A method of treating reperfusion injury in a tissue of a subject in need thereof. The method includes applying light, to the tissue, that inhibits electron transfer from cytochrome c to cytochrome c oxidase (CcO) to molecular oxygen to attenuate creation of reactive oxygen species. The light includes wavelengths in a first wavelength range of 730-770 nm and a second wavelength range of 930-970 nm.

Light therapy treatment

A method of treating an ischemic event in tissue of a subject in need thereof, includes applying light to a tissue susceptible to ischemic reperfusion injury, the light having a wavelength selected from two wavelength ranges selected from 730-770 nm, 850-890 nm, 880-920 nm, and 930-970 nm, thereby to reduce ischemic reperfusion injury in the tissue of the subject.

A light therapy method, comprising identifying a pathological condition in a patient, selecting at least one light wavelength based on the identified pathological condition, and applying one or a combination of the selected light wavelengths to the patient using a light source.

An exemplary method includes selecting at least one light source configured to generate light at a particular wavelength and applying the light to tissue following an ischemic event. Applying the light to the tissue inhibits cytochrome c oxidase activity. Another exemplary method includes selecting at least one light source configured to generate light at a particular wavelength and applying the light to tissue following an ischemic event and prior to either reoxygenation of the tissue or clinical intervention to reduce cell damage. An exemplary light therapy device includes at least one light source configured to generate light having a wavelength of at least one of approximately 730-770 nm, 850-890 nm, 880-920 nm, and 930-970 nm.
