“…More in detail, a tamponading agent with high interfacial tension, such as gas or perfluorocarbon liquids (PFCL), will not readily sneak into the subretinal space through retinal tears because to do so, it would need to increase its surface area. This process requires the application of a high enough energy to supersede the Van der Waals forces, and therefore it can happen only when, for example, the gravity force applies energy on a PFCL bubble sitting over a stiffened, teared retina, possibly leading to the feared complication of retained subfoveal PFCL [ 54 , 55 , 56 ].…”

Vitreous substitutes are indispensable tools in vitreoretinal surgery. The two crucial functions of these substitutes are their ability to displace intravitreal fluid from the retinal surface and to allow the retina to adhere to the retinal pigment epithelium. Today, vitreoretinal surgeons can choose among a plethora of vitreous tamponades, and the tamponade of choice might be difficult to determine in the ever-expanding range of possibilities for a favorable outcome. The currently available vitreous substitutes have disadvantages that need to be addressed to improve the surgical outcome achievable today. Herein, the fundamental physical and chemical proprieties of all vitreous substitutes are reported, and their use and clinical applications are described alongside some surgical techniques of intra-operative manipulation. The major upcoming developments in vitreous substitutes are extensively discussed, keeping a translational perspective throughout. Conclusions on future perspectives are derived through an in-depth analysis of what is lacking today in terms of desired outcomes and biomaterials technology.
