Application of an electrical field in the vicinity of the trabecular meshwork to treat glaucoma
View Patent ↗The present invention is a method of treating glaucoma by applying an electric field in the vicinity of the juxtacanalicular region of the trabecular meshwork sufficient to cause migration or reorientation of glycosaminoglycans located in the extracellular matrix. A device for applying the electric field includes a controller coupled to a pressure sensor, and a pair of electrodes coupled to a voltage source. The electrodes apply the electric field, and the controller controls the application of the electric field based on IOP measurements from the pressure sensor.
1. A method of treating glaucoma in an eye having a juxtacanalicular region of a trabecular meshwork containing an extracellular matrix, the method comprising:
applying an electric field with a strength of between 500 and 5,000 Volts per centimeter in a vicinity of the juxtacanalicular region of the trabecular meshwork to cause migration or reorientation of glycosaminoglycans located in the extracellular matrix.
2. The method of claim 1 wherein the electric field is a pulsed electric field.
3. A method of treating glaucoma comprising:
providing a pair of electrodes coupled to a voltage source, the pair of electrodes having a spacing of less than one millimeter;
placing the pair of electrodes in the vicinity of the juxtacanalicular region of a trabecular meshwork; and
applying a voltage of between 50 and 500 volts across the pair of electrodes sufficient to cause migration or reorientation of glycosaminoglycans located in the extracellular matrix.
4. The method of claim 2 wherein the voltage applied is a series of voltage pulses.
