What Is Retinal Detachment
The retina is a thin layer of light-sensitive tissue that lines the back wall of your eye. It works much like the film in a camera. When light enters your eye, the retina converts that light into electrical signals. These signals travel through the optic nerve to your brain, where they become the images you see every day. Without a healthy, properly attached retina, clear vision is not possible.
Retinal detachment occurs when the retina pulls away or separates from its normal position along the back of the eye. When this happens, the retina is cut off from the layer of blood vessels that provides it with oxygen and nourishment. The longer the retina stays detached, the greater the risk of lasting vision loss in the affected eye.
Retinal detachment is a medical emergency. It does not improve on its own, and prompt treatment is essential to protect your sight. If you notice sudden changes in your vision, contact Washington Eye Institute right away or seek emergency eye care. Early action gives you the best chance of preserving your vision.
Many people experience warning signs before a full detachment develops. These symptoms can appear suddenly and may include a sharp increase in floaters, which are small dark spots or squiggly lines that drift across your field of vision. You may also notice sudden flashes of light in one or both eyes, similar to a camera flash or lightning bolt.
Another common warning sign is the appearance of a shadow or dark curtain that seems to move across part of your visual field. Some people describe it as a gray veil closing in from the side, top, or bottom of their vision. Any of these symptoms calls for immediate evaluation by an eye care professional.
Who Should Seek Urgent Eye Care
While retinal detachment can happen to anyone, certain factors raise the likelihood. People who are very nearsighted, a condition known as high myopia, have longer-than-average eyes. This stretches the retina thinner and makes it more vulnerable to tears and detachment. A family history of retinal detachment also increases your risk, so it is helpful to share this information with your care team.
Previous eye surgeries, including cataract removal, can change the internal structure of the eye and raise the risk of detachment months or even years later. If you have had eye surgery in the past, your care team at Washington Eye Institute may recommend periodic retinal examinations.
Retinal detachment becomes more common as people age, especially for adults in their fifties and beyond. The vitreous, a gel-like substance that fills the inside of the eye, naturally shrinks and becomes more liquid over time. As it pulls away from the retina during a process called posterior vitreous detachment, it can tug on the retina and create a tear that leads to detachment.
Diabetic retinopathy affects 7.7 million Americans and is the leading cause of blindness among working-age adults (National Eye Institute, 2023). People living with diabetes are at higher risk of a specific form of retinal detachment caused by scar tissue growth on the retinal surface. Serious eye injuries and certain inflammatory conditions can also contribute to detachment.
You should seek care immediately if you experience a sudden shower of new floaters, flashes of light in your peripheral vision, or a shadow or curtain effect over any part of your visual field. Do not wait to see if symptoms go away on their own. Retinal detachment does not heal without treatment, and delays can lead to more extensive vision loss.
Washington Eye Institute has locations in Greenbelt, Rockville, and Cumberland. If you experience any of these symptoms, contact the office nearest to you right away. If symptoms appear outside of regular office hours, go to your nearest emergency room and let them know you are concerned about a possible retinal detachment.
How Retinal Detachment Develops
In many cases, retinal detachment begins with a small tear or hole in the retina. As the vitreous gel inside the eye shrinks with age, it can pull on the retina at points where the two are firmly attached. If the pulling force is strong enough, it creates a break in the retinal tissue. Fluid from inside the eye can then seep through the break and collect beneath the retina, gradually lifting it away from the supportive tissue underneath.
Not every retinal tear leads to a detachment. Some tears remain stable, especially when detected early. Your care team can monitor small tears and may recommend preventive laser treatment or cryotherapy, a freezing technique, to seal a tear before fluid has a chance to get underneath the retina.
In people with diabetes or other conditions that affect blood flow in the eye, abnormal blood vessels can grow on the surface of the retina. These fragile vessels may bleed and form scar tissue. Over time, the scar tissue contracts and pulls on the retina, causing it to tent up and separate from the back wall of the eye. This process can happen slowly, giving your care team time to intervene if it is caught during routine examinations.
In less common situations, fluid can build up beneath the retina even though there is no tear or break present. This happens when blood vessels beneath the retina leak fluid due to inflammation, injury, or vascular abnormalities. Conditions such as severe eye inflammation or certain tumors can push fluid under the retina and cause it to lift away. Identifying the underlying cause is essential for selecting the right treatment approach.
