项目摘要

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.

描述（由申请人提供）：会聚障碍和屈光性弱视是一般验光临床实践中最常见且可治疗的视力问题。 Oce 和家庭视力治疗（分别为 OBVT 和 HBVT）是此类疾病的标准治疗方法。计算机化视频治疗的最新进展模拟了在验光师办公室进行的视觉治疗练习，为 OBVT 提供了一种成本更低、更方便的替代方案。当前商业 HBVT 系统的缺点是推荐的眼保健操高度重复、单调且无趣，这导致患者高度不依从。这带来了一个问题，因为一致的表现和正确的技术是实现治疗效果的关键。另一种方法具有提高 HBVT 成功率的强大潜力，即将视觉治疗融入有趣的互动电脑游戏中，让患者更感兴趣。为了满足这一需求，Barron Associates 建议开发一种名为 iCare 的新型计算机化虚拟现实 HBVT 系统，该系统将通过解决成功家庭治疗的三个障碍来克服现有系统的局限性：（1）患者依从性； (2) 程序的准确性； (3) 验光师监督培训的能力。所提出的方法利用了为视频游戏市场开发的先进人机界面设备 (HID)（例如 Wii 遥控器）。由于视频游戏的流行，HID 技术在过去的价格昂贵得令人望而却步，现在可以以低成本（例如 < 40 美元）广泛使用。这些现成的 HID 允许在计算机显示器（用于“近点”视觉治疗）或等离子显示器（用于“远距离”视觉治疗）上创建虚拟三维 (3-D) 环境。基于“3D 眼镜”（即红蓝浮雕）的传统 3D 图形技术相对于观看设备的框架是静态的；也就是说，无论观看者相对于设备的位置如何，图像都是相同的。所提出的 iCare 技术通过低成本跟踪患者头部位置和方向来利用运动视差，创建动态视觉 3D 环境，该技术使观看者能够感知物体，就好像它们正在移动一样。用户甚至可以在几乎无限的 3D 空间中创建虚拟对象并进行操作。根据此 SBIR 快速通道拨款申请，提案团队将使用上述技术开发和测试 HBVT 原型计算机游戏环境，以提高治疗效果。 I期治疗的目标是治疗8-12岁儿童的屈光性弱视；第二阶段将重点治疗青少年和成人的屈光性弱视以及这两个人群的会聚不足。这些疾病显然适合视觉治疗，并且在临床实践中很常见。对于这两种视力问题，将在儿童中进行最流行的计算机化 HBVT 程序与 iCare 系统游戏的有效性比较临床研究，以评估 iCare 系统的有效性。
