Pneumatic retinopexy is a minimally invasive procedure to repair selected retinal detachments using a gas bubble inside the eye. It avoids large incisions and is often performed in the clinic.
Procedure
After treating the retinal tear with cryotherapy or laser, the surgeon injects a small gas bubble into the vitreous cavity. The patient then maintains specific head positioning so the bubble presses against the tear, allowing the retina to reattach.
- Suitable mainly for simple, superior retinal breaks in cooperative patients
- Gas gradually absorbs over days to weeks
- Patients must avoid flying and high altitudes while gas is present
- Additional laser or surgery may be needed if detachment recurs
Advantages and Limitations
Pneumatic retinopexy offers faster recovery and less discomfort than some alternative surgeries, with good outcomes when carefully selected. However, success rates can be lower than vitrectomy or buckle in more complex cases.
- Strict adherence to positioning instructions is crucial
- Complications include new tears, raised pressure, or persistent detachment
- Follow‑up visits are frequent in the early period
- Decision between techniques is made by the retinal specialist based on detachment pattern
