DESCRIPTION (provided by applicant): The main objective of this SBIR Phase I research is to develop and test a software prototype. The prototype will lead to a software product. It will be a clinical tool that helps clinicians to assess the condition of patients who are at risk of or who have diabetic neuropathy. The software will analyze optically sectioned images of subbasal nerve fiber layers in the cornea. Collaborators have seen a clear structural difference in the nerve fibers when diabetic neuropathy is present or progresses. These structural changes will help detect that a patient is at risk or developing the condition, before symptoms occur, or that the condition is stabilized or worsening. Typically the software will be utilized following standard clinical examination that includes neurological tests, to confirm suspicions or findings arising during the examination. Information that the software will provide includes statistical summaries of the quantified shapes of the nerve fibers. These data will be presented in a report that is efficient and easy to use in the clinic. Preliminary data produced by our collaborators indicate that the density, length and other measures change with the condition. The Phase I project will build a first prototype and show feasibility of developing a software product for the clinic. The Phase II project will build a refined prototype and carry out further testing, making it ready for integration into a product. The end product will have 3 general purposes: (1), for confirming or corroborating assessment from clinical examination, (2) screening at-risk patients, and (3), following patients who are developing diabetic neuropathy. The first purpose, (1), will, in many cases, replace the more invasive electromyography (EMG) procedure which is uncomfortable to patients, and in some cases serve as an adjunct or precursory test to EMG. Because it carries less risk and discomfort compared to EMG, it is expected that physicians will be more aggressive to order the tests to screen for or rule out diabetic neuropathy. The specific aims are: (1) Design and implement algorithms for counting and measuring nerve endings in the cornea. (2) Prototype software that provides statistical summaries of these measurements. (3) Test the software by showing a correlation (by regression analysis) between these measures and the clinical assessment of a group of cases that are recorded in an existing database. PUBLIC HEALTH RELEVANCE The project will lead to a software product that helps to diagnose and monitor patients who are at risk of or have diabetic neuropathy. The end product will have 3 general purposes: (1), for confirming a diagnosis, (2) Screening at-risk subjects, and (3), following subjects who are developing diabetic neuropathy. The 1st purpose will, in many cases, replace the more invasive EMG procedure which is uncomfortable to patients.

描述（由申请人提供）：SBIR第一阶段研究的主要目标是开发和测试软件原型。原型将导致一个软件产品。它将成为一种临床工具，帮助临床医生评估有糖尿病神经病变风险或患有糖尿病神经病变的患者的病情。该软件将分析角膜中基底下神经纤维层的光学切片图像。合作者已经看到，当糖尿病神经病变存在或进展时，神经纤维中存在明显的结构差异。这些结构变化将有助于在症状出现之前检测患者是否处于风险或发展状况，或者病情是否稳定或恶化。通常情况下，将在标准临床检查（包括神经学检查）后使用该软件，以确认检查期间出现的可疑或发现。该软件将提供的信息包括神经纤维的量化形状的统计摘要。这些数据将在一份有效且易于在临床中使用的报告中呈现。我们的合作者产生的初步数据表明，密度，长度和其他措施随条件而变化。第一阶段项目将建立第一个原型，并展示为诊所开发软件产品的可行性。第二阶段项目将建立一个完善的原型，并进行进一步的测试，使其准备集成到一个产品。最终产品将有3个一般用途：（1）用于确认或证实临床检查的评估，（2）筛选风险患者，以及（3）随访发生糖尿病神经病变的患者。第一个目的，（1），在许多情况下，将取代更具侵入性的肌电图（EMG）程序，这是不舒服的病人，并在某些情况下作为一个辅助或辅助测试肌电图。因为它带来的风险和不适相比，肌电图，预计医生将更积极地下令测试，以筛选或排除糖尿病神经病变。具体目标是：（1）设计并实现角膜神经末梢的计数和测量算法。(2)提供这些测量的统计摘要的原型软件。(3)通过显示这些测量与现有数据库中记录的一组病例的临床评估之间的相关性（通过回归分析）来测试软件。公共卫生相关性该项目将产生一种软件产品，有助于诊断和监测有糖尿病神经病变风险或患有糖尿病神经病变的患者。最终产品将具有3个一般目的：（1）用于确认诊断，（2）筛选风险受试者，以及（3）随访发生糖尿病神经病变的受试者。在许多情况下，第一个目的将取代对患者不舒服的更具侵入性的EMG程序。
