DIAGNOSTIC AND THERAPEUTIC SYSTEM FOR ECCENTRIC VIEWING

摘要

A method is provided to map the sight perception of a patient and/or for therapeutically stimulating the patient. The method includes providing a tar get 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 patie nt response data in a manner that maintains association with the position of the peripheral visual stimulation. The process is then repeated with additi onal stimuli and response recordations to create automatically, in computer media, a peripheral vision map. The vision map may be used to allocate a fin ite number of therapeutic stimuli to an identified visual field region of th e patient having high therapeutic potential. The vision map may include a co ntrast dimension.
