Purpose To evaluate the natural course of idiopathic vitreomacular traction (VMT) with spectral-domain optical coherence tomography (SDOCT) from the vitreomacular adhesion (VMA) stage to the spontaneous resolution of VMT. Design Prospective observational case series. Methods We studied the natural course of idiopathic VMT in 46 eyes (46 patients), divided into those that proceeded to spontaneous VMT resolution (12 cases) and those that remained at the VMT stage (34 cases). All patients were examined with SDOCT at regular 3-month intervals. We recorded the vitreomacular angle of VMA nasally and temporally, the horizontal diameter of VMA, macular thickness, visual acuity, photoreceptor layer, and external limiting membrane. Results In the 12 eyes that proceeded to spontaneous resolution, the vitreous adhesion angle had a mean increase of 38 degrees at VMT, compared to the angle at the VMA stage. In the 34 eyes that remained at the VMT stage, the mean angle of traction increased by only 1 degree throughout follow-up. In all 46 patients, the angle at the VMT stage was significantly associated with traction resolution (nasally P =.001, temporally P <.001). The likelihood of resolution was more than 99% lower for patients with a VMT diameter >400 μm compared with that of eyes with a VMT diameter <400 μm. Patients with broad-type VMT remained at the same stage, whereas patients with V-type VMT had 80% probability of resolution. Conclusions Spontaneous VMT resolution is negatively associated with the horizontal adhesion diameter. The strength of the traction exerted by the vitreous on the fovea seems to be positively related to the size of the vitreomacular angle. © 2014 BY ELSEVIER INC. ALL RIGHTS RESERVED. (EN)
