Floaters and flashes are among the most common visual symptoms people experience, especially as they age. According to the American Academy of Ophthalmology, most people develop eye floaters as they get older, typically beginning in their 50s and becoming more common by age 70. While many cases are harmless, sudden or persistent changes can sometimes indicate a retinal tear, detachment, or other serious eye conditions that require prompt attention. In most cases, floaters and flashes are a normal part of aging, but getting a professional eye exam is the best way to confirm your eyes are healthy and rule out any serious problems.
At Everett & Hurite Eyecare Specialists, we provide advanced eye floaters treatment and treatment for flashes of light in peripheral vision across Pittsburgh, Butler, Monroeville, Greensburg, Cranberry, and surrounding areas. With a dedicated team of ophthalmologists and retina specialists, we use the latest diagnostic and treatment technology to preserve and restore vision.
In this article, you’ll learn how eye doctors identify and manage floaters and flashes, the conditions linked to them, and why regular eye exams are key to maintaining healthy vision.
The Difference Between Floaters and Flashes
What Are Eye Floaters?
Eye floaters are small, shadowy shapes that drift through your field of vision. They may appear as dots, squiggly lines, cobwebs, or tiny specks that move when you move your eyes. Floaters occur when the vitreous gel, a clear substance that fills the inside of the eye, begins to shrink and form tiny clumps. These clumps cast shadows on the retina, the light-sensitive layer at the back of your eye, creating the illusion of floating spots.
Most floaters are age-related and benign. However, a sudden increase in their number or changes in their shape could point to a retinal tear or detachment, which requires immediate medical evaluation.
What Are Eye Flashes?
Flashes appear as brief bursts or streaks of light in your peripheral vision. They happen when the vitreous gel tugs or pulls on the retina, stimulating the light receptors. This can feel like seeing lightning flicker, even in a dark room. Persistent or new flashes may signal a retinal problem, especially if they occur with new floaters or blurred vision.
How Eye Doctors Diagnose Floaters and Flashes
Diagnosing the cause of floaters and flashes requires careful evaluation of the eye’s internal structures. At Everett & Hurite, our ophthalmologists and retina specialists use advanced tools to detect even subtle retinal changes.
Comprehensive Eye Exam
A complete dilated eye examination is the first step. Eye drops are used to widen the pupils, allowing the doctor to examine the retina, vitreous, and optic nerve in detail. This exam helps determine whether the symptoms are harmless or due to an underlying retinal tear, detachment, or bleeding.
Ophthalmoscopy and Retinal Imaging
Using specialized lenses and bright light, ophthalmologists inspect the retina’s surface for tears or inflammation. In some cases, optical coherence tomography (OCT) or ultrasound imaging may be used to capture cross-sectional images of the retina and vitreous. These tools provide precise information about retinal thickness, blood vessel health, and vitreous movement.
Identifying Underlying Causes
Through these diagnostic tests, the doctor determines whether floaters and flashes stem from:
- Posterior vitreous detachment (PVD): A natural separation of the vitreous gel from the retina.
- Retinal tear or detachment: A serious emergency that can lead to vision loss if untreated.
- Bleeding in the vitreous: Often linked to diabetic retinopathy or trauma.
- Inflammation (uveitis): May occur due to autoimmune or infectious conditions.
Common Eye Conditions Linked to Floaters and Flashes
Floaters and flashes can appear independently or as early signs of various retinal and ocular disorders. Recognizing these links helps doctors address potential risks before they cause lasting vision damage.
Posterior Vitreous Detachment (PVD)
This is the most common cause of floaters, especially in adults over 50. As the vitreous gel naturally shrinks, it detaches from the retina. While PVD itself isn’t dangerous, it can sometimes lead to small retinal tears.
Retinal Tear or Detachment
A retinal tear occurs when the vitreous pulls too hard on the retina, creating an opening that can allow fluid to leak underneath. If untreated, this can progress to retinal detachment, a sight-threatening emergency. Symptoms include a sudden shower of floaters, bright flashes, or a shadow or curtain across your vision.
Diabetic Retinopathy
In people with diabetes, damaged blood vessels can leak into the vitreous, causing new floaters or blurry vision. Detecting these symptoms early through regular eye exams is crucial for preventing vision loss.
Inflammatory and Traumatic Causes
Eye inflammation (uveitis) and trauma can also trigger floaters and flashes. In these cases, the symptoms are often accompanied by redness, pain, or sensitivity to light.
Treatment Options for Floaters and Flashes
Treatment depends on the underlying cause, symptom severity, and how much they affect your vision. At Everett & Hurite, we offer a range of evidence-based eye floaters treatments designed to protect and enhance visual health.
Observation and Monitoring
In most cases, benign floaters gradually become less noticeable as the brain adapts. Your doctor may recommend monitoring them with periodic eye exams to ensure no new retinal problems develop.
Therapies and Procedures
Therapies such as laser can lead to retinal detachment and are not recommended. In more severe or persistent cases, a vitrectomy may be performed. During this procedure, the vitreous gel, along with the clumped material causing floaters, is removed and replaced with a clear solution. This surgery can dramatically improve vision, but like all procedures, it carries potential risks such as infection or retinal detachment.
Treating Flashes Caused by Retinal Tears
If flashes are caused by a retinal tear or detachment, treatment may involve laser repair or cryotherapy (freezing therapy) to seal the tear and prevent further detachment. In more advanced cases, retinal surgery may be required to restore the retina to its proper position.
Why Regular Eye Exams Are Crucial
Even if your symptoms seem minor, regular eye exams play a vital role in protecting your vision. Many serious retinal conditions develop silently, showing no symptoms until advanced stages. Annual exams allow your doctor to:
- Detect changes in the vitreous or retina early.
- Prevent retinal detachment through timely intervention.
- Monitor chronic conditions like diabetes that affect the eyes.
At Everett & Hurite, our specialists emphasize proactive care, identifying problems early to ensure the best outcomes for every patient.
