To improve accuracy in diagnosis of retinal disease, ORNL researchers invented a method for assigning a confidence metric to computer-aided optic disc analysis. The physical condition of the optic disk determines the presence of various ophthalmic pathologies, including glaucoma and diabetic retinopathy. Unfortunately, localization of the optic disk and detection of its boundaries on the retinal i…

Retinal Instrument for Removing Scar Tissue from the Eye The retina of the eye is only 160 to 240 microns (millionths of a meter) thick and is generally transparent. Retinal scar tissue, a common problem for the elderly, is difficult to remove successfully. Surgeons currently peel it with an instrument that can result in a vision-threatening injury when misaligned or applied with too much pressur…

ORNL researchers invented a tomographic microscope that can obtain noninvasive, quantitative information about the 3-D position of structures within a sample. Accurate, full-field measurements of living organisms are useful for diagnostics, treatment, and prevention of disease. This invention can provide these measurements quickly. The microscope can also be integrated with epi-fluourescence for e…

PFTT-200401482, PFTT-200401483 Carbon Nanofiber Arrays Introduced as Artificial Local Environments into Cells To deliver materials and affect the intracellular function of a cell, ORNL researchers created an artificial local environment from carbon nanofibers. The invention allows materials to be introduced to select areas of a cell without interacting with other cellular components or regions. T…

Microrod Array Treats Erosion, Delivers Drugs to Cornea A device and a method for treating abrasion and recurrent erosion of the cornea of the eye were invented at ORNL. The cornea, responsible for two-thirds of the eye s optical power, can suffer recurrent erosion when a defect in its outermost layer, the epithelium, prevents epithelial cells from attaching to the adjacent Bowman s layer and str…

Biomedical optics is an emerging field with enormous potential to diagnose and treat diseases safely and economically. To determine the optical properties of tissue, ORNL researchers invented a new method, apparatus, and software. This invention meets the industry s need for a standardized optical property measurement system that provides accurate sample characterization and does not require costl…

Novel Instruments Usher in a New Paradigm for Eye Surgery (Cornea NanoPunch and Retina Velcro) ORNL scientists working in conjunction with the Hamilton Eye Institute at the University of Tennessee Memphis invented new methods and devices to reduce risk in surgical procedures for removing scar tissue and treating damage to the eye from corneal erosion. Retina Velcro and the Cornea NanoPunch repres…

The Triply Redundant Integrated Navigation and Asset Visibility System (TRI NAV) developed by researchers at ORNL expands the ability of GPS navigation systems to reliably function under a variety of adverse conditions, as well as detect multipath, jamming, or spoofing-induced errors. TRI NAV synergistically combines the use of GPS with a ground-based radio-frequency (RF) scheme known as TPS (the …

Internal/External Split Field Generator ORNL researchers developed inventions to improve the efficiency of electric generators. This is achieved by decoupling the magnetic polarity of the driving mechanism while increasing the operational frequency of the machine. These technologies offer unique, low cost methods to produce a generator with a higher power density. In both inventions, generators …

Novel Instruments Usher in a New Paradigm for Eye Surgery Current treatment for corneal erosions creates deep perforations in the corneal tissue, resulting in the formation of visible scars. The tissues in the area around the focus of treatment are also vulnerable to the scarring, with significant negative consequences for refractive and optical vision. Scientists at ORNL in conjunction with th…
