4 Although the pathogeneses of these diseases are not completely understood, 3, 4 OCT has implicated anteroposterior tractional force as a reasonable cause. Currently, it is believed to contribute to a wide spectrum of macular diseases, including cystoid macular edema (CME), macular holes (MHs) and epiretinal membranes (ERMs). 4 In the past, VMT syndrome was considered an isolated pathology. The advent of a new method of high-definition optical coherence tomography (HD-OCT) has provided new insight into vitreomacular traction (VMT) syndrome through improved evaluation of the tractional forces at the vitreoretinal interface 1, 2, 3 and the relationship of these tractional forces with specific macular conditions. V-shaped and focal VMT led to tractional CME and MH, while J-shaped and broad VMT were associated with ERM and diffuse retinal thickening. ConclusionsĪlthough highly concordant, the classification based on the diameter of the adhesion and not on the classical adhesion morphology seemed to better reflect the specific macular changes. The best-corrected visual acuity (BCVA) was not significantly different between the groups (BCVA logarithm of the minimum angle of resolution: V-shaped, 0.45 J-shaped, 0.46 P=0.816 and focal, 0.50 broad, 0.42 P=0.198). V-shaped VMT ( n=29) and focal-VMT ( n=25) led to tractional cystoid macular edema (CME 79.31% and 84%, respectively) and macular hole (MH 37.93% and 44%) J-shaped VMT ( n=24) and broad-VMT ( n=28) were associated with epiretinal membranes (ERMs 91.66% and 92.85%, respectively) and diffuse retinal thickening (62.50% and 64.28%). These four cases had common characteristics to those with broad vitreal attachment regarding associated maculopathies and visual function. High correlation was seen between V-shaped and focal-VMT and between J-shaped and broad-VMT (kappa=0.850 P<0.001), except in four cases with broad adhesion despite the presence of a V-shaped pattern. Methodsįifty-three eyes with VMT syndrome were categorized into two classifications based on optical coherence tomography images: the VMT morphology (V- or J-shaped) and the diameter of adhesion (focal≤1500 μm or broad>1500 μm).
The aim of this study is to analyze the agreement between the classifications based on morphology and diameter of vitreomacular traction (VMT) syndrome, as well as to correlate the morphological findings of VMT with specific maculopathies.
