Retinal detachment is treated with surgery, and the specific procedure depends on the severity and location of the detachment. There is no medication, eye drop, or home remedy that can reattach a detached retina. With modern surgical techniques, final reattachment rates reach approximately 97 to 99%, though the speed of treatment directly affects how much vision you recover.
Why Timing Matters
The single biggest factor in your visual outcome is whether the detachment has reached your macula, the central area of the retina responsible for sharp, detailed vision. When the macula is still attached, the goal is to operate before the detachment spreads to it, preserving full central vision. When the macula has already detached, every day of delay reduces your chances of recovering good eyesight. A study in BMJ Open Ophthalmology found that 83.5% of patients achieved strong visual acuity when operated on within two days of losing central vision, compared to just 68.7% when surgery was delayed five to seven days.
If you cannot get surgery immediately, your doctor will likely instruct you to hold a specific head position to slow fluid accumulation under the retina. Within the first week, every day counts.
Treating Retinal Tears Before They Detach
A retinal tear is not the same as a retinal detachment. If caught early, before fluid seeps behind the retina and lifts it away, a tear can be sealed in an office visit with one of two techniques.
Laser photocoagulation uses a focused beam of light to create tiny burns around the tear. Over several weeks, these burns form scar tissue that seals the retina in place. Cryopexy achieves the same result by applying a freezing probe to the outside of the eye, creating a seal around the tear from the other direction. Both methods prevent the fluid inside the eye from passing through the tear and getting underneath the retina. Neither requires an operating room, and both are done under local anesthesia.
These procedures only work for tears, not for a detachment that has already progressed. Once fluid has separated the retina from the tissue behind it, surgery is required.
Pneumatic Retinopexy
Pneumatic retinopexy is the least invasive surgical option. Your surgeon injects a small gas bubble into the eye, which floats up against the detached area and presses the retina back into place. Before or after injecting the bubble, the tear itself is sealed with either a freezing probe or laser. In some cases, the gas is injected first, and laser treatment is done a few days later once the retina has flattened.
The gas bubble does the mechanical work, but you do too. You’ll need to hold your head in a specific position for days so the bubble stays pressed against the right spot. The bubble gradually dissolves on its own over two to eight weeks depending on the type of gas used.
Primary success rates for pneumatic retinopexy are around 75 to 81%, meaning one in four or five patients needs a second procedure. However, the final success rate after additional intervention reaches roughly 97 to 99%. This approach works best for straightforward detachments where the tear is in the upper part of the retina.
Vitrectomy
Pars plana vitrectomy is the most commonly performed surgery for retinal detachment today. The surgeon makes tiny incisions in the white of the eye and removes the vitreous, the gel-like substance filling the eye’s interior. This eliminates any pulling forces on the retina and gives the surgeon direct access to flatten the retina back into position and seal any tears with laser.
Once the retina is reattached, the eye needs something to hold it in place while it heals. Two types of tamponade are used. Gas bubbles are most common: one type lasts two to three weeks, another lasts six to eight weeks. The gas slowly absorbs and is replaced by fluid your eye naturally produces. In more complex cases, silicone oil is used instead. Oil stays in the eye permanently until it is removed in a second surgery, and it’s typically chosen for patients who cannot maintain positioning requirements, who have only one functional eye, or who need to fly (gas bubbles expand dangerously at high altitude).
Primary reattachment rates for vitrectomy are in the 85 to 93% range depending on the complexity of the case. For high-risk detachments, combining vitrectomy with a scleral buckle improves first-surgery success from about 67% to roughly 81%.
Scleral Buckle
A scleral buckle is a band of silicone material sutured to the outside of the eye. It gently pushes the wall of the eye inward, closing the gap between the detached retina and the tissue behind it. This relieves the pulling forces that caused the tear, pushes fluid away from the break, and changes the shape of the eye so that internal fluid currents no longer drive liquid under the retina.
The buckle is permanent but sits beneath the outer membrane of the eye, so it isn’t visible. While scleral buckling has declined in popularity relative to vitrectomy, it remains a valuable technique, particularly in younger patients and in cases where it can be combined with vitrectomy for a stronger result.
What Recovery Looks Like
If your surgery involved a gas bubble, you will need to maintain a face-down or sideways position at all times, including while standing, sitting, eating, walking, and sleeping. Your surgeon will specify the duration, which ranges from several days to several weeks depending on the location and severity of the detachment. This is the most physically demanding part of recovery, and special equipment like face-down pillows and chair supports can make it more manageable.
You’ll typically see your surgeon the day after surgery, again at one week, and then at roughly one month if there are no complications. Vision is often blurrier immediately after surgery than it was before, which can be alarming but is expected. Improvement happens gradually and can continue for up to a year.
During recovery, you cannot fly or travel to high altitudes if you have a gas bubble in your eye. You’ll also need to avoid strenuous activity for several weeks. If you need general anesthesia for any other procedure while a gas bubble is present, your anesthesiologist must be informed, as certain anesthetic gases can cause the bubble to expand.
Potential Complications
The most significant complication is proliferative vitreoretinopathy, or PVR, where scar tissue forms on the retina’s surface and causes it to detach again. This occurs in about 10% of all retinal detachment cases and is the most common reason a first surgery fails. PVR typically requires additional surgery to address.
Cataract formation is extremely common after vitrectomy. Roughly half of vitrectomy patients need cataract surgery within one year, and 80% develop a visually significant cataract within two years. If you already have a cataract or are over 50, your surgeon may discuss combining cataract removal with the detachment repair.
Elevated eye pressure after surgery affects about one quarter of patients. Steroid eye drops used during recovery can raise pressure further in about one third of patients. This is usually managed with temporary pressure-lowering drops and monitored closely at follow-up visits.
How Much Vision You Can Expect to Regain
Your visual outcome depends primarily on whether the macula was involved and how quickly you were treated. If the macula stayed attached throughout, most people recover excellent central vision. If the macula was detached, recovery is more variable. Many patients regain functional vision, but some degree of distortion, reduced sharpness, or difficulty with fine detail is common even after a structurally successful repair.
Final reattachment rates across all techniques reach 97 to 99% after one or more procedures. The retina stays attached permanently in the vast majority of cases once successfully repaired, though you’ll need periodic eye exams to monitor for new tears, especially in the first year and in your other eye.
