ABSTRACT:
A non-invasive method for focal transcleral destruction of living human eye tissue. The method includes providing a conical-shaped probe, filled with a neutral saline solution and having inserted therein an electrode connected to the positive terminal of a constant current supply. The narrow aperture ends of the probe is lowered onto the conjunctiva overlying the target tissue, in about 20-30 locations with a current in the range from about 3.0-4.0 milliamps for about 30 seconds to 5 minutes at each location.
