Assessing retinal and choroidal thickness changes in vitreomacular traction syndrome using enhanced depth imaging optical coherence tomography.

Aim: To evaluate effect of different types and stages of Vitreomacular Traction (VMT) on morphology of retina and choroid using spectral domain optical coherence tomography (SD- OCT) utilizing Enhanced Depth Imaging (EDI).

Methods: Observational cross sectional analytic study. Conventional SD-OCT scans were analyzed to measure Central Foveal Thickness (CFT), Vitreomacular Adhesion (VMA) area and grade, VMT Angle (VMTA) and posterior hyaloid thickness. EDI scans were analyzed to measure choroidal thickness. Main outcome measures: Average choroidal thickness, comparing mean CFT and average choroidal thickness between different VMT groups and grades, and correlating each of mean CFT and average choroidal thickness on one hand and average VMTA, VMA area and posterior hyaloid thickness on the other.

Results: The study included 104 eyes (104 patients). There was statistically significant difference in CFT between concurrent vs. isolated VMT. Choroidal thickness was significantly higher in concurrent compared to isolated VMT. There was correlation between VMTA and CFT, where wider angle was associated with increased CFT. Broader VMA was associated with increased choroidal thickness.

Conclusion: VMT independent of macula and fovea, influences choroidal structure. Angle of vitreous adhesion is important in determining changes at vitreoretinal interface. These observations need to be further investigated in prospective longitudinal studies.
