Video answer: Detached retina: vitrectomy
Top best answers to the question «Retinal detachment gas bubble»
- After sealing a retinal tear with cryopexy, a gas bubble is injected into the vitreous. The bubble applies gentle pressure, helping a detached section of the retina to reattach to the eyeball. If your retina has detached, you'll need surgery to repair it, preferably within days of a diagnosis.

Your retina specialist may inject a gas bubble to fix your retina. Many retina repairs require direct access to the torn, scarred, detached, or damaged retina. To do that your retina specialist will perform a vitrectomy and remove the vitreous humor gel, repair the retina, and then inject a gas bubble to wall off the repaired retina to allow it to heal.
The most common reasons to use a gas bubble are to tamponade a retinal break, repair a retinal detachment, or repair a full-thickness macular hole. The time frame required for the gas bubble to...
Gas bubbles and laser can be used to repair retinal detachments. You should ask your retinal surgeon what type of gas was used and how long he or she anticipates it being present for. There are typically two types of gases that we use.
Tractional retinal detachments are caused by scar tissue that grows on the surface of the retina and pulls the retina off the back wall of the eye. This type of retinal detachment may occur from diabetes or other conditions. Exudative (ex OO day tive) retinal detachments form when fluid leaks out of blood vessels and accumulates under the retina.
Depends on type: A simple retinal detach can be fixed in the office with a procedure called a pnuematic retinopexy. A gas bubble is injected in the eye followed by cr...

Lower Success Rate – not all retinal detachments can be treated with gas injection. The forces within the vitreous are NOT changed. After gas is injected, the head must be positioned so that the gas abuts the retinal tear. For instance, if the tear is at the “12 o’clock” position of the eye, the head must be held upright, or erect.
But the bubble is there to push the retina back and hold it in place as it heals. Therefore, the gas bubble is your friend… be patient with it! Below, you will find two photos, which are my visual attempts to describe what it looks like as the gas bubble starts to disperse.
The timing depends on the type of gas used: short-acting gas (SF6) takes 2 to 3 weeks to disappear; long-acting gas (C3F8) takes about 2 months. When the gas bubble is down to half size, you will see a horizontal line across your vision, bobbing up and down with head movement. This is where the gas meets the fluid which is gradually replacing it.
