DESCRIPTION (provided by applicant): According to the National Institutes of Health, there are more than 80 million people in the US who suffer from a potentially sight-threatening disease. Doctors see seven to eight million new cases of eye disease annually. More than two million Americans age 50 and older have advanced AMD, the stage that can lead to severe vision impairment and 10 million have early or intermediate AMD. Glaucoma affects more than 2.3 million Americans age 40 and older. Another two million individuals with glaucoma are undiagnosed. Diabetes cases in the US and throughout the world have been on the rise. Poor eating habits and lack of exercise, factors which contribute to type 2 diabetes, have led to an increasingly overweight population. According to the International Diabetes Federation, there are 285 million cases of diabetes in the world as of 2010. For the type 2 diabetics, 50% will develop diabetic retinopathy within 15 years of disease diagnosis. Regular eye disease screening is necessary to prevent the progression of eye diseases to advanced, sight-threatening stages. The objective of this project is to develop and test a low-cost, hand-held, non-mydriatic retinal camera for widespread applications, including teleretinal screening for eye diseases such as diabetic retinopathy, glaucoma, and age-related ocular diseases. The proposed camera fills an important unmet need: low-cost (under $1,500 cost of goods); small footprint (principally a hand-held device); and easy to use (ergonomically designed for operation by a minimally trained medical technician or nurse). Introducing this technology to a clinic environment will allow underserved individuals to receive regular eye screenings without traveling to an eye care professional. To meet this goal, our proposal has two aims. First, we will produce a prototype of the low-cost, hand-held, non-mydriatic camera, which will be based on an early prototype of a mydriatic camera that was developed, and for which early testing has shown significant functionality. The design is based on low-cost, off-the-shelf components that can be assembled easily for a high- volume market. Second, we will test this camera in a screening or clinic environment. Making the camera ergonomically suitable for use by a minimally trained individual will be the goal of this aim. Quantitative analysis will be performed as to field of view, resolution, and safety.

描述（由申请人提供）：根据美国国立卫生研究院的说法，美国有超过8000万人患有潜在的视力危及疾病。医生每年看到7至800万例新的眼病病例。超过200万美国人50岁及以上的AMD升级了AMD，该阶段可能导致严重的视力障碍，而1000万的AMD早期或中间AMD。青光眼影响了40岁及40岁以上的230万美国人。另外200万个青光眼患者未被诊断。美国和世界各地的糖尿病病例一直在上升。不良的饮食习惯和缺乏运动，导致2型糖尿病的因素导致了越来越多的超重人群。根据国际糖尿病联合会的数据，截至2010年，世界上有2.85亿例糖尿病。对于2型糖尿病患者，50％将在诊断后的15年内患上糖尿病性视网膜病。需要定期进行眼病筛查，以防止眼部疾病的进展到高级，威胁视力范围的阶段。该项目的目的是开发和测试用于广泛应用的低成本，手持式的非毛线视网膜摄像头，包括对糖尿病性视网膜病变，青光眼和年龄相关的眼部疾病等眼部疾病的端脉筛查。提议的相机满足了重要的未满足需求：低成本（$ 1,500的商品成本）；小足迹（主要是手持设备）；易于使用（符合人体工程学设计，可由训练有素的医疗技术员或护士进行操作）。将该技术引入诊所环境将使服务不足的人可以定期进行眼部筛查，而无需前往眼部护理专业人员。为了实现这一目标，我们的建议有两个目标。首先，我们会的 生产低成本，手持式，非肌动摄像机的原型，该原型将基于开发的Mydriatic摄像头的早期原型，并为此表现出显着的功能。该设计基于低成本的现成组件，可以轻松地用于高批量市场。其次，我们将在筛查或诊所环境中测试该相机。将相机在人体工程学上适合于最低限度训练的人使用，这将是这个目标的目标。将进行定量分析，以了解视野，解决方案和安全性。
