New Non-invasive Modalities for Assessing Retinal Structure and Function:Preliminary Investigation
Randy Kardon
Summary
This study investigates a new technology to assess the structure and function inside the eye. Retinal imaging of subjects with inner and outer retinal defects to detect areas of abnormal structure and function compared to other visual function tests.
Eligibility
- Age range
- 18–99 years
- Sex
- All
- Healthy volunteers
- Yes
Controls: Inclusion: Normal eye exam in last 2 years Exclusion: Cataract or media opacity that would degrade the imaging of the retina. Mild cataracts are okay. Any abnormalities of the retina or optic nerve that could affect metabolism of the retina outside of normal. Subjects with Inner Retina Defect: Inclusion: Defined structural defect to include those with Ischemic optic neuropathy, branch retinal artery occlusion (BRAO), hemianopia or visual field defect that respects the vertical meridian, inherited mitochondrial optic neuropathies such as Leber's and Dominant Optic Neuropathy, o…
