Treating Eye Problems
The varicella-zoster virus may travel to the head and neck, perhaps involving an eye, part of the nose, cheek, and forehead. In about 40 percent of those with shingles in these areas, the virus infects the cornea. Pain, numbness, and pressure in the eye are indicators of a condition called herpes zoster ophthalmicus, and severe damage or scarring can result.
Doctors will often prescribe oral antiviral treatment to reduce the risk of the virus infecting cells deep within the tissue, which could inflame and scar the cornea. The disease may also cause decreased corneal sensitivity, meaning that foreign matter, such as eyelashes, in the eye are not felt as keenly. For many, this decreased sensitivity will be permanent.
It's important that people who have had facial shingles schedule follow-up eye examinations because corneal problems may arise months after the facial condition is gone.
