Normal Measurements of Optic Nerve in Pediatric Population

Archives of Basic and Clinical Research
Objective: The aim of this study was to examine the normal values of the optic nerve in different segments of the nerve trace in the pediatric population using magnetic resonance imaging (MRI). Methods: Two radiologists retrospectively reviewed images

Zebrafish Slit2 and Slit3 Act Together to Regulate Retinal Axon Crossing at the Midline

Journal of Developmental Biology, 2022
Slit-Robo signaling regulates midline crossing of commissural axons in different systems. In zebrafish, all retinofugal axons cross at the optic chiasm to innervate the contralateral tectum.

Atrophy of the optic chiasm is associated with microvascular diabetic complications in type 1 diabetes

Frontiers in Endocrinology, 2023
IntroductionDiabetic neuropathy and diabetic eye disease are well known complications of type 1 diabetes. We hypothesized that chronic hyperglycemia also damages the optic tract, which can be measured using routine magnetic resonance imaging. Our aim was

Bilateral metastasis to optic nerve head – Interesting case report series

TNOA Journal of Ophthalmic Science and Research, 2021
Most intraocular metastatic tumors occur in the uveal tract, while isolated metastasis to the optic nerve is rarely found. Breast and lung cancers are the tumor types metastasizing to the eye most frequently; however, metastases of prostate cancer ...

Expression of inducible heat shock proteins Hsp27 and Hsp70 in the visual pathway of rats subjected to various models of retinal ganglion cell injury. [PDF]

PLoS ONE, 2014
Inducible heat shock proteins (Hsps) are upregulated in the central nervous system in response to a wide variety of injuries. Surprisingly, however, no coherent picture has emerged regarding the magnitude, duration and cellular distribution of inducible ...

Diffusivity and quantitative T1 profile of human visual white matter tracts after retinal ganglion cell damage

NeuroImage: Clinical, 2019
In patients with retinal ganglion cell diseases, recent diffusion tensor imaging (DTI) studies have revealed structural abnormalities in visual white matter tracts such as the optic tract, and optic radiation. However, the microstructural origin of these
