Below is a photo of a young 12 year old who has a recurring lesion on his eyelid. It always occurs near the same location with yearly frequency. This is the same condition that causes cold sores (which he also gets) on the lips, only it’s a different branch of the trigeminal nerve that serves the face.
Herpes Simplex Virus is airborne as well as spread by body fluids. HSV 1 is the non-venereal version that most people harbor. The virus resides in the trigeminal ganglion, which is where the three branches of the trigeminal nerve meet. It only causes lesions in patients when it is triggered, usually during periods of stress, either physical or psychological. It is impossible to completely eradicate it, but lesions can be treated with anti-viral to prevent permanent tissue damage.
