The local expression of tuberculous meningitis has an high incidence. They respond to a Koch bacillus direct lesion or vasculitis disease. The clinic implication of ocular movement is frequent and usually answers to a nervous trunk direct injury. Exceptionally the clinic expression of the oculomotor disturbance is due to a conjugate ocular tract or nucleus damage. The posterior internuclear ophthalmoplegia is a well-known manifestation and correspond with a dwindle of the medial longitudinal fasciculus electrical transmission and lies in falling of the medial rectus to move synchronously with the contralateral rectus on attempted lateral gaze to either side. In such a case the medial longitudinal fasciculus is damaged between the sith nerve nucleous below and the opposite third nerve nucleus above. A patient with AIDS B3 category who presents right internuclear ophthalmoplegia and right eye vertical conjugate gaze impairment with left vertical nystagmus due to a paramedial mesencephalic stroke as debut of a linfocitary subacute meningitis is present.

Progressive supranuclear palsy (PSP) is a rare neurodegenerative disorder characterized by physical, cognitive, and behavioral impairments. The PSP Rating Scale (PSPRS) is a widely used and validated, clinical scale to monitor disease progression. Here we show the modification of PSPRS to improve clinical meaningfulness and sensitivity.

Purpose: Our study presents a virtual reality-based tangent screen test (VTS) to measure subjective ocular deviations including torsion in nine directions of gaze. The test was compared to the analogous Harms tangent screen test (HTS).
Methods: We used an Oculus Go controller and head-mounted-display with rotation sensors to measure patient's head orientation for the VTS.

Department of Ophthalmology, Rochdale Infirmary, Rochdale, UK.
Sweet syndrome (SS), or acute febrile neutrophilic dermatosis, is a dermatologic, auto-inflammatory disorder of unclear origin, often accompanied by systemic inflammation affecting various tissues, including the eyes. Common ocular manifestations include conjunctivitis but can extend to other ocular tissues. Orbital apex syndrome (OAS) involves damage to several cranial nerves transversing the orbital apex, leading to ophthalmoplegia and vision loss.

Idiopathic intracranial hypertension (IIH) is marked by increased intracranial pressure without any accompanying evidence of clinical, imaging or laboratory findings of intracranial pathology. In addition to headache, nausea and vomiting, typical symptoms might also include diplopia, photophobia and blurred vision. Third nerve palsy is rarely linked to IIH, although sixth nerve palsy is reported in the majority of individuals with IIH.

Anti-dipeptidyl-peptidase-like protein 6 antibody-mediated disease is a rare autoimmune encephalitis typically presenting with diarrhoea and/or weight loss, central nervous system hyperexcitability and cognitive dysfunction. We present a case of a young woman with 10 days of diplopia and unsteadiness in the context of dysthymia and significant weight loss over 2 months. Initial examination demonstrated mixed dysconjugate nystagmus and ataxic gait.
