Pneumatic Retinopexy
Pneumatic retinopexy is an in-office procedure to repair a retinal detachment. During this procedure, your ophthalmologist will numb the eye to reduce any discomfort. A freezing treatment or laser is applied to the retina to seal it against the wall of the eye. A gas bubble is then injected into the vitreous cavity of the eye. After the procedure, you will be positioned to allow the bubble to float over the area of the detachment. The purpose of the gas bubble is to push the retina back into its normal position and seal off the area of the retinal tear. If the procedure is successful, the retina will return to its proper position permanently and vision will improve over time.
A pneumatic retinopexy usually takes about 30 minutes. After a pneumatic retinopexy, you may experience eye irritation or redness for a few days. Over the counter pain medications and artificial tears can help with any eye discomfort. You will need close follow-up care with your doctor to determine that the retina is healing properly.
Your ophthalmologist will give you instructions on restrictions and positioning requirements after the procedure. Typically, you will be asked to keep your head in a specific position 3-7 days following the procedure. If you have restrictions to the position requirement it is important to discuss this with your retina specialist before you proceed. Alternative interventions may be available to those who are unable to position for an extended period.
While the gas bubble is in the eye, you will not be allowed to fly, experience a change in altitude, or receive inhaled anesthesia. If you do any of these activities, the gas bubble in your eye will expand, increasing the pressure in the eye which can cause severe pain and may result in permanent blindness. It typically takes 2-4 weeks for the gas bubble to naturally dissolve.
