Abstract
Providing neuroprotective therapy for glaucoma includes generating a micropulsed laser light beam having parameters and characteristics, including pulse length, power, and duty cycle, selected to create a therapeutic effect with no visible laser lesions or tissue damage to the retina. The laser light beam is applied to retinal and/or foveal tissue of an eye having glaucoma or a risk of glaucoma to create a therapeutic effect to the retinal and/or foveal tissue exposed to the laser light beam without destroying or permanently damaging the retinal and/or foveal tissue and improve function or condition of an optic nerve and/or retinal ganglion cells of the eye.
Claims9
A system for providing glaucoma neuroprotective treatment, comprising:
- a laser console producing a micropulsed laser light beam having characteristics of providing a therapeutic effect to retinal and/or foveal tissue without destroying or permanently damaging the retinal or foveal tissue, the micropulsed laser light beam characteristics including a wavelength of 532 nm or greater and a duty cycle of less than 10%;
- an optical lens or mask that the laser light beam passes through to optically shape the laser light beam;
- a coaxial wide-field non-contact digital optical viewing camera projecting the laser light beam to an area of a retina and/or fovea of an eye;
- and
- an optical scanning mechanism for controllably directing the light beam onto the retina and/or fovea to provide a therapeutic effect to the retinal and/or foveal tissue and improve optical nerve and/or retinal ganglion cell function or condition, wherein the laser tight beam is controllably moved by the optical scanning mechanism to different treatment areas between micropulses of the laser light beam, and returned to a previously exposed area within less than one second of a prior exposure until a predetermined number of laser light beam exposures have been achieved in that treatment area.
