Immunoglobulin G4-related disease (IgG4-RD) is a systemic rheumatic disease characterized by the infiltration of IgG4-positive plasma cells and swelling or hypertrophic lesions in various organs. IgG4-RD also involves optic lesions, which is known as IgG4-related ophthalmic disease (IgG4-ROD). IgG4-ROD involves the surrounding tissues, causing optic neuropathy when it affects the optic nerve. Impairment of the optic nerve is often progressive, with delayed diagnosis and treatment leading to permanent visual loss. However, optic neuropathy due to IgG4-RD is rare and the visual prognosis is unclear. Herein, we present a case of long-standing optic neuropathy in IgG4-ROD with loss of light perception.

A boy in middle childhood with a history of early morning headaches presented to secondary care after being found to have bilateral papilloedema by his community optometrist. CT head showed a large right-sided heterogeneous calcific and haemorrhagic mass causing marked mass effect and midline shift. Preoperatively, the lesion was characterised on MRI as a haemorrhagic mass with a 'popcorn' appearance suggestive of a giant cavernous malformation measuring 6.

Background And Objectives: A simple, quick, and reproducible procedure for distinguishing multiple sclerosis (MS), myelin oligodendrocyte glycoprotein antibody-associated disease (MOGAD), and neuromyelitis optica spectrum disorder (NMOSD) at inaugural optic neuritis (ION) could be highly valuable in guiding early management.
Methods: We included all adults admitted to the MS center of Marseille for ION between March 2016 and April 2024, with CSF analysis including the kappa free light chain (K-FLC) index. Receiver operating characteristic curves were used to measure the diagnostic ability of the K-FLC index.
Gut microbiota regulates optic nerve fiber myelination.

Introduction: Recent evidence supports the hypothesis of an association between gut microbiota and the pathogenesis of retinal and eye diseases, suggesting the existence of a gut-eye axis. However, no data are available on the possible effect of the gut microbiota on the optic nerve fiber maturation and myelin development.
Methods: We investigated the impact of gut microbiota on the optic nerves collected from neonatal and young adult germ-free (GF), gnotobiotic (stably colonized with 12 bacteria strains, OMM12) and control (colonized with a complex gut microbiota, CGM) mice, by performing stereological and morphoquantitative analyses with transmission electron microscopy and gene expression analysis by quantitative real-time PCR.

Purpose: Primary epiretinal, or more precisely termed pre macular membranes (PMM) and glaucomatous optic neuropathy are both common conditions affecting a predominantly elderly population. There are several relevant clinical and pathological considerations when they are both diagnosed in the same eye.
Methods: We systematically searched the literature to review the challenges clinicians must address when dealing with patients with co-existing PMM and glaucoma.
