Pneumatic retinopexy is an eye procedure that uses a small gas bubble to press the retina back into place so it can seal and heal. Doctors use this method for specific types of rhegmatogenous retinal detachment—that’s when a tear in the retina lets fluid slip underneath and lift the retina off the back wall of the eye. In PR, your eye doctor (1) closes the tear with a cold treatment (cryotherapy) or laser and (2) injects a tiny gas bubble that floats up and gently pushes the retina flat while the seal strengthens. It’s usually done in the clinic with numbing medicine. In properly selected patients, PR can reattach the retina and save vision with less cutting, less time, and faster recovery than some operating-room surgeries. AAOEyeWiki

Pneumatic retinopexy (often shortened to PR) is a minimally invasive eye procedure that uses a tiny gas bubble to help the retina re-attach to the back of the eye.

The retina is a thin, sensitive layer of tissue lining the inside of the eye. It acts like the film or sensor in a camera. It turns light into signals that your brain can read as vision.

Sometimes a small tear or hole forms in the retina. Fluid from inside the eye can pass through that tear. The fluid lifts the retina and peels it off the inner wall. This is called a rhegmatogenous retinal detachment. If the retina stays detached, vision can be lost.

PR tries to seal the tear and push the retina back against the eye wall. The doctor places a small gas bubble inside the gel-filled part of the eye (the vitreous cavity). The bubble gently floats upward and presses on the area of the tear. This closes the leak so the retina can settle back into place. The doctor also uses cold therapy (cryopexy) or laser spots around the tear to weld it shut. The weld makes a permanent seal over several days.

PR is usually done in the office with numbing drops and a small injection. Most people go home the same day. You must keep a specific head position after the procedure so the bubble stays right over the tear. You cannot fly or travel to high mountains while a gas bubble is in your eye because gas expands with lower air pressure.

Pneumatic retinopexy is a gas-bubble repair for a selected type of retinal detachment. The doctor identifies the tear that started the detachment. The doctor then seals that tear with laser or freezing. The doctor also injects a tiny bubble of medical gas into the eye. The gas floats and pushes on the tear from the inside. The push stops the leak. The fluid under the retina is then absorbed by the eye over time. The retina re-sticks to the wall. The laser or cold scars make the seal strong and long-lasting.

This method works best when the tears are small, located near the top of the retina (so the bubble can reach them), and the area of detachment is not too large. It is less invasive than some other surgeries. It often has a quicker recovery and less discomfort. It needs careful patient positioning, clear patient instructions, and close follow-up.

Types of pneumatic retinopexy

Different eyes and different tears need small changes in technique. Doctors adjust details so the bubble and the seal work safely. Here are practical “types” or variants of PR you may hear about:

Primary PR vs. Secondary PR
Primary PR is the first treatment used for the detachment. Secondary PR is used after another method fails or if a small, new tear appears and is suitable for a bubble repair.
PR with cryopexy vs. PR with laser
Cryopexy uses a cold probe on the outer eye to freeze the area around the tear. Laser uses light burns inside the eye to seal around the tear. The choice depends on tear location, clarity of the eye, and doctor preference.
Different medical gases (SF6 vs. C3F8 vs. air)
SF6 gas expands a bit and lasts a shorter time. C3F8 gas expands more and lasts a longer time. Filtered air can be used in very select cases and lasts a brief time. Longer-lasting gas needs longer positioning and longer flight restrictions.
Single-bubble vs. “double-bubble” technique
Most cases use one bubble. Rarely, doctors may place two small bubbles in special situations to reach a certain tear shape, but one bubble is the standard way.
Office-based PR vs. operating-room PR
Most PR is office-based with numbing drops. Some cases are done in an operating room if the eye is very sensitive, if extra sterility is needed, or if additional steps are planned.
PR with anterior chamber paracentesis vs. without
A paracentesis is a tiny fluid release at the front of the eye to control pressure right after the gas injection. Some eyes need this, and some do not. The doctor decides during the procedure.
Chandelier-assisted PR vs. standard PR
In some centers, a small light source (“chandelier”) helps the doctor visualize the retina while using both hands. Standard PR uses indirect lenses and lights without a chandelier. Both aim to see clearly and treat precisely.
PR with early laser vs. PR with delayed laser
Sometimes the doctor does laser immediately after the gas injection. Sometimes the doctor waits a day or two until the retina is more flat, and then adds laser spots for a cleaner seal.
Position-specific PR (upright, side-lying, or face-down)
The head position depends on where the tear is. If the tear is at the top of the retina, you may sit upright. If it is near the side, you may lie on a specific side. If it is near the back, you may need face-down time. Proper position helps the bubble press exactly where it should.
PR combined with barrier laser elsewhere
The doctor may add extra laser rows in nearby weak areas to prevent new detachments. This is common when there is lattice degeneration or other thin spots.

