为了证明使用眼动数据来揭示婴儿眼震综合征(INS)的诊断特征的实用性,确定治疗,并估计和记录三名发育良好的眼窝期患者的治疗改善,相当广泛,横向凝视无效,\"头部转动,斜视,复杂的,多平面眼球震颤。
红外反射,磁搜索线圈,和高速数字视频系统被用来记录INS患者的眼球运动,Kestenbaum零点矫正手术前后(水平或垂直)。对数据进行了分析和估计,使用扩展的眼球震颤治疗函数(NAFX),该函数是MATLAB的OMtools工具箱的一部分。
在所有三个科目(S1-S3)中,峰值NAFX和最长凹域(LFD)均较Kestenbaum前值有所改善。S1:0.700-0.745(6.4%)和25-34°(36%),分别。S2:0.445-0.633(42.4%)和>40°至>50°(10%),分别。S3:0.250-0.300(20%)和13°到18°(见正文),分别。
S1:即使在治疗前NAFX和LFD光谱的高端,INS中心凹(因此,视觉功能)的改善可能足以证明眼球震颤手术的合理性,并提供对患者有益的临床改善。S2:垂直平面中的INS中央凹改善等于使用先前患者中的水平数据最初估计的那些。S3:基于优选的较低峰,两个明显的NAFX峰可以通过手术转化为非常宽的峰。
To demonstrate the utility of using eye-movement data to reveal the diagnostic characteristics of infantile nystagmus syndrome (INS), determine treatment, and both estimate and document therapeutic improvements in three patients with well-developed foveation periods, fairly broad, lateral gaze \"nulls,\" head turns, strabismus, and complex, multiplanar nystagmus.
Infrared reflection, magnetic search coil, and high-speed digital video systems were used to record the eye movements of INS patients, pre- and post-Kestenbaum null-point correction surgery (horizontal or vertical). Data were analyzed and estimations made, using the eXpanded Nystagmus Acuity Function (NAFX) that is part of the OMtools toolbox for MATLAB.
In all three subjects (S1-S3), both peak NAFX and longest foveation domain (LFD) improved from their pre-Kestenbaum values. S1: 0.700-0.745 (6.4%) and 25-34° (36%), respectively. S2: 0.445-0.633 (42.4%) and >40° to >50° (10%), respectively. S3: 0.250-0.300 (20%) and 13° to ≫18° (see text), respectively.
S1: Even at the high ends of the pre-therapy NAFX and LFD spectra, INS foveation (and therefore, visual-function) improvements may be adequate to justify nystagmus surgery and provide clinical improvements beneficial to the patient. S2: INS foveation improvements in the vertical plane are equal to those originally estimated using the horizontal data in prior patients. S3: Two apparent NAFX peaks can be converted into a very broad peak by surgery based on the preferred lower peak.
