| Abstract |
|
Normally the cornea has a water content varying between 76-78%, a state of relative dehydration maintained through its own metabolism by the active transport of water and ions across its limiting membrane, the epithelium and endothelium. If the metabolism is grossly disturbed or if the effectivity of the limiting membrane is impaired, the living cornea will swell by the absorption of the fluid. Corneal edema are developed due to trauma, inflammation, glaucoma, degeneration, and neuropathic and metabolic conditions. Essential corneal edema are encountered for which no cause can be found, the condition apparantly occuring without other ocular pathology. A 29 years old Korean lady has been found to have bilateral essential edema of the cornea. |
