Advancing Pediatric Retinal Imaging With Auto-aligned OCT

Handheld OCT imaging is an advancement in ophthalmic imaging technology allowing us to image the pediatric retina. lt has tremendous potential to be applied to assess the structure and blood flow of children with retinal vascular diseases or as a screening tool for pediatric retinal diseases. Despite progress in the development of hand-held OCT probes, there remains a critical gap in technology to achieve fast, proper alignment between the imaging device and the infant eye. Even with the most skilled operators, to acquire consistent OCT and OCTA data capture for longitudinal follow up in uncooperative patients at the bedside remains difficult. lmprovements in hand-held OCT probe technology for auto-alignment to the patient's eye, as well as on-line detection of image quality and auto-saving at the proper time, would address this critical gap in handheld OCT technology. Our biomedical engineering team, has developed prior iterations of the handheld OCT devices and successfully imaged the pediatric retina. The goal of the current study is to conduct a pilot study to test a new version of the handheld OCT device capable of auto-alignment to image the retina in adult volunteers, and adult and pediatric patients in clinic.

The investigators plan to enroll 20 healthy adult volunteers, 20 adult patients and 10 pediatric patients from the ophthalmology clinic. This is an observational study. There are no known risks associated with handheld OCT imaging and no adverse events identified imaging with prior iterations of handheld OCT devices. lmaging data will be downloaded to a secure server for protocol image processing, segmentation, and analysis per protocol in the Duke Advanced Research in SS/SDOCT lmaging (DARSI) laboratory.
