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 ...

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 ...

The purpose was to investigate an objective and quantitative method to estimate the redness of the optic disc neuroretinal rim, and to determine the usefulness of this method to differentiate compressive optic neuropathy (CON) from glaucomatous optic neuropathy (GON).In our study there were 126 eyes: 40 with CON, 40 with normal tension glaucoma (NTG ...

Compressive optic neuropathy. Not everything that progresses is glaucoma
Archivos de la Sociedad Española de Oftalmología (English Edition), 2021Three clinical cases are presented of compressive optic neuropathy secondary to meningiomas of different locations, initially diagnosed with normal tension glaucoma (NTG). All patients were middle-aged women, with optic disc excavation, as well as asymmetric, rapidly progressive defects in the visual field (VF), and deterioration of the visual acuity ...

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 ...

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.

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.

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.

Compressive Optic Neuropathy Secondary to Chronic Sinusitis
Optometry and Vision Science, 1988ABSTRACT The 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.
