Abstract:
A 74-year-old man had reproducible superior and inferior arcuate visual field defects in the left eye only that were initially believed to be caused by primary open-angle glaucoma. Diagnostic evaluation with the aid of optical coherence tomography revealed extrafoveal vitreomacular traction (VMT) with secondary retinal thickening and schisis. We discuss the evaluation of non-glaucomatous visual field defects and review the literature on the pathogenesis, clinical manifestations, and treatment of VMT syndrome.
