Radiological evolution and delayed resolution of an optic nerve tuberculoma: Challenges in diagnosis and treatment

Annals of Indian Academy of Neurology, 2013
Optic nerve tuberculomas are rarely reported and their natural history, prognosis, and duration of required treatment remain unclear. A 40-year-old immunocompetent male presented with complete loss of vision in his right eye, which had evolved over 6 ...

Quantitative Analysis of Optic Disc Cupping in Compressive Optic Neuropathy

Journal of Neuro-Ophthalmology, 1995
Cupping of the optic disc, a characteristic sign of glaucoma, has been anecdotally described in association with compressive optic neuropathy. The aim of this study is to perform a masked, controlled, and quantitative measurement of the optic disc cup to determine if compressive lesions of the afferent visual pathway were associated with increased ...

Transsphenoidal Optic Canal Decompression to Manage a Venous Malformation of the Optic Canal: A Case Report

Case Reports in Ophthalmology
Introduction: Intracanalicular vascular malformations are rare. This report describes a case of compressive optic neuropathy secondary to an intracanalicular venous malformation managed with endoscopic transsphenoidal optic canal decompression.

Clinical course of compressive optic neuropathy in skull-base tumors

Journal of Ophthalmology, 2020
Background: Skull-base tumors (SBTs) of the middle and anterior fossae typically cause mass effect on the optic nerve/chiasm complex. The most common of these neoplasms are pituitary adenomas, meningiomas and craniopharyngiomas.

Longitudinal visual functional recovery in compressive optic neuropathy in patients with primary pituitary microadenoma after endoscopic transnasal surgery

Journal of Ophthalmology, 2021
Background: Neoplasms of the chiasmal and optic nerve region can result in compressive optic neuropathy with reduced visual acuity (VA), visual field defects and primary descending optic atrophy.

Different damage patterns of retinal nerve fiber layer and ganglion cell-inner plexiform layer between early glaucoma and non-glaucomatous optic neuropathy [PDF]

International Journal of Ophthalmology, 2020
AIM: To compare the damage pattern of the peripapillary retinal nerve fiber layer (pRNFL) and the macular ganglion cell-inner plexiform layer (mGCIPL) between early glaucomatous and non-glaucomatous optic neuropathy (EGON and NGON).

Structural and functional differentiation between compressive and glaucomatous optic neuropathy

Scientific Reports, 2022
Clinical diagnoses of slow, progressive, painless visual losses with various degrees of visual field (VF) losses and disc atrophy are often confused between suprasellar compressive optic neuropathy (CON) and open-angle glaucomatous optic neuropathy (GON).