Causes and risk factors

These are common reasons a retinal tear forms or a detachment begins, which may make someone a candidate for PR if the tear pattern is suitable. Some items are risks, and some are events that directly cause a tear.

Age-related vitreous separation (posterior vitreous detachment)
The eye’s gel shrinks and pulls away from the retina with age. A strong tug can tear the retina.
Lattice degeneration
Thin patches in the retina increase the chance of small holes or flap tears.
High myopia (nearsightedness)
A longer eye makes the retina thinner and stretched, which raises the risk of tears.
A sudden hit to the eye (blunt trauma)
A blow can produce a retinal tear, especially near the edge of the retina.
Penetrating eye injury
A sharp object can cut the retina and cause a detachment.
Prior retinal detachment in the other eye
If the fellow eye had a detachment, the risk is higher in the second eye.
Family history of retinal detachment
Some families have weaker retinal tissue or shared risk traits.
Previous eye surgery (especially cataract surgery)
Surgery changes the vitreous and can lead to tears later.
YAG laser capsulotomy after cataract surgery
This common laser to clear the posterior capsule can be linked to a later tear in some cases.
Chronic eye rubbing
Strong rubbing can stress the retina’s edges in a vulnerable eye.
Connective tissue disorders (e.g., Marfan, Stickler)
These conditions can make the eye longer or the tissues looser, which raises tear risk.
Retinal dialysis (often from trauma)
The retina pulls away at its front edge, creating a long break.
Giant retinal tear risk factors
Certain eyes are prone to very large tears; note that PR is usually not used for giant tears, but the underlying risk is still relevant.
Atrophic round holes in thin retina
Tiny round holes can slowly leak fluid and start a detachment.
Areas of old inflammation
Healed scars can be weak and may tear if the vitreous pulls.
Severe short-term physical strain
Intense strain can shift the vitreous and unmask a weak point, though this is less common.
Rapid acceleration or deceleration injuries
Whiplash-type forces can tug on the vitreous and tear the retina.
Peripheral retinal thinning from long-term myopia
Long-standing near-sighted eyes often develop edge thinning, predisposing to tears.
Eye infections or severe inflammation in the past
These can change the vitreous and retina in ways that increase risk.
Prior cryo or laser scars that are incomplete
Rarely, old weak spots near scars can open later if the vitreous pulls again.

Important note: Pneumatic retinopexy is not for every detachment. It is best for specific tear locations and sizes, usually near the top of the retina, with a limited area detached. Your surgeon will explain if your case fits this method.

Common symptoms

These symptoms do not prove a detachment by themselves, but they are warning signs. Anyone with these symptoms should see an eye doctor urgently.

Sudden new floaters
Little dots, cobwebs, or specks that were not there before.
Flashes of light
Brief streaks or sparkles, especially in the side vision, when the vitreous tugs on the retina.
A gray curtain or shadow
A dark area sliding in from the side, top, or bottom of the visual field.
Peripheral vision loss
The edges of vision feel missing or blacked out.
Blurred central vision
If the detachment reaches the macula, straight-ahead vision becomes blurry.
Wavy or distorted lines
A straight line looks bent or wiggly (metamorphopsia).
Sudden drop in reading or face recognition
Fine detail becomes hard to see.
Dark floaters like soot or pepper
This can suggest bleeding in the vitreous from a fresh tear.
A sense of a film over the eye
Vision seems hazy or foggy.
Trouble seeing in dim light
Night vision seems worse than before.
Color dullness
Colors may look less bright or washed out if the macula is involved.
A moving shadow that changes with eye movement
The shadow may shift as you move your eyes because the fluid under the retina moves.
Headache around the eye
Sometimes there is mild pain or pressure, but many detachments are painless.
Double edges on objects
Objects may have a ghost edge if the retina is uneven.
Sudden troubles with depth or side awareness
People may bump into things on the affected side.

