DESCRIPTION (provided by applicant): Convergence disorders and refractive amblyopia are among the most common and treatable vision problems seen in general optometric clinical practice. Oce- and home-based vision therapy (OBVT and HBVT, respectively) are standard treatments for such disorders. Recent advances in computerized video therapies that emulate vision therapy exercises performed in the optometrist's oce provide a lower-cost and more convenient alternative to OBVT. The downside of current commercial HBVT systems is that the recommended eye exercises are highly repetitive, monotonous, and uninteresting, which leads to high levels of patient noncompliance. This presents a problem since consistent performance and proper technique are key to achieving therapeutic benet. An alternative approach, which oers strong potential to increase the success of HBVT, is to incorporate vision therapy into fun and interactive computer games that patients will nd more engaging. To address this need, Barron Associates proposes to develop a novel computerized virtual reality HBVT system called iCare that will overcome the limitations of present systems by addressing three obstacles to successful home treatment: (1) patient compliance; (2) procedural accuracy; and (3) the ability of the optometrist to monitor training. The proposed approach takes advantage of advanced human-interface devices (HIDs) (e.g., Wii Remote Controllers) that have been developed for the video gaming market. Due to the popularity of video gaming, HID technology that would have been prohibitively expensive in the recent past is now widely available at low cost (e.g., < $40). These o-the-shelf HIDs permit the creation of virtual three-dimensional (3-D) environments on computer monitors (for \near-point" vision therapy) or plasma displays (for \distance" vision therapy). Traditional 3-D graphics technology based on \3-D glasses" (i.e., red-blue anaglyphs) is static with respect to the frame of the viewing device; that is, the image is the same regardless of the viewer's position relative to the monitor. The proposed iCare technology exploits motion parallax via low-cost tracking of the patient's head position and orientation, creating a dynamic visual 3-D environment. Visually, the technology allows the viewer to perceive objects as if they are coming o of, or receding into, the screen. This enables the creation of virtual xation objects in a nearly innite 3-D space. Users can even see \behind" and manipulate virtual objects. Under this SBIR Fast Track grant application, the proposing Team will develop and test prototype computer gaming environments for HBVT using the technology outlined above to improve treatment eectiveness. Phase I therapy will be aimed at treating refractive amblyopia in children 8-12 years of age; Phase II will focus on treating refractive amblyopia in teens and adults, as well as convergence insuciency in both populations. These disorders are clearly amenable to vision therapy and are common in clinical practice. For both vision problems, clinical studies of the comparative eectiveness of the most popular computerized HBVT programs vs. the iCare system's games will be conducted in children to assess the ecacy of the iCare system. PUBLIC HEALTH RELEVANCE: Convergence insuciency is one of the most common binocular vision disorders, and refractive amblyopia a vision disorder for which a very-high percentage of patients seek treatment; both disorders aect millions of U.S. children and adults. Such vision anomalies can cause a variety of chronic symptoms which, left untreated, often degrade academic and work performance; they may even result in learning disabilities in some cases. Computerized home-based vision therapy (HBVT) provides a relatively low-cost and convenient treatment option; however, the available commercial HBVT programs are highly repetitive and dull, leading to poor compliance. The goal of this research is to make HBVT a more eective alternative to oce-based vision therapy by incorporating the eye exercises into fun, interesting, and interactive computer video games that patients will nd more engaging, which should lead to better compliance and improved therapeutic outcomes.

描述（由申请人提供）：收敛障碍和屈光弱视是一般验光临床实践中最常见和可治疗的视力问题之一。 OCE和家庭视力疗法（分别为OBST和HBVT）是此类疾病的标准疗法。在验光师的OCE中进行视觉疗法练习的计算机视频疗法的最新进展为OBLT提供了低成本且更方便的替代方案。当前商业HBVT系统的缺点是，建议的眼睛锻炼是高度重复，单调且无趣的，这导致了高水平的患者不合规。这提出了一个问题，因为一致的性能和适当的技术是实现治疗良好的关键。 一种增加HBVT成功潜力的替代方法是将视觉疗法融入有趣和互动的计算机游戏中，患者将更具吸引力。为了满足这一需求，Barron Associates建议开发一种新型的计算机虚拟现实HBVT系统，称为ICARE，该系统将通过解决成功家庭治疗的三个障碍来克服当前系统的局限性：（1）患者合规性； （2）程序准确性； （3）验光师监测训练的能力。 拟议的方法利用了为视频游戏市场开发的高级人体接口设备（HIDS）（例如Wii遥控器）。由于视频游戏的普及，最近过去的HID技术将以低成本（例如<$ 40）广泛使用。这些O-The-the-thef HID允许在计算机监测器（用于\接近点“视觉疗法）或等离子体显示（用于\距离”视觉疗法上的虚拟三维（3-D）环境。传统的3-D图形技术基于\ 3-d眼镜”（即，红蓝色的血统）对于观看设备的框架是静态的；也就是说，与监视器相对于监视器相对于监视器的位置如何，图像是相同的。所提出的ICARE ICARE技术可以通过低成本进行动态视图，以使患者的头位和前方的视觉范围允许动态视觉范围，从而允许动态访问型，并访问动态的环境。好像它们是o的o或逐渐变成屏幕。 在此SBIR快速拨款应用程序下，建议团队将使用上述技术来开发和测试HBVT的原型计算机游戏环境，以提高治疗效率。第一阶段的治疗将旨在治疗8-12岁儿童的屈光弱视；第二阶段将着重于治疗青少年和成年人的屈光弱视，以及两个人群的融合差距。这些疾病显然可以接受视力疗法，并且在临床实践中很常见。对于这两个视力问题，最受欢迎的计算机HBVT程序与ICARE系统的游戏的比较纤维性临床研究将在儿童中进行，以评估ICARE系统的环境。 公共卫生相关性：融合助理是最常见的双眼视力障碍之一，而屈光弱视是一种视力障碍，其中很大比例的患者寻求治疗；这两种疾病都赋予了数百万美国儿童和成人。这种视力异常会导致多种慢性症状，这些慢性症状不受治疗，经常降低学术和工作表现；在某些情况下，它们甚至可能导致学习障碍。基于计算机化的家庭视力疗法（HBVT）提供了相对较低的较低成本和方便的治疗选择；但是，可用的商业HBVT计划具有高度重复和乏味，导致依从性差。这项研究的目的是通过将眼睛的锻炼纳入有趣，有趣和交互式的计算机视频游戏中，使HBVT成为基于OCE的视力疗法的更有效替代品，患者将更具吸引力，这应该可以提高更好的合规性和改善的治疗结果。
