The physiological process in which the stroma of the cornea is kept relatively dehydrated to maintain normal corneal clarity and transparency


Deturgescence is essential to prevent excessive hydration of cornea from an influx of cations and water molecules into the corneal stroma. This causes the cornea to swell (corneal edema), which in turn could result in progressive corneal opacity or cloudiness. Without an efficient deturgescenct mechanism, this could lead to functional blindness. Deturgescence is therefore essential to maintain a clear, transparent cornea by relative corneal dehydration. This is done through the action of the impermeable epithelium as well as through the metabolic transport system in the endothelium.

Word origin: Latin de- (from) + turgesco (to begin to swell)
