Flashes, Floaters, and Sudden Vision Changes: When to Call a Retina Specialist
Our eyes act as gateways to the world around us, but what happens when unexpected flashes or floaters disrupt our vision? While slight vision changes are normal with age, certain symptoms can signal more serious underlying issues with the retina, the vital light-sensitive layer at the back of the eye. Understanding flashes and floaters and knowing when to consult a retina specialist can help safeguard your vision for years to come.
Understanding Flashes and Floaters
Floaters look like tiny clumps of gel that cast shadows on your retina, and they can appear as spots, specks, or even cobwebs drifting around. Flashes, however, show up as streaks, flickers, or sparks of light. Most of the time, flashes and floaters are linked to a condition called posterior vitreous detachment (PVD). This happens when the vitreous, the clear, gel-like substance that fills the eye, shrinks and separates from the retina, which is common after age 50. Other things that can cause flashes and floaters include eye injuries, severe nearsightedness, or even migraine auras.
When to Be Concerned About Flashes and Floaters
Flashes and floaters are normal, which can make it difficult to determine whether they indicate a bigger issue. If you experience the following symptoms, it’s important to see an eye care professional as soon as possible:
- A sudden, large increase in the number of floaters
- Frequent, bright flashes of light that do not go away
- A dark shadow, gray veil, or "curtain" moving across your field of vision, usually starting in the periphery
- Any sudden blurring or significant loss of vision
The Importance of Seeking Retinal Care
While most cases of flashes and floaters aren’t concerning, retinal exams are extremely important when it comes to certain symptoms that could indicate a retinal tear or detachment. Retinal tears are medical emergencies that require immediate treatment, as they can lead to retinal detachment. This detachment occurs when the retina pulls away from its normal position, separating the retinal cells from the blood vessels that supply the eye with oxygen and nutrients. The longer retinal detachment goes untreated, the greater the risk of permanent vision loss in the affected eye, underscoring the importance of prompt diagnosis and treatment.