Diagnostic tests

Doctors use a step-by-step plan. They start with history and simple checks. They then use special lenses, lights, and scans. Some tests help with safety before treatment. Below are 20 tests grouped into Physical Exam, Manual Tests, Lab/Pathology, Electrodiagnostic, and Imaging.

A) Physical exam

Visual acuity (distance and near)
You read a chart. The doctor measures how sharp your vision is. A drop can signal a macular detachment or optical blur from fluid.
Pupil exam and relative afferent pupillary defect (RAPD)
The doctor shines a light in each eye. Pupils should constrict normally. An RAPD may suggest serious retinal or optic nerve involvement.
Confrontation visual fields
The doctor checks your side vision by wiggling fingers in different quadrants. A missing area can match the detached region.
External eye and eyelid inspection
The doctor looks for trauma marks, old scars, or inflammation that might explain how the detachment started.

B) Manual tests and slit-lamp–based examination

Intraocular pressure (tonometry)
The pressure may be lower in a detached eye. Measuring pressure helps safety and planning.
Slit-lamp exam of the anterior segment and vitreous
The doctor looks for pigment cells (“tobacco dust”), blood, or inflammation in the gel. These can indicate a fresh retinal tear.
Dilated indirect ophthalmoscopy with scleral depression
After dilating drops, the doctor uses a bright headlight and a hand-held lens to see the peripheral retina. A soft depressor on the eyelid helps expose tiny tears. This is often the key test.
Amsler grid or simple line distortion check
You look at a square grid. Wavy lines or missing boxes suggest macular involvement.

C) Laboratory and pathological tests

These tests do not diagnose detachment directly. They are used to make treatment safer and to plan anesthesia or healing. Your doctor orders only what is appropriate for you.

Complete blood count (CBC)
Checks anemia, infection signs, or platelet levels if there is bleeding risk.
Blood glucose or HbA1c
Poorly controlled diabetes can affect healing and risk of swelling after treatment.
Coagulation profile (PT/INR, aPTT)
If you use blood thinners or have a bleeding tendency, this helps plan safe procedures.
Infectious disease screening when indicated
Tests (for example, hepatitis or HIV) are sometimes done for surgical safety and team protection, based on history and local protocols.

D) Electrodiagnostic tests

Full-field electroretinography (ERG)
This test measures the electrical response of the whole retina to light flashes. It helps judge overall retinal function, especially if the view is cloudy.
Multifocal ERG (mfERG)
This maps many small areas of retinal function. It is useful when the macula is involved and the view is clear.
Electro-oculography (EOG)
This measures retinal pigment epithelium function. It can support complex cases where tissue health is questioned.
Visual evoked potential (VEP)
This looks at the signal from the eye to the brain. It helps in cases where optic nerve or brain pathways may also be affecting vision.

E) Imaging tests

B-scan ocular ultrasonography
A sound-wave scan shows the shape of the detached retina and any vitreous hemorrhage when the doctor cannot see the retina directly (for example, due to a dense cataract or bleeding).
Optical coherence tomography (OCT) of the macula
A light-based cross-section scan shows fine layers of the macula. It reveals fluid, folds, or small holes and helps plan urgency and follow-up.
Wide-field color fundus photography
A panoramic photo documents the location of tears, amount of detachment, and laser or cryo scars. It helps track healing over time.
Fundus autofluorescence or fluorescein angiography (as needed)
These scans check the health of the retinal pigment epithelium and blood flow. They are used when fine detail about tissue health may change treatment steps.

Non-pharmacological treatments (therapies & other supports)

(These support healing and safety around pneumatic retinopexy. Your surgeon’s instructions always come first.)

Head positioning (“posturing”).
Purpose: Keep the bubble sealing the tear.
Mechanism: Gravity floats the bubble to press on the tear edge so the laser/cryotherapy can form a firm scar.
Strict activity modification.
Purpose: Reduce eye jarring that could shift the bubble.
Mechanism: Avoid running, lifting, or straining that spikes pressure or moves the bubble off the tear.
No air travel or high altitude while gas is present.
Purpose: Prevent dangerous pressure rise.

