TEACHING NEUROIMAGES: PSEUDO-OPTIC DISC EDEMA FROM VITREOPAPILLARY TRACTION STEPHANIE N. KLETKE, MD, AND JONATHAN A. MICIELI, MD, CM NEUROLOGY 2019;93:E317 COR...RESPONDENCE DR. MICIELI: [email protected] A 44-year-old asymptomatic man was noted to have a change in the appearance of his right Optic nerve on a routine follow-up. Visual function was normal and there was no relative afferent Pupillary defect. Optic disc margins were blurred and there was obscuration of the peripapillary Retinal vessels in the right eye (figure, a). Optical coherence tomography (oct) confirmed the Diagnosis of vitreopapillary traction (figure, b) creating a pseudo-optic disc edema appearance. FIGURE VITREOPAPILLARY TRACTION DEMONSTRATED WITH OPTICAL COHERENCE TOMOGRAPHY (A) Color photograph of the right optic nerve with areas of obscuration of the retinal vessels (white arrows). (B) Optical coherence tomography sections through the optic nerve superiorly (top) to inferiorly (bottom) confirm the diagnosis of vitreopapillary traction. The hyaloid face of the vitreous is indicated by the red arrows and the optic nerve substance is indicated by the yellow arrows.

El #nervio óptico es el II de los pares #craneales. Un tracto de fibras con aproximadamente 1,2 millones de #axones, rodeado por vainas #meníngeas, que transp...orta las sensaciones #visuales al sistema #nervioso #central. Está formado por los axones de las células #ganglionares y por #glía. Se desprende del globo #ocular 3 mm medialmente y 1 mm inferiormente al polo posterior del mismo. Se dirige posteromedialmente, atraviesa la cavidad craneal y termina en el ángulo anterolateral correspondiente del #quiasma #óptico. Su longitud total es de unos 5 cm. See more
