BACKGROUND: The vitreoretinal interface is not merely the space between the vitreous body and the retina but it is also a site for highly complex pathologies with the vitreous body exerting an influence on all the neighbouring structures. METHODS: A literature search was performed in Pubmed and current book articles RESULTS: This review article highlights the role of the vitreous body in vitreomacular adhesion and traction, in the development of macular holes and epiretinal membranes as well as its role in age-related macular degeneration. In the retinal periphery the vitreous structures play a pivotal role in retinal tears and detachment as well as in diabetic and other proliferative vitreoretinopathies. The role of the vitreous bodyin the emergence of various forms of cataract is often underestimated. DISCUSSION: Vitreo-etinal surgeons should thoroughly understand the pathophysiological relationship between the vitreous body and the neighboring structures, especially in the era of medical vitreolysis.

Scleral suture fixation is one of several techniques used for secondary lens implantation in cases of inadequate capsular support for which many variations have been published. A transscleral suture can be accomplished using either an external or internal approach. The lens can be implanted using an injector with large incisions for unfolding lenses or also via small self-sealing incisions. Episcleral fixation of the suture can be accomplished by protecting the knot under scleral flaps, intrascleral rotation of the knot and using sclerocorneal pockets or scleral grooves. The intrascleral Z-suture with five intrascleral passes of the suture is a knotless technique providing several advantages.
