Eye researchers develop new 3-D monitor vision test for children
Rockville, Md. -- A new random-dot stereotest using a 3D display and infrared oculography has been found to objectively assess stereopsis in children older than three years according to an article published in the November 2006 issue of Investigative Ophthalmology & Visual Science (IOVS).
The study involved 56 children, 38 with various visual impairments and 18 with normal vision. Study participants were seated on their mother's lap or alone with their heads stabilized by a chin and front rest. Unlike a number of other tests, this new 3D monitor stereotest does not require disassociating glasses that children often find cumbersome. The random dot stimulus was presented on an autostereoscopic display which allows viewing of full-color 3D images. The stimulus recognition was objectively assessed using infrared photo-oculography. The overall accuracy of the test was found to be 95 percent.
If applicable to preverbal children, the new test may permit study of the development of stereovision under natural conditions since no glasses are necessary to see the stimuli. The new test may be useful for the objective measurement of the sensory outcome following the treatment of ophthalmic disorders in the pediatric age group. It is also a potential substitute for the Lang I and II Test and the Radom-dot E Test, which require verbal capabilities from the subject tested.

The new test setting was developed by Daniel Mojon, MD, FEBO, of Kantonsspital St.Gallen in Switzerland, and the stimulus presentation algorithm by Xiaoyi Jiang, PhD, of the University of Muenster in Germany.

眼科学家为孩子们发明了一种3-D视力检测试验
Rockville, Md. -- A new random-dot stereotest using a 3D display and infrared oculography has

马里兰州罗克韦尔 ---根据一篇发表在2006年11 月出版的眼科学与视觉科学研究期刊（IOVS）上的文章，一种新的应用3D显示器和红外眼图的随机点阵立体视觉检测试验已经建立，用于客观评估那些大于三岁的儿童的立体试觉。
The study involved 56 children, 38 with various visual impairments and 18 with normal vision. Study participants were seated on their mother's lap or alone with their heads stabilized by a chin and front rest. Unlike a number of other tests, this new 3D monitor stereotest does not require disassociating glasses that children often find cumbersome. The random dot stimulus was presented on an autostereoscopic display which allows viewing of full-color 3D images. The stimulus recognition was objectively assessed using infrared photo-oculography. The overall accuracy of the test was found to be 95 percent.
这项研究有56个儿童参加，其中38有各种各样的视觉损害，18个视觉正常。这些研究参与者坐在他们妈妈膝上或单独用下巴和前额支托将头部固定。不像其他的检测，这项新的3D立体视觉监测试验不需要摘掉眼镜，避免使儿童们厌烦。随机刺激光点由可以表现各色3D图像的自动立体显示器产生。刺激识别客观地利用红外眼图评估。这项试验的整体准确度达到了95%.
If applicable to preverbal children, the new test may permit study of the development of stereovision under natural conditions since no glasses are necessary to see the stimuli.
