Abstract

Static roll-tilt of normal healthy subjects causes the ocular tilt reaction (OTR) one component of which is disconjugate vertical eye position (skew deviation). In this study the magnitude of skew was measured subjectively by the use of a computerized Hess test at three static roll-tilt angles (head erect, left ear down and right ear down) and two viewing distances (20 cm and 60 cm). The results showed that during static roll-tilt there was a small skew deviation, the magnitude of which was increased at close viewing distances.

摘要

正常健康受试者的静态侧滚倾斜会引发眼倾斜反应（OTR），其中一个组成部分是眼球垂直位置分离（斜视角）。在本研究中，通过计算机化的Hess试验，在三个静态侧滚倾斜角度（头部直立、左耳向下和右耳向下）以及两个观察距离（20厘米和60厘米）下主观测量斜视角的大小。结果表明，在静态侧滚倾斜过程中存在较小的斜视角偏差，在近距离观察时其大小会增加。
