We report a case of a 31 year-old man who presented a bilateral ischemic optic neuropathy associated with headaches and severe systemic hypertension. This episode appeared after administration of ergotamine tartrate and macrolides. This medication probably led to a vasospasm which occurs in patients with hypertension. The cardiovascular and serum lipid evaluations were normal. A migraine optic neuropathy can be evoked.

Purpose: A relative afferent pupillary defect (RAPD) is a characteristic clinical sign of optic neuritis (ON). Here, we systematically evaluated ultrasound pupillometry (UP) for the detection of an RAPD in patients with ON, including a comparison with infrared video pupillometry (IVP), the gold standard for objective pupillometry.
Materials And Methods: We enrolled 40 patients with acute (n = 9) or past (n = 31) ON (ON+), 31 patients with multiple sclerosis (MS) without prior ON, and 50 healthy controls (HC) in a cross-sectional observational study.

Background: Hyperreflective retinal foci (HRF) visualized by optical coherence tomography (OCT) potentially represent clusters of microglia. We compared HRF frequencies and their association with retinal neurodegeneration between people with clinically isolated syndrome (pwCIS), multiple sclerosis (pwMS), aquaporin 4-IgG positive neuromyelitis optica spectrum disorder (pwNMOSD), and healthy controls (HC)-as well as between eyes with (ONeyes) and without a history of optic neuritis (ONeyes).
Methods: Cross-sectional data of pwCIS, pwMS, and pwNMOSD with previous ON and HC were acquired at Charité-Universitätsmedizin Berlin.

Some patients with neuromyelitis optica spectrum disorder (NMOSD)-like symptoms test negative for anti-aquaporin-4 (anti-AQP4) antibodies. Among them, a subset has antibodies targeting myelin oligodendrocyte glycoprotein (MOG), a condition now termed MOG antibody-associated disease (MOGAD). MOGAD shares features with NMOSD, like optic neuritis and myelitis, but differs in pathophysiology, clinical presentation, imaging findings, and biomarkers.

Purpose: To retrospectively evaluate the efficacy of plaque brachytherapy for the treatment of retinoblastoma.
Methods: We retrospectively reviewed the clinical records of 163 patients (186 eyes, 333 tumors) treated with brachytherapy (Ru or Sr plaques) for intraocular retinoblastoma between November 2007 and August 2023.
Results: Complete tumor control was achieved in 273 tumors (82%).

Failure of central nervous system (CNS) axons to regenerate after injury results in permanent disability. Several molecular neuro-protective and neuro-regenerative strategies have been proposed as potential treatments but do not provide the directional cues needed to direct target-specific axon regeneration. Here, we demonstrate that applying an external guidance cue in the form of electric field stimulation to adult rats after optic nerve crush injury was effective at directing long-distance, target-specific retinal ganglion cell (RGC) axon regeneration to native targets in the diencephalon.
