Inventor: WHITMORE ALAN
IPC: A61F9/00
Filed: 2007-01-22
Abstract: Currently, no efficient, non-invasive methods exist for delivering drugs and/or other therapeutic agents to the interior of the eye to treat or prevent disease or injury. The present invention relates to a novel method that is suitable for the delivery of any therapeutic agent (suitably modified) to the interior of the eye without the need for the penetration of a needle into the eyeball. In a preferred embodiment, it involves an injection into a peripheral vein (or oral administration, or administration by some other enteral or parenteral route) of a solution of inert drug which is trapped in the eye by a magnetic field and activated by radiation once it is in position, so that the active agent is released only where it is needed and can have its therapeutic effect without affecting other tissues or organs. The inert drug may be composed of a biologically compatible magnetic nanoparticle chemically bound to a specially inactivated (caged) form of the drug to be delivered and to a luminescent marker.

Title: Diagnostic and therapeutic system for eccentric viewing
Inventor: SCHLUETER DOROTHEE
IPC: A61B3/024
Filed: 2007-06-29
Abstract: A method is provided to map the sight perception of a patient and/or for therapeutically stimulating the patient. The method includes providing a target focal stimulation on a luminous background stimulation field so that the patient may focus upon the target and thereby keep the patient's retina in a fixed position. A temporary peripheral visual stimulation is then created in a region that is peripheral to the fixation target. The peripheral visual stimulation is darker than the background field. A computer records whether the patient was able to see the peripheral stimulation and stores the patient response data in a manner that maintains association with the position of the peripheral visual stimulation. The process is then repeated with additional stimuli and response recordations to create automatically, in computer media, a peripheral vision map. The vision map may be used to allocate a finite number of therapeutic stimuli to an identified visual field region of the patient having high therapeutic potential. The vision map may include a contrast dimension.
