Abstract:
Purpose:To present a case of oculomotor nerve atrophy complicated by herpes zoster ophthalmicus (HZO).Case summary: A 68-year-old man with a history of type 2 diabetes and dyslipidemia complained of diplopia and deviation in left eye. On examination, visual acuity was 20/25 in right eye and 20/20 in left eye. Prism and alternate cover tests revealed right exotropia and hypertropia in the primary position. Examination of ductions and versions showed limitation of adduction and depression in the right eye. On detailed history taking, we found that his symptoms started after suffering HZO on right side about 2 years ago. He was prescribed antiviral agents from a dermatology clinic and was told that all symptoms would improve after medication so he didn't undergo an ophthalmologic examination at that time. Magnetic resonance imaging confirmed that diffuse atrophy of oculomotor nerve in cistern along with atrophic changes of medial rectus and inferior rectus muscles in right eye. A diagnosis of strabismus complicated by HZO-induced oculomotor nerve atrophy was done.
Conclusions:Ophthalmoplegia secondary to HZO may not be self-limiting and have a poor prognosis resulting in cranial nerve atrophy. A detailed imaging investigation of extraocular muscle and cranial nerves along with thorough history taking are required for proper diagnosis and better prognosis.
