Objective We set out to assess the dynamics of retinal injury after acute optic neuritis (ON) and their association with clinical visual outcomes. Methods Thirty‐one consecutive patients ON were prospectively analyzed over a 6‐month follow‐up period. Each month, we used optical coherence tomography (OCT) thickness peripapillary nerve fiber layer (pRNFL) segmented macular layers, as well high‐contrast acuity, low‐contrast acuity (LCVA), color (CVA), fields (VF). Results In this prospective...

Over the years, Meckel's cave pathologies have been judged off-limits because of high rates morbidity. Even though several studies defined various surgical routes with tolerable morbidity and mortality rates, controversies related to optimal avenue treat different categories cavernous sinus neoplasms persist. With unceasing energy cultivate minimally invasive neurosurgical approaches, endoscopic endonasal route has tested, approach effectively performed, provide a valid window these areas....

To assess the association of primary retinal inflammation, namely periphlebitis (RP) and microcystic macular edema, with clinical, brain, imaging biomarkers multiple sclerosis (MS) severity.One hundred patients MS underwent a neurologic ophthalmic examination, MRI, optical coherence tomography. Disability was assessed using Expanded Status Scale at baseline after 1-year follow-up. The normalized brain volume, normal-appearing gray matter T1 lesion volume were as radiologic disease severity....

Background: Colour vision assessment correlates with damage of the visual pathway and might be informative overall brain in multiple sclerosis (MS). Objective: The objective this paper is to investigate association between impaired colour disease severity. Methods: We performed neurological ophthalmic examinations, as well magnetic resonance imaging (MRI) optical coherence tomography (OCT) analyses, on 108 MS patients, both at baseline after a follow-up one year. was evaluated by Hardy, Rand...

Neuromyelitis optica spectrum disorder (NMOSD) is an inflammatory central nervous system disease that preferentially affects the optic nerve and spinal cord [Wingerchuk et al. 2015]. Up to 70% of patients with NMOSD have antibodies aquaporin-4 (AQP4-IgG). AQP4 expressed in astrocytes Muller cells eye. A subgroup AQP4-IgG-seronegative has myelin oligodendrocyte glycoprotein (MOG-IgG), neuritis (ON) relapses are also frequent these [Hoftberger 2015]. We hypothesize retinal injury may be...

Patients presenting with visual disturbances often require a neuroimaging approach. The spectrum of includes three main categories: vision impairment, ocular motility dysfunction, and abnormal pupillary response. Decreased is usually due to an eye abnormality. However, it can also be related other disorders affecting the pathway, from retina occipital lobe. Ocular dysfunction may follow cranial nerves responsible for movements (ie, oculomotor, trochlear, abducens nerves); any abnormality...

Multiple Sclerosis (MS) is an immune-mediated disease of the Central Nervous System with two major underlying etiopathogenic processes: inflammation and neurodegeneration. The latter determines prognosis this disease. MS main cause non-traumatic disability in middle-aged populations.

Visual recovery after optic neuritis (ON) used to be defined as good, although patients frequently complain of poor vision.We carried out a prospective study on 38 consecutive with acute ON followed monthly for 6 months and evaluated high- low-contrast visual acuity (HCVA LCVA, respectively), quality vision (National Eye Institute Function Questionnaire-25 (NEI-VFQ-25)), fields, retinal thickness by spectral domain optical coherence tomography (OCT).We found significant impaired LCVA color...

Orbital inflammatory disease (OID) includes all processes affecting the orbit. Although several aetiologies are recognised, a cause may not be elucidated. We describe 2 cases in which drugs (hyaluronidase and zoledronic acid) were of OID. In patients with clinical picture OID simulating an orbital cellulitis, recent drug history should considered as possible aetiology, treatment steroids or without biopsy after infection has been excluded.
