Who Can Participate
Eligibility Criteria
You may qualify if you...
- Adults aged 18 to 99 years
- Normal eye exam within the last 2 years for control participants
- Defined structural defect for inner retina defect participants including ischemic optic neuropathy, branch retinal artery occlusion, hemianopia or visual field defect respecting vertical meridian, inherited mitochondrial optic neuropathies such as Leber's and Dominant Optic Neuropathy, other retinopathies or optic neuropathies
- Diagnosis of acute zonal occult outer retinopathy or other focal or diffuse outer photoreceptor loss of function for outer retina defect participants
- Mild cataracts allowed
You will not qualify if you...
- Cataract or media opacity that degrades retinal imaging (excluding mild cataracts)
- Any retina or optic nerve abnormalities affecting retinal metabolism outside of normal for control participants
- Cataract or media opacity that degrades retinal imaging for inner and outer retina defect participants