The retina depends on a constant supply of oxygen and nutrients from the tissue beneath it. When it separates, the retinal cells begin to weaken. The central part of the retina, called the macula, is responsible for sharp, detailed vision. If the detachment spreads to involve the macula, the odds of recovering fine central vision decrease significantly. This is why early detection and prompt surgical repair are so important.
Types of Retinal Detachment
This is the most common type of retinal detachment. The word rhegmatogenous comes from a Greek term meaning to break. It occurs when a tear, hole, or break in the retina allows liquid vitreous to flow through and accumulate between the retina and the underlying tissue. The fluid separates the retina and prevents it from functioning properly.
Rhegmatogenous detachments often begin in the outer edges of the retina, where the tissue is thinnest. If treated quickly, before the detachment reaches the central macula, the chances of preserving good vision are strong. This type of detachment is most frequently seen in older adults, people with high myopia, and individuals who have had previous eye surgery.
Tractional detachment happens when scar tissue on the surface of the retina contracts and physically pulls the retina away from the back of the eye. Unlike rhegmatogenous detachment, there is no tear involved. Instead, the mechanical force of the scar tissue causes the separation. This type is most commonly associated with advanced diabetic eye disease, though it can also result from other conditions that cause scarring inside the eye.
Tractional detachments tend to develop more gradually than other types. Regular dilated eye examinations are critical for people at risk, because early detection allows your care team to treat the underlying condition and potentially prevent the detachment from progressing.
Exudative detachment, sometimes called serous detachment, occurs when fluid leaks beneath the retina without any tear or mechanical pulling involved. The fluid comes from inflamed or damaged blood vessels or other tissue beneath the retina. Causes include inflammatory disorders affecting the eye, certain infections, and vascular abnormalities.
Treatment for exudative detachment focuses on addressing the underlying condition that is causing the fluid leakage. Once the source of fluid is controlled, the retina may gradually settle back into its proper position. Your care team will determine the best approach based on the specific cause identified during your evaluation.
What to Expect During Evaluation and Treatment
When you arrive at Washington Eye Institute with symptoms of a possible retinal detachment, your care team will perform a thorough dilated eye examination. Special eye drops will widen your pupils so the retina can be viewed clearly. Your care team will use specialized instruments to look at the entire retina, checking for tears, holes, areas of detachment, and any related conditions.
Additional imaging tests may be used to get a detailed picture of the retina's structure. Optical coherence tomography, known as OCT, creates cross-sectional images of the retina that reveal fluid pockets and subtle areas of separation. Ultrasound imaging may also be used, especially if blood or other material inside the eye makes it difficult to see the retina directly.
Vitrectomy is one of the most commonly used surgical procedures for repairing retinal detachment. During this procedure, your surgeon makes tiny openings in the white part of the eye and removes the vitreous gel. This allows direct access to the retina so the surgeon can remove scar tissue, close retinal tears with laser or cryotherapy, and gently guide the retina back into position.
Once the retina is flat against the back wall of the eye, a gas bubble or silicone oil is placed inside the eye to hold the retina in place while it heals. If a gas bubble is used, it will gradually dissolve on its own over days or weeks. Silicone oil may require a second, smaller procedure for removal once healing is complete.
A scleral buckle involves placing a small band of silicone material around the outside of the eye. This band gently pushes the wall of the eye inward toward the detached retina, helping the retina reattach. The buckle is typically left in place and is not visible from the outside. It does not usually cause discomfort once healing is complete.
Scleral buckling may be used on its own or combined with vitrectomy, depending on the location and severity of the detachment. Your surgeon will discuss which approach is best suited for your specific situation.
Pneumatic retinopexy is a less invasive option that may be appropriate for certain types of retinal detachment, particularly when the tear is located in the upper portion of the retina. During this procedure, your surgeon injects a small gas bubble directly into the eye. The bubble floats upward and presses against the area of the retinal tear, pushing the retina back into place.
Laser treatment or cryotherapy is then used to seal the tear. You will be asked to maintain a specific head position for several days following the procedure so the gas bubble stays positioned over the tear while it heals. Your care team will provide clear instructions on positioning and follow-up visits.
Recovery times vary depending on the type of surgery performed and the extent of the detachment. Most patients can expect some discomfort, redness, and swelling in the days following surgery. Your care team will prescribe eye drops to prevent infection and reduce inflammation. You will also receive instructions about activity restrictions, including limitations on bending, lifting, and vigorous exercise during the healing period.
If a gas bubble was placed in your eye, you will need to avoid air travel until the bubble has fully dissolved. Changes in air pressure during flight can cause the bubble to expand, which may increase pressure inside the eye. Your care team will let you know when it is safe to fly again.
