As the disease progresses the sclera becomes denser than normal.
This permits the sclera to show through a very little at this part.
The eyes may remain open for such long periods of time that the conjunctiva and sclera may become quite dry and ulcerate.
In the stage of degeneration, ectasae of the sclera occur most frequently near the equator of the globe.
In acute glaucoma the sclera appears to be edematous and slightly thickened.
If the iris lies in contact with the sclera and cornea for some time, it becomes adherent (peripheral anterior synechia).
The displacement backward of the lamina cribrosa may cause that structure to lie behind the outer surface of the sclera.

n. pl. scle·ras or scle·rae (sklēr'ē)
The tough fibrous tunic forming the outer envelope of the eye and covering all of the eyeball except the cornea; the white of the eye. Also called sclerotic.
