Brief Summary
The overall objective of the proposed research is to test the hypothesis that Near-infrared Light-emitting Diode (NIR-LED) therapy will stimulate mitochondrial function, attenuate oxidative stress, and improve cell survival and vision in subjects with Leber's Hereditary Optic Neuropathy (LHON).

Outcome Measures
Primary Outcomes (1)
N95 Peak Via pERG and fERG -PhNR
The primary comparison will be a paired comparison of pre- and post-treatment retinal ganglion cell N95 pattern electroretinogram (pERG) peaks and fERG - Photopic Negative Response (PhNR). Pairing will be done between a subject's treatment and control eye.
12 months
Study Arms (2)
Symptomatic LHON patients.
EXPERIMENTALStudy Arm 1) symptomatic LHON patients. Male and female LHON patients with treatable bilateral optic atrophy. Treat the worse of the 2 eyes if there is a measurable difference in subjective visual functions (visual acuity, peripheral vision).
Asymptomatic LHON mutation carriers
NO INTERVENTIONStudy Arm 2) asymptomatic LHON mutation carriers. Can be male or female; have some dysfunction, with changes occurring over months. Patients in study arm 2 will not be exposed to NIR-LED, but only undergo diagnostic studies.
Interventions
Subjects will be exposed to light emitted from a Med Light 630 PRO (Medical Devices Inc.) at a wavelength of 630 nm (+/-15nm) with an exposure of 4 J/cm2. This is accomplished by applying the 50 mW/cm2 LED-generated light to the closed study eye for 80 seconds. Treatments involve application of the LED-generated light for 80 seconds, twice daily.
Eligibility Criteria
You may qualify if:
- Sex - male and female. Men are affected with visual loss more frequently than women, with a male predominance of \~85%. A minimum of 25% of men and 5% of women at risk for LHON experience visual loss.
- Age - 18 years or older. The onset of visual loss typically occurs between the ages of 15 and 35 years, but otherwise classic LHON has been reported in many individuals both younger and older, with a range of age at onset from 2 to 80 years.
- Diagnosis of LHON or a carrier of the gene mutation. Patient must be evaluated by molecular confirmation, with the 11778 and other mutations of Leber's Hereditary Optic Neuropathy stratified in later data analysis.
- Able \& willing to provide informed consent
You may not qualify if:
- Has an optic nerve disease other than LHON.
- Significant renal disease, defined as a history of chronic renal failure requiring dialysis or kidney transplant.
- Participation in an investigational trial within 30 days of NIR-LED treatment that involved treatment with any drug that has not received regulatory approval at the time of study entry. (Note: subjects cannot receive another investigational drug while participating in the study during the first 6 months.)
- Major surgery within 28 days prior to participation or major surgery planned during the next 6 months. Major surgery is defined as a surgical procedure that is more extensive than fine needle biopsy/aspiration, placement of a central venous access device, removal/biopsy of a skin lesion, or placement of a peripheral venous catheter.
