1. A non-invasive method for focal non-invasive transcleral destruction of living human eye tissue, comprising the steps of:

  • (a) providing a hollow probe having a distal end and a proximal end;

    and, at said distal end a first aperture to receive a conductive electrode and means for filling said probe with a neutral solution;

    and, at said proximal end a second aperture of predetermined diameter;

    (b) connecting said conductive electrode to a constant current supply having a positive terminal and a negative terminal;

    (c) filling said probe with a neutral solution using said filling means;

    (d) adjusting said constant current supply to a current in the range of between about 1.5 milliamps to about 8.0 milliamps;

    (e) repeated placement of said proximal end of said probe onto a scleral surface of a human eye proximate to target eye tissue at a plurality of locations; and

    (f) each of said placement remains for a predetermined duration.
