This phenomenon can be observed frequently, for various reasons (including: Fuchs dystrophy, incorrect use of contact lenses, interventions for the removal of cataracts, intraocular hypertension, etc.).

Corneal edema involves a decrease in the natural transparency of the cornea, which results in an alteration of vision.

According to the amount of excess fluid, corneal edema therefore translates into manifestations of various entities, ranging from blurred vision and the perception of halos around lights, to the loss of visual acuity.

in particular, it involves the cells (keratocytes) of its central layer, that is, the stroma.

Corneal edema can be diffuse or localized, transient or permanent.
