The extraocular muscle palsies associated with herpes zoster ophthalmicus (HZO) are transient, self-limiting conditions, usually seen in elderly patients. There are different treatment recommendations for paralytic complications, but prognosis has generally reported to be favorable. A 75-year-old male patient presented with diplopia. Clinical history revealed left facial vesicular eruptions and pain treated by oral aciclovir 1 week following symptom onset. On examination, we observed cicatricial lesions with crusts involving left hemiface, a limitation in abduction of the left eye, and a superficial punctuate keratitis (SPK) with decreased visual acuity (4/10). Examination of the right eye was unremarkable. Hess screen test confirmed left six nerve palsy.
