A woman developed headaches, transient visual obscurations, anosmia, and decreased visual acuity. Ocular examination showed bilateral pulsatile proptosis and disc edema with choroidal folds. Standardized ophthalmic echography showed absence of bony orbital roofs, prominent dural pulsations, direct apposition of brain parenchyma and orbital tissues, and echographic signs suggesting bilateral optic nerve compression. CT and MRI showed a large defect in the floor of the anterior cranial fossa. The cribriform plate, both orbital roofs, and sphenoid bones were displaced by a large basal encephalocele. Clinical improvement followed reconstruction of the anterior cranial fossa and decompression of both optic nerves.

Background: This study aims to assess the relationships between sphenoid sinus (SS) types, septation, lobulation, symmetry, septal deviation, and the variations in SS pneumatization regarding the surrounding neurovascular structures using Computed tomography (CT) images. Sexes and age groups were investigated.
Material And Methods: We retrospectively evaluated head CT-scans of 320 patients (age range 18-49 years); mean of 43.

CNS lymphoma is a rare form of non-Hodgkin lymphoma that primarily affects the brain, spinal cord, leptomeninges, or eyes, leading to severe neurological or ophthalmological complications. This case report details a 44-year-old male with human immunodeficiency virus and diffuse large B-cell lymphoma who experienced permanent vision loss due to optic perineuritis, a rare presenting symptom indicative of underlying CNS involvement. Despite previous remission, imaging revealed focal enhancements suggesting CNS lymphoma, highlighting diagnostic and management challenges in relapsed lymphoma, especially in immunocompromised patients.

Purpose Of Review: Intimate partner violence (IPV) is a leading cause of death and disability across the world. We sought to investigate the prevalence and clinical presentation of ocular injuries in IPV.
Recent Findings: Literature review revealed 16 published studies that evaluated ocular injuries in IPV, of which the study types included 9 retrospective studies, 2 prospective, 1 review, 1 invited commentary, 2 case reports, and 1 population-based cross-sectional survey.

Background: There are significant discrepancies in the optic nerve sheath diameter (ONSD) reported in the literature. We aimed to determine the ultrasonographic imaging features of ONSD and ophthalmic vessels in a healthy population, using a standardized protocol, and to estimate the effect of demographics and positioning changes on imaging measurements.
Methods: We measured the mean values of the ONSD in supine and sitting position and the Doppler imaging parameters of the ophthalmic, central retinal and short posterior ciliary arteries.

Traumatic optic neuropathy (TON) is a common cause of irreversible blindness following head injury. TON is characterized by axon damage in the optic nerve followed by retinal ganglion cell death in the days and weeks following injury. At present, no therapeutic or surgical approach has been found to offer any benefit beyond observation alone.
