Bedside ocular ultrasonography for diagnosing increased intracranial pressure in patients with leptomeningeal metastases from non‐small‐cell lung cancer

Cancer Medicine, 2023
Objectives To explore the diagnostic accuracy of ultrasound measurement of optic nerve sheath diameter (ONSD) and optic disc height (ODH) in detecting intracranial hypertension in non‐small‐cell lung cancer (NSCLC) patients with leptomeningeal metastases

Sonographic Measurement of the Optic Nerve Sheath Diameter (ONSD) and Eyeball Transversal Diameter (ETD) in Benin Healthy African Adults

Open Journal of Radiology, 2020
Background: Measuring optic nerve sheath diameter (ONSD), a relatively re-cent technique, allows an indirect and non-invasive diagnosis of intracranial hypertension. The ONSD ratio to eyeball transverse diameter (ETD) increases this reliability of the technique.

A 28-mm intraocular foreign body removal: The vitreoretinal surgeon's dilemma

Indian Journal of Ophthalmology, 2022
Background: Intraocular foreign body (IOFB) removal becomes tricky if its large and impacted in the ocular coats. When confronted with such a combination, the vitreoretinal surgeon will need to modify the surgical plan.

Estimating Interpupillary Distance from Eyeball Size [PDF]

, 2022
The interpupillary distance (IPD) of a user’s face is used to frame prescription or non-prescription glasses, or other eyewear. The requirement for an IPD measurement necessitates a physical visit to an optometrist, making online glass (or frame) orders ...

Signs of Intracranial Hypertension, Hypermobility, and Craniocervical Obstructions in Patients With Myalgic Encephalomyelitis/Chronic Fatigue Syndrome

Frontiers in Neurology, 2020
The pathophysiology of myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) is unknown. In this study, we test the hypothesis that hypermobility, signs of intracranial hypertension (IH), and craniocervical obstructions may be overrepresented in ...

Temporal Evolution of Optic Nerve Sheath Diameter/Eyeball Ratio on CT and MRI for Neurological Prognostication After Cardiac Arrest. [PDF]

J Clin Med
Background: Optic nerve sheath diameter (ONSD) and its ratio to eyeball transverse diameter (ETD; ONSD/ETD) are potential markers for elevated intracranial pressure in comatose survivors of out-of-hospital cardiac arrest (OHCA). However, their prognostic

Evaluation of Eyeball and Orbit in Relation to Gender and Age

, 2016
The orbital aperture is the entrance to the orbit in which most important visual structures such as the eyeball and the optic nerve are found. It is vital not only for the visual system but also for the evaluation and recognition of the face.
