11/29/2023 0 Comments Bubble in eye after retina surgeryYou must not travel by air or to high altitude for as long as there is a gas bubble in your eye. A gas bubble will gradually dissolve over the next few weeks and disappear – you will have poor vision in the eye whilst it is full of gas, and over the following days and weeks you will recover the vision as the gas bubble gets smaller, starting with the top of your vision. There are two types of gas bubble I generally use, a shorter acting gas, sulphur hexafluoride (SF6), which lasts from 2 to 4 weeks, and a longer acting gas, perfluoropropane (C3F8), which lasts between 4 to 8 weeks. Because the gas always floats upwards, the tear will be supported in the upright position if it is at the top of the eye, but if the tear is on the side, you will be asked to adopt a posture on one side or the other to bring the tear into a the right position for the gas bubble to hold the retina together. The gas bubble floats upwards and holds the two layers of torn retina together until the sealing treatment takes effect – this usually takes about 5 to 7 days. The principle is similar to when you want to stick 2 sheets of paper together, and you put them between two books to hold the wet sides together till the glue dries. The role of the gas bubble is to hold two layers of the retina together whilst the necessary sealing takes place. Some conditions, such as macular holes and retinal detachments routinely need a gas bubble, but a vitrectomy for any condition may require a gas bubble, and the decision is made during the operation if there is a tear in the retina during surgery. Some vitrectomy operations require a gas bubble in the eye at the end of surgery. Not all patients need to posture after vitrectomy surgery and you will be given information on posturing before you are discharged from the hospital. When the vitreous gel is removed it is replaced with saline fluid, gas or oil, and the next section tells you about these and about posturing that you may be required to adopt for a few days after surgery. Usually this fills just the front part of the eye, the anterior chamber, but after vitrectomy it fills the whole eye. Balanced salt solution and gas bubbles will be gradually replaced with an aqueous fluid produced naturally by the inside of the eye. At the end of the operation, it will be replaced with a balanced salt solution, a gas bubble or an oil bubble. The role of the gas or oil bubble is to ‘tamponade’, or hold the layers of the retina in place to secure the retina in the post-operative period. Your eye does not need the vitreous gel, and does not replace or regrow it. The vitreous gel in the back half of the eye is removed as part of the surgical treatment of a range of conditions such as retinal detachment, macular holes, epiretinal membranes, vitreous haemorrhages and advanced complications of diabetic eye disease. A vitrectomy operation is an operation inside the eye, which is done through three small keyhole incisions made on the white of the eye.
