Intravitreal Gas
Intravitreal gas is a specialised treatment sometimes used during eye surgery to support the retina as it heals. A gas bubble is injected into the vitreous cavity to act as an internal tamponade (pressure). This helps keep the retina in the correct position after treatment for conditions such as retinal detachment, retinal tear, macular hole, epiretinal membrane, or submacular haemorrhage.
Vision with Intravitreal Gas
While the gas bubble is present, vision will be significantly blurred. Many patients describe the bubble as looking through water or seeing a moving line like a spirit level. The bubble gradually dissolves over 1–4 weeks, sometimes breaking into smaller bubbles before disappearing.
Recovery and Healing
Patients are often required to maintain a face‑down posture to ensure the gas presses onto the correct retinal area. Flying, high‑altitude travel, and nitrous oxide anaesthesia must be avoided until the bubble is gone. An alert bracelet is provided and must be worn until the gas bubble has been absorbed.
Intravitreal Gas Frequently Asked Questions
How long does the gas bubble stay in the eye?
The gas bubble may remain for several days to several weeks depending on the type of gas used.
Will I be able to see while the gas bubble is present?
Vision will be blurred or limited while the bubble remains, but it gradually improves as the gas absorbs.
Can I travel after intravitreal gas treatment?
Air travel and high-altitude locations must be avoided until the gas bubble has fully absorbed.
Is intravitreal gas painful?
Most patients experience mild discomfort rather than pain, which is usually well managed with medication.
