MKSAP: 65-year-old woman with prodrome of pain on the tip of the nose

Test your medicine knowledge with the MKSAP challenge, in partnership with the American College of Physicians.

A 65-year-old woman is evaluated for a prodrome of pain on tip of the nose followed by a painful eruption involving the right periorbital tissue.

On physical examination, all vital signs are normal. There are grouped vesicles on an erythematous base on the tip of the nose and about the right eye.

Which of the following is the most appropriate first step in management of this patient?

A) Apply warm compresses
B) Begin ophthalmic corticosteroids
C) Begin valacyclovir and obtain urgent ophthalmology consultation
D) Obtain bacterial culture and start cephalexin

MKSAP Answer and Critique

The correct answer is C: Begin valacyclovir and obtain urgent ophthalmology consultation.

This patient has herpes zoster ophthalmicus (shingles), and referral to an ophthalmologist and empiric treatment with an antiviral agent (acyclovir, valacyclovir, or famciclovir) are imperative. Ophthalmic zoster, if not treated promptly, can lead to blindness. Shingles, which is reactivation of varicella-zoster virus, can occur anytime after the primary varicella infection. It often begins with a prodrome of intense pain, and in more than 90% of patients, it is associated with pruritus, tingling, tenderness, or hyperesthesia. The cutaneous eruption typically involves a single dermatome and rarely crosses the midline. In a recent, prospective multicenter study, eye redness and rash in the supratrochlear nerve distribution had a statistically significant association with clinically relevant eye disease. One hundred percent of patients who developed moderate to severe eye disease presented with a red eye. Hutchinson sign (zoster eruption on the tip of the nose) was not predictive of clinically relevant eye disease. Clinical diagnosis is based on both history and physical examination. Testing by direct fluorescent-antibody testing or by polymerase chain reaction can confirm the diagnosis; however, decisions regarding antiviral therapy are often based on history and physical examination rather than reliance on laboratory testing.

Applying warm compresses or obtaining bacterial culture and starting antibiotics would not be appropriate treatment for a viral infection, and delaying treatment could result in blindness. Ophthalmic corticosteroids are frequently administered as an adjunctive agent to antiviral therapy in the treatment of ophthalmic zoster but are never used as a single agent and should be administered by a specialist.

Key Point

  • Ophthalmic herpes zoster infection should be considered a medical emergency that requires prompt referral to an ophthalmologist and initiation of an antiviral agent.

    I felt like I wanted to die when my doctor confirmed that I have herpes. After my bf left me, I couldn’t bring myself to go on normal dates again. Because I was ashamed to tell anyone that I have herpes.

    I have wasted so much money on medication that couldn’t really fix my problem. Worse, I was losing a lot of hair and I was constantly exhausted. Almost lost my job!

    In my desperation, I have tried many drugs and alternative methods. You name it, I’ve tried it. I just would not give up!

    After many failed attempts, I have been free of outbreaks for 6 months and 2 weeks without taking any medication. I have finally found a method that works for me!

    So if you’re down and out, JUST KEEP TRYING until you find something that works. If anyone cares to hear what I’ve tried and what I have been doing. Then I’d be happy to help in any way.

    Just reach out to me at michelleyunjc[at]gmail[dot]com and I will share more details about my experiences.

    I wish someone would have helped me out when I was struggling to find a solution. So if I can help you then it would make my day.
