Abstract: Purpose 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.Methods Fifty-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 mu m or broad >1500 mu m).Results 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. These four cases had common characteristics to those with broad vitreal attachment regarding associated maculopathies and visual function. 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%). 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).Conclusions Although 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. 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.
