2.1.1
The corneal endothelium is a single layer of cells comprising the cornea's innermost layer. It helps maintain corneal transparency by removing excess fluid. Endothelial dysfunction leads to corneal clouding, resulting in visual impairment. Common causes of corneal endothelial dysfunction are Fuchs' dystrophy (a genetic disorder) and degeneration (bullous keratopathy). Other causes are trauma, infection and iatrogenic damage.