Your Journey Through Diagnosis and Recovery
The moment you notice warning signs such as sudden floaters, light flashes, or a shadow across your vision, your priority should be getting to an eye care professional as quickly as possible. Contact Washington Eye Institute at the Greenbelt, Rockville, or Cumberland location nearest to you. If it is after hours, go to your nearest emergency room. Let the medical team know that you are experiencing possible retinal detachment symptoms so they can prioritize your evaluation.
Your care team will explain the recommended procedure, answer your questions, and walk you through each step. Most retinal detachment surgeries are performed on the same day or within a day or two of diagnosis. The urgency depends on whether the macula is still attached. If the macula remains in place, faster treatment is especially important to preserve your central vision.
You will receive anesthesia to keep you comfortable during the procedure. Many retinal surgeries are performed under local anesthesia with sedation, meaning you will be awake but should not feel pain. Your surgeon will let you know what type of anesthesia is planned for your situation.
Vision recovery is a gradual process. It is common for vision to be blurry or fluctuating in the weeks following surgery, especially if a gas bubble is present. As the bubble shrinks and dissolves, your vision will begin to clear. Full visual recovery can take several months, and the final outcome depends on factors such as how long the retina was detached and whether the macula was involved.
Your care team at Washington Eye Institute will schedule regular follow-up visits to monitor your healing, check eye pressure, and evaluate the retina's position. These appointments are very important and should not be skipped, even if your vision seems to be improving well.
After experiencing a retinal detachment in one eye, there is an increased chance of detachment in the other eye. Your care team may recommend periodic examinations of both eyes going forward. Maintaining regular dilated eye examinations is one of the most valuable steps you can take to protect your vision for the long term.
If you have underlying conditions such as diabetes or high myopia, managing those conditions carefully also helps reduce the risk of future retinal problems. Your care team can work with you and your primary care provider to develop a plan that supports your overall eye health.
Frequently Asked Questions About Retinal Detachment
Retinal detachment is a medical emergency, and you should seek care as soon as possible after noticing symptoms such as sudden floaters, flashes of light, or a shadow across your vision. In many cases, treatment within the first day or two can make a meaningful difference in visual outcomes. If the central macula has not yet detached, urgent surgery may preserve your sharpest central vision. Even if symptoms seem mild, it is best to be evaluated right away rather than taking a wait-and-see approach.
Visual recovery varies from person to person. Many patients experience significant improvement in their vision after successful surgical repair, especially when the detachment is treated before it involves the central macula. However, some patients may notice that their vision does not fully return to what it was before the detachment. Factors that affect recovery include the duration and extent of the detachment, the type of surgery performed, and the overall health of the eye. Your care team will give you a realistic picture of what to expect based on your specific circumstances.
Small, occasional floaters are very common and are usually harmless. They are caused by tiny clumps of cells or gel within the vitreous that cast shadows on the retina. However, a sudden increase in the number of floaters, especially when accompanied by flashing lights or a shadow in your peripheral vision, can be a sign that the retina has torn or begun to detach. The key difference is the sudden onset and severity of symptoms. Any abrupt change in the number or pattern of floaters warrants a prompt eye examination.
During the recovery period, your care team will likely ask you to avoid strenuous physical activities, heavy lifting, and bending at the waist. If a gas bubble was placed in your eye, you will need to maintain certain head positions as directed and avoid air travel until the bubble has dissolved. Swimming and submerging your head in water should also be avoided until your surgeon clears you. Most patients are able to gradually return to their normal activities over a period of several weeks, guided by their care team's recommendations.
Yes, it is possible for the retina to detach again after surgical repair, though many repairs are successful on the first attempt. If redetachment occurs, additional surgery may be recommended. People who have experienced a retinal detachment in one eye also have a higher chance of developing a detachment in their other eye over time. For these reasons, ongoing monitoring with regular dilated eye examinations is an important part of long-term care after retinal detachment.
If you have risk factors for retinal detachment, such as high myopia, a family history of detachment, previous eye surgery, or diabetes, the most important step is to maintain a schedule of regular comprehensive eye examinations. During these visits, your care team at Washington Eye Institute can carefully examine the retina for early signs of thinning, tears, or other changes that may lead to detachment. Catching and treating retinal tears before they progress to full detachment is one of the most effective ways to protect your vision. Talk with your care team about how often you should have your eyes checked based on your individual risk profile.
