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 &#x3bc;A or more but not exceeding 300 &#x3bc;A from each placed electrode.

Ophthalmic treatment stimulation method for inhibiting death of retinal cells

An ophthalmic treatment apparatus includes an electrode which is set on a place to apply electrical stimulation to cells constituting a retina; and an electrical stimulation pulse generator which is connected to the electrode, for generating, from the electrode, a predetermined electrical stimulation pulse whose electric current is set at 20 &#x3bc;A or more but not exceeding 300 &#x3bc;A.
