Abstract
DESCRIPTION (provided by applicant): The long-term objective of this application is to develop an imaging device for the early detection, diagnosis and quantification of the degree of midperipheral retinal ischemia in Diabetic Retinopathy (DR). Earlier dia gnosis of DR could facilitate intervention at a stage that may prevent or lessen permanent damage from the ravages of the disease, in turn, improving patient quality of life and reducing lifetime treatment costs. DR is one of the more debilitating potenti al outcomes of diabetes posing a major threat to the quality of life of diabetics. Experts believe that DR is the leading cause of blindness in the industrialized world in people between the ages of 25 and 74 years old. The American Academy of Ophthalmolog y states that DR is the leading cause of blindness among working Americans and currently affects nearly seven million people in the U.S. Early detection can help treat DR and salvage about 90 percent of vision loss, but about one-third of the diabetic popu lation remains undiagnosed, translating into approximately 5.7 million people in the U.S. Delay in the primary diagnosis of diabetes allows diabetic complications to progress significantly before detection further increasing the risks associated with the d isease by making the treatment much more complicated. Diabetes management guidelines advocate initiation of therapeutic intervention early in the prognosis of the disease. Estimates of diabetics in the U.S. with DR range from 15% to as high as 40%. The go al of Neuro Kinetics diabetic screening methodology is to use a noninvasive, objective measure of diabetes-related damage to the peripheral retina that contributes to the development of central vision loss and the growth of abnormal blood vessels that can bleed and scar, leading to blindness. Unlike existing screening methods which employ photography of the back of the eye and reading centers, this device can provide an instantaneous answer to the patient and/or their doctor of the severity of the disease a nd indicate if immediate specialty eye care is warranted. By comparing the responses of an individual's pupil to varying brightness of lights directed either to the center of vision or to the peripheral vision, we can detect progressive retinal damage from DR while controlling for the effects of cataracts, medications, and autonomic dysfunction. Our preliminary data from a Phase I study has established testing conditions that appear to be capable of distinguishing individuals with moderate or severe DR from normal individuals with less than a 1:1000 false positive rate for normal people. We have the following specific aims for Phase II: (1) to develop a clinical version of the testing device that is self-contained and can operate more easily and rapidly in a lighted area; (2) to develop control, recording and automatic analysis software for assessment of data quality and interpretation; (3) to perform clinical testing on a total of 200 normal and diabetic subjects to establish the discrimination capabilities of the instrument as a screening tool and (4) to develop an application for pre-commercial FDA approval and testing. PUBLIC HEALTH RELEVANCE: According to the American Academy of Ophthalmology, Diabetic Retinopathy is the leading cause of blindness among working Americans and currently affects nearly seven million people in the U.S. There is widespread agreement that the current U.S. eye care delivery system cannot meet the screening needs of these patients by relying on traditional, clinical eye ex aminations. Neuro Kinetics is developing a rapid, noninvasive screening technology based on images of the pupil's response to unique patterns of light to detect retinal damage from diabetes at a stage that would warrant intervention and therapy to protect sight.
