Retinal Detachment: Symptoms, Treatment, and Recovery

Retinal detachment can occur at any age but becomes more common after age 40. This is partly because the natural aging process affects the vitreous gel, increasing the chance that it pulls on the retina during separation.

People with high myopia (severe nearsightedness) are at much greater risk because their eyes are longer than average. This extra length stretches and thins the retina, making it more vulnerable to tears. The risk in highly myopic eyes is many times greater than in eyes with normal vision, even before any surgery has been performed.

Cataract surgery is a known risk factor for retinal detachment. While the overall rate is low, certain complications during surgery can raise that risk further. Severe eye injuries from blunt trauma, such as those caused by sports accidents or physical impact, can also cause retinal tears or trigger a detachment.

Lattice degeneration is a condition in which the outer edges of the retina become thin and develop small holes or weak spots. It is more common in people with myopia and is present in a significant portion of retinal detachment cases. Retinoschisis, a condition in which the retinal layers split apart, can also raise the risk. A retina specialist can identify these changes during a dilated eye exam before they lead to detachment.

If you have had a retinal detachment in one eye, your other eye carries a higher risk. A family history of retinal detachment also increases your likelihood. If either of these applies to you, regular dilated eye exams are especially important for catching early signs before vision is affected.

When a tear is caught before the retina has fully detached, a retina specialist can often seal it in the office. Laser photocoagulation uses a focused beam of light to create small treatment spots around the tear, forming scar tissue that bonds the retina to the underlying tissue. Cryopexy uses a freezing probe applied to the outside of the eye to achieve a similar seal. Both procedures prevent fluid from passing through the tear and can stop a detachment from developing.

Pneumatic retinopexy is a procedure in which a small gas bubble is injected into the vitreous cavity of the eye. The bubble rises and presses against the retinal tear, pushing the retina back into contact with the underlying tissue. The patient must maintain a specific head position for several days so the bubble stays over the tear while healing takes place. Laser or cryopexy is then applied to permanently seal the tear. This approach works best for detachments caused by tears in the upper portion of the retina.

A scleral buckle is a small band of silicone placed around the outside of the eye. It gently pushes the wall of the eye inward toward the detached retina, helping it return to its proper position. Laser or cryopexy is used to seal the tear at the same time. The buckle remains on the eye permanently in most cases but is not visible from the outside. This approach is often preferred in younger patients or in certain types of detachments.

Vitrectomy is the most common surgical procedure for retinal detachment. The retina specialist removes the vitreous gel from inside the eye through very small incisions, eliminating any traction on the retina and allowing direct repair of tears. A gas bubble or silicone oil is then placed inside the eye to hold the retina in place while healing occurs. Gas bubbles dissolve on their own over several weeks. Silicone oil may need to be removed in a separate procedure months later.

For complex detachments, particularly those involving PVR or very large tears, a retina specialist may combine vitrectomy with a scleral buckle. Long-acting gas or silicone oil may also be used in these cases to provide longer support during healing. Each treatment plan is tailored to the specific characteristics of the detachment.

While most retinal detachments do produce at least some warning signs such as floaters or flashes, small tears or very slow detachments in the outer edges of the retina can occasionally cause few or no noticeable symptoms. This is more likely in people with high myopia or lattice degeneration, where thinning develops gradually over time. This is precisely why routine dilated eye exams matter so much for high-risk individuals, even when vision seems perfectly normal. An exam can identify a problem and allow preventive treatment before any detachment begins.

Not every type of retinal detachment surgery requires positional restrictions, so your specific instructions will depend on the procedure performed. When a gas bubble is used during vitrectomy, the bubble must press against the repaired area of the retina, and your head position controls where the bubble sits inside the eye. Your retina specialist will tell you exactly how long to maintain positioning and how many hours per day it is required. Following these instructions carefully gives the repair the best chance of success.

If a gas bubble was placed inside your eye, you should not fly until the bubble has fully dissolved. At altitude, the drop in cabin air pressure causes gas to expand. Inside the eye, this expansion can raise pressure to dangerous levels and put the repair at risk. The restriction typically lasts several weeks but depends on the type of gas used, as different gases dissolve at different rates. The same precaution applies to driving to or staying at high-altitude destinations. Your retina specialist will confirm when travel is safe based on your individual progress.

Surgery successfully reattaches the retina in approximately 9 out of 10 cases. However, some patients do require a second procedure, most often due to PVR or new tears developing during healing. The need for additional surgery does not mean the first procedure failed. Complex detachments and those involving PVR carry a higher chance of requiring more than one operation from the outset. Your retina specialist will discuss the likelihood for your specific case before surgery begins.

Yes, in many cases it can. When a retinal tear is identified before fluid has accumulated beneath the retina, a retina specialist can seal it using laser photocoagulation or cryopexy. These in-office procedures create a secure bond around the tear that prevents fluid from passing through. This is one of the clearest examples in eye care where early detection leads to a much simpler and more effective treatment. The key is not waiting once new floaters or flashes appear, since prompt evaluation is what makes early treatment possible.

Posterior vitreous detachment (PVD) is a normal age-related process that often causes a sudden onset of new floaters and sometimes brief flashes of light. In most cases, PVD does not cause a retinal tear. However, in some eyes the separating vitreous pulls a piece of the retina with it, creating a tear. Because both PVD and retinal tears can cause similar symptoms at the start, any new or sudden increase in floaters or flashes should be evaluated by a retina specialist promptly. An examination is the only reliable way to tell whether a tear or detachment has occurred.
