Eye Floaters & Flashes

What causes floaters?

Floaters are considered normal as we age and experience vision changes. Tiny strands of vitreous (the gel-like fluid that fills the eye) stick together, casting shadows on the retina (the light-sensitive layer of tissue at the back of the eye).

Most commonly, they are pretty harmless natural particles inside the eye. 70% of people experience floaters at some time.

What are eye flashes?

Like eye floaters, flashes develop in the vitreous humor. As we age, the collagen in the body breaks down more quickly, causing the gel of the vitreous humor to shrink and pull away from the retina, creating momentary flashes of light. They can appear as bright spots, lightning-like streaks, or sudden sparkles.

They may occur infrequently or intermittently over some time. However, it’s important to note that if you experience persistent or recurrent flashes of light or if they become more frequent or intense, it may be a sign of a more serious condition. You should contact us immediately or seek immediate medical attention.

Some people experience visual disturbances, including flashes of light, as part of a migraine aura, and these flashes could accompany a migraine.

What causes flashes? 

Flashes occur when the vitreous (the gel-like fluid inside the eye) fails to separate cleanly from the retina and then tugs, creating friction from portions of the retina. 

Eye floater risk factors

Eye floaters can occur in people of all ages, certain factors can increase the risk.

These include:

• 55+ years of age
• Severe nearsightedness
• Migraine sufferers
• Eye injuries
• Type 2 diabetes
• Torn retina and those diagnosed with diabetic retinopathy

How do you get rid of eye floaters? 

While eye floaters may be frustrating for individuals who frequently observe them, time is generally considered the safest course of action in most cases. Floaters tend to move away from your direct line of sight over time, making them less noticeable.

In some cases, Vitreolysis, a non-invasive, pain-free procedure, might be recommended to eliminate floaters and their visual disturbances. This treatment involves the application of nanosecond pulses of retinal laser light to severe vitreous strands and evaporates/vaporizes the opacities.

When a sudden increase of floaters significantly affects your field of vision, it could indicate retinal detachment and retinal tears. A procedure known as vitrectomy may be considered. This eye surgery involves creating incisions to remove the gel-like vitreous inside the eye, which is then replaced with a synthetic solution resembling the vitreous.

When should you see a doctor for floaters or flashes?

When floaters and flashes first appear, it is essential to have an eye exam to ensure a serious eye illness does not cause them. You should contact an eye specialist immediately if you notice:

• Sudden onset of new floaters or an increase in floaters
• Flashes of light suddenly occur in the same eye as the floaters
• Darkness suddenly appears on the sides of your vision (a sensation of fixed shadow, or “closing curtain”)

These painless symptoms could be signs of a detachment or torn retina, a sight-threatening condition that requires immediate attention. In the case of a detached retina (when the retina pulls away from the back of the eye), prompt evaluation from an eye doctor within the first 24-48 hours is crucial to maintaining or recovering your full visual potential.
