Bielschowsky head-tilt test--I. Ocular counterrolling and Bielschowsky head-tilt test in 23 cases of superior oblique palsy.
We have measured the amplitude of ocular counterrolling (OCR) and the change in vertical deviation in the Bielschowsky head-tilt test (BHT) in 23 cases of unilateral superior oblique palsy. OCR was measured with a photographical method, using limbal, conjunctival vessels as landmarks. Average OCR of the healthy eye was 5.4 +/- 2.4 (SD) deg either side, at 45 deg of body-tilt. BHT and OCR (of th...
متن کاملHiroshi Ohtsuki Memorandum on Bielschowsky Head Tilt Test in Superior Oblique Palsy 2 . Relationship between Bielschowsky Head Tilt Phenomenon and Static Ocular
目的:頭部傾斜で誘発される静的眼球反対回旋(static ocular counterrolling, s-OCRと略)の振幅と Bielschowsky頭部傾斜試験の関係を調べる。 対象と方法:正常被験者11名、早期発症、および代償不全型上斜筋麻痺33名を対象に、頭部搭載型 の眼球運動計測システムを用いて、撮影した角膜反射像と虹彩紋理を結ぶ直線の形成する角度から 頭部傾斜で誘発される静的眼球反対回旋を計測した。 結果:患眼の患側頭部傾斜時のs-OCRの振幅の平均値(標準偏差値)は、健側頭部傾斜のそれに比 して有意に低値を示した[患側傾斜4.4°(2.1)vs. 健側傾斜 7.3°(2.7),p<0.0001]。また、それは 正常被験者のそれと比較しても低値を示した[7.3°(1.7),p<0.0001]。患側頭部傾斜時の患眼上斜 視とs-OCRの間には有意な関連はなかったが(r=0...
متن کاملDoes Decreased Static Ocular Counter Rolling Account for Bielschowsky Head Tilt Test in Unilateral Superior Oblique Palsy?
Purpose To understand the relationship of static ocular counter rolling (s-OCR) and clinical manifestations in acquired unilateral superior oblique palsy subjects during the Bielschowsky head tilt test. Methods Nineteen subjects that were diagnosed with acquired unilateral superior oblique palsy were included. Fundus photographs were obtained at different head tilt angles to evaluate static o...
متن کاملAbsence of relationship between oblique muscle size and bielschowsky head tilt phenomenon in clinically diagnosed superior oblique palsy.
PURPOSE To study whether the variation in maximum oblique muscle size accounts for individual variation in the Bielschowsky head tilt phenomenon (BHTP) in clinically diagnosed superior oblique (SO) palsy. METHODS Seventeen subjects with clinically diagnosed early-onset or idiopathic SO palsy and 14 normal subjects were enrolled in the study. Magnetic resonance imaging (MRI) in coronal and sag...
متن کاملParadoxical head tilt in unilateral traumatic superior oblique palsy
PURPOSE We report a patient with abnormal head posture following ocular blunt trauma. METHODS This is report of a case that despite findings compatible with diagnosis of left superior oblique (SO) palsy, the patient acquired an ipsilateral (left) head tilt. The interesting observation in our patient was reduction of left hypertropia and consequent less diplopia with ipsilateral head tilt. R...
