Simultaneous recordings of ocular microtremor and microsaccades with a piezoelectric sensor and a video-oculography system.

Our eyes are in continuous motion. Even when we attempt to fix our gaze, we produce so called "fixational eye movements", which include microsaccades, drift, and ocular microtremor (OMT). Microsaccades, the largest and fastest type of fixational eye movement, shift the retinal image from several dozen to several hundred photoreceptors and have equivalent physical characteristics to saccades, only on a smaller scale (Martinez-Conde, Otero-Millan & Macknik, 2013).

Anosognosia for hemiplegia with preserved awareness of complete cortical blindness following intracranial hemorrhage.

A 51-year-old woman presented with anosognosia for hemiplegia (AHP), neglect, and a complete loss of vision, for which she was almost immediately aware. Neuroimaging studies revealed intracranial hemorrhages in the medial temporal lobes bilaterally, extending back to the occipital cortex, but sparing the calcarine cortex. A large right frontal-parietal hemorrhage which extended to the posterior body of the corpus callosum was also observed.

Resolution of mydriatic pupil after angioplasty and stenting of cervical internal carotid artery dissection: case report.

Objective: A patient with cervical internal carotid artery (ICA) dissection presented with visual loss and a mydriatic pupil that resolved after angioplasty and stenting.

Clinical Presentation: A 49-year-old woman presented with a unilateral dilated tonic pupil and transient monocular visual loss and subsequently developed speech disturbance. Angiography revealed a left cervical ICA dissection with significant luminal narrowing.
