To conduct a precision study to assess the microperimetry function of the Spectral OCT/SLO. The study will assess variability across measurements taken by three different operator-device configuration across clinical sites, variability between subjects within a given operator-device configuration, and variability within a subject for a single operator-device configuration.

Study Population
Twenty-four subjects, 12 without retinal disease (Cohort 1) and 12 with retinal disease (Cohort 2) will be recruited. Any subjects that do not comply with or complete the study protocol will be replaced to ensure that a total of 24 subjects complete the protocol. Subjects will be screened and recruited based on the Inclusion/Exclusion criteria outlined within this protocol. Subjects fulfilling the stated criteria and who are willing to comply must sign an informed consent prior form to study participation.

Inclusion Criteria:

  • Subject must be 21 years of age or older.
  • Subjects recruited to Cohort 1 will have no known retinal disease except for refractive errors (-7.5 D to +7.5 diopters).Subjects who are recruited to Cohort 2 will have one or more of the following retinal pathologies: early and intermediate Age-Related Macular Degeneration, Geographic Atrophy, Diabetic Retinopathy (mild, moderate, severe), Macular Edema secondary to Diabetes, Retinal Vein Occlusion, Central Serous Retinopathy, Pattern Dystrophy, Epiretinal Membrane or Macular Hole.
  • Subjects who have signed an informed consent form.
  • Subjects who can comply with the protocol.

Exclusion Criteria:

  • Subjects younger than 21 years of age.
  • Subjects who cannot comply with the protocol.
  • Subjects who cannot complete the Simple Test procedures
  • Subjects who are not available to be testing 3 times during the day (Morning, Mid - Day, and Afternoon).
  • Subjects with visual acuity worse than 20/100 (Best Corrected).
  • Subjects with dense media opacities.
  • Ocular surgery anticipated on the day of the study visit.
