Shadows in Your Sight: When Eye Floaters and Flashes Signal an Eye Care Emergency

Seeing a small speck or strand drift across your vision can be distracting, but it is not always a cause for alarm. Eye floaters are common, particularly as the eyes change with age. However, a sudden appearance of new floaters or flashes of light can sometimes point to a more serious problem involving the retina. At Eye Care Associates of Princeton, we encourage patients in Princeton to know when these changes require prompt attention.

What Are Eye Floaters and Flashes?

Floaters may look like dots, strings, cobwebs, or small shadows that move across your field of vision. They often result from changes in the vitreous, the gel-like substance inside the eye. Small fibers or clumps within the vitreous can cast shadows on the retina, creating the appearance of floaters.

Flashes are brief streaks, flickers, or bursts of light. They can occur when the vitreous pulls or rubs against the retina. While these symptoms can occur with normal age-related changes, new or rapidly increasing floaters and flashes should be evaluated by an eye doctor.

When Floaters and Flashes Become an Emergency

A sudden change in your vision can indicate a retinal tear or retinal detachment. Retinal detachment occurs when the retina separates from its normal position at the back of the eye. Because this can lead to permanent vision loss, immediate evaluation is important.

Seek emergency eye care if you experience:

•          A sudden increase in the number of floaters

•          New or frequent flashes of light

•          A dark shadow in your peripheral vision

•          A curtain-like effect moving across your vision

•          Sudden blurred or reduced vision

These symptoms should not be ignored or put off until your next routine eye exam.

Why Prompt Eye Care Matters

Retinal problems can develop quickly, and they are not always painful. That means a person may feel completely fine while experiencing a potentially serious change inside the eye.

When patients in Princeton notice sudden floaters, flashes, or missing areas of vision, prompt examination allows us to evaluate the retina and determine what may be causing the symptoms. A dilated eye exam is commonly used to look for retinal tears or detachment. Additional retinal imaging may also help provide a detailed view of the back of the eye.

At Eye Care Associates of Princeton, our diagnostic capabilities include OCT and Optos retinal imaging, technologies that help us examine the retina and other important structures of the eye in detail.

Do Not Wait for Symptoms to Improve on Their Own

Not every floater or flash means there is an emergency, but sudden changes deserve attention. The safest approach is to have your eyes evaluated so we can determine whether the symptoms are related to normal vitreous changes or something that requires urgent care.
