 

What Are Flashes and Floaters?

Flashes: These occur when the jelly-like substance inside your eye (the vitreous) shrinks slightly and tugs on the retina, the light-sensitive layer at the back of your eye. This tugging can cause brief flashes of light at the edge of your vision. It’s important to note that flashes caused by vitreous traction are different from visual disturbances associated with migraines.

Floaters: These appear as tiny spots, lines, or cobweb-like shapes, often noticeable when looking at a plain background such as a white wall or blue sky. They can be semi-transparent or dark and appear to float in your vision. Floaters are usually harmless and caused by tiny clumps of cells in the vitreous casting shadows on the retina. Some people are born with floaters and most floaters develop as you get older, when the gel in your eye naturally shrinks. Occasionally, a sudden increase in floaters may be a sign of problems inside the eye. 

 

Common Causes of Flashes and Floaters

The most common cause of floaters, particularly in people over 45 years old, is a condition called posterior vitreous detachment (PVD). This occurs when the vitreous gel inside the eye peels away from the retina, leading to the appearance of floaters in your vision. While this can be disturbing and sudden, it’s generally not harmful.

However, if PVD causes the vitreous to tug too hard on the retina, it can create a small tear. This tear can lead to retinal detachment, a serious condition requiring immediate medical attention. This is when your retina pulls away from the back of your eye. This may lead to a blank spot or shadow in your vision that does not go away.

When Should You Be Concerned?

Most flashes and floaters are benign, but certain symptoms should prompt you to seek advice from your optician or healthcare provider immediately:

  • A sudden increase in floaters, especially if accompanied by flashes.
  • Flashes of light in your vision, even when your eyes are closed or in the dark.
  • A dark shadow or ‘curtain’ moving across your vision.
  • A significant change in your vision.

If you experience any of these symptoms, it’s crucial to seek prompt attention. You can contact us at EK Eyewear or make an appointment through our website. If you cannot reach us, go to your local A&E or eye casualty department right away.

An ophthalmologist or an optometrist will use eye drops and a special microscope to look inside your eye to check if your retina is damaged.

 

What Happens if the Retina Tears?

The retina is essential for vision, receiving images and sending them to your brain. A tear in the retina can lead to detachment, resulting in partial or total vision loss.

Quick intervention is key and there is a fast-track referral pathway by the opticians to eye casualty that can take care of this condition in a very quick space of time:

  • Laser Treatment: If caught early, a retinal tear can often be treated with a laser, which can prevent the retina from detaching.
  • Surgery: If the retina has already detached, surgery is usually required to reattach it. Prompt treatment is critical to preserve vision as much as possible.

 

Monitoring Changes in Symptoms

Stay vigilant about changes in your vision. If you’ve previously consulted an optometrist but notice worsening flashes, floaters, a black shadow, or any new visual disturbances, seek emergency care immediately.
