Overview

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

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, other retinopathies or optic neuropathies.
        Exclusion:
        Cataract or media opacity that would degrade the imaging of the retina. Mild cataracts are
        okay.
        Subjects with Outer Retinal Defect:
        Inclusion:
        AZOOR (acute zonal occult outer retinopathy) or other focal or diffuse outer photoreceptor
        loss of function
        Exclusion:
        Cataract or media opacity that would degrade the imaging of the retina. Mild cataracts are
        okay.
        The 450 total is to allow for exclusion of some subjects or in the event that the enrolled
        subject blinks too much or cannot fixate on a visual target adequately to maintain the same
        eye position during the short imaging interval. We hope to have a total of 450 (50 controls
        and 400 patients)
