Abstract :

Purpose: To investigate structure of vitreomacular traction (VMT), specifically, if a correlation exists between 1) the VMT type/grade and the central foveal thickness (CFT) and subfoveal and adjacent choroidal thickness, 2) the vitreomacular/foveal angle (VMFA) and the CFT and subfoveal and adjacent choroidal thickness, and 3) the diameter of vitreomacular adhesion (VMA) and CFT and subfoveal and adjacent choroidal thickness. Materials & Methods: Retrospective, multicenter image analysis study. We analyzed raster scans of the macula taken with spectraldomain optical coherence tomography (SD-OCT) of 61 eyes of 55 patients with VMT. Conventional scans of the vitreoretinal interface were analyzed to measure CFT and degree of VMFA. Enhanced depth imaging (EDI) scans were analyzed to measure choroidal thickness in the macula. Multivariate test of means and t-test were used to statistical comparisons. Results: There was no statistically significant difference in CFT between focal vs. broad and concurrent vs. isolated type VMT. Central (p=0.009), nasal (p=0.004) and temporal (p=0.007) subfoveal choroidal thickness was significantly higher in broad VMT compared to focal VMT. There was difference in both CFT (p=0.035) and central (p=0.005), nasal (p=0.01) and temporal (p=0.001) choroidal thickness between moderate vs. severe VMT. There was correlation between VMFA and CFT, where a wider angle was associated with increased CFT (p=0.026). The broader VMA was associated with increased central subfoveal (p=0.032), nasal (p=0.05) and temporal (p=0.01) choroidal thickness. Conclusions: Eyes with broad VMT have thicker choroid than eyes with focal VMT, which have a more open vitreomacular angle.
