These are photographs of the eyes of a 32 year old patient with herpes simplex disciform keratitis. The photo below is of the normal left cornea.
The picture below shows the diseased right cornea with stain. There are bright dots associated with damage to surface corneal cells. There are darker spots corresponding to individual surface cells that are swollen.
The picture below is the diseased right eye showing extreme swelling of the cornea. The lines are folds on the back surface of the cornea that occur when the cornea becomes swollen. The cornea is thick (about 689nm thick compared to the normal left eye of 499nm). A swollen cornea also begins to become cloudy.
I started this patient on aggressive topical antiviral and anti-inflammatory medication, which she’ll need to be on for at least a month before I taper the dosage down.
