Summary/Abstract The broad goals of this Core are to provide facilities for vision scientists at Columbia University. Resources are provided for imaging, histology and electroretinographic recording. The module is administered so as to ensure equipment access, technical support and personnel training. The availability of shared state-of-the-art equipment and facilities operated by trained and highly qualified technicians with oversight by vision faculty substantially increases the quality and quantity of achievements earned by research programs. Productive functioning of these core facilities will i) facilitate collaborative efforts; ii) enable the tackling of gaps in our knowledge that require multiple areas of expertise; enhance the productivity of ongoing research making research funds more profitable; and enable the development of new research strategies. The clustering of clinically applicable instruments with in the Core enhances interactions between research and clinical faculty and encourages translational research. The availability of the resources of the Core is also an advantage when recruiting new faculty. The core provides training for students and postdoctoral associates in in vivo eye imaging using modalities of short-wavelength fundus autofluorescence, near-infrared fundus autofluorescence and optical coherence tomography (OCT). Training in tissue processing and sectioning for histological analysis is also made available as is training in electroretinographic (ERG) recording of visual function. The Core supports a clinical grade animal-dedicated confocal laser scanning ophthalmoscope (Heidelberg) equipped for short-wavelength fundus autofluorescence (AF), near-infrared fundus autofluorescence, angiography and spectral domain optical coherence tomography (SD-OCT). Two new high resolution Bioptigen SD-OCT (Envisu R2210 and R4310) enable non-contact in vivo SD-OCT imaging of the eye in animal models. This capability will advance investigations of cornea, tear film, lens, glaucoma and retinal structure in both the diseased and healthy eye. The instruments enable the study of animal models of disease in parallel with human subjects research. The core maintains 3 instruments for ERG testing. These machines are used to test the function of retinal pigment epithelium (bleach protocol, c-wave), photoreceptors (scotopic and photopic serial intensities), and retinal ganglion cells in rodents. Skilled personnel under the direction of Dr. Sparrow manage day to day activities including training in the use of the instruments. Reserving and tracking of usage time and scheduling of maintenance together with other day- to-day activities are managed by iLAB software.

摘要/摘要 这个核心的广泛目标是为哥伦比亚大学的视觉科学家提供设施。资源是 用于成像、组织学和视网膜电记录。对模块进行管理，以确保 设备准入、技术支持和人员培训。共享最先进设备的可用性 和设施由训练有素和高素质的技术人员运营，并由VISION教员监督 提高研究项目成果的质量和数量。的生产性运作 这些核心设施将：1)促进合作努力；2)使我们能够填补我们知识中的差距， 需要多个领域的专业知识；提高持续研究的生产力，使研究资金更多 盈利；并使开发新的研究战略成为可能。临床适用的聚类法 带In the Core的仪器加强了研究和临床教师之间的互动，并鼓励 翻译研究。核心资源的可用性在招聘新员工时也是一项优势 教职员工。 CORE为学生和博士后提供使用以下方式进行活体眼部成像的培训 短波长眼底自发荧光、近红外眼底自发荧光和光学相干 断层扫描(OCT)。还提供组织处理和切片方面的培训，以进行组织学分析 对视觉功能的视网膜电信号(ERG)记录的培训也是如此。 核心支持临床级动物专用激光扫描检眼镜(海德堡) 配备了短波长眼底自发荧光(AF)、近红外眼底自发荧光、 血管造影术和光谱域光学相干断层扫描(SD-OCT)。两种新的高分辨率生物膜 SD-OCT(Envisu R2210和R4310)能够在动物模型中对眼睛进行非接触式SD-OCT成像。 这一能力将促进对角膜、泪膜、晶状体、青光眼和视网膜结构的研究 患病和健康的眼睛。这些仪器使疾病的动物模型研究能够与人类平行进行。 主题研究。 核心有3台ERG测试仪器。这些仪器是用来测试视网膜功能的。 色素上皮(漂白方案，c波)，光感受器(暗视和明视连续强度)，以及 啮齿动物的视网膜神经节细胞。 在Sparrow博士指导下的熟练人员管理日常活动，包括使用 这些乐器。与其他日子一起预留和跟踪使用时间和维护计划- 日常活动由iLab软件管理。
