An Unnamed Human Oral sp. as the Cause of an Unusual Bacterial Keratitis.

We report a case of bacterial keratitis secondary to an undescribed sp. spp. are not easily cultured, and many reports have identified unculturable isolates through broad-range bacterial polymerase chain reaction (PCR).

The soil and the seed: The relationship between Descemet's membrane and the corneal endothelium.

Descemet's membrane (DM), the basement membrane of the corneal endothelium, is formed from the extracellular matrix (ECM) secreted by corneal endothelial cells. The ECM supports the growth and function of the corneal endothelial cells. Changes to DM are central to the diagnosis of the most common corneal endothelial disease, Fuchs endothelial corneal dystrophy (FECD).