Sleep in the advised position.
Purpose: Maintain continuous tamponade even at night.
Mechanism: The bubble must rest under the tear for many hours to help sealing.
Eye shield protection.
Purpose: Prevent accidental rubbing or bumping.
Mechanism: A rigid shield blocks pressure or dirt getting into the eye.

(Why pressure control matters: gas can elevate IOP; surgeons monitor and treat if needed.) PMC

Dietary molecular supplements

Supplements do not reattach a retina. They can support general eye and body health while you heal. Discuss with your doctor, especially if pregnant, on blood thinners, or have kidney/liver disease.

AREDS2-style antioxidant mix (vitamin C 500 mg, vitamin E 400 IU, zinc 80 mg zinc oxide, copper 2 mg, lutein 10 mg, zeaxanthin 2 mg)—Function: antioxidant support for macular health; Mechanism: reduces oxidative stress; Dose: as labeled. Evidence applies to AMD, not RD. JAMA NetworkNational Eye InstituteOffice of Dietary Supplements
Omega-3 fatty acids (EPA+DHA). Function: membrane and anti-inflammatory support; Mechanism: integrates into photoreceptor and RPE cell membranes; Dose: common daily intake ~1 g EPA+DHA from diet/supplement unless your clinician advises otherwise. Office of Dietary Supplements
Lutein. Function: macular pigment support; Mechanism: filters blue light and quenches free radicals; Dose: commonly 10 mg/day (often paired with zeaxanthin). JAMA Network
Zeaxanthin. Function: macular pigment; Mechanism: antioxidant at the fovea; Dose: commonly 2 mg/day with lutein. JAMA Network
Vitamin D. Function: bone/immune health; Mechanism: modulates inflammatory signaling; Dose: typical 600–800 IU/day, and do not exceed 4,000 IU/day without medical advice. Office of Dietary Supplements+2Office of Dietary Supplements+2

Regenerative / stem-cell / immune-booster” approaches

There are no approved “immunity booster” or stem-cell drugs proven to help retinal detachment heal after PR. Giving dosages for such products would be unsafe and misleading. Below are experimental avenues you may hear about; they are not standard of care and no dosing is recommended:

iPSC-derived photoreceptor transplants – lab-grown light-sensing cells; studied for degenerations, not acute detachment.
RPE (retinal pigment epithelium) cell therapy – sheet or suspension implants for atrophy diseases.
Neurotrophic factors (e.g., CNTF) – proteins aimed at protecting photoreceptors in degenerations.
Gene-therapy vectors – targeted to inherited retinal disease; not used for routine RD.
Exosome-based biologics – early research for inflammation modulation.
Systemic “immune boosters” (herbal blends, high-dose vitamins) – not shown to improve PR outcomes and may interact with medicines.

If you are curious about clinical trials, ask your retina specialist to search reputable registries for you.

Surgeries and procedures used in this space

Pneumatic retinopexy (this procedure).
Why done: Office-based option for specific detachments with superior breaks. Procedure: Cryo/laser + gas bubble + positioning. AAO
Laser retinopexy (photocoagulation).
Why: Seals small retinal tears/holes or “barricades” areas at risk. Procedure: Outpatient laser makes a ring of tiny burns that scar and seal the edges.
Cryotherapy.
Why: Seal tears when laser is not ideal (poor view). Procedure: A cold probe freezes the tear from outside; healing scar forms as it thaws.
Scleral buckle (SB).
Why: Time-tested operating-room surgery for many detachments, including inferior tears or lattice with multiple breaks. Procedure: A soft band is stitched to the eye’s outer wall to support and close the tear from outside; often combined with drainage and cryo/laser. PubMed
Pars plana vitrectomy (PPV).
Why: Detachments with cloudy media, many breaks, strong traction, or PVR. Procedure: Surgeon removes the gel (vitreous), relieves traction, applies laser, and fills the eye with gas or silicone oil. EyeWiki

Prevention tips

Get urgent care for new flashes, floaters, or a curtain/shadow.
Keep regular dilated eye exams, especially if you’re highly myopic or had eye surgery/trauma.
Protect your eyes during sports and work to reduce trauma.
Manage diabetes and blood pressure to protect vessels.
Don’t rub your eyes hard—can worsen vitreous traction.
Follow post-cataract and YAG capsulotomy instructions carefully.
Quit smoking to improve retinal blood flow.
Know family history of retinal tears/detachment and tell your doctor.
Treat lattice degeneration or symptomatic tears when your specialist recommends it.
Maintain healthy weight and activity for general vascular health.

