DESCRIPTION (provided by applicant): A digital system for imaging the pediatric fundus, the RetCam, is requested. High-resolution images of the entire retina and magnified images of the optic nerve head (optic disc) and macula can be obtained. RetCam images surpass those that can be obtained with currently available fundus cameras. Each major user has a funded, clinical research study of infants and children with a history of preterm birth. Dr. Volpe and Dr. DuPlessis, investigate periventricular leukomalacia (PVL) which has associated abnormalities of the optic nerve head (optic disc). In these patients, analysis of the RetCam images of the optic nerve head (optic disc) provide an unprecedented oppoitunity to examine the relationship of disc fuatures and clinical history, structure of the periventricular white matter, visual and neurological function. Dr. Vanderveen is involved in the multicenter study, The Early Treatment of ROP (ETROP) in which subjects are enrolled and studied at preterm ages with postterm follow-up. Topography of acute ROP during its evolution and resolution will be documented with detail and accuracy that is currently impossible. For those subjects in the treatment arm of the ETROP study, the RetCain images will support the diagnosis of pre-threshold and threshold ROP, and document the response to laser treatment. Dr. Fulton and Dr. Hansen, enroll the former pretemis at postterm ages, but categorize subjects according to maximum acute phase ROP (determined at preterm ages). For this study of development of retinal function and refractive error in ROP subjects, RetCam images will document and refine the observations upon which their categorization of acute phase ROP is based. The RetCam images of the entire retinal surface area, combined with biometry of the globe, allow estimates retinal surface area in eyes with ROP, including those with multiple, small areas of retina ablated by laser treatment. These data will facilitate analysis of ERG results. The highly magnified RetCam images of the macula, including those obtained with fluorescein angiography, will, provide new information about this late-maturing portion of the central retina that may be paiticularly vulnerable to the ROP. The minor users will take advantage of the wide field images as well as the highly magnified views of the macula and optic nerve head (optic disc), including the fluorescein capability.

描述（由申请人提供）：用于儿科成像的数字系统 要求使用眼底 RetCam。整个视网膜的高分辨率图像 视神经乳头（视盘）和黄斑的放大图像可以 获得。 RetCam 图像超越了目前可获得的图像 可用眼底相机。每个主要用户都有一项受资助的临床研究 有早产史的婴儿和儿童。沃尔普博士和博士。 DuPlessis，调查脑室周围白质软化症 (PVL)，该病与 视神经乳头（视盘）异常。在这些患者中，分析 视神经乳头（视盘）的 RetCam 图像提供了 前所未有的机会来研究光盘特征和 临床病史、脑室周围白质结构、视觉和 神经功能。 Vanderveen 博士参与了多中心研究 ROP 的早期治疗 (ETROP)，受试者在以下机构入组并进行研究： 早产年龄和产后随访。急性 ROP 期间的地形图 演变和解决方案将被详细和准确地记录下来 目前不可能。对于 ETROP 治疗组中的受试者 研究中，RetCain 图像将支持阈值前和 阈值 ROP，并记录对激光治疗的反应。富尔顿博士和博士。 Hansen，在晚期年龄入组前早产儿，但对受试者进行分类 根据最大急性期 ROP（在早产儿时确定）。为了这 ROP 受试者视网膜功能和屈光不正发展的研究， RetCam 图像将记录并完善其观察结果 急性期 ROP 的分类依据。 整个视网膜表面区域的 RetCam 图像，结合生物测量 地球仪，允许估计 ROP 眼睛的视网膜表面积，包括 那些通过激光治疗切除了多个小区域的视网膜的人。这些 数据将有助于 ERG 结果的分析。高倍放大的 RetCam 黄斑图像，包括通过荧光素血管造影获得的图像， 将提供有关中央的这个晚熟部分的新信息 视网膜可能特别容易受到 ROP 的影响。未成年用户将 利用宽视野图像以及高度放大的视图 黄斑和视神经乳头（视盘），包括荧光素 能力。
