Abstract
PURPOSE: The primary objective of this study was to determine the prevalence of vitreomacular interface (VMI) changes on optical coherence tomography (OCT) in the general population. Second, other OCT changes were described. METHODS: Abnormalities in the VMI were diagnosed by OCT scan and graded according to the International Vitreomacular Traction Study (IVTS) Group classification and subdivided into 3 grades according to John et al. [Retina 2014;34:442-446]. RESULTS: The estimated prevalence of vitreomacular abnormalities within a Belgian population aged ≥50 years was 1.17% [confidence interval (CI 0.38-3.62)] for focal vitreomacular traction (VMT) grade 1; 0.39% (CI 0.05-2.76) for focal VMT grade 2; 8.17% (CI 5.33-12.53) for focal vitreomacular adhesion, and 17.9% (CI 13.41-23.9) for broad vitreomacular adhesion. CONCLUSION: The prevalence of vitreomacular abnormalities within a Belgian study cohort was reported. These results closely match previously reported data on the prevalence of VMT. Correct knowledge of the epidemiology of VMI disorders and early diagnosis will enable adequate intervention.
