  • Ophthalmic treatment stimulation method for inhibiting death of retinal cells
    Patent number: 7706886
    Abstract: An ophthalmic treatment method for inhibiting death of retinal constitutive cells of an eye by stimulating the cells includes a first step of placing a positive electrode and a negative electrode in such positions outside the eye that the electrodes provide electrical stimulation to the cells, at least one of the electrodes being placed on one of a cornea and sclera of the eye; and a second step of generating an electrical stimulation pulse having an electric current set at 20 ?A or more but not exceeding 300 ?A from each placed electrode.
    Type: Grant
    Filed: January 18, 2006
    Date of Patent: April 27, 2010
    Assignee: Nidek Co., Ltd.
    Inventors: Takeshi Morimoto, Tomomitsu Miyoshi, Takashi Fujikado, Yasuo Tano, Yutaka Fukuda
