Silicone oil is injected inside the eye, usually due to the presence of a disease such as retinal detachment, which is why a special material like silicone oil needs to be filled to maintain the normal position of the retina and to promote retinal repositioning, thus restoring normal visual function. In the case of silicone oil injection, a special position needs to be maintained, either prone or right or left lateral, depending on the extent of the retinal detachment or the location of the fissure. There are two main reasons for the prone position: first, to promote the recovery of the retina; second, to avoid the formation of secondary glaucoma as a complication. Therefore, in the state of intraocular silicone oil filling, it is important to maintain a reasonable body position, which is the only way to make the recovery of the disease faster. If the correct position is not maintained, it is likely to lead to poor retinal repositioning or secondary glaucoma.
