Vitreomacular traction syndrome (VMTS) is part of a spectrum of diseases having abnormal adhesion between the posterior hyaloid and the macula. It is characterized by incomplete posterior vitreous detachment (PVD) causing morphologic distortion of the fovea. The tractional effects of perifoveal PVD may result in complications such as tractional cystoid macular edema, retinoschisis, impending or full thickness macular hole (FTMH), foveal detachment or epiretinal membrane (ERM).[1,2] Patients with VMTS may present with gradual blurred vision, micropsia, metamorphopsia or scotoma. 
The International Vitreomacular Traction Study (IVTS) Group developed a classification for diseases of vitreomacular interface based on anatomic features in OCT.

VMT can also be classified based on the diameter and morphology of the vitreomacular attachment.
About 20% of VMT cases may spontaneously resolve with vision improvement; 40% show long-term stability and 20% deteriorate or progress to FTMH. For VMT cases which are symptomatic or progress treatment options include: ocriplasmin vitreolysis, pneumatic vitreolysis or vitrectomy.
