Müller cell cone, an overlooked part of the anatomy of the fovea centralis: hypotheses concerning its role in the pathogenesis of macular hole and foveomacualr retinoschisis.

Poorly recognized by anatomists and pathologists is the cone-shaped zone of Müller cells that composes the central and inner part of the fovea centralis. The importance of these cells in the structural integrity of the macula, as a repository for xanthophyll, and in the pathogenesis of macular diseases, particularly regarding idiopathic macular hole and foveomacular schisis, is hypothesized.
