Internal Carotid Artery Dissection Presenting with Transient or Subclinical Horner Syndrome.

Introduction: The most frequently encountered symptoms in internal carotid artery dissection (ICAD) are head or neck pain and cerebral ischemia. Ocular symptoms or signs have been reported as the presenting feature in up to 50% of patients, with (painful) Horner syndrome being the most frequently associated. Horner syndrome is part of the classic triad that depicts the characteristic presentation of ICAD and that consists of pain in the ipsilateral neck, head and orbital regions, (partial) Horner syndrome, and cerebral or retinal ischemia.

Focal Pachymeningitis Induced Papilloedema as an Early Manifestation of Relapsing Polychondritis.

A 52-year-old male patient presented with longstanding non-specific symptoms of ocular redness and irritation. Clinical examination not only revealed bilateral anterior scleritis but also bilateral optic disc swelling. Additional history taking revealed headaches and tinnitus, both starting around the same time as the eye redness, as well as a prior episode of swelling and redness of both ears.

Clinically relevant increases in serum neurofilament light chain and glial fibrillary acidic protein in patients with Susac syndrome.

Background And Purpose: Serum levels of neurofilament light chain (sNfL) and glial fibrillary acidic protein (sGFAP) are promising neuro-axonal damage and astrocytic activation biomarkers. Susac syndrome (SS) is an increasingly recognized neurological condition and biomarkers that can help assess and monitor disease evolution are highly needed for the adequate management of these patients. sNfL and sGFAP levels were evaluated in patients with SS and their clinical relevance in the relapse and remission phase of the disease was assessed.

Optic neuritis in lung adenocarcinoma: A challenging diagnosis.

Optic neuritis with CRMP-5 IgG is a paraneoplastic inflammation of the optic nerve associated with lung cancer, mostly small-cell lung cancer. We present the case of a patient with lung adenocarcinoma who developed progressive bilateral visual loss a few months after immune-chemotherapy with pembrolizumab and after Covid-19 vaccination. Positive CRMP-5 IgG were detected in blood sample and complete work-up - including brain MRI - did not show any progression.

Posterior segment spectral domain oct in the differential diagnosis of bilateral temporal optic neuropathy and its correlation with visual acuity.

Purpose: To identify the underlying etiologies and to evaluate the differential diagnostic value of posterior segment spectral domain OCT measurements and their correlation with best-corrected visual acuity (BCVA) in a group of patients with OCT documented bilateral optic neuropathy limited to the temporal quadrants.

Methods: Retrospective study.

Results: We included 61 patients: 35 presented with presumed "classic" acquired mitochondrial optic neuropathy (MON) (18 nutritional, 11 toxic, 6 mixed toxic-nutritional) and 2 with suspected hereditary MON.

Sarcoidosis revealed by simultaneous optic nerve and eyelid involvement: A case report.

Purpose: Ocular disease can be the initial manifestation in patients with sarcoidosis. It is most often associated with uveitis, but eyelid or optic nerve disease can also be presenting features. Although uncommon and easy to overlook in a patient presenting with visual loss, paying attention to the presence of eyelid granulomas in our patient proved to be very helpful in our diagnostic work up for optic neuropathy.

EVALUATION OF TUMOR NECROSIS FACTOR INHIBITOR THERAPY IN SUSAC SYNDROME.

Purpose: To evaluate the effect of tumor necrosis factor (TNF) inhibitor therapy on ocular relapses in patients with Susac syndrome.

Methods: Multicenter retrospective cohort study of patients diagnosed with Susac syndrome according to classical clinical criteria. We evaluated the disease activity before and after introduction of anti-TNF therapy and its value as a steroid-sparing agent.

Central retinal artery occlusion and Susac syndrome: a case report.

Background: Susac syndrome is a rare disease attributed to microangiopathy involving the arterioles of the brain, retina, and cochlea. Understanding the pathogenesis is incomplete, but an immune-mediated process remains the leading hypothesis.

Methods: Report of a single case of a previously healthy 22-year-old female patient showing the complete clinical triad.
