The Prevalence of Vitreomacular Interface Pathology in a Spanish Tertiary Hospital.

PURPOSE: To determine the prevalence of vitreomacular interface (VMI) pathology, using spectral-domain optical coherence tomography (SD-OCT). METHODS: VMI status was classified into macular posterior vitreous detachment (PVD), focal vitreomacular adhesion (VMA; ≤1,500 µm), broad VMA (>1,500 µm), focal vitreomacular traction (VMT; ≤1,500 µm), broad VMT (>1,500 µm), full-thickness macular hole (FTMH) with the presence of VMT, and FTMH without the presence of VMT. RESULTS: A total of 1,976 eyes were included. A nonpathologic VMI was observed in 1,875 eyes (94.8%), including 1,050 (53.1%) with PVD, 120 (6.1%) with focal VMA and 705 (35.6%) with broad VMA. A pathologic state of the VMI was diagnosed in 101 eyes (5.1%). Thirty-three eyes (1.7%) were classified as focal VMT, 29 (1.4%) as broad VMT, 39 (1.9%) as FTMH, resulting in 6 small, 12 medium and 21 large FTMHs, six eyes had VMT associated to FTMH. CONCLUSIONS: Even in a tertiary care, retinal referral practice, VMI pathology is a relatively rare condition. There was a higher prevalence in a tertiary hospital study compared to population-based studies.
