Human proprioceptive gaze stabilization during passive body rotations underneath a fixed head.

Sci Rep

July 2024

Division of Eye and Vision, Department of Clinical Neuroscience, Marianne Bernadotte Centrum, St. Erik's Eye Hospital, Karolinska Institutet, Stockholm, Sweden.

The present study explored the presence of torsional gaze-stabilization to proprioceptive neck activation in humans. Thirteen healthy subjects (6 female, mean age 25) were exposed to passive body rotations while maintaining a head-fixed, gravitationally upright, position. Participants were seated in a mechanical sled, their heads placed in a chin rest embedded in a wooden beam while wearing an eye tracker attached to the beam using strong rubber bands to ensure head stability.

Uveal melanoma (UM) metastasises in ~50% of patients, most frequently to the liver. Surveillance imaging can provide early detection of hepatic metastases; however, guidance regarding UM patient risk stratification for surveillance is unclear. This study compared sensitivity and specificity of four current prognostic systems, when used for risk stratification for surveillance, on patients treated at the Liverpool Ocular Oncology Centre (LOOC) between 2007-2016 ( = 1047).

Mitochondrial elongation in the macular RPE of aging monkeys, evidence of metabolic stress.

Graefes Arch Clin Exp Ophthalmol

June 2016

Department of Ophthalmology, Columbia University, New York City, NY, USA.

Purpose: This study was conducted to determine whether mitochondria of the macular retinal pigment epithelium (RPE) change with age in rhesus monkeys (Macaca mulatta). Mitochondria are the main instigators of oxidative stress, which has often been considered to play a role in the pathogenesis of age-related macular degeneration (AMD). Any pathological changes in the mitochondria of aging macular RPE, the main target of AMD, would be a clue to the pathogenesis of this common retinal degeneration afflicting both monkey and man.
