title: Vitreomacular traction syndrome.
abstract: The advent of new technologies such as high definition optical coherence tomography (OCT) has not only provided unprecedented imaging capabilities, but also raised the need to define concepts not yet settled and often confusing such as the vitreomacular traction (VMT) syndrome. While technological advances drive us into the future by clarifying the pathophysiology of many diseases and enabling novel therapeutic options, it is at the same time necessary to review basic disease concepts in addition to definitions and classifications. VMT syndrome is implicated in the pathophysiology of a number of macular disorders, translating into a variety of anatomical and functional consequences underscoring the complexity of the condition. These macular changes are closely related to the VMT configuration and have led to proposing classification of this syndrome based on OCT findings. The size and severity of the remaining vitreomacular attachment may define the specific maculopathy. Focal VMT usually leads to macular hole formation, tractional cystoid macular edema and foveal retinal detachment, while broad VMT is associated with epiretinal membranes, diffuse retinal thickening and impaired foveal depression recovery. Despite similar postoperative visual acuity (VA) in focal and broad VMT subgroups, visual improvement is greater with focal VMT because preoperative VA is frequently lower. Surgical procedures are effective to relieve VMT and improve VA in most eyes; outcomes vary with VMT morphology and the duration of symptoms.
