Group/Cohort Intervention/treatment
fundus imaging
retinal photograph obtained at visit
Device: Handheld fundus photography
diagnostic imaging with two types of retina camera
Other Name: imaging only

Primary Outcome Measures :
  1. Percentage of photographs that score a "3" or higher on the grading scale [ Time Frame: 2-3 years ]

    Photos will be evaluated by ophthalmologists and scored as follows:

    1. Unacceptable: cannot see fundus detail
    2. Unacceptable: fundus detail visualized, but inadequate for meaningful analysis
    3. Acceptable: fundus detail visualized enough to make general comments, with modest improvement image would be of sufficient quality for widespread use
    4. Good: fundus detail visualized, meaningful analysis possible, standard photograph superior
    5. Excellent: fundus detail visualized as well as standard photograph
    6. Superior: fundus detail of higher quality than standard photograph

Study Population
Ophthalmology clinic

Inclusion criteria:

  • Age > 18
  • The ability to give informed consent and be willing to spend up to two hours in the eye clinic during the duration of the study.
  • The subjects may have a normal retina and optic nerve, or subjects may have abnormalities of the posterior pole of the retina or the optic nerve.

Exclusion criteria:

  • Medical or ophthalmic instability that would create a contraindication for minimally invasive ophthalmic diagnostic testing will exclude participation as a subject.
  • Ophthalmic pathology felt by the principal investigator that would make retinal imaging with standard photographs difficult or not possible.
