Pneumatic retinopexy (pneumatic retinopexy): treatment of retinal detachment
Vision problems often develop unnoticed, but there are conditions that require immediate medical attention. One such dangerous condition is retinal detachment, which disrupts the supply of light-sensitive cells, potentially leading to irreversible blindness.
Modern ophthalmology offers a variety of treatment options, including pneumatic retinopexy, a highly effective and gentle procedure. This minimally invasive method allows for the restoration of tissue anatomical position without complex abdominal surgery.
At the K+31 Clinic, we provide a full cycle of patient care, from emergency diagnostics to careful monitoring during the rehabilitation period.

What is pneumatic retinopexy
In most cases, the problem begins with a retinal tear, through which fluid from the vitreous body penetrates beneath the light-sensitive membrane and separates it from the underlying vascular tissue. Pneumoretinopexy is an outpatient procedure aimed at closing this defect from the inside using microinjection of a special gas.
Principle of the method: gas tamponade and retinal compression
The ophthalmic surgeon injects a microscopic volume of a special substance into the eye. This intraocular gas gradually expands over the first few days after injection. When the patient assumes a certain body position, the gas bubble rises and begins to exert targeted pressure on the damaged area.
This gas tamponade serves two important purposes:
- It mechanically presses the detached inner retinal membrane back against the vascular wall of the eye.
- The gas bubble completely seals the retinal tear, preventing further penetration of intraocular fluid.
Once the membranes are brought together, the doctor can securely fix them to prevent further fluid accumulation. Gradually, the gas in the eye is absorbed on its own, and its place is taken by the natural intraocular fluid.
How does pneumatic retinopexy differ from other treatment methods?
Traditional treatment for retinal detachment often involves surgeries such as vitrectomy or scleral buckling. These techniques require surgery in an operating room, suturing, and prolonged anesthesia.
During vitrectomy, the vitreous is almost completely removed, while during scleral buckling, a special silicone tourniquet is sutured externally to the eyeball. Pneumatic retinopexy is localized and targeted, directly affecting the cause of the detachment.
When is pneumatic retinopexy recommended?
This treatment method has clearly defined application limits, as it is not a universal treatment for all types of ocular pathologies.
Main indications for the procedure
The procedure is effective if the defect is located in the upper half of the fundus—approximately from 8 to 4 o'clock on a clock face. This is because the gas bubble always moves upward, making it technically impossible to provide adequate pressure on the lower parts of the eye.
When is this method particularly effective?
The procedure demonstrates maximum effectiveness in the following situations:
- With a fresh retinal tear that has occurred recently and has not yet caused extensive fibrotic changes.
- With a small detachment, when the affected area is localized and does not affect the central field of vision.
- When it is important to minimize trauma to the ocular tissue, for example, in elderly patients or people with severe concomitant somatic diseases.
- If the patient can maintain a stable head position after the procedure, understanding the importance of this step.
- If the doctor sees a good chance of success with this approach after performing an ultrasound examination of the eye.
When to consider alternatives
Pneumatic retinopexy will be ineffective if the retinal tear is located in the inferior portions of the optic cup, as the gas simply cannot compress this area. This method is also not used if there are multiple defects in different quadrants of the eye. In such advanced cases, the standard treatment is a full vitrectomy, during which the surgeon removes the altered vitreous and straightens the tissue from the inside using heavy water or silicone oil. If an isolated defect is detected without underlying fluid accumulation, laser coagulation of the retina alone can be performed without the introduction of a gas mixture.
How does the procedure work?
Knowing how the procedure works helps reduce anxiety and prepare for treatment.
Preparing for pneumoretinopexy
Before the procedure, the patient undergoes a standard examination. The ophthalmologist dilates the pupil with special drops and cleanses the skin around the eye and the conjunctival cavity with an antiseptic solution to ensure sterility.
Main stages of the procedure
The patient is positioned in the operating chair. The surgeon uses a special microscope to precisely visualize internal structures. A precisely calculated dose of prepared intraocular gas is injected into the eye cavity through a thin needle. At the moment of injection, the patient may notice a dark cloud or floating ball in the field of vision—this is completely normal and indicates that the gas bubble has reached the desired area. Immediately after the injection, the doctor measures the intraocular pressure to ensure the safety of the procedure.
What happens after the gas is injected
After the needle is removed and the pressure has stabilized, laser coagulation of the retina around the tear is performed. Sometimes laser treatment is postponed for a few days, allowing the gas time to fully straighten and compress the tissue.
The laser beams create pinpoint microburns along the edges of the defect. As these points heal, strong adhesions form, firmly attaching the retina to the underlying tissues, preventing re-entry of fluid.
General information
Recovery after pneumorretinopexy
The post-procedure period requires a high level of discipline from the patient, as it is at this stage that the final treatment result is determined.
Head position and diet after the procedure
As soon as the gas in the eye begins to expand, the patient must assume a specific body position. This is called head positioning, and its nature depends on the location of the rupture. The goal is to ensure that the gas bubble constantly rises in the direction of the rupture and maintains its position. This regimen must be maintained for the first few days, including while sleeping.
Restrictions during the recovery period
A proper post-operative regimen includes completely avoiding heavy physical activity, heavy lifting, and sudden downward bending. Do not rub the operated eye with your hands and avoid getting water or soap in it when washing. While the gas bubble remains in the eye, air travel and mountain trips are strictly prohibited. Changes in atmospheric pressure will cause the gas to expand sharply, which can lead to a dangerous spike in intraocular pressure and irreversible vision loss.
When does the effect usually appear and what to monitor?
The patient notices the first signs of improvement within the first few days after the procedure, when the swelling subsides and the compressed membrane begins to perceive light again. As vision recovers, the gray veil or curtain in front of the eye begins to diminish. However, the final quality of vision will only be clear after the gas has completely resolved.

Benefits of pneumatic retinopexy for the patient
This method was chosen due to its high efficiency and minimal impact on the body.
Minimally invasive and gentle
The procedure does not require hospitalization and is performed under local anesthesia, eliminating the toxic effects of general anesthesia on the heart and blood vessels. The patient feels no pain, and the procedure itself takes only 15-20 minutes.
Preservation of ocular anatomy and targeted application
During the procedure, the vitreous body is not removed, preserving all the natural structures and hydrodynamics of the eye. The doctor treats only the problematic area. Since the retina is not subjected to harsh mechanical pressure from the instruments, the risk of postoperative inflammation and long-term complications, such as secondary glaucoma or accelerated cataract development, is reduced.
Our advantages: accurate diagnosis, monitoring, and support
We use expert-grade optical coherence tomography and high-resolution ultrasound scanning, allowing us to detect even the smallest and most hidden tears. Our team, which includes experienced diagnosticians and vitreoretinal surgeons, supports the patient at every stage, from the initial presentation with acute symptoms to complete tissue fusion.
