Abstract

The field of vitreoretinal surgery has evolved substantially over the last several decades. Scientific advances have improved our understanding of disease pathophysiology, and new surgical adjuncts and techniques have decreased surgical time and improved patient outcomes. Pharmacologic agents have recently been developed for intraocular use in order to enhance vitreous removal and even as a nonsurgical treatment for pathology due to an abnormal vitreoretinal interface. Plasmin can successfully cause vitreous liquefaction and induce a posterior vitreous detachment. Additionally, ocriplasmin has been approved for symptomatic vitreomacular adhesion and others appear to be promising for pharmacologic manipulation of the vitreous. The ability to induce vitreous liquefaction and a complete posterior vitreous detachment (PVD) with a single intravitreal injection has potential implications for the management of multiple vitreoretinopathies. Enzymatic vitrectomy may help to reduce vitreous viscosity, thereby facilitating removal during vitrectomy and reducing surgical time, especially when using smaller-gauge vitrectomy instruments. The induction of a PVD also has the potential to reduce intraoperative complications. As we improve our understanding of the molecular flux in the vitreous cavity, pharmacologic vitreodynamics will likely become more important as it may allow for improved manipulation of intravitreal molecules.
