In this condition, there is a slow diminution of vision of the eyes. This occurs because the pumping action of the cornea or the front circular portion of the eye is not effective. Due to this the water content in the cornea keeps increasing. The endothelium or the back layer of the cornea is unable to prevent overhydration of the cornea. Due to this, there is haziness in the cornea, the cornea swells up and small blisters start occurring in the cornea in the front.
