Relationship between Vitreomacular traction width, foveal fl
A Study was conducted to investigate the relationship between vitreomacular traction (VMT) width, foveal floor width (FFW) and other anatomical characteristics between eyes of patients with VMT.

Retrospective observational study of unilateral and bilateral VMT cases was done. For unilateral VMT cases: VMT width in the affected eye and FFW in the non-affected fellow eye were measured. In bilateral VMT cases: VMT width in both eyes was measured. In all cases, the presence of any associated inner or outer retinal, and vitreoretinal interface (VRI) changes, including epiretinal membrane, was also documented.

88 patients fulfilled the study criteria: 57 having unilateral and 31 bilateral VMT. For unilateral VMT cases, log (VMT) width was significantly correlated with FFW (r = 0.347). Using stepwise linear regression, FFW and VRI changes were both significantly associated with VMT width with a R2 of 0.21. In bilateral VMT cases, there was strong positive correlation between log (VMT) width (r = 0.88), and the presence of any VRI (r = 0.90) or outer retinal changes (r = 0.50) between the two eyes.

Individual variations in foveal morphology as evaluated by the FFW, as well as the presence of vitreoretinal interface alterations, are linked to the degree of VMT width, according to these studies. In bilateral VMT, VMT width, VRI, and outer retinal alterations were likewise substantially associated between eyes, implying that individual patient characteristics, both hereditary and acquired, impact their existence and extent.
