BACKGROUND The optic nerve is frequently injured in multiple sclerosis and neuromyelitis optica, resulting in visual dysfunction, which may be reflected by measures distant from the site of injury. OBJECTIVE To determine how retinal nerve fiber layer as a measure of axonal health, and macular volume as a measure of neuronal health are related to changes in myelin water fraction in the optic r...
G optic neuritis is still somewhat of a management puzzle for ophthalmologists despite two excellent studies in recent years, says Anthony C. Arnold, MD, Professor of Ophthalmology, Chief of the Division of Neuro-Ophthalmology, and Director of the Optic Neuropathy Center at the Jules Stein Eye Institute. “Whether to treat typical monosymptomatic optic neuritis with steroids or not has always be...
Here we report a case of optic neuritis in the setting of herpes zoster ophthalmicus (HZO) in a child. A six-year-old girl presented with HZO in the right eye. During the hospitalization, her visual acuity decreased. Fluorescein angiography (FAG) and optical coherence tomography revealed optic neuritis in the affected eye. Visual acuity improved with one month of treatment with acyclovir and st...
BACKGROUND AND PURPOSE Acute unilateral optic neuritis is associated with a thickening of the retrobulbar portion of the optic nerve as revealed by transorbital sonography, but no comparison has been made between nerve sheath diameter and optic nerve diameter in patients with acute optic neuritis versus healthy controls. We evaluated optic nerve sheath diameter and optic nerve diameter in patie...
Optic neuritis, a cause of sudden vision loss, often heralds the onset of multiple sclerosis (MS) within the next few years. It is important to distinguish optic neuritis from other types of optic neuropathy so that treatment can be started promptly, possibly delaying the onset of MS.
The authors describe an 11-year-old girl with systemic lupus erythematosus (SLE) who developed simultaneous bilateral acute optic neuritis. Severe initial visual loss followed by permanent visual deficit occurred in both eyes despite therapeutic intervention. Recurrence of optic neuritis in one eye caused the vision to deteriorate further. The most probable pathogenesis is occlusive vasculitis ...
The pattern electroretinogram obtained in patients affected by multiple sclerosis were compared with those in a normal population. The pattern electroretinogram amplitude in multiple sclerosis optic neuritis frequently appeared normal, but pattern electroretinogram amplitude abnormalities were found in patients suffering from recurrent multiple sclerosis optic neuritis. Pattern electroretinogra...
We report a case of right optic neuritis caused by Rathke's cleft cyst (RCC) in a young adult. A 15-year-old boy presented with reduced visual acuity in the right eye. He was diagnosed with optic neuritis in the right eye 4 years earlier at other clinics before he was referred to our department. During our one-year examinations, the cause of the reduced vision in his right eye could not be dete...
BACKGROUND Most patients with multiple sclerosis without previous optic neuritis have thinner retinal layers than healthy controls. We assessed the role of peripapillary retinal nerve fibre layer (pRNFL) thickness and macular volume in eyes with no history of optic neuritis as a biomarker of disability worsening in a cohort of patients with multiple sclerosis who had at least one eye without op...
Background: Multiple sclerosis and other demyelinating processes are sometimes difficult to differentiate from the neurological involvement in autoimmune diseases. Distinguishing multiple sclerosis from other lesions due to autoimmune diseases is crucial to avoid unsuitable or delayed treatments. Methods: Charts of 6 patients diagnosed with mimicking multiple sclerosis between 1996 and 2014 we...
