NCT02826655

Brief Summary

This is a feasibility study to assess the use of wide field adaptive optics optical coherence tomography (WF-AO-OCT) to determine whether there are structural differences in the peripheral retina in participants diagnosed with diabetic retinopathy compared to a healthy control group. This study being conducted under an abbreviated IDE. The investigators will analyze data using descriptive statistics. Risks related to light exposure will be managed by ensuring that the exposure to the WF-AO-OCT light source is well below maximum permissible limits for safe exposure.

Outcome Measures

Primary Outcomes (2)

  • Image Quality

    Assessment of quality of images obtained by WF-AO-OCT unit.

    30 minutes

  • Peripheral Retina Structure Differences between Healthy Controls and participants with diabetic retinopathy.

    Differences between the control and case populations will be described using descriptive statistics. This data can then be used to power future, more dedicated studies.

    30 minutes

Study Arms (2)

Healthy Controls

ACTIVE COMPARATOR

Study participants will undergo imaging of both eyes with the WF-AO-OCT unit, per standard operating protocol. Imaging is noncontact. Study participants will undergo only a single imaging session on a single day.

Device: WF-AO-OCT

Subjects with diabetic retinopathy

EXPERIMENTAL

Study participants will undergo imaging of both eyes with the WF-AO-OCT unit, per standard operating protocol. Imaging is noncontact. Study participants will undergo only a single imaging session on a single day.

Device: WF-AO-OCT

Interventions

WF-AO-OCTDEVICE

WF-AO-OCT allows noninvasive, high-resolution imaging of the microvasculature of the retina and choroid, without intravenous dye administration. This unit is being conducted under an abbreviated IDE.

Healthy ControlsSubjects with diabetic retinopathy
