          Abstract

          Background

          Herpes zoster ophthalmicus (HZO) can involve the oculomotor nerve; however, isolated trochlear nerve palsy has rarely been reported.

          Case Report

          An 83-year-old man who suffered from HZO in the right frontal area and scalp subsequently developed vertical diplopia and severe pain. Cerebrospinal fluid examination and brain MRI revealed no abnormalities. Isolated right trochlear nerve palsy was diagnosed based on the findings of neuro-ophthalmological tests.

          Conclusions

          Isolated trochlear nerve involvement associated with HZO is very rare and may be easily overlooked. Physicians should carefully examine oculomotor involvement in HZO.

            External ocular motor palsies in ophthalmic zoster: a review.

            Seventy-seven new patients suffering from ophthalmic zoster and a selected group of 69 old patients were carefully examined with regard to external ocular movements. An incidence of 31% of ocular pareses was found in the new patients, and 58 in all were analysed. We were surprised to find several of these were contralateral and bilateral palsies. 28% of the palsies were asymptomatic, due to diplopia being present only in extremes of gaze and the rapid development of suppression in the affected eye. The theories of aetiology of these pareses are discussed.

              Complete ophthalmoplegia after zoster ophthalmicus.

              Complete ophthalmoplegia following herpes zoster ophthalmicus (HZO) is rare. We report three cases of HZO-associated complete ophthalmoplegia and review thirteen additional cases reported in the English language medical literature over the past 30 years. HZO-associated complete ophthalmoplegia occurs mostly in individuals over the age of 50 years and usually occurs within one to two weeks of the development of cutaneous HZO. The prognosis for recovery is good, with-significant improvement typically seen within 2 months and complete or near resolution within 18 months time.
