Part I: Ophthalmic Pathology
Chapter 6: Cornea
Highlights
-
The precise structure and normal function of each of the 5 layers of the cornea are essential for maintaining its transparency. Disruption of any of these layers may result in vision loss due to lack of corneal clarity.
-
Infectious keratitis can be due to a variety of organisms and may result in significant scarring, ulceration, and even perforation of the cornea.
-
Degeneration of corneal structures and stromal ectasias may be primary or may be secondary to other ocular conditions.
-
Corneal dystrophies are bilateral, typically progressive, inherited conditions that often interfere with visual function.