When to see a doctor

Seek emergency eye care the same day if you notice a sudden shower of floaters, bright flashes of light, or a dark curtain/veil in your vision.
Call immediately if pain, severe redness, sudden vision drop, bad headache with nausea/vomiting, or if your post-op eye seems worse.
Keep all scheduled follow-ups after PR; new breaks can appear and are treatable if caught promptly. AAO

What to eat and what to avoid

Eat: Fatty fish (salmon, sardines, mackerel) 2–3 times/week for natural omega-3s. Avoid: Large predatory fish excess (mercury risk). NCCIH
Eat: Colorful leafy greens (spinach, kale) for lutein/zeaxanthin.
Eat: Citrus, berries, peppers for vitamin C; nuts/seeds for vitamin E.
Eat: Lean proteins (eggs, legumes, poultry) to support tissue repair.
Eat: Whole grains and plenty of water for bowel regularity (less straining).
Limit: Alcohol (can dehydrate and worsen sleep/positioning).
Limit: High-sodium ultra-processed foods if you have pressure or cardiovascular concerns.
Avoid: Herbal “blood thinners” (like high-dose ginkgo) unless cleared by your doctor.
Avoid: Excess vitamin D or A—stick to safe limits; more is not better. Office of Dietary Supplements+1
Focus: Overall balanced diet—you cannot “eat a detachment away,” but you can fuel recovery.

FAQs

1) Is PR painful?
Most people feel pressure, not sharp pain. Numbing medicine is used. Mild soreness afterward is common and usually managed with drops and simple pain relievers.

2) How long does the gas bubble last?
It depends on the gas. SF₆ often lasts about 2–3 weeks; C₃F₈ can last longer (several weeks). Your vision looks like you’re looking through a waterline until it absorbs. PubMed

3) Why can’t I fly after PR?
At altitude the bubble expands, which can dangerously raise eye pressure and damage vision. Wait until your surgeon confirms the gas is gone.

4) Will I need more than one procedure?
Sometimes. If a new or missed tear appears, your doctor may add laser, reinject gas, or recommend buckle or vitrectomy. PMC

5) Is PR as good as scleral buckle or vitrectomy?
For the right case, PR can work very well with fewer certain downsides, but some reviews show more recurrences vs buckle. The “best” choice depends on your detachment and your surgeon’s exam. PubMedCochrane Library

6) What positions will I have to keep?
Your team will tailor this so the bubble sits on the tear—sometimes face-down, sometimes side-lying, sometimes upright for certain break locations. Hong Kong Journal of Ophthalmology

7) Will I see the gas bubble?
Yes. It looks like a dark, moving circle with a shimmering line. As it shrinks, it becomes a small floating sphere and then disappears.

8) Can I drive?
Not until your doctor says it’s safe. Depth perception and vision are altered with a gas bubble, and you may need to avoid driving for days to weeks.

9) What are the danger signs after PR?
New floaters or flashes, a curtain or shadow, pain, redness, pus, or a sudden drop in vision—call urgently.

10) Can I lie flat on my back?
Usually no if the bubble must cover an upper tear; back-lying can pull the bubble off the tear. Follow your customized plan. Hong Kong Journal of Ophthalmology

11) What about work and exercise?
Most people reduce activity for at least a week or more; heavy lifting, running, and contact sports are off-limits until cleared.

12) Are both eyes at risk?
Your other eye may have similar risk factors. Regular checks help find silent weak spots early.

13) Do vitamins cure retinal detachment?
No. Supplements can support overall eye health but do not reattach a retina. Surgery (PR, buckle, or vitrectomy) is what treats detachment. AAO

14) What if I already had cataract surgery?
Success rates can differ in pseudophakic eyes, partly because small or new tears can be harder to find; your doctor will advise the best approach. EyeWiki

15) How soon will my vision recover?
Some vision returns quickly as the retina flattens, but full recovery takes weeks to months. Final vision depends on how long the macula was detached and other eye health factors.
