NCT06451068

Brief Summary

Optical coherence tomography (OCT) is a 3D imaging technology that has seen wide adoption within ophthalmology. However, optical access to the retinal periphery remains a challenge for conventional OCT systems. The study team plans to innovate peripheral retinal OCT imaging technology by first developing the first robotic OCT system capable of autonomously assisting the operator during imaging of the human peripheral retina using 3D active tracking and compensation and then by developing of the first OCT system designed for treatment of the retinal periphery.

Study Arms (4)

Group 1 - Healthy adult volunteers

EXPERIMENTAL

Healthy adult volunteers recruited from the patient population, students or employees of Duke University or Duke Eye Center (n=7)

Device: Peripheral retina robotically aligned optical coherence tomography (OCT) systemOther: Likert Scales

Group 2 - Adult participants with "flashers and floaters"

EXPERIMENTAL

Adult participants recruited from the patient population of Duke Eye Center with complaints of "flashers and floaters" undergoing clinical examination (n=7)

Device: Peripheral retina robotically aligned optical coherence tomography (OCT) systemOther: Likert Scales

Group 3 - Adult participants with flashers and floaters with no diagnosed peripheral retinal breaks

EXPERIMENTAL

Adult participants recruited from the patient population of Duke Eye Center with complaints of "flashers and floaters" and a clinical examination showing no breaks in the peripheral retina (n=22)

Device: Peripheral retina robotically aligned optical coherence tomography (OCT) systemOther: Likert Scales

Group 4 - Adult participants with flashers and floaters with diagnosed peripheral retinal breaks

EXPERIMENTAL

Adult participants recruited from the patient population of Duke Eye Center with complaints of "flashers and floaters" and a clinical examination showing one or more breaks in the peripheral retinal (n=22)

Device: Peripheral retina robotically aligned optical coherence tomography (OCT) systemOther: Likert Scales

Interventions

To visualize the full 360° of the retinal periphery (from equator to the more anterior ora serrata), investigators developed and redesigned a conical mirror contact lens and our non-contact robotically aligning platform to deliver OCT to the peripheral retina. The peripheral retina robotically aligned OCT (PR-RAOCT) system is built around a 6-axis cooperative robot (UR5e, Universal Robots), using our previously developed RAOCT control software.

Also known as: PR-RAOCT
Group 1 - Healthy adult volunteersGroup 2 - Adult participants with "flashers and floaters"Group 3 - Adult participants with flashers and floaters with no diagnosed peripheral retinal breaksGroup 4 - Adult participants with flashers and floaters with diagnosed peripheral retinal breaks

Survey evaluating relative comfort with each type of peripheral exam (scleral depression vs. PR-RAOCT). Participants will rate 3 items on a 1 (non) to 5 (maximum) Likert scale: overall discomfort, physical pain, and photophobia for each exam.
