About

Handheld optical coherence tomography (OCT) has become an important imaging modality to evaluate the pediatric retina. The objective of this pilot study is to compare a new contact OCT system (Theia Imaging) with an investigational noncontact OCT system (Duke Biomedical Engineering) to assess their ability to image the pediatric retina.

The investigators hypothesize that the contact OCT system is superior in imaging larger areas of the retina (larger field-of-view), while it has similar resolution to image the retina substructures (non-inferior image quality).

Full description

Handheld optical coherence tomography (OCT) has become an important imaging modality to evaluate the pediatric retina. The objective of this pilot study is to compare a new contact OCT system (Theia Imaging) with an investigational noncontact OCT system (Duke Biomedical Engineering) to assess their ability to image the pediatric retina.

The investigators plan to enroll 10 healthy adult volunteers and 20 pediatric patients in clinic or undergoing examination under anesthesia. This is an observational study. There are no known risks associated with handheld OCT imaging and no adverse events identified imaging with our prior investigational imaging with the same system. There is a risk of corneal abrasion with the contact imaging system (Theia imaging), however, this system is used in the setting of other contact imaging systems (such as RetCam fundus photography).

Imaging data will be downloaded to a secure server for protocol image processing, segmentation, and analysis per protocol in the Duke Advanced Research in SD/SSOCT Imaging (DARSI) Laboratory.

Enrollment: 30 estimated patients
