Health: With herpes on the tip of the nose go immediately to the doctor
Thank you for your evaluation!
Who has been infected with chicken pox as a child, carries the varicella zoster virus itself. You can come back later than the shingles, but also attack the eyes. Even at the first sign of this, patients must go to the doctor quickly.
If anyone notices unusual pimples on the tip of his nose, he should immediately see a doctor. This could be what is called the Hutchinson sign, which indicates a recurrence – that is, the recurrence of an infection – with the chickenpox virus.
The problem: these viruses can attack the eye and cause lasting damage. the Department of Ophthalmology of the University Medical Center of Friborg. Just like the more familiar herpes simplex viruses that cause clbadic cold sores, chickenpox and shingles viruses also retract into the nervous system after a chicken pox infection. There, they wait until the immune system of the affected person is so weak that they can attack again.
If the ganglia virus – called ganglions – are established in the vicinity of the spinal cord, they cause shingles in case of recurrence. "If, on the other hand, they are found in the ganglia in the brain, eye infestation is possible," says Reinhard. The first sign of this is usually a change of skin on the tip of the nose.

Patients bearing the Hutchinson mark go to the dermatologist if they are actively approaching him for possible ocular involvement, advises Reinhard. Because only if the infection is also treated ophthalmologically early, permanent damage can be prevented. "We usually take patients to hospital and administer high-dose antivirals intravenously," says the specialist. These drugs are said to suppress viruses.
And if not treated in time? According to Reinhard, sufferers end up noticing a disorder in their field of vision. "In the cornea, white patches may be visible." These are not the viruses, but the white blood cells that fight against the infection. "At this point you can only prevent the defense reaction," says Reinhard – about eye drops containing cortisone, and permanently. Otherwise, the patient threatens to be blind.
