EPIDEMIOLOGY OF VITREOMACULAR INTERFACE ABNORMALITIES USING MACULAR SPECTRAL-DOMAIN OPTICAL COHERENCE TOMOGRAPHY IN...

The aim of this study was to investigate the prevalence of vitreomacular interface abnormalities (VMIAs) and to identify associated factors in an elderly population in Europe.

The MONTRACHET (Maculopathy Optic Nerve nuTRition neurovAsCular and HEarT diseases) Study is a population-based study, conducted in subjects older than 75 years. Vitreomacular adhesions, vitreomacular tractions, macular holes, epiretinal membranes, and macular cysts were assessed on spectral-domain optical coherence tomography examinations. The prevalence of VMIAs was estimated. We studied the association of demographic and clinical factors with VMIAs.

The mean age of the participants was 82.3 (SD, 3.8) years, and 37.3% were men. The prevalence rates of VMIAs were vitreomacular adhesions (17.7%), vitreomacular tractions (1.4%), lamellar macular holes (1.0%), full-thickness macular holes (0.2%), macular pseudoholes (0.4%), epiretinal membranes (38.9%), and macular cysts (5.8%). In multivariate analysis, vitreomacular adhesions were positively associated with male sex (P < 0.001) and negatively associated with older age (P < 0.001) and cataract extraction (P < 0.001). Epiretinal membranes were positively associated with older age (P < 0.001) and cataract extraction (P < 0.001).

The prevalence of VMIAs based on spectral-domain optical coherence tomography analysis was high in subjects older than 75 years.
