Endoscopic optic canal decompression for compressive optic neuropathy
Journal of Clinical Neuroscience, 2011Compressive optic neuropathy is a rare condition that may be caused by trauma or non-traumatic events. Endoscopic techniques have evolved to provide an easier surgical approach to decompression. The aim of this study was to determine the endoscopic anatomy of the orbital apex and to identify the optimal targets for endoscopic optic nerve decompression.

Compressive optic neuropathy occurs when an extrinsic force acts upon the optic nerve. Compression may be secondary to inflammatory, infectious, vascular, traumatic, or neoplastic lesions. Mass effect on the optic nerve compromises optic nerve axoplasmic and blood flow, leading to decreased color vision and visual acuity, visual field defects, and ...

Compressive Optic Neuropathy Secondary to Chronic Sinusitis
Optometry and Vision Science, 1988The paranasal sinuses surround the orbit on three sides. The thin bony walls of the sinuses are an ineffective barrier to the spread of infection to either the orbit or the intracranial cavity. In this report a case of compressive optic neuropathy secondary to chronic sinusitis is presented.

Etiology and diagnostics of compressive optic neuropathies
Vestnik oftal'mologii, 2018To determine the causes and study the clinical manifestations of compressive optic neuropathy (CON).The study included 24 male and 36 female patients with CON (in total 60 patients, 97 eyes). All patients underwent standard ophthalmic examination, as well as computer perimetry, magnetic resonance imaging (MRI), and/or computed tomography (CT) of the ...

Compressive Optic Neuropathy Presenting With Psychiatric Symptoms
Journal of Craniofacial Surgery, 2014We report a case of bilateral optic neuropathy presenting with psychiatric symptoms. A 50-year-old woman was admitted with blurry vision in both eyes. She had a 3 months' history of depressed mood. Both optic discs had mild temporal pallor with visible spontaneous venous pulsations.

Optic nerve compression results in progressive, and often painless, monocular vision loss. In this chapter, we review the clinical signs and common causes of compressive optic neuropathy. We discuss in more detail the imaging characteristics and management of optic nerve sheath meningioma.

Optic nerve compression results in progressive, and often painless, vision loss. In this chapter, we begin by reviewing the clinical features of anterior and posterior compressive optic neuropathy. We next review the common causes of compressive optic neuropathy, which include orbital tumors (e.g., optic nerve sheath meningioma, optic glioma, and ...

Quantitative Perimetry in Compressive Optic Neuropathy and Optic Neuritis
Archives of Ophthalmology, 1978The Goldmann perimetric defects in 20 cases of compressive optic neuropathy and 54 cases of optic neuritis were analyzed. While defects involving the papillomacular bundle were the rule in both compressive and neuritis cases, sparing of the fixational area occurred in 24% of neuritis eyes but in none of the eyes with compressive neuropathy.

Anterior Temporal Chordoid Meningioma Causing Compressive Optic Neuropathy
Optometry and Vision Science, 2011Optic neuropathy associated with proptosis and ocular motility restrictions is suggestive of a compressive etiology. This raises concern for a mass lesion involving the orbit or orbital apex. Meningiomas, which account for 4% of all intraorbital tumors and 20 to 30% of all intracranial tumors, are capable of compressing critical anatomic structures ...

Compressive optic neuropathy caused by renal osteodystrophy
Journal of Neurosurgery, 2001✓ Compressive optic neuropathy with acute or chronic vision loss has been associated with various skull base tumors, aneurysms, Graves disease, trauma, and, less commonly, fibrous dysplasia and osteopetrosis. The authors present a case of acute visual deterioration in a 25-year-old woman who had massive calvarial hypertrophy with optic canal stenosis ...
