ABSTRACT Acute disseminated encephalomyelitis is a rare, acute, inflammatory, and demyelinating disease of the central nervous system. Presumably associated in more than three quarters of cases by infections (viral, bacterial, or nonspecific) and immunizations or without any identifiable antecedent. It usually presents a monophasic course with onset of nonspecific symptoms in the prodromal phase and may evolve with multifocal neurological changes and even visual acuity loss. We describe a case of a 9-year-old boy with an initial picture of papillary […]

We present a case of optic neuritis secondary to Chikungunya virus infection. Male, 46 yo, initial symptoms were pain and low visual acuity in the right eye associated to fever and symmetrical polyarthralgia one week ago. At the examination the visual acuity was 20/60 in the right eye and 20/20 in the left eye, fundoscopy showed papillo edema on the right eye. Immediately initiated pulse therapy with methylprednisolone for 7 days and improvement of the neuritis was observed in the […]

A 58-year-old woman presented with rash over the left side of the face and intense acute uveitis. Following careful review of the symptoms and dilated fundus examination unilateral optic neuritis was discovered. The rash was typical of varicella zoster dermatitis. Patients presenting with herpes zoster ophthalmicus should always undergo dilated fundus examination, as there is a potential risk of unexpected posterior segment inflammation. Early diagnosis and prompt treatment can avoid visual sequelae.

We described a 35 years old female patient with bilateral visual loss and pain on eye movement, mild papillary edema in acute phase, arcuate scotoma and complementary test positive for antinuclear antibodies that did not respond to corticosteroid therapy. The lack of clinical criteria for systemic lupus erythematosus (SLE) didn’t prevent the institution of the specific treatment with corticosteroids and azathioprine. After seven months the diagnosis was made after a skin manifestation of the disease. This case shows the value […]

Herpes Zoster ophthalmicus (HZO) is caused by a varicella-zoster virus infection which remains latent in the ganglion of Gasser until it is reactivated and compromise the ophthalmic division of the trigeminal nerve. HZO commonly causes neuro-ophthalmic complications such as vesicular lesions in the eyelids, keratoconjunctivitis, sclertis, uveitis, ocular palsy, orbital miositis and optic neuritis. HZO rarely presents as an orbital apex syndrome. This paper describes a patient with of orbital apex syndrome associate and meningitis caused by HZO which was […]
