Corneal Anatomy And Disease

Though smaller than an M&M, this is a crucial part of our visual system and many entities that disturb the cornea may result in sub-optimal vision. Our surgeon, Dr. Ahmed Nasrullah is fellowship trained in diagnosis and management of Corneal disease and surgery. Our surgeons are the premier corneal surgeons in Loudoun and Fairfax Counties, performing thousands of corneal surgeries each year. A brief description of the cornea and cornea disease can be found below.

Corneal Layers

Cataract Treatment

 

The corneal epithelium is the outermost layer of the cornea and is responsible for providing protection against injury and infection. The surface of the epithelium is very smooth and provides support for the tear film, which is what is irregular in patients with dry eyes. A Corneal Abrasion is a minor but very painful eye injury. When an abrasion occurs, the corneal epithelium is disrupted exposing underlying corneal nerves. However, the epithelial layer can heal in only a few hours making it one of the fastest healing parts of the body.

The corneal stroma makes up about 90% of the thickness of the cornea and is the bulk of the corneal tissue. It is clear and allows us a window to see out of the eye.

Descemet’s membrane is the scaffold that holds the endothelium in place. The endothelium contains the cells that pump fluid out of the cornea. FUCHS’ DYSTROPHY is a disease characterized by an unhealthy endothelium and, because these cells do not regenerate, this leads to swelling of the cornea and loss of clarity. DSAEK (Descemet’s Stripping Automated Endothelial Keratoplasty), is an advanced technique involving replacing only the back layers of the cornea, instead of full-thickness corneal transplant surgery.
