Herpes zoster ophthalmicus is a viral infection caused by the varicella-zoster virus, affecting the ophthalmic branch of the trigeminal nerve, called the ophthalmic nerve. Herpes zoster ophthalmicus is characterized by a painful rash and blisters on one side of the forehead and around the eye, along with symptoms such as eye redness, tearing, and sensitivity to light, and can also lead to serious complications, such as corneal ulcers, glaucoma, and vision loss, particularly if the eye is involved. Herpes zoster myositis and oculomotor nerve involvement are rare complications of herpes zoster infection. Early diagnosis and treatment, such as antiviral medications, corticosteroids, and pain management, are important to prevent complications and to alleviate symptoms. In our case report we demonstrate the case of an 81-year-old female patient with left sided herpes zoster ophthalmicus, associated with MRI proved orbital myositis and oculomotor nerve involvement. Symptoms were slowly reduced with antiviral therapy. People who develop symptoms of herpes zoster ophthalmicus should seek prompt medical attention to receive appropriate care and to avoid serious complications.  Kulcsszavak: herpes zoster, herpes zoster ophthalmicus, oculomotor nerve, postherpetic neuralgia, magnetic resonance imaging
