Understanding retinal health is crucial for preserving your vision. Retinal tears and detachments are serious conditions that require prompt attention. Contact a top specialist in your area through our directory to ensure your eye health.
Your retina is a thin layer of tissue at the back of the eye that functions like camera film—capturing images and sending them to your brain. Any problem with the retina can threaten your sight, making conditions like retinal tears and detachments especially serious.
Although both conditions affect the retina, they aren’t the same:
Retinal Tears
A retinal tear is a break or hole in the retina's delicate tissue. This usually happens when the vitreous, the clear gel-like substance filling your eye, shrinks with age and pulls against the retina, causing it to tear. While a small tear might initially cause minimal or subtle symptoms, it creates an opening allowing fluid to pass beneath the retina. Over time, this fluid buildup can lead to the more severe condition known as retinal detachment. Prompt diagnosis and treatment of retinal tears significantly decreases the risk of progression to detachment.
Typical symptoms of retinal tears include:
Retinal Detachments
A retinal detachment is a serious medical emergency occurring when the retina completely separates from its underlying supportive tissue at the back of the eye. This detachment cuts off the retina's essential nutrient and oxygen supply, which can quickly result in permanent damage and loss of vision if not immediately addressed. Retinal detachments often begin as retinal tears, which is why early detection and immediate treatment of a tear are essential to prevent detachment and severe vision loss.
Typical symptoms of a retinal detachment include:
Posterior Vitreous Detachment (PVD): A Common Precursor
As we age, the gel-like substance in the eye (vitreous) contracts and may pull away from the retina—a process called Posterior Vitreous Detachment (PVD). While PVD is often harmless, it can occasionally tug hard enough to create a retinal tear. This is why new floaters or flashes in your vision should never be ignored.
Retinal detachment occurs in three primary forms: rhegmatogenous, tractional, and exudative. Each type has a distinct cause and progression, but all forms require prompt evaluation and treatment to prevent permanent vision loss.
Rhegmatogenous Retinal Detachment
Rhegmatogenous retinal detachment is the most common type, accounting for approximately 90% of all detachments. It occurs due to one or more tears in the retina, allowing fluid from the vitreous cavity to seep beneath and lift the retina away from the underlying tissue. This fluid accumulation disrupts the retina's function, leading to rapid vision impairment. Aging is a primary risk factor, but other factors such as severe nearsightedness (myopia), previous cataract surgery, trauma, and certain retinal conditions (like lattice degeneration) significantly increase risk.
Key points:
Specific symptoms include:
Tractional Retinal Detachment
Tractional retinal detachment occurs when scar tissue on the surface of the retina contracts and physically pulls the retina away from its normal position. This form of detachment commonly affects individuals with diabetes who have diabetic retinopathy, as prolonged high blood sugar levels cause abnormal blood vessels and scar tissue to form on the retina. Other conditions causing tractional detachment include severe eye injuries, infections, and inflammatory diseases of the eye.
Key points:
Specific symptoms include:
Exudative Retinal Detachment
Exudative retinal detachment is less common and occurs when fluid accumulates beneath the retina without any tears or breaks. It results from conditions that cause abnormal fluid leakage or inflammation within the eye, such as age-related macular degeneration (AMD), tumors, inflammatory diseases, or vascular abnormalities like central serous retinopathy.

Specific symptoms include:
Understanding these types of retinal detachment, their unique risk factors, and distinctive symptoms allows for early detection and prompt treatment, which is critical in preserving your vision.
Both retinal tears and detachments share similar warning signs. Contact an eye doctor immediately if you experience any of the following:
Flashes of Light
Sudden, brief flashes—like sparks or “stars”—often in peripheral vision.
New or Increasing Floaters
Specks or cobweb-like strings drifting across your sight; a sudden “swarm” of floaters is especially concerning.
Blurred or Distorted Vision
Could be mild at first, then gradually worsen.
Dark Curtain or Shadow
A shadow seeming to creep from the edges inward, sometimes described as a "curtain" coming over part of your vision.
Loss of Side Vision
Peripheral vision often goes first, leaving you feeling like your visual field is closing in.
If you notice flashes, floaters, or any sudden vision changes, an urgent eye exam is critical. Our retina specialist will typically:
Perform a Dilated Eye Exam
Special drops enlarge your pupils, allowing a clear view of the retina.
Use Ultrasound Imaging
If bleeding or cloudiness obscures the retina, ultrasound can detect detachments or tears.
Conduct Optical Coherence Tomography (OCT)
Provides highly detailed cross-sectional images of the retina, showing any separation or fluid buildup.
Treating a retinal tear early often prevents a detachment. However, if the retina is already detached, more extensive treatment may be needed.
For Retinal Tears
For Retinal Detachments
If you're experiencing symptoms like flashes of light or an increase in floaters, don’t hesitate. Schedule an appointment with one of our expert eye doctors listed with Specialty Vision today to ensure your vision stays protected and healthy.
While you can’t control certain risk factors like aging or family history, there are ways to reduce your chances of severe retinal complications:
Regular Eye Exams
Especially vital if you have high myopia, a family history of retinal issues, or diabetes. Annual dilated exams help detect silent tears or early traction.
Manage Diabetes
Controlling blood sugar levels lowers the chance of diabetic retinopathy, which can lead to tractional detachments.
Protect Your Eyes
Use protective eye wear during sports or high-risk activities to prevent trauma.
Know the Symptoms
Flashes, new floaters, or any shadow creeping across your vision shouldn’t be ignored—early intervention is key.
Treating a retinal tear early often prevents a detachment. However, if the retina is already detached, more extensive treatment may be needed.
Outcomes from Retinal Tears and Detachments
When a retinal tear or detachment is addressed promptly, outcomes are generally good:
Vision recovery timelines vary. Many people notice improvements within a few weeks, though full visual stabilization can take months—especially after a vitrectomy or scleral buckle. In some cases, if the detachment was extensive or longstanding, some level of permanent vision loss may remain.
Post-Op Care
While retinal tears and detachments can happen to anyone, certain factors increase the likelihood:
Age (40+)
The vitreous gel becomes more liquid, making tears more likely.
Posterior Vitreous Detachment (PVD)
Posterior Vitreous Detachment, which typically occurs as part of the normal aging process, can also trigger retinal tears. As the vitreous gel shrinks and separates from the retina, traction on the retina may lead to small rips or holes—especially in eyes with significant myopia. Symptoms of a PVD often include new floaters or flashes of light, underscoring why seeing a retina specialist when you have sudden or more frequent flashes or floaters is so important.
Severe Nearsightedness (Myopia)
The elongated shape of a highly myopic eye stretches the retina, making it more prone to tears. Studies show people with myopia worse than -3.00D have a significantly higher risk.
Family History
A history of retinal detachment or tears in close relatives.
Previous Eye Surgery
Surgeries like cataract removal can alter the eye’s internal structures.
Eye Trauma
Injuries can lead to tears, either immediately or over time.
Diabetes/Diabetic Retinopathy
Chronic high blood sugar damages retinal blood vessels and can lead to tractional detachment.
Lattice Degeneration
Thinning of peripheral retinal tissue, especially common in myopic eyes.
Inflammatory Eye Conditions
Uveitis or other inflammation can weaken retinal attachments.
