Use of Handheld Intraoperative Spectral-Domain Optical Coherence Tomography in a Variety of Vitreoretinal Diseases

BACKGROUND AND OBJECTIVE: The use of intraoperative optical coherence tomography (iOCT) has been described with a variety of imaging devices and techniques. The purpose of this investigation is to examine the role of iVue (Optovue, Fremont, CA), a commercially available, handheld spectral-domain iOCT system, in vitreoretinal surgery. PATIENTS AND METHODS: For this retrospective, observational case series, patients who underwent a vitreoretinal surgical procedure and were imaged with the iVue were identified. Images were qualitatively assessed. RESULTS: Five cases were identified, including an examination under anesthesia, epiretinal membrane, macular hole, retinal detachment, and nonclearing vitreous hemorrhage in the setting of proliferative diabetic retinopathy. CONCLUSION: Clinically useful images were obtained in all cases, though it was difficult to center the scan on the area of interest in the retina. Further work is necessary to improve system design and investigate the ways in which iOCT can aid in vitreoretinal surgery.
