Glaucoma is one of the leading causes of blindness. When a patient contracts glaucoma, the retinal nerve fiber layer (RNFL) thins and loses functionality. Unfortunately, because ganglion cell death is irreversible, blindness often results in the later stages of the disease if left untreated. Therefore, development of methods for early detection is crucial.
The purpose of the invention is to characterize functionality of nerves by measurement of mechanical changes associated with neural activation. The method has been demonstrated and is being developed as a tool that may be applied to diagnose neural pathologies at an early stage. The invention may aid in the early diagnosis of glaucoma, and possibly other neural diseases such as multiple sclerosis and Alzheimer?s. Moreover, the system may be useful for non-invasive physiologic monitoring in response to the application of pharmacologic agents. The method is applicable to study the functionality of all nervous tissue, including the brain, spinal cord, and peripheral nerves.
