Poorly recognized age-related downward deviation of the inguinal ligament
OBJECTIVE To determine factors affecting actual inguinal ligament course in live human subjects. INTRODUCTION AND HYPOTHESIS Although the expected inguinal ligament course is supposedly a straight line extending from anterior superior iliac spine to pubic tubercle, the actual inguinal ligament course is frequently depicted a priori by a downward bowing dotted line. There are no studies in a l...
متن کاملVariability of Ocular Deviation in Strabismus.
IMPORTANCE In strabismus, the fixating eye conveys the direction of gaze while the fellow eye points at a peripheral location in space. The stability of the eyes may be reduced by the absence of a common target. OBJECTIVE To quantify the stability of eye position in strabismus and to measure variability in the ocular deviation. DESIGN, SETTING, AND PARTICIPANTS From 2010 to 2014, a prospect...
متن کاملThe Ocular Tilt Reaction and Skew Deviation
The ocular tilt reaction composes a triad of ipsiiateral head-tilt, ipsilaterai conjugate ocular torsion, and skew deviation with ipsilaterai hypotropia. It results from a disruption of central vestibular pathways conveying information from the semicircular canals and otoliths. Skew deviation is one component of the syndrome which may or may not be associated with the concomitant torsion and he...
متن کاملStatic ocular counterroll reflex in skew deviation.
OBJECTIVE The static ocular counterroll (OCR) reflex generates partially compensatory torsional eye movements during head roll. It is mediated by the utricle in the inner ear. Skew deviation is a vertical strabismus thought to be caused by imbalance in the utriculo-ocular pathway. We hypothesized that if skew deviation is indeed caused by damage to this reflex pathway, patients with skew deviat...
متن کاملPearls & Oy-sters: paroxysmal ocular tilt reaction.
Amadeo R. Rodriguez, MD Robert A. Egan, MD Jason J.S. Barton, MD, PhD, FRCPC In skew deviation, one eye is higher than the other, causing vertical diplopia. Skew deviation is a prenuclear disorder resulting from imbalance in otolith input to the oculomotor system, produced by unilateral lesions anywhere from the otoliths to the interstitial nucleus of Cajal in the rostral midbrain,1 and as such...
