Eye Floaters and Flashes: Warning Signs and Treatment

Understanding Eye Floaters and Flashes

As we age, many people begin noticing small specks or cobweb-like shadows that float through their field of vision. Known as eye floaters, these common visual disturbances can be alarming at first. However, in most cases they are a natural part of the aging process and not a cause for concern.

What Are Eye Floaters?

Eye floaters appear when small pieces of material inside the eye break loose and drift into the jelly-like vitreous humour, or vitreous, that fills the back of the eye. These bits of debris cast shadows on the retina, leading to small specks, dots, circles, lines or cobweb-like images that seem to float through the field of vision.

The most common eye floaters are caused by remnants of collagen, which helps maintain the shape of the vitreous. As we age, the vitreous starts to break down and liquefy. Bits of the deteriorating collagen get caught in the more liquid center of the vitreous, causing shadows and images that we perceive as eye floaters.

What Causes Eye Floaters?

In addition to collagen from a deteriorating vitreous, other common causes of eye floaters include:

• Bleeding from a ruptured blood vessel
• Clumps of cells
• Microscopic fibers
• Minerals floating in the vitreous

Eye floaters tend to affect far-sighted people more due to faster deterioration of the vitreous. They also become more common with:

• Increasing age
• Nearsightedness
• Eye injuries or trauma
• Inflammation
• Eye infections
• Cataract surgery
• Certain medications like tamoxifen and amiodarone

When Floaters and Flashes Signal a Problem

While eye floaters are usually part of the normal aging process, they can sometimes indicate an underlying problem that requires medical attention.

See your eye doctor or retina specialist right away if you experience a sudden increase in floaters, especially if you also see flashing lights or other vision changes. This could signal a retinal detachment or tear - a serious condition that can lead to blindness unless treated promptly.

Signs of Concern

Be on the watch for these red flag eye floater and flashing light symptoms:

• New shower of eye floaters - Numerous tiny dots suddenly appearing in your vision requires urgent evaluation to rule out a retinal tear or detachment
• Flashing lights like lightning bolts or strobe lights - These often accompany retinal detachments
• Floaters appearing like a cobweb or veil over your vision - This type of floater needs emergency care
• Partial vision loss - Can indicate a detached or torn retina, which can rapidly lead to blindness if not treated quickly

Even a single new floater can be serious if you also have flashing lights or vision changes.

Underlying Eye Conditions

In addition to retinal holes or detachments, eye floaters coupled with flashes can signal other sight-threatening eye disorders like:

• Bleeding disorders like diabetes
• Blocked blood vessels
• Eye inflammation
• Eye infections
• Eye tumors
• Complications after cataract surgery

Any new onset of eye floaters or light flashes warrants a complete dilated eye exam to pinpoint the cause. Prompt treatment improves outcomes for vision-robbing conditions like retinal detachment.

When Floater Symptoms Persist

It's common to have some floaters come and go over time. But you should return for follow up care if:

• Your eye floaters don't go away or decrease after a few months
• The number of floaters increases
• Your floaters constantly distract your vision throughout the day
• Flashes don't go away after a few weeks

While serious problems are less likely in milder, chronic cases it's wise to rule out subtle retinal abnormalities.

Dealing with Annoying Floaters

Bothersome eye floaters that persist can impair your quality of life. Things like reading, computer work and driving can prove challenging when annoying spots clutter your field of vision.

Unfortunately, the brain never completely adapts to chronic floaters. However, you can minimize impacts by:

• Using bright light to constrict your pupils
• Trying yellow tinted glasses to see floaters less
• Focusing behind or through the floater
• Blinking repeatedly to settle the floater out of central vision
• Taking breaks when floaters frustrate task concentration

Treating Eye Floaters

Currently there is no permanent cure for common eye floaters beyond vitrectomy surgery. However newer laser treatments show promise for drastically reducing floater visibility.

Vitrectomy removes the vitreous through tiny incisions and replaces it with a clear fluid. By eliminating the internal debris, shadows disappear. However, vitrectomy for floaters alone remains controversial given its risks, which include retinal detachment, bleeding, infection and accelerated cataracts.

Several laser techniques now provide safer options by zapping floaters without touching the retina. Consult a specialist to see if these newer technologies might help reduce bothersome symptoms.

Recognizing Warning Signs

Most eye floaters and flashes are harmless results of aging. Still, their sudden onset or association with impaired vision requires urgent evaluation. Seek emergency care for symptoms like:

• Sudden shower of new specks
• Flashing lights
• Veil or curtain over your vision
• Partial vision loss

Quick treatment of retinal damage improves outcomes. So don't dismiss new onset floaters or flashes until getting cleared by an ophthalmologist.
